Introduction:
Do you know what is the working hour for a merchandiser in Bangladesh . Believe or not Merchandisers in Bangladesh are working more than 13-14 hours as regular job & some time much more . Always they are busy with hundreds of work schedule but nothing can be completed within office hour . So they have to stay in work place up-to late night . You can’t say this is only inefficiency of their profession because most of the time they are over loaded . The owners are having a cost minimizing tendency so they hire a Merchandiser instead of two or more without considering the demand of work load . As a result a merchandiser always fail to enjoy their regular life & gets tired . They loss their innovative force & feel exhausted in older years . We often see merchandiser who aged beyond 45-50 either loss their job or stay in the organization as a good for nothing . Owners don’t want to pay higher salary for him though they already have taken valuable energy ,time & work force in early age . This is really shocking that now they feel you are not to be used . Yes , right now we have to think how can take the best from our life period . Whatever the age we should have to keep energy & not to be exhausted . We can think for us from today & prepare a new deal for your career . To make easy & to be smarter merchandiser in our way of working please let us do something different . Today we are going to discuss how you can manage your thousands of job in a limited period of hours & can keep maximum energy .
Merchandiser work in office
Merchandiser work in office
1) Make a list of all your job:
This is very important what you are doing to keep it in your daily schedule . It would be better to make schedule 1st daily than weekly & finally monthly . Why this is important to do list ? First of all we are human being. So this is not possible to keep everything in our mind & to do the thing in priority basis . Usually a Merchandiser has to work through lots of stress as well as difficulties . For which this is not surprising if you see he is forgetting to do some most important task that should have to perform in first priority . The second thing is – when we see thousands of task that we have to perform within a very short period of time our nerves gets week . we feel exhausted & fatigue . So by the making schedule we can easily prioritize your task & get the most important & urgent thing .

The below diagram will help everyone to do list in the work priority . This may take little time to make your habit with the method but believe me the method is really effective .


Urgent
Not Urgent
Important
  1. Fabric booking
  2. Yarn procurement
  3. Price for new query
  4. PP sample submission
  1. Recape meeting with senior
  2. Production up-date
  3. Bulk Lot shade approval
  4. Factory visit & get the production status
Not Important
  1. File & Sample organizing
  2. System Up-date
  3. Price review
  1. New product collection
  2. Develop product knowledge
  3. Knowing up-date product status of other customer
2) Don’t put task for tomorrow:
Just keep in mind that tomorrow never come . If you are thinking today is for relax & tomorrow will be your busy day that would be unrealistic . Actually it does not happen because tomorrow you will see new task has added to do & in this way task will be more . One day without doing your important task means you are going to burden yourself for tomorrow .So whatever you think that should have be done today from your task priority list , do it immediately . Never wait for tomorrow.

3) Check double/Triple which is mathematical:
Usually a merchandiser works in a rush movement so sometimes it is not possible to do all the mathematical task in cool mind . Suppose you are going to book fabric or yarn . Here you have to calculate some figure to get the fabric amount that can be used for bulk . but for the all rush movement you made little mistake & proceeded for procurement . Your delivery time may be very short so without any revision of your booking hand over it to supplier & finally when the fabric in-housed it was identified what mistake you have done earlier during fabric booking. May be you mistake in color name or fabrication is wrong . Instead of 90/10 cotton/elastane you received fabric in 100% cotton . This is due to you worked in an old work order sheet where fabric was booked in 100% cotton & in the new sheet fabrication was not changed . The mistake is very little but outcome is devastating . To save time you did not give a cross check on the sheet & now all of your production schedule has gone to drain . This is really measurable when you will see your fabric is in-housed but cannot meet delivery date . Now again book the fabric newly & shipped the goods by air due to you missed delivery date . Actually this would not happen if you are careful & taking extra time give revision twice or triple . If you can take help from your colleague to see the booking as second party . This will help you to avoid extra hassle & to utilize your time properly . Here you can keep some key for cross check . cross check means the figure that should be off course changed in new booking . For fabric booking check the below
  • Fabric composition .
  • Fabric construction .
  • Fabric color .
  • Fabric width .
  • Finally Fabric Qty .
4) Don’t miss any mail:
A single mail can change total output . If you are not properly look into your mail & work through of it you may miss some important information . So read your every single mail & share the mail with all the relevant party . Don’t keep it in your box only . If you have some mail that you should give answer please keep it in red mark so that it will not go out of your track .

5) Don’t do a task twice:
This is actually relevant to point no 3 . Take extra time to do anything but don’t think you will do it twice or 2nd time you will get the opportunity to do it again . Suppose you are in great rush hour to submit sample, giving mail repeatedly to factory to submit the sample in certain date along with lots of phone call . Finally received it but factory made mistake to follow earlier comments what buyer has given . That means the sample is rejected & is not ok to send buyer . Again the sample is made following the comments but it was late one week . So all your production plan got delayed because of not to submit the sample due date . Actually from beginning you could avoid all the delay & wrong thing . If you could take just extra 15 minutes to check the change that buyer want in the earlier comment or before stitching you could visit factory & check everything that sample is going in right way it would help you to save time & energy . Take extra minute to do anything .

5) Do extra work just one day:
In your ‘to do list’ you got some task that has to be done by this week but you are engaged so much in some important meeting so could not able to work on weekly schedule . Now what can you do ? Use only one day to work extra hour in the week . Never think to do it every day . You can work extra hour at the last working day of a week so that the next day you can do relax & enjoy family . So a day for a week can be your extra hour to finish pending task . This will help you to minimize your work load .

6) Make a good relation with everyone to get job done early:
This is said that everyone is king in his own work place . May be the person is a lab in charge . As job routine he is bound to do what are all your requirement because owner assigned him to do job what merchandiser demand in related to lab issue . But this is also true he keeps schedule in his every day to do list as per queue . So you cannot ask for lab dip just in a day where as he has hundreds of lab making in the schedule . Here if you have good relation with the person it will be easy to get lab dip though you are not in the queue . So make a good relation to all the department even a person who is in a worker level . Never underestimate any one . Respect all to get respect from every one .

7) Utilize down time:
Usually success comes from the time which is not usually counted by the commners . Because to do extra work there are no alternative way except utilizing down time . Down time means – the time what you are just doing nothing or doing one more job simultaneously . Suppose you are just stucked in the traffic jam which is very common in our city life . It is often seen people are just seating in the jam & trying to blame the system . But if you want to use your down time ,this can be an opportunity for you . Take journal or book & start reading . That means all of your time can be used properly . On the other hand you can use down time in different way . May be you are having lunch .This may take 15 minutes to finish . During your lunch time you can listen radio news in your mobile . This will help you to get up-date information about what is happening around you . your busy life will not stop you to be up-dated in a new day .

8) Keep proper tracking whatever your are doing:
We are human being . So sometime this is not possible to keep everything in our memory . In the merchandising no one can you say everything is in tracking unless he follows some basic rules . The basic rules of keeping track is ‘put down notes’ in your excel sheet or note book . Make a excel sheet & put all your information whatever you receive every day . Put the date on the stuff what you receive from buyer & what you send to buyer . keep same information on the submitted items to avoid any kinds of confusion between you & buyer . Keep your sample / swatch in a place where anything may not be lost . Make sure to keep separately all your important items to be understood by everyone or to get it in your absence . You can follow below rules to keep tracking .
  • Put date on everything .
  • Up-date & review your excel sheet every day .
  • Keep hard copy of all your important mail . Because some time you may not be in net service when the information is required .
  • Put your excel saved in your draft mail to find the data available incase computer is got effected by the harmful virus .
  • Don’t forget to send a mail to any consignee whenever you are sending sample /swatch .
9) Keep all approval in hand :
Don’t miss any of your approval that received from buyer . Suppose fabric quality , sample or trims whatever comments on submission please keep in proper way so that it will not loss . If you have several submission on particular item that sent to buyer make sure to keep date & comment for each submission . This will help you not to be haphazard among the all submission .

10) Don’t miss to put anything on mailing correspondence :
Some time you may feel unnecessary to put things in the mail whatever discussion you did in phone or verbal communication with someone . In reality this is very important & never delay to put the content you discussed in a written document /mail to prove the conversation . Suppose a trim supplier confirmed you in a particular date to deliver the item over the phone . As you feel the commitment is definitely will be met so did not put the conversation in mail . But in the due date you get the supplier denied to deliver the item & ignored his commitment . So if you could keep the commitment in a written document it would be easier to hold him . Believe me this is most effective to make easy your job ,keeping things in mail .

11) Keep clean your desk :
A merchandiser has to do hundreds of job in a day so this is quite natural if his desk gets occupied by lots of stuff like paper , swatch , trims etc. Every day new items come to you & your surrounding is seeming a little store of fabric , sample & with others thing . You feel over loaded as your desk is overloaded by working stuff . How can you clean your desk to make free from all kinds dizzy materials ? This is really challenging for you rather than your daily job . Some time we feel keeping things on desk is not a problem & this is actually to get the things in hand . Believe me if your boss or others want to see anything in your obscene from the desk they might be puzzled & confused what to take & what to not take . So use only 30 minutes to keep clean your desk & put all the stuff in particular folder so that anyone can find any important item . This will make your job easy . Remember ‘The true competition lies is not what we do, but how we do it’.

12) Take suggestion if you are in trouble :
The universal truth is – two head is better than one head . That means if you are trying to do something counsel with other so that you can work more efficiently with less error . Never think you are the perfect one & no need to take suggestion from others . In other way this is called – cheer leader .Cheer leader is your boss , co-worker , friend so If you want to be in track & to do the correctly must discuss with fellow people. Definitely this will ease your job .

13) Filing & updating :
A merchandiser means lots of file & documents, so maintaining file for the each order & keeping the necessary stuff is very important . Actually this is little similar to the point ‘Keep clean your desk’. However this is specifically to put the thing in file properly . How your file will look ? where to keep it ? what name can be given to each file ? there are lots of issue that should have to take in consideration if are really interested to be a smarter merchandiser . To do your task in smart way you need to think about your file . Suppose where to keep it ? always try to keep your important file close to your hand so that you might not be haphazardly looking for your file when you need . Here some suggestion how to keep file –
  • Put a name for your file in bold letter .
  • Put all the information on top of the file ,example – style name , PO no , Qty , & a garment sketch .
  • Your file should be clean & need to keep all the paper in a chronological way .
  • For easy understanding you can use divider to keep separate the subject matter .
  • Use folder to keep different submission ,off course don’t forget to write date .
  • Use metal cliff so that the file can be use for long time .
  • If you receive revised PO please make sure to keep it in file & keep a cross mark on old PO .
  • Never remove any paper from your file ,if Pos are revised keep date on old file & write on top of it why this is changed .

Technical Textiles:
The technical textiles are defined as textile materials and products manufactured primarily for their technical performance and functional properties rather than their aesthetic or decorative characteristics.

Categories of Technical Textile:
Depending on the product characteristics, functional requirements and end-use applications the highly diversified range of technical textile products has been grouped into categories:
  1. Agro Textiles (Agriculture, horticulture and forestry)
  2. Building Textiles (Building and construction)
  3. Clothing Textiles (Components of shoes and clothing)
  4. Geo Textiles (Geo Textiles, Civil engineering)
  5. Home Textiles (Components of furniture, household textiles)
  6. Industrial Textiles (Filtration, cleaning and industrial)
  7. Medical Textiles (Hygiene and medical)
  8. Mobile Textiles (Automobiles, shipping, railways)
  9. Oeko Textiles (Environmental protection)
  10. Packaging Textiles (Packing materials)
  11. Protection Textiles (Personal and property protection)
  12. Sports Textiles (Sport and leisure)
  13. Aerospace Textiles (aircraft and space textiles)
What is Aerospace?
Aerospace comprises the atmosphere of Earth and surrounding space. Aerospace is actually a compression of
  1. Aeronautics (the science of flight within Earth's atmosphere) and
  2. Space flight (the movement of a vehicle beyond the atmosphere).
Aerospace embraces the full spectrum of flight, and the aerospace industry manufactures the components and equipment for things that fly.

Aerospace Textiles:
From pilot clothing to plane, textile would be anywhere in aircraft. Aerospace textile is an area of technical textiles that covers special finished products to engineered textiles. It includes the textile containing articles for specific functional requirements to work in aircrafts, space suits, space shuttles, lunar and mars mission, and space transportation.

Raw Material for Aero Textile:

Carbon fibre:
It is the material consisting of extremely thin fibres about 0.0002 - 0.0004'' in diameter and contains mostly carbon atoms as it is produced as the by-product during the cracking process of crude oil.
  • It is also called as graphite fibre.
  • Excellent tensile strength.
  • Heat resistance.
  • Chemical resistance.
Keeping in the view of these properties, these fibres are used as reinforcing moulds, and heat insulating materials.

Apart from this, these fibres are used as raw materials for the manufacture and design of special utility components of aviation machine, space rockets,

Kevlar fibers:
Kevlar is the trade name for Aramid fibres. They are
  • Heat resistant
  • High strength and modulus.
  • Good resistance to abrasion.
  • Good fabric integrity even at elevated temperatures.
  • Corrosion resistance.
  • Malleability.
Kevlar fibres are known for the ability to provide quality and consistency, which are critical for aerospace applications. Kevlar fabrics are used in containment wraps, which perform the important role in preventing the broken engine blades from damaging the aircraft or entering the compartment of the passengers.

Alumina-boria-silica fibres:
Nextel is the trade name for Alumina-boria silica fibers.
  • Retain strength.
  • Flexibility with little shrinkage even at continuous temperatures up to 2012°F (1100°C).
  • Silicon carbide fibre.
  • These fibres are similar to carbon fibres.
  • Heat resistance.
  • Corrosion resistance.
  • Elasticity.
  • Withstand temperature as high as 1500 degree Celsius.
Nylon fiber:
Nylon 6,6 is made of hexamethylene diamine and adipic acid, which give nylon 6,6 a total of 2 carbons. Heat resistance.
  • Friction resistance.
  • Melting point of 256 degree celsius.
E- Glass:
E- Glass or electrical grade was originally developed for stand-off insulators for electrical wiring. It was later found to have excellent fiber forming capabilities and is used almost exclusively as the reinforcing phase in the material commonly known as fibre glass or glass fiber.

The essential properties of textile composites in aerospace applications are:
  • High specific modulus.
  • High specific strength.
  • Resistant to chemicals and organic solvents.
  • Good fatigue.
  • Thermal insulated and thermal resistant.
  • Impact and stress resistant.
  • Better dimensional stability and conformability.
  • Low flammability.
  • Non-sensitive to harmful radiations .
Other Properties Required for Aerospace Textiles It is also need to consider incorporating maintainability requirements into aerospace materials. Some of the properties desirable from maintainability point of view are;
  • Washable.
  • Abrasion resistance.
  • Tear resistance.
  • Moisture resistance.
  • UV stabilization.
  • Material standardization.
Based on the applications, textiles used in Aerospace are broadly divided into,
  1. Aircraft Textiles.
  2. Space Textiles.
The textile articles being used in aircrafts are mainly for the below purposes.
  • Wings, Body parts.
  • Curtains.
  • Upholstery fabrics.
  • Wall covers.
  • Head set.
  • Floor carpet/covering.
  • Seat covers.

What is spinning?
  • The term ‘spinning’ may be defined as the process or processes used to produce either fibres or filaments from natural or synthetic polymers, or convert natural or man-made fibres (mmf) and filaments into yarns by twisting or other means of binding together the fibers or filaments. 
  • This provides a relatively fine continuous length of thread that has properties suitable for conversion into a fabric form or for use directly for sewing or rope making. The spinning processes employed to make fibres or filaments may be generally classed as polymer extrusion methods.
Air Jet Spinning:
  • Air-jet spinning is the latest in a string of technological developments intended to increase production speed and flexibility. This technique is also known as fasciated yarn spinning. Air-jet spinning system which consists of a 3-over-3 high-speed roller drafting unit, The basic jet design is also shown. This has a central cylindrical channel (the spinning channel) through which the fibre ribbon from the drafting unit passes. Inclined to the channel axis but tangential to its circumference are four nozzles through which compressed air is injected into the channel, creating a vortex airflow. 
    Twist
  • Each jet of compressed air entering and expanding into the channel has two velocity components of airflow: V1, a circular motion of the air around the channel circumference, and V2, the movement of the air to the channel outlet. The suction at the jet inlet created by V2 gives automatic threading-up of the spinning process. Provided the drafted ribbon is not tautly held between the front drafting rollers and take-up rollers, the V1 component of flow rotates it, inducing a false-twisting action via a rotating standing waveform (a spinning balloon) while V2 assists movement of the twisted ribbon through the channel. 
Flowchart of Air Jet Spinning
  • The nozzles of the first jet are set to give a counter-clockwise vortex producing a Z–S false-twist action; the second jet gives an S–Z false-twist action. The pressures applied to the jets are such that jet 2 has the higher twisting vortex. Although the jets impart a false twist, while doing so they do not have a positive hold on the ribbon being twisted. Because of this the Stwist from jet 2 propagates along the twisted ribbon and nullifies the Z-twist from jet 1, leaving some S-twist to travel towards the nip line of the front roller.
Air Jet Spinning
 Operation Principle of Rieter Two- Nozzel Air-Jet Spinning:
  • As shown in a draw frame sliver fed from a can is passed to a drafting arrangement , where it is attenuated by a draft in the range of 100 - 200. The fiber strand delivered then proceeds to two air jets arranged directly after the drafting arrangement. The second jet is the actual false-twist element. 
    Diagram of Air Jet Spinning
  • The air vortex generated in this jet, with an angular velocity of more than 2 million rpm, twists the strand as it passes through so that the strand rotates along a screw-thread path in the jet, achieving rotation speeds of about 250 000 rpm. The compressed air reaches the speed of sound when entering the central canal of the false-twist element. Since the axial forces are very low during this rotation, only low tensions arise in the yarn. 
Twist direction of Air Jet Spinning
  • The ability of the vortex to impart torque is so high that the turns of twist in the yarn run back to the drafting arrangement. The fiber strand is therefore accelerated practically to full rotation speed as soon as it leaves the front roller. 
  • The edge fibers which ultimately bind the yarn together by becoming wrapping fibers are in a minority. 
  • For process reasons, they do not exceed about 5% of the total yarn mass. These edge fibers exhibit relatively few turns of twist in the same direction as the falsetwisted core fibers or can even be slightly twisted in the opposite direction. This is partly ensured by causing the strand to emerge from the nip line in a broadly spread form, but mainly by generating in the first jet a vortex with an opposite direction of rotation to the vortex in the second jet. 
  • This first vortex is in fact weaker in intensity than the second and cannot really affect the core fibers, but can grasp the edge fibers projecting from the strand at one end. Since the first vortex acts against the twist direction generated by the second jet, it prevents the edge fibers from being twisted into the core or even twists them in the opposite direction around the core fibers. As the strand runs through the second jet, the following occurs.
  • The turns of twist generated by the jet are canceled in accordance with the falsetwist law. The core fibers, i.e. the vast majority, no longer exhibit any twist; these fibers are arranged in parallel. On the other hand, the edge fibers (which previously exhibited no twist, relatively little twist, or even twist in the opposite direction) receive twist in the direction imparted by the jet, as determined by the law of false twist; they are therefore wound around the parallel fiber strand. They bind the body of fibers together and ensure coherence. A twist diagram prepared by Dr. H. Stalder demonstrates this twisting procedure .
  • The resulting bundled staple-fiber yarn passes from the take-off rollers through a yarn-suction device and an electronic yarn clearer before being wound onto a cross-wound package. The two nozzle air-jet spinning system represents a very interesting process, which has already been introduced into practical operation with some success.
SPECIFICATION OF THE MJS MACHINE:
  • Spinning positions per machine .......up to 72 (SINGLE -sided machine)
  • Delivery speed ..........150 - 300 m/min
  • Raw material ............synthetic fibers and blends (combed cotton)
  • Count range .............7.5 - 30 tex; Ne 20 - 80
  • Feedstock type ........drawframe sliver
  • Type of yarn ............bundled single yarns
  • Yarn characteristics .......reasonable strength, low hairiness, rough outer surface
  • Field of use ........ladies‘ outerwear, shirting, material, sheets
  • Remarks ...........low production costs, low personnel demand, no rapidly rotating parts, three drawframe passages necessary
YARN CHARACTERISTICS OF AIR-JET SPIN YARN
The yarn character is slightly different from that of ring spun yarn. It is somewhat:
  • weaker,
  • stiffer, and
  • harder.
The hardness can be reduced by using finer fibers and by treatment of the finished product with a softener (e.g. with a silicone).

Additional points of comparison with ring-spun yarn are:


Positive:
  • Good evenness (like ring-spun yarn);
  • Good abrasion resistance;
  • Low tendency to pilling;
  • Low snarling tendency;
  • Shrinkage similar to that of ring-spun yarn;
Negative:
  • Higher resistance to bending;
  • Slightly lower covering power;
  • Wrapping fibers not uniformly distributed over the length; sometimes there are slightly more on the surface, sometimes slightly fewer.
  • A large number of wrapping turns impart more strength but at the same time greater hardness. Synthetic fiber yarns and blends of synthetic fibers and cotton with a proportion of synthetic fibers of at least 50% achieve strength levels of about 80% or more relative to ring-spun yarn.

Yarn Clearer
Yarn clearer is the device which is used to remove the following faults of yarn in order to increase the yarn quality and weaving efficiency.

Wilson Yarn Clearer
  • The occurrence of many slubs (thick place in yarn) in the yarn was well known to the weavers in the Hollins factory in Glasgow for they knew that much labor had to be spent after the weaving on “burling and mending” of the fabric in order to remove as many faults as possible. But in the spinning mill at Pleasley Vale yarn clearing was regarded as an undesirable and costly process. 
  • The yarn production people in Pleasley believed that their slub catchers were effective - it was obvious to them that a slub up to an eighth in diameter could not pass through a slot only 10 thousandths of an inch wide. They never saw the evidence of their erroneous belief since they did not see the woven fabric with the many slubs that had passed through their yarn cleaners. 
  • Peter Wilson realized that the true cost of the defective yarn clearing which was currently being practiced warranted the development of a better yarn clearer even if it cost as much as £5. The factory management, used to spending only a shilling or two on their yarn clearers held up their hands in horror at the thought of such an expense. There was some justification from their own narrow cost standpoint, but on an overall company view it was good business. 
    Wilson Yarn Clearer
  • Thomas Holt and Co, a Rochdale cone winding engine maker, agreed to promote the Wilson Yarn Clearer commercially and a production prototype was made and taken to Erricson Telephone Ltd (ETL) who agreed manufacture the device. Their unit price of £13 for an initial run of 2000 was achieved by using printed circuitry that was then in its infancy and initial order was placed for 2000 units.
  • In September 1958, Thomas Holt showed the Wilson Yarn Clearer at the International Textile Exhibition in Belle Vue, Manchester as the “Yarnspec”, which was believed to be the World’s first commercially viable yarn clearer. 
  • By about 1959 Thomas Holt had sold some 12 000 units but Thorn Bendix, a subsidiary of ETL dealing with textile applications, began production of a transistorized version which included some 12 or more transistors and superseded the much bulkier Yarnspec. A few years later sales of £400 000 p.a. were being achieved by Thorn Bendix and the era of electronic yarn clearing was well and truly born.
Faults of yarn
  • Thick and thin places
  • Slab and neps
  • Loose fabric
  • Foreign material
Types of Yarn Clearer
  1. Mechanical Type
  2. Electronic type
Mechanical Type
  • Conventional blunt type
  • Serrated blade type
Electronic type
Electronic yarn Clearers ensures excellent clearing to be obtained with minimum mechanical stress on the yarn. The places, not possible with the mechanical system are an additional feature of the electronic system. The tamper-proof central adjustment for several spindles leads to a significant saving of time.

Electronic Yarn Clearer Model Myc-2
Mill requirement of yarn clearing controls have been developed for various stages in spinning process to improve the quality of the end product, i. E. Yarn. For this we have piano type autoleveller at blow-room, giving more uniform lap, autolevellers at carding and drawframes to give more uniform sliver etc. But even with all these controls it is not possible to get 100% uniform yarn. The present concept of the yarn depends upon various parameters like count, twist, strength, evenness and nepiness. The definition of the quality yarn is incomplete until the yarn faults are taken into consideration and eliminated.

Capacitance type
Zellweger Uster completely re-invented the yarn clearer with its Quantum clearer. This new clearer is digital, has capacitive and optical sensing capability and gives yarn fault classification according to the Uster Classimate concept. The Uster Quantum clearer can be used in several different modes including: capacitive or optical sensing, capacitive and foreign matter sensing or capacitive and optical combined. Quantum has 100-percent digital electronics, self-calibrating measuring heads, and on-board diagnostics.

Photo electric type

Seletex is a photoelectric yarn clearer which detact and removes various yarn faults in spinning or silk yarn in re-winding process. Photoelectric detector many material , moisture yarn, electric conductors and others.

Comparison between mechanical and electronic clearer:
  • Electronic clearer are more sensitive than mechanical clearers
  • In case of mechanical clearers there is abrasion between yarn and clearer parts but in case of electronic clearers there is no such abrasion
  • Mechanical clearers do not prevent soft slab from escaping through clearer where as electronic type does not allow passing of any types of faults
  • Mechanical type does not break the thin places and the length of the fault is not considered
  • Mechanical clearer are simple and easy to maintain while the electronic clearers are costly and requires high standard of maintenance
USTER QUANTUM 3
USTER QUANTUM 3 is the third generation of the best-selling online quality assurance system for winding machines. These state-of-the-art yarn clearers use Smart Clearing Technology to optimize production efficiency and reduce costs for spinners.
