Martindale pilling tester is used to detect the cause of pilling in fabrics

Fiber length and fineness, low twist, fuzzy and bulky yarns, individual yarns, type of weave and type of finish used all contribute to fiber pilling.

The specific influencing factors are as follows:

 ⑴ If the forming speed is greater than the repelling speed, the balls will accumulate on the surface. The rate of balling is related to the number, length, cross-section, yarn density, weave structure, etc. of fibers in the yarn. Anything that causes fibers to slide to the dummy surface will increase ball speed.
(2) The longer the staple fiber, the less pilling. Because fewer fiber ends protrude per unit area and long fibers can also be fixed more firmly on the yarn.
(3) The thicker fibers are stiffer and less prone to pilling.
(4) The cross-section is He-shaped and the surface is smooth, so that the fibers can easily slide to the surface of the fabric, making itr they are going to pill. Irregular cross-section reduces the tendency to pilling.
⑸Low strength fibers can increase the speed of the ball throw.
6 High curl can reduce pilling.
⑺ Air jet is better than ring spun yarn. In ring spinning, the longer fibers tend to concentrate in the center of the yarn, while the shorter fibers are on the outside, causing pilling. Airflow is poorer than ring-spun yarns.
⑻The finer the count, the smaller the chance of pills. The exception is fabrics made of a blend of polyester and wool. Compared to the same blended fabrics, the finer the yarn and the more polyester on the surface, the easier it is to ball.
⑼ High twist can tighten the yarn, with fewer protruding fibers, reducing fiber mobility, reducing pilling. ⑽In mixed fabrics, the higher the polyester content, hoe easier it is to pill.
⑾ The less hairy the yarn, the less pilling.
⑿ Single Mecca yarn is easier to pill than double ply yarn.
⒀ Knit fabrics are more prone to pilling than woven fabrics due to the large surface area of ​​exposed yarns.
⒁Compared to twill weave, plain weave is less prone to pilling due to the high number of interweaves and short crotch length.
⒂ Light fabrics containing a small amount of low quality cotton are more prone to pilling than heavy fabrics. Therefore, different fibers, yarns and fabrics will cause pilling. In theory, choosing the best conditions for each influencing factor can reduce pilling, but in most cases these affect other properties of the fabric.

The causes and prevention measures of textile pilling can be indicated as follows:
Pilling occurs in wool, polyester/wool and cottonnen fabrics, but is more common in polyester/cotton or polyester/viscose blended fabrics. Polyester/cotton/polyester/viscose blend fabrics are preferred by users for their durability, aesthetics and comfort. However, these benefits are overshadowed by the fact that they are more prone to pilling than natural fibers. However, this phenomenon does not occur in fabrics and clothing made of polyester filaments, and short fibers are easily brought to the surface by friction during wear and washing, forming small balls. In theory, the following steps lead to pilling:
①Due to mechanical action, the fibers are stretched to the surface of the fabric and form fluff;
②The fluff is entangled in balls, which are connected to the surface of the fabric by solid fibers;
③During the process of rubbing, washing, wearing and cleaning, continuous mechanical action causes the ball to fall off.
Any staple fiber will pill, and polyester staple fiber pilling is the most serious. This is mainly due to the high strength and bending resistance of polyester, so that the formed ball is not easy to fall off the fiber, and the static electricity of polyester can easily absorb foreign particles to cause pilling.

Select the following methods to prevent pilling: 1. Select fibers that do not pill easily during yarn and fabric production.
2. Add lubricant Lubsoft to prevent friction during pre-treatment and dyeing in the jet dye machine; 3. When dyeing mixed fabrics of cotton and polyester/cellulose fibers with reactive dyes in the jet dye machine, crystalline sodium sulfate of table salt can be used instead. 4. Appropriate heat setting for polyester/cellulosic fiber and polyester/wool blend fabrics to allow the yarn to cure properly and overfeed. 5. Brushing timess shaving can remove surface fibers and protruding fibers. 6. Scorching on both sides can remove surface fibers and protruding fibers.
7. For polyester and polyester/cellulosic fiber fabrics, partial alkali reduction of polyester components can reduce the strength of polyester so that the granules are easy to remove.
8. Use Cellusof-L for cotton and polyester/cellulose fiber blends and use suitable biological enzymes for polishing for wool or polyester/wool blends.
9. Treat polyester/cellulose fibres, polyester/wool and cotton fabrics with the special additive Saraglow-CL in a jet dyeing machine and wash the finished garments with water in a tumble dryer to remove surface fibres.
10. The dosage must be appropriate to avoid excessive softness and lubrication, otherwise it promotes the movement of fibers to the surface and causes pilling.
11. Finishing with special finishing agents, such as: Sarafeel-jy/Sarafeel-763, a special silicone compound, which can soften fabrics and improve pilling through film formation; Sarasoft-MR-Silicone Polymer finishing agent, has film-forming properties and can improve abrasion resistance; Garfinish-As has anti-pilling and anti-scratch properties and can be added to traditional liquid finishing formulations.
