Why Do Textile Pilling And How To Prevent It?

Pilling occurs in wool, polyester / wool and cotton fabrics, but most of them appear in polyester / cotton or polyester / viscose mixture.

In matter.

Polyester / cotton / polyester / viscose blended fabric is favored by users because of its durability, beauty and comfort.

However, these advantages are snubbed because they are easier to pilling than natural fibers.

However, fabrics made of polyester filament are

This phenomenon will not occur. Because of the friction between wear and washing, short fibers can easily bring fibers to the surface and form small balls.

In theory, the following steps lead to pilling: (1) the fibers stretch to the surface of the fabric and form pubescence due to mechanical action;

Surface is connected; 3. During friction, washing, wearing and cleaning, and continuous mechanical action, the ball will fall off.

Any short fiber will pilling, and the pilling of polyester staple is the most serious.

This is mainly due to the high strength and high bending resistance of the polyester, making it difficult to form the ball from the fiber, and the static electricity of the polyester is easy to absorb foreign particles to produce pilling.

Fiber length and fineness, low twist, hairy and bulky yarns, Dan Gensha, weaving type, and type of finishing agent all promote fiber pilling.

The specific influencing factors are as follows:

If the formation speed is greater than the rate of falling off, the ball will accumulate on the surface.

The rate of ball formation is related to the number, length, cross section, yarn quality and fabric structure of yarns.

Any factor that causes the fiber to slide to the surface of the yarn can increase the ball rate.

2. The longer the length of staple, the less pilling.

Because the ends of the fibers protrude on the unit area are less, and the long fibers can also be more firmly fixed on the yarns.

(3) the coarse fiber is rigid and is not easy to take off.

The shape of the cross section is shaped and the surface is smooth, so that the fibers can slip to the surface of the fabric easily and thus pilling.

Irregular cross section can reduce the pilling trend.

Low strength fibers can increase the dropping speed of pellets.

High curl can reduce pilling.

The air-jet yarn is better than the ring spinning yarn.

Ring ingot

Longer fibers tend to concentrate in the middle of the yarn while the shorter ones are on the outside, resulting in pilling.

Air flow is worse than ring spinning.

The smaller the number, the less likely it is to pilling.

The exception of polyester / wool blended fabrics is that the finer the yarn and the more the surface polyester, the easier the ball is.

The high twist enables the yarn to be more compact, with less prominent fibers, less fiber mobility and less pilling.

In the mixed fabric, the higher the polyester content is, the easier it is to pilling.

It is not easy to pilling when the yarn hairiness is small.

Easy to pilling of yarns than those of double strands.

The knitted fabric is easier to pilling than the woven fabric due to the large surface area of the exposed yarn.

Compared with twill weave fabric, plain weave fabric is difficult to pilling because of its large number of interweaves and short cross length.

A lightweight fabric containing a small amount of low-grade cotton is easier to pilling than heavy fabric.

Therefore, all kinds of fibers, yarns and fabrics will produce pilling.

Theoretically, the best conditions to choose the various factors can reduce pilling, but in most cases, these will affect other properties of the fabric.

The following methods can be used to control pilling:

1. Choose fibers that are not easy to pilling during yarn and fabric production.

2, in the jet dyeing machine before the pretreatment and dyeing, add lubricant Lubsoft to prevent friction.

3. When using reactive dyes dyed cotton and polyester / cellulose fiber blended fabric in jet dyeing machine, sodium sulfate can be used instead of common salt.

4.

Cellulose fiber and polyester / wool blended fabrics are properly thermally shaped so that the yarn can be shaped and properly fed.

5, shearing at the same time brushing, can remove surface fibers and prominent fibers.

6, both sides are singled to remove surface fibers and protruding fibers.

7. For polyester and polyester / cellulose fiber blended fabrics, partial alkali reduction of polyester components can reduce the strength of polyester, so the balls are easy to remove.

8. Cotton and polyester / cellulose fiber blended fabrics were made of Cellusof-L; wool or polyester / wool blended fabrics were polished with suitable enzyme.

9. Polyester / cellulose fiber, polyester / wool and cotton fabric were treated with special assistant Saraglow-CL in jet dyeing machine. The clothes were washed with rotary cage to remove surface fibers.

10, dosage should be appropriate to avoid excessive softness and lubrication, otherwise it will cause fiber to move towards the surface and cause pilling.

11, finishing with special finishing agents, such as Sarafeel-jy/Sarafeel-763, special silicone compound, can give fabric softness and improve ball making through film forming. Sarasoft-MR organosilicon polymerization finishing agent has film forming property and can improve abrasion resistance. Garfinish-As has the characteristics of anti pilling and scratch resistance, and can be added to the traditional finishing liquid formula.
