What Are The Reasons For Pilling Cashmere Sweaters?

Author:QINSUN Released in:2023-07 Click:99

Cashmere sweaters can be seen everywhere, and they are also favored by the people. Some people like the thermal performance, and some people like the beauty and body shape. There are too many reasons to love it. The biggest drawback, however, is that it is easy to pill. The pilling of cashmere sweaters is not only related to the properties of the cashmere fibers and the structure of the fabric, but also influenced by the consumer\'s wearing habits.

1. Fiber yarn:
The fineness, length and crimp of cashmere fiber are important technological characteristics. Compared to wool, cashmere has a smaller fineness, shorter length and fewer wrinkles. The cohesive force in the yarn is small, the exposed hair is more, and the fiber slips and waxy slips out of the fabric under the action of external force, resulting in fluff and pilling. Second, the milling and friction coefficient of the fiber is small, and the friction becomes weakInter-fiber drag is reduced. However, due to the shell structure of cashmere fibers, cashmere easily slips out of pure cashmere or wool blend fabrics. When the aggregates of fibers are subjected to non-directional external force, the fibers are easy against the force of the scales to continuously migrate to the root, resulting in fluff. Due to the interlocking between the scales and the elasticity of the fiber body, the fibers are tangled and pilled. , also caused the felt shrinkage caused by animal fibers.

Cashmere fibers have poor electrical conductivity. When clothes are worn, the fibers rub against each other, causing charges to build up on the fibers, resulting in static electricity. Fibers with high dielectric coefficients are positively charged and vice versa. For example, when chemical fibers rub against cashmere, the chemical fiber becomes negatively charged, while the kasilver fiber is positively charged. Fibers with different charges attract each other, which can easily lead to fabric shedding and pilling, especially in dry weather.
The more the fiber has shrunk, the more difficult it is for the fiber to stretch during spinning, and the fiber tends to loosen and slip during the friction process, causing lint to form on the surface of the yarn is formed. For this reason, the better the fiber pleat, the easier it is to pill. The finer the fiber, the more fiber ends are visible on the surface of the yarn, and the better the fiber softness, so the thin fiber is easier to tangle and pill than the thick fiber. In terms of fiber length, shorter fibers are easier to pill than long fibers, because there are more free fibers, and the friction and cohesion between short fibers are smaller, the fibers easily slide to the surface of the fabric, and it is easy to produceren Pilling phenomenon.

The twist of the yarn and the degree of smoothness of the surface also have a major influence on the pilling. For the high twist yarn, the cohesion between the fibers is tight. The bulb phenomenon is reduced; since the cashmere sweater is a soft fabric, too high a twist will make the fabric hard, so it is not possible to prevent pilling by increasing the twist. Affected by the smoothness of the yarn, the smoother the yarn, the shorter and less hairy the surface, so the smooth yarn is not easy to pill.

2. Fabric texture:
The fabric with loose texture is easier to pilling and pilling than the fabric with tight texture. When the fabric with tight texture rubs against external objects, it is not easy to produce hair. , and because of the high friction resistance between the fibers, it is not easy to slide to the surface of the fabric, so that the phenomenon of pilling can be reduced. Sthigh thickness fabrics are generally tighter, so low thickness fabrics are easier to pill than high thickness fabrics. The fabric with a flat surface is not easy to pill, and the fabric with an uneven surface is easy to pill.

3, the influence of the dyeing and finishing process:
After the yarn or fabric is dyed and finished, it will greatly affect the pilling resistance, which is related to dyes, auxiliaries and dyeing and finishing process The yarn dyed with hank yarn is easier to pill than the yarn dyed with loose wool or wool top; the fabric dyed with jersey is easier to pill than the fabric dyed with yarn; after the fabric is formed, especially after resin finishing, the anti-pilling properties will be greatly improved.

4, the influence of wearing conditions:
The pilling phenomenon must proceed from the mechanism of textilepilling. During the wearing process of the cashmere sweater, due to the friction exerted by the outer cover (like a jacket), one end of the shorter fiber in the yarn slips out and entangles in balls on the surface of the fabric. However, cashmere fibers are thinner and shorter than wool fibers. In addition, regular cashmere sweaters are carded products, and the short fiber content in cashmere yarn is relatively high, making it easier to \"snap out\" and entangle with each other.
So if the cashmere sweater is worn indoors, the lining of the matching coat should be smooth, not too rough or hard, and hard objects or pens should not be put in the inner pocket, so as to avoid local friction and friction. pilling; Do not rub the tabletop, sleeves and armrests of the sofa, backrest and sofa for a long time. The wearing time should not be too long. Pay attention to intermittent and alternating wear to maintain elasticityrepair and prevent damage from fiber fatigue.

 After the cashmere sweater has a pilling phenomenon, please do not pull it by hand. The correct way is to carefully cut the lint ball with scissors after washing. The loose fibers will fall off and the pilling phenomenon of cashmere sweaters will gradually disappear.
