The pilling of girls' knitted crew neck sweater mainly comes from the scale structure on the surface of wool and other fibers. During wearing and washing, the fibers rub against each other, and these scales will hook together to form pilling. In addition, factors such as knitting process, yarn quality and daily use environment will also affect the degree of pilling. For example, coarser knitting needles may expose more fibers and increase the chance of friction pilling; sweaters are also more likely to pill when worn in dusty environments or in frequent contact with rough surfaces.
Selecting high-quality and specially treated fibers is a key step in anti-pilling. Some new wool fibers, such as wool that has been descaled, have their scales partially removed or passivated, reducing the hooking between fibers. At the same time, wool can be blended with synthetic fibers with good anti-pilling properties, such as polyester fibers and acrylic fibers, in a certain proportion. Polyester fibers have higher strength and wear resistance, while acrylic fibers have better fluffiness and anti-pilling properties. After blending, the advantages of both can be combined to reduce the possibility of pilling and keep the sweater soft and comfortable.
Reasonable knitting process helps to reduce pilling. Using tight and delicate knitting needles, such as high-needle flat needles or twisted needles, can make the yarns tightly combined and reduce fiber exposure. In areas prone to friction such as collars and cuffs, the knitting density can be appropriately increased or a double-layer knitting structure can be used to enhance the wear resistance of these areas and reduce the risk of pilling. For example, the collar is ribbed and the number of needles is increased, which can not only improve elasticity, but also effectively prevent pilling caused by frequent friction of the neck skin.
The post-finishing link is crucial to fight pilling. Through processes such as brushing, shearing and singeing, the stray hair and short fibers on the surface of the sweater are removed to make the surface smoother and flatter, reducing the causes of pilling. Brushing can straighten the fibers, shearing can remove the protruding fiber ends, and singeing can use high temperature to instantly burn off the fluff on the surface, but the temperature and time must be precisely controlled to avoid damaging the main body of the sweater. In addition, anti-pilling finishing agents are used for treatment. The finishing agent can form a protective film on the fiber surface, reduce the friction coefficient between fibers, and further inhibit the formation of pilling.
Proper washing and maintenance can prolong the anti-pilling effect. It is recommended to use mild detergents and avoid using strong detergents or products containing bleach to avoid damaging the fibers. Use gentle mode when washing to shorten the washing time and reduce mechanical friction on the sweater. Avoid wringing vigorously after washing. You can choose to lay it flat to dry or dry it at low temperature to prevent the fiber from being damaged due to excessive stretching or high temperature, which increases the tendency of pilling.
Establish a strict quality inspection system and test the anti-pilling performance of girls' knitted crew neck sweater according to relevant standards. Observe the pilling condition of sweaters and rate them by simulating the actual wearing and washing process. Enterprises should follow industry standards to ensure that the anti-pilling performance of products meets certain requirements and provide consumers with sweater products with reliable quality and neat appearance.
With the development of science and technology, more advanced anti-pilling technologies are expected to be developed in the future. For example, nanotechnology can be used to modify the surface of fibers to make them self-cleaning and anti-friction; or smart fibers can be developed to automatically adjust the surface structure according to environmental changes to reduce pilling. These innovative technologies will bring new breakthroughs to the anti-pilling treatment of girls' knitted crew neck sweater and further improve product quality.
