Causes of pilling
Knitted ha pilling mainly stems from the characteristics of yarn fibers and weaving structure. From the fiber perspective, natural fibers such as wool, whose surface scale structures are easily entangled with each other during friction, cause the fibers to gradually free from the main body of the yarn to form pills. Synthetic fibers such as acrylic, although relatively smooth in themselves, will also attract and aggregate due to static electricity when they are constantly rubbed with other objects, leading to pilling. In terms of weaving, the loose weaving structure of Knitted ha gives the fibers more room for movement. When subjected to external friction, such as frequent contact and friction with hair, clothing or backpacks, the fibers in the yarn are more likely to be pulled out and entangled together, forming visible pills, which affect the beauty and texture of Knitted ha.
Traditional anti-pilling technology and limitations
Traditional anti-pilling technology is mostly focused on the treatment of yarn. A common method is to chemically treat the fibers, such as using antistatic agents to reduce static adsorption between fibers, or wrapping the fibers with special resin coatings to make their surfaces smoother and reduce friction between fibers, thereby reducing pilling. However, these chemical treatment methods often have certain limitations. Chemical reagents may affect the properties of the fiber itself, such as reducing the softness and elasticity of wool and changing its natural texture. Moreover, as the number of washings increases, the chemical coating may gradually fall off, and the anti-pilling effect will be greatly reduced.
Progress in new anti-pilling technologies
In recent years, new anti-pilling technologies have continued to emerge. In terms of fiber modification, nanotechnology is used to treat fibers, such as adding nano-scale anti-pilling particles to the fiber surface. These particles can effectively block direct friction and entanglement between fibers without changing the original properties of the fibers. In addition, there are also innovations in weaving technology, and a special tight weaving structure has been developed to reduce the exposure and activity space of the fibers, making the yarn less prone to pilling during friction. Some companies have also cultivated fiber varieties with better anti-pilling properties through genetic engineering, reducing the possibility of pilling from the source.
Comprehensive application and prospect of anti-pilling technology
In order to better solve the pilling problem of Knitted ha, it is often necessary to use a variety of anti-pilling technologies in combination. In the yarn production stage, fiber modification technology is used to improve the anti-pilling performance of the fiber; in the weaving process, the yarn structure is further stabilized by combining the tight weaving process; in the later finishing stage, environmentally friendly chemical additives are appropriately used for auxiliary treatment to enhance the durability of the anti-pilling effect. With the continuous advancement of science and technology, it is believed that more efficient, environmentally friendly and long-lasting anti-pilling technologies will appear in the future, allowing Knitted ha to effectively avoid the trouble of pilling while maintaining its beauty and fashion, meet consumers' demand for high-quality knitted products, and promote the Knitted ha industry to a new level in terms of quality improvement.
