Acrylic fiber (PAN fiber) is a common synthetic fiber widely used in clothing, home textiles, and other fields due to its excellent insulation, flexibility, and light resistance. However, consumers and industry insiders have different opinions on whether acrylic yarn is prone to pilling. This article will provide a detailed analysis of the characteristics of acrylic fiber, the causes of pilling, the pilling performance of acrylic yarn, and how to reduce pilling.
1、 Characteristics of Acrylic Fiber
Chemical structure: Acrylic fiber is a polymer material polymerized from acrylonitrile monomer, and its molecular chain contains a large number of cyanide groups (- CN), which makes acrylic fiber have high strength and wear resistance.
Physical properties: Acrylic fiber has high strength, good wear resistance, and good elasticity and resilience. In addition, acrylic fiber has excellent light resistance and weather resistance, and is not easily faded or aged due to sunlight exposure.
Texture and appearance: Acrylic fiber has a soft texture and looks similar to wool, so it is often used as a substitute for wool. Its fabric has good warmth retention and fluffiness.
2、 Reason for pilling
Ball formation refers to the small ball shaped fiber clusters that appear on the surface of a fabric due to friction. The main reason for pilling is that fibers detach from the fabric surface under friction and aggregate into small balls due to electrostatic forces. Specifically, the reasons for pilling include:
Fiber length: Short fibers are more prone to pilling than long fibers because they are more likely to detach from the surface of the fabric.
Fiber strength: Fibers with lower strength are more prone to breakage under friction, resulting in pilling.
Fabric structure: The density and weaving method of the fabric can also affect the degree of pilling. Fabrics with lower density are more prone to pilling.
Friction conditions: Frequent friction, washing, and wearing can increase the likelihood of pilling.
3、 The pilling performance of acrylic yarn
Fiber length and strength: Acrylic fibers are usually short fibers, although they have high strength, they may still detach from the fabric surface under frequent friction, forming pilling.
Electrostatic effect: Acrylic fibers are prone to static electricity, which can cause the detached fibers to gather together more easily and form small balls.
Fabric structure: Acrylic yarn is commonly used to weave low-density fabrics such as sweaters, scarves, etc. These fabrics are prone to friction during wearing and washing, increasing the likelihood of pilling.
Performance in actual use: In actual use, the degree of pilling of acrylic yarn varies depending on the specific product and usage conditions. Generally speaking, the pilling phenomenon is more obvious in the initial use of acrylic yarn, but it gradually decreases with the increase of usage time.
4、 How to reduce pilling of acrylic yarn
Choose high-quality yarn: High quality acrylic yarn is usually treated with special treatment, resulting in more uniform fiber length and strength, and a lower likelihood of pilling.
Optimizing fabric structure: increasing the density of the fabric and adopting a tighter weaving method can reduce the possibility of fiber shedding, thereby reducing pilling.
