With the development of the times and the continuous improvement of people's living standards, the requirements for clothing have also been continuously improved. It is not limited to warmth, durability, and new requirements have been put forward for comfort, aesthetics, and functionality. The fabric is prone to fluffing and pilling during wearing. This phenomenon not only deteriorates the appearance and feel of the fabric, but also wears the fabric and reduces the performance of the fabric. Fabric pilling process Factors Affecting Pilling Factors affecting fabric pilling are mainly the effects of fiber properties, yarn, fabric structure, dyeing and finishing process, etc. 1. Fiber properties Fiber strength Fibers with high strength, large elongation, high resistance to repeated bending, and strong wear resistance are not easy to be broken or shed when rubbed, but will further entangle with the surrounding hair clumps and hair balls to form larger balls. However, the fiber strength is low, and the formed hair balls are easy to fall off from the surface of the fabric after friction. Therefore, the fiber strength is high and easy to pill. Fiber length Short fibers are easier to pill than long fibers, and long fibers are less prone to pilling than short fibers. The frictional resistance of long fibers in the yarn is greater than that of short fibers, and it is not easy to be drawn out from the yarn. In the same number of fiber cross-sections, the end of the long fiber exposed to the surface of the yarn is less than that of the short fiber, and the chance of being rubbed by external force is small. Polyester filaments have high strength and are not easy to wear and break when subjected to mechanical external force, and polyester filament fabrics are not easy to pilling. Fiber fineness For the same raw materials, thin fibers are easier to pill than thick fibers. The thicker the fibers, the greater the bending stiffness. Friction between fibers The friction between the fibers is large, the fibers are not easy to slide, and it is not easy to pilling. Fiber blends are prone to pilling Especially the blended fabrics of chemical fibers and wool, cotton, and regenerated cellulose fibers are prone to pilling, because the chemical fiber fibers are relatively strong ball fibers and are not easy to fall off. Fiber cross-sectional shape The fiber with special-shaped cross-section has high bending rigidity, is not easy to bend and entangle, and has a low probability of relative contact and friction, is not easy to pull out and entangle, and is not easy to produce pilling. Fiber crimp The more crimped the fiber is, the less likely the fiber is to stretch when twisting, and the fiber is easy to loosen and slip during the friction process, forming plush on the surface of the yarn. Therefore, the better the curl of the fiber, the easier it is to pilling. 2. Yarn The main factors that affect the pilling of fabrics are yarn hairiness and wear resistance, which involve ...
