Knitted Sweater's high-gauge fabrics are generally tighter, so low-gauge fabrics are more prone to pilling than high-gauge fabrics. The fabric with flat surface is not easy to pilling, and the fabric with uneven surface is easy to pilling. Therefore, the pilling resistance of fat pattern fabrics, ordinary pattern fabrics, rib fabrics, and plain knitted fabrics is gradually increased. Dyeing and finishing process: After the yarn or fabric is dyed and finished, it will have a greater impact on the pilling resistance, which is related to dyes, auxiliaries, and dyeing and finishing process conditions. Yarns dyed with tops are prone to pilling; fabrics dyed with jerseys are more prone to pilling than fabrics dyed with yarns; after the fabric is shaped, especially after finishing with resin, its pilling resistance will be greatly enhanced. Scale is a main feature of wool fiber, which makes wool fiber have shrinkage, so the essence of anti-shrinkage finishing is to treat the scale to weaken or lose the directional friction effect. Many Sweaters mainly use chemicals to interact with the scales to damage and soften the scales; or use the resin to spread evenly on the fiber surface to form a film. Thus effectively limiting the effect of the scales, making the wool fiber lose its shrinkage and achieving the purpose of shrinkage resistance. Viscose silk fabric (human silk): The silk surface is bright but not soft, bright in color, smooth to the touch, soft and has a strong drape, but it is not as light and elegant as real silk. After the silk surface is pinched by hand and loosened, there are creases and the recovery is slow. Hoarseness when tearing. After the warp and weft yarns are wet with water, they are easy to break. Pure cotton cloth: Cardigan Sweater cloth has soft luster, soft touch, poor elasticity and easy to wrinkle. After pinching the fabric tightly with your hands and then loosening it, you can see obvious wrinkles, and the creases are not easy to restore to their original shape. Pull out a few warp and weft yarns from the edge of the cloth and twist them to see that the fibers are of different lengths.
