The main factors affecting fabric pilling are the following:
Length of fiber: fabrics woven from longer fibers are lighter than fabrics woven from shorter fibers; due to the small number of fiber ends per unit length, there are fewer fiber ends on the exposed yarn and fabric surface; The cohesive force is large, and the county committee is not easy to slide out to the surface of the yarn and fabric.
Fineness of the fiber: The coarse fiber is less likely to pilling than the fine fiber. The yarn spun from the coarse fiber has a small number of fibers per unit area, and the fiber ends on the surface of the exposed yarn and the fabric are less; in addition, the thicker the fiber, the harder it is, and the fibers erected on the surface of the fabric are less likely to entangle into balls.
The degree of crimp of the fiber: the fiber has more curl, the cohesion between the fibers is large, the friction is increased, and the fiber is not easily released to the surface of the fabric, so that it is not easy to pilling.
Cross-sectional shape of the fiber: The cross-sectional shape of the fiber is close to a circular shape, and the cohesive force between the fibers is small, and the shaped fiber having a fiber cross-sectional shape close to a triangle or a polygon is easy to pilling.
Fiber strength, elongation and elasticity: high fiber strength, high elongation, easy to break off when rubbed, and easy to entangle into a ball after fluffing.
The twist of the yarn: the yarn twist is large, the fibers are tightly bound, and the degree of pilling of the fabric is reduced.
The structure of the fabric: the knitted fabric is easier to pilling than the woven fabric.
In addition, the finishing of the fabric and the way of washing and washing also have an effect on the pilling degree of the fabric.
