The reason why polyester fabric is easy to pilling is closely related to its fiber properties, mainly because the holding force between the fibers is relatively small, the strength of the fiber is high, the elongation ability is particularly large, especially the bending resistance, the torsion resistance and the wear resistance are good, so the fiber is often easy to slip out of the fabric surface, once the ball is formed on the surface, it is not easy to fall off quickly. In the actual wearing and washing process, the fiber continues to undergo external friction, so that the fiber on the surface of the fabric constantly exposed to the fabric, the surface of the fabric shows a lot of annoying fur, which is fuzz, if these fur can not be dropped in time in continued use, they are entangled with each other, and are kneaded into many ball particles, usually known as pilling.
Factors of polyester pilling:
There are many factors that affect fabric fuzz and pilling, which can be summarized from the following aspects: (1) the fibers that make up the fabric; (2) textile process parameters; (3) dyeing and finishing processing; (4) Taking conditions.
How to prevent pilling of polyester fabric:
First, when blending, try to choose fiber types that are not easy to pilling in the yarn and fabric production process, so that the fabric can effectively prevent pilling.
Second, during pre-treatment and dyeing in the jet dyeing machine, lubricants are added to prevent friction and reduce the probability of pilling of the fabric.
Third, for polyester and polyester and cellulose fiber blended fabrics, part of the alkali reduction operation of the polyester component can properly reduce the strength of the polyester fiber, even if the ball is generated on the surface of the fabric, it can make the ball easy to remove.
