It is normal for polypropylene yarns to play ball. Fabrics will more or less be troubled by pilling. The most important reason is the characteristics of the fibers themselves.

Polypropylene is a Chinese name for synthetic fiber isotactic polypropylene fiber made from propylene, a by-product of petroleum refining, also known as polypropylene fiber. It is rich in raw materials, simple technology, low cost features. However, polypropylene yarns made of synthetic fibers are more pliable than natural fibers and man-made fibers, and they are more likely to become entangled after fluffing.

Because the friction between yarns and different fabrics and the static electricity of polypropylene yarn fabrics will cause fuzzing, we usually use sticky tape to stick the hairballs away. In fact, this method does not cure the symptoms, but also starts from the quality of the yarn itself. In fact, improving the softness of polypropylene yarn can well suppress the problem of yarn picking and pilling.

So far, there are three methods for improving the softness of polypropylene yarns, and they are all in the spinning process:

The first method is to soften the yarn through traditional mechanical methods, mainly through soft yarn treatment, to destroy the glue film and express the softness. The disadvantage is that this method can easily lead to pilling and fluffing of polypropylene yarn.

The second method is to increase the moisture regain of the polypropylene yarn, but pay attention to the range, if the large area of the test will cause the polypropylene yarn to mold, and the softness improvement is not obvious. Or add appropriate softeners during spinning, which also improves the softness of the yarn.

The third method is similar to the second method in that it softens the roving, which is also referred to as roving, and softens the above-mentioned gluing film, and then softens the yarn with the softener.

Through the above explanation, I hope that you will not have to worry about the situation of playing with polypropylene yarn, and you can easily ease it by using the above method.
