Background
In the wearing process of the fabric after being made into the clothing, the phenomenon of pilling is often caused by the friction of the fabric and the outside, the appearance and the service performance of the clothing are affected, and the anti-pilling is increasingly brought into the attention of textile, dyeing and finishing, clothing production factories and consumers in recent years along with the improvement of the living standard of people and the standard of European and American textiles, and the requirements on the anti-pilling are also higher.
Fuzzing and pilling are closely related to the weaving method of the fabric, the fabric structure, the spinning process of the yarn, and the like. The mechanism of pilling generated by different fibers is different, natural fibers such as wool fibers mainly exist in scale layers on the surfaces of wool, and the fibers continuously slide outwards and ball up in the processing and later taking processes due to the directional friction effect, so that the pilling is caused; synthetic fibers such as polyester fibers have smooth surfaces, good fiber breaking strength, low hygroscopicity and easiness in generating static electricity, so that the tail ends of the fibers easily slip out and are entangled together in the processing and taking processes, and fuzzing and pilling phenomena are extremely easy to generate. In order to be able to prevent pilling of the fabric or fibre, it is necessary to carry out a finishing process after dyeing. The current application is widely to carry out after finishing with anti-pilling finishing agents.
