Background
The fuzzing fabric has an appearance style, soft and comfortable hand feeling and the like which are incomparable with those of the traditional fabric, and becomes one of the main stream fabrics in autumn and winter which are rapidly developed in the world. The fuzzing fabric is formed by grinding or grabbing part of fibers of yarns on the surface of the fabric or yarns inside the fabric through a certain physical and mechanical means, so that a compact structure formed in the spinning or weaving process is damaged, and the surface fuzzing feeling with different lengths is realized. The common problem of the fabrics in the use process is that the pilling and the hair falling phenomena are serious, and the quality requirements of consumers on products cannot be met. With the continuous improvement of consumer experience, complaints and dissatisfaction of the problem become increasingly important technical pain points which plague the industry.
At present, the related technologies for solving the problems of pilling and hair falling of the fluffing fabric are fewer, and an effective solution is lacking in the market. Most of production enterprises adopt means of optimizing roughening, picking and the like, but the effect is very little. In the aspect of post-treatment, enterprises adopt anti-pilling products to treat, so that the pilling phenomenon is improved, but the sense of hand and the style of fabric are generally greatly influenced; the hair-falling phenomenon is improved to a certain extent, but the effect is greatly different from the expected effect, the problem of continuous hair-falling cannot be solved, and particularly the problem of continuous hair-falling after washing is very serious.

Detailed Description
Analyzing root causes of fuzzing, pilling and fuzzing of the fuzzing fabric: the fuzzing process has a certain degree of damage to the fibers, so that part of the fibers are shortened, cohesion force, strength and the like are lowered, part of the short fibers are carded out, part of the short fibers or damaged fibers are adhered to the surface or the inside of the yarns, and part of the fibers are separated from the main fabric in the use process, so that continuous fuzzing and dehairing phenomena are generated; meanwhile, a part of fibers are damaged and not broken, the cohesion force is reduced, the part of fibers are broken in the wearing process and are not separated from the yarn and the fabric main body, and fiber balls are formed through repeated friction, so that the appearance is affected, and the wearing comfort is reduced.
Through the analysis, in order to solve the problems of fuzzing, pilling and hair falling of the fuzzing fabric, the invention is characterized in that: after the knitting fabric mainly comprising polyester is subjected to fuzzing or roughening processing, a multi-branched polymer treating agent with certain surface activity is introduced by a post-treatment method, so that loose fibers cannot be easily stripped from original main yarns or fabrics even if the fuzzing fabric is rubbed or washed by external force in the later use process, and the problems of fuzzing and pilling are continuously improved. The post-treatment is mainly divided into three steps, firstly, as ions are not arranged on the molecular structure of the terylene, the molecular structure consistency is good, and the softening effect of the terylene is improved through grafting modification, thereby achieving the purpose of anti-pilling. The second step of treatment improves the problem of hair loss and simultaneously generally brings new problem of harder hand feeling. Through the treatment of the first step and the third step, the hand feeling problem brought by the second step is improved, and the anti-pilling and anti-falling effects are increased.
For the test method and standard of the hair loss judgment, no unified standard exists in the textile industry at present, and the test and evaluation method adopts a net easy test method KLTM001 of the hair loss performance of a nap textile product, which is applicable to knitted underwear.
