Description
Technical Field
The invention belongs to the technical field of cotton and linen fabric processing, and particularly relates to a treatment process for improving the fluffing tendency of cotton and linen fabric in a clothes taking process.
Background
Along with the continuous development of science and technology, the anti-fluffing fabrics for textiles meeting different requirements of people come in a large number, and particularly, various anti-fluffing fabrics with special functions are developed rapidly to meet the requirements of consumers, so that the anti-fluffing fabrics play an increasingly important role in the daily life of people. Textile inevitably receives repeated friction in the use process, the two ends of the fiber in many fabrics are exposed to form fuzz, when the fuzz can not fall off quickly and continuously receives friction, the fuzz and the fuzz are formed into particles, so that the appearance of the fabrics is damaged, and the fabric is concerned by consumers. Factors influencing the degree of fuzzing and pilling of the fabric are various and comprise fiber performance, spinning mode and process conditions, yarn blending proportion and raw material collocation, weaving type, organizational structure, dyeing and finishing process, service conditions and the like.
At present, the woven bedding has good wear resistance and pilling resistance, and almost occupies the whole bedding market. However, the softness and skin-friendly property of the traditional woven fabric are inferior to those of the knitted fabric, and people pay more attention to the comfort performance of the traditional woven fabric as a textile which is in direct contact with the skin of a human body for a long time, so that knitted bedding is gradually developed in recent years. Knitted bedding products, while superior in comfort to traditional woven bedding products, have poor pilling resistance. The fluffing and pilling not only seriously affect the appearance of the bedding and shorten the service life, but also affect the skin-friendly performance of the bedding and the like. Therefore, how to overcome the characteristic that the fabric is easy to fluff and pill becomes an industrial problem which needs to be solved urgently.
