Problems solved by technology

[0005] From the current existing technology, most chitin polyester fibers are attached to textile fibers through post-treatment, but with daily use, washing, etc., the chitin on the fiber surface will gradually lose
At the same time, when chitin is added to polyester melt chips for spinning, due to the change of polyester fiber process and shape, the phenomenon of tripping is serious in the process of preparing polyester fibers, and there are many cases of rabbit heads, which are serious. It affects the unwinding performance of the winding drum, resulting in broken ends and hairs in the subsequent processing

Abstract

The invention provides a chitin polyester fiber. Raw materials for preparing the fiber include polyester chips, chitosan, a modifier and a regulator; and the mass ratio of the polyester chips to chitosan to the modifier to the regulator is (75-85):(3-5):(4-5.5):(1.5-2.3). The polyester chips has the water content of less than or equal to 0.2%, the acetaldehyde content of less than or equal to 1%,the acid value of max.35 Meq / kg and the inherent viscosity of 0.865+ / -0.015 dl / g; the chitin polyester fiber provided by the invention has the water retention rate of 18-20% and the dyeing degree of 92-95%; and the chitin polyester fiber has functions of permanent skin affinity, antibacterial property and mildew prevention. No spinder webs are generated in a process of preparing the chitin polyester fiber, so that the winding performance of a bobbin is improved, the web breaking and filament breaking caused in subsequent processing due to the addition of chitin fiber are avoided, and the quality of the fiber is improved.

Description

technical field [0001] The invention relates to a chitin polyester fiber and belongs to the field of fiber technology. Background technique [0002] As one of the three main fibers in synthetic fibers, polyester is widely used in clothing fabrics and other non-clothing fields because of its excellent physical and chemical properties. Since its inception, polyester products have also been used by downstream users as the main textile raw material for weaving various textiles due to their good drapability, high strength and crispness. With the globalization of the economy and the internationalization of the market, people's requirements for clothing are getting higher and higher. Not only must they be comfortable, but they must also be functional. It is necessary to continuously improve performance to meet weaving requirements. The polyester industry in my country has developed rapidly. The output of polyester fiber has grown from 5.165 million tons in early 2000 to 27 million ...
