Abstract

The invention relates to a functional nylon-6 fiber and a preparation method thereof. The fiber comprises branched-chain nylon-6 functional master batches and conventional nylon-6 chips, wherein the branched-chain nylon-6 functional master batches account for 6-10% in weight percentage; the preparation method comprises the steps of firstly, preparing the branched-chain nylon-6 functional master batches with an in-situ polymerization method or a blending method; secondly, crystallizing and drying the branched-chain nylon-6 functional master batches and the conventional nylon-6 chips respectively, and mixing, and then performing vacuum drying to obtain blended chips; and finally, performing melt spinning to the blended chips. The using amount of functional additives is reduced properly under a condition that the functionality is improved or kept, the production cost is reduced and the fiber spinnability is improved.

Description

technical field [0001] The invention belongs to the field of functional nylon fibers, in particular to a functional nylon 6 fiber and a preparation method thereof. Background technique [0002] Nylon 6 fiber has a series of excellent properties, but also has disadvantages, such as low modulus, poor light and heat resistance, easy aging, and poor antistatic properties. With the improvement of living standards, people are not completely satisfied with the warmth effect brought by traditional fibers, and are more pursuing functionalization, refinement, health and quality. [0003] Compared with foreign developed countries, there are very few new nylon fiber products with independent intellectual property rights in my country at present, and fewer varieties are actually used for industrialization. Secondly, the price of nylon fiber is higher than that of polyester fiber, and fiber series products must be positioned at the high-end level. , in order to ensure the competitiveness ...
