Problems solved by technology

However, due to the torsion of cotton fibers during the growth period, the specific surface area decreases, resulting in weakened capillary effect, and the longitudinal surface is not like hemp fiber and bamboo fiber, there are grooves and cracks that can enhance the capillary effect of the fabric, thus affecting the fabric. Moisture conductivity of cotton fiber
Therefore, under the conditions of high temperature and high humidity in summer or in the case of a lot of sweating, it will expand due to moisture absorption, and its luck will decrease, so it will stick to the skin, and due to the expansion after moisture absorption, the pores between the fabrics will be blocked, thereby hindering It improves the heat and moisture exchange between the microclimate between the skin and clothing and the external environment, making people feel stuffy
And when the human body stops sweating, because the pure cotton fabric dehumidifies slowly, the moisture will squeeze the air inside the fabric, and the fabric's thermal insulation will decrease, and the human body will feel cold, so the comfort of the pure cotton fabric is not good at this time.

Abstract

The invention provides a polyamide 56 fiber as well as a preparation method and application thereof. The moisture regain of the polyamide 56 fiber is 3.8% or more. The polyamide 56 fiber provided by the invention can effectively improve the moisture conductivity and moisture permeability of a natural fiber when blended with the natural fiber, so that a fabric can quickly absorb the moisture from the surface of the skin and quickly transfer the moisture to the outer surface of the fabric for evaporation, the interior of the fabric keeps dry, and the comfort of the human body is significantly enhanced.

Description

technical field [0001] The invention relates to fiber technology, in particular to a polyamide 56 fiber and its preparation method and application, belonging to the field of textile technology. Background technique [0002] Polyamide fiber is one of the first synthetic fibers put into industrial production in the world, and its output ranks second among synthetic fibers. It is made of polyamide by melt spinning. The main varieties of existing polyamide fibers are PA6, PA66, PA4, PA7, PA8, PA9, PA11, PA12, PA610, PA1010, PA6T, MXD6, PACM-12 (alicyclic polyamide fiber), PA612. The spinning process is relatively mature, and some have been industrialized. [0003] Polyamide fibers can be used to produce fabrics. For fabrics, there are basically two main types of yarns as raw materials, namely continuous filament yarns and yarns made from staple fibers. At present, the polyamide fibers on the market are mainly long fibers, and the number of short fibers is relatively small. P...
