Abstract

The invention relates to chinlon 66 far-infrared PDY (Partially Drawn Yarn) filament fiber. The nylon-66 PDY filament is prepared according to a method in which high-speed spinning equipment is adopted, and chinlon 66 slices and additives are taken as raw materials. The method comprises the following steps: step 1, carrying out trickling, blowing laterally and oiling with a screw extruder, a pre-filter, a static mixer, a metering pump and a spinning component; and step 2, rolling with a channel, a first godet, a second godet and a third godet. The method is simple and feasible; as composite far-infrared particles are added into nylon fiber prepared according to the method, and the microcapsule technology is adopted, so that the far-infrared PDY filament fiber is good in durability.

Description

technical field [0001] The invention belongs to the field of spinning materials, and in particular relates to nylon fiber produced by slicing. Background technique [0002] Nylon fiber is the earliest synthetic fiber variety put into industrial production in the world. It is a kind of nylon synthesized by polycondensation reaction of aliphatic dibasic acid and diamine or aliphatic amino acid, and then melt-spun. The general term for synthetic fibers. Because they all contain amide bonds, they are collectively called nylon fibers. It is a kind of heterochain synthetic fiber. Nylon is not only the earliest industrialized synthetic fiber variety, but also has a variety of excellent properties, such as high strength, elasticity, and good wear and weather resistance, so it is welcomed by consumers, but with the improvement of people's living standards With continuous improvement, people's requirements for the diversity, comfort and functionality of clothing are becoming more ...
