Embodiment 1

[0021] Nylon 66 slices and additives are used as raw materials to prepare stretched twisted elastic yarns by POY-DTY process, wherein in the POY-DTY process, the process route of POY is: screw extruder → pre-filter → static mixer → Metering pump→spinning assembly→spinning→side blowing and oiling→passage→POY winding yarn; among them: melt spinning temperature: 275-280°C; side blowing conditions: wind speed 0.2-0.5 m / s, wind temperature 20 -30 ℃, relative humidity 60-75%; oiling rate 0.8-1.8%; spinning speed 3500-4500 m / min; among them, DTY production process route is: yarn guide → feeding roller → first heat Box→cooling plate→false twister→output roller→oiling device→DTY winding yarn; among them, the temperature of the first hot box is 160-175 ℃, the D / Y ratio is 1.2-1.8, and the draft ratio is 1.15 -1.30. Based on the weight of the nylon 66 chips, the additives include 0.2wt% calcium carbonate, 1.0wt% polyvinyl chloride, 0.25wt% alkylated monophenol, 1.0wt% titanium dioxide m...

Abstract

The invention relates to a far-infrared nylon 66 draw-twisting stretch yarn which is manufactured by taking nylon 66 slices and additives as raw materials and adopting a POY (pre-oriented yarn)-DTY (draw textured yarn) process. The far-infrared nylon 66 draw-twisting stretch yarn is simple and feasible in process, nylon fibers obtained by preparation are added with composite far-infrared particles, and the microencapsulation technology is combined, so that the far-infrared nylon fibers are good in durability.

Description

technical field [0001] The invention belongs to the field of spinning materials, and in particular relates to stretching and twisting elastic yarn of nylon 66 produced by slicing. Background technique [0002] At present, synthetic fibers generally include polyester (polyester), nylon (polyamide), polypropylene (polypropylene), spandex (polyurethane), acrylic (polyacrylonitrile) and the like. These fibers have different properties and thus different uses. [0003] 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. Among them, polycaprolactone amide fiber (Nylon6, nylon 6, nylon 66) and polyhexamethylene adipamide fiber ...
