Abstract

The present invention relates to a far infrared DTY high-elastic filament for hosiery. The far infrared DTY high-elastic filament is prepared from raw materials containing chinlon 66 chips and additives by a POY-DTY process. The process provided by the invention is simple and practical; and the prepared fiber nylon is added with composite far infrared particles, and combined with micro capsule technology to gain good durability.

Description

technical field [0001] The invention belongs to the field of spinning materials, and in particular relates to a DTY elastic yarn for producing nylon 66 hosiery 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 (nylon 6...
