Abstract

The present invention relates to a spinning process for an antistatic and antibacterial nylon 6DTY high elastic filament, which is prepared from raw materials comprising nylon 6 chips and additives by a POY-DTY process. The prepared DTY high elastic filament has antistatic and antibacterial function and good stability, and can meet different requirements of post-weaving finishing.

Description

technical field [0001] The invention belongs to the field of spinning materials, in particular to a DTY fiber spinning process for producing nylon 6 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. But at present generally take fabric, because its fiber is thicker, feel rough, softness is poor, air permeability is poor, water absorption is poor, easy to pilling. With the improvement of people's living standards, the requirements for textiles are getting higher and higher. [0003] Polyamide fiber is the earliest synthetic fiber variety put into industrial production in the world. It is made of polyamide synthesized by polycondensation reaction of aliphatic dibasic acid and diamine or aliphatic amino acid, and then melt-spun. A gener...
