Abstract

The present invention relates to a pinning process for a far infrared chinlon 6 FDY. The far infrared chinlon 6 FDY is prepared from raw materials comprising chinlon chips and additives by a process route comprising a screw extruder, a pre-filter, a static mixer, a metering pump, a spinning assembly, flow, side blowing, oil application, a spinning shaft, a first godet, a second godet, a third godet and winding. 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, in particular to a spinning process for producing nylon fibers 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. Among them, polycaprolactone amide fiber and polyhexamethylene adipamide fiber have the largest output and are the most widely used. 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...
