Abstract

The invention relates to an anti-ultraviolet nylon fiber spinning process. The anti-ultraviolet nylon fiber spinning process includes steps of using nylon chips and additives as raw materials on high-speed spinning equipment and adopting a process route of a screw extruder, a pre-filter, a static mixer, a metering pump, a spinning component, trickling, side blowing, oiling, a passage, a first fiber guide roll, a second fiber guide roll, a third fiber guide roll and winding. The process method is simple and feasible, an ultraviolet screening agent and an ultraviolet absorbing agent are added into prepared nylon fibers, and the microcapsulary is further adopted to enable lasting effectiveness of the anti-ultraviolet performance of the fibers. In addition, the process is applicable to preparation of 20D-70D nylon filaments, and corresponding dull or semi-dull products can be obtained by adding delustrant for preparation.

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] 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 6) and polyhexamethylene adipamide fiber (Nylon66, nylon 66, nylon...
