Abstract

The invention discloses a nylon fiber capable of autonomously generating far infrared light and a preparation method of the nylon fiber and belongs to the fields of nylon fibers and preparation methods thereof. According to the nylon fiber capable of autonomously generating far infrared light, provided by the invention, the nylon fiber capable of autonomously generating far infrared light is prepared by adding 0.6%-5% of far infrared nanopowder into nylon fiber chips, and the problem of single performance of a nylon fiber product in the prior art is solved, so that a healthcare function is additionally provided for the nylon fiber, and a medical gauze is capable of promoting wound healing and accelerating local blood microcirculation when the medical gauze prepared from the nylon fiber isused. According to the preparation method of the nylon fiber capable of autonomously generating far infrared light, provided by the invention, the far infrared nanopowder is added into the nylon fiberchips, and meanwhile, each process parameter under each process step is set, so that the nylon fiber capable of autonomously generating far infrared light can be industrially produced in batches, andthe whole production process is matured and controllable.

Description

technical field [0001] The invention relates to a nylon fiber and a preparation method thereof, in particular to a nylon fiber capable of autonomously generating far infrared rays and a preparation method thereof. Background technique [0002] The scientific name of nylon fiber is polyamide fiber, which was originally the trade name of polyhexamethylene adipamide produced by DuPont, which is commonly known as nylon 66 (Nylon 66). Polyamide fiber is the first commercialized synthetic fiber product of synthetic macromolecular polymer. ), thus opening the first page of synthetic fibers, which are still the representative of polyamide fibers to this day. [0003] Nylon fiber has high abrasion resistance, high breaking strength, good elongation at break, excellent elastic recovery rate, excellent fatigue resistance, good moisture absorption, good dyeability, high gloss, good anti-glare performance, good resistance to It has good heat resistance and chemical resistance, and is w...
