Problems solved by technology

At present, functional fibers have been mostly used in the specifications of polyester production, but the development of nylon functional products is far behind the level of domestic polyester factories. Domestic nylon chemical fiber production or development of nylon functional products The manufacturers of nylon are not common enough, and most of them focus on the production of conventional varieties. In fact, the hydrophilicity of nylon, the abrasion resistance of fibers, and the dyeing fastness are better than polyester, and it is more suitable for use in close-fitting clothing for the human body. Due to this characteristic, the functionality of nylon filaments used in body-fitting fabrics has been more and more developed and researched, hoping to closely combine the long-term health care of the human body and the application of environmentally friendly materials.

Abstract

An embodiment of the invention discloses a production method of functional nylon air cleaning negative ion air coated filaments. The production method includes steps: (a) fusing and high-speed spinning; (b) cross air blasting for cooling; (c) oiling and bundling; (d) winding; (e) lead wire heating; (f) cooling and false twisting and (g) drafting and wire stitching, and finally the functional nylon air cleaning negative ion air coated filaments are obtained. The production method of the functional nylon air cleaning negative ion air coated filaments is formed through appropriate negative ion master batch material selection, a filling machine with excellent performance and adjustment of spinning temperature, cooling conditions, spinning speed, oiling rate, winding speed and the like, and the produced functional nylon air cleaning negative ion air coated filaments can well release negative ions so as to improve the environment and meanwhile have good quality level stability.

Description

technical field [0001] The invention belongs to the technical field of spinning, and in particular relates to a method for manufacturing nylon functional air-cleaning negative ion air-coated yarn. Background technique [0002] In purifying air, the molecular formula of negative air ions is O2-(H2O)n, or OH-(H2O)n or CO4-(H2O)n. The negative air ions with environmental protection function mainly refer to the first two small molecular negative ions. Negative air ions can restore active oxygen (oxygen free radicals) produced by atmospheric pollutants, nitrogen oxides, cigarettes, etc., and reduce the harm of excessive active oxygen to the human body; neutralize positively charged air dust and settle without charge, making The air is purified, and negative ions can also purify odors. [0003] With the development of industry and commerce, the odor emitted from factories, the exhaust gas emitted by automobiles are increasing, and the second-hand smoke exhaled by people's daily s...
