Problems solved by technology

[0004] Due to the very small single fiber fineness of ultra-fine fibers, problems such as broken ends and wool are prone to occur during the production process of spinning and texturing, resulting in unstable production quality and low yield, which makes the production capacity and application limited prospects
For example, due to the low denier air-covered yarn 2020 / 12 nylon elastic yarn with small denier, POY is prone to adverse phenomena such as large denier deviation and low breaking strength during the spinning process. In addition, in the elasticized false twist deformation, Also prone to decapitation and stiffness
[0005] Therefore, in view of the above-mentioned defects existing in the current prior art, it is necessary to carry out research to provide a solution to solve the defects existing in the prior art, and to avoid the breakage of the superfine denier coated wire during the production process. Head, hair and other problems, resulting in unstable production quality and low yield, which limits production capacity and application prospects

Abstract

An embodiment of the invention discloses a production method of nylon superfine fineness semi-dull air coated filaments. The production method includes steps: fusing and high-speed spinning; cross air blasting for cooling; oiling and bundling; winding; lead wire heating; cooling and false twisting, and drafting and wire stitching. A Hongyuan air coated yarn all-in-one machine is used for producing air coated yarns, fibers enter a drawing roller, spandexes are fed in a driven mode, and the drawing ratio ranges from 1.5 to 3.5; and Polyester Pre-Oriented Yarn (POY) filaments are fed in a driving mode, the drawing ratio ranges form 1.1 to 1.35, and the POY filaments are subjected to false twisting forming through 1-4-1 to 1-7-1 combined ceramic friction sheets, are subjected to doubling together with the spandexes and are subjected to cladding production, wire stitching, oiling and winding of an air network through the same Haibolin wire stitching machine. The production method of the nylon superfine fineness semi-dull air coated filaments through the air coated yarn all-in-one machine in a direct spinning method is formed through parameter improvement, problems of end breaking, filament breaking and the like are solved, the product production quality is led to be stable, and the yield is improved.

Description

technical field [0001] The invention belongs to the technical field of spinning, and in particular relates to a method for manufacturing nylon superfine fineness semi-dull air-covered yarn. Background technique [0002] Microfiber has extremely small linear density and high specific surface area, which makes the fabric have high coverage, soft hand feeling and comfortable wearing. As the fiber fineness decreases, the proportion of scattered light reflected by the fiber surface increases. This will make the apparent tone of the fabric darker and softer, and can be made into imitation silk, imitation peach skin, imitation suede, imitation wool and high-density products. At the same time, it can be used to make artificial leather, clean cloth, advanced air filter, dust mask, ski and water ski sportswear, swimsuit and other moisture-permeable and waterproof fabrics. Therefore, superfine fiber has become a hot textile raw material for various textile manufacturers at home and ab...
