Chinlon high-speed spinning technology

Abstract

The invention relates to a chinlon high-speed spinning technology which comprises the following steps of using chinlon slicing as raw materials, and carrying out fusion, spinning, circular air blowing, drafting, heat shaping, oiling, mesh forming and winding in sequence. The chinlon high-speed spinning technology differs from the prior art, and has the advantages that the circular air blowing is adopted to replace side air blowing to enable fusion bodies to be cooled evenly in all directions, the phenomenon that the inner layer and the outer layer of a yarn bundle are uneven in cooling is avoided effectively, yarn unevenness of the yarn bundle is reduced, the shaping quality of the yarn bundle is improved greatly, cooling time is shortened at the same time, and energy consumption needed by cooling is reduced; the oiling is changed to be carried out after the heat shaping, due to the fact that the moisture contained in the yarn bundle will be evaporated under heating when the heat shaping is carried out, the oiling can be carried out on the yarn bundle directly after the yarn bundle comes out of the heat shaping procedure, drying equipment, drying time and energy consumption needed by drying are eliminated, a production line is simplified greatly, production efficiency is improved, production energy consumption is reduced, and meanwhile the whole production process is made to be smoother.

Description

Technical field [0001] The invention relates to the technical field of textiles, in particular to a nylon high-speed spinning process. Background technique [0002] Nylon fiber has excellent dyeability, high strength, good gloss, good drape, good moisture absorption, etc., so it has been widely used in clothing, decoration and industry and other fields, including nylon silk that can be used as clothing fabrics Textiles, taffeta, umbrella silk, stretch fabrics, warp knitted fabrics and knitted garments, etc.; and stockings and pantyhose for the hosiery industry, especially for women; webbing (such as elastic belts, hook and loop belts, velvet belts, Hemming belts, trademark belts, luggage belts); industrial yarns such as fishing lines and cords; decorative yarns such as curtains, shower curtains, and carpets. The proportion of textiles and garments, household decorations and industrial yarns is roughly 50:26:24. [0003] At present, nylon fiber is generally produced by high-speed ...

AI Technical Summary

Problems solved by technology

[0006] 1. The effect of side blowing is not ideal, and it is easy to cause uneven cooling of the inner and outer layers of the tow or large unevenness, and the cooling time is long and energy consumption is high;

[0007] 2. Oiling is carried out after side blowing. Since the humidity of side blowing is generally above 70%, even as high as 95%, the tow after side blowing will contain a lot of water. At this time, the water must be removed before oiling. The process of removing moisture (usually using heat to vaporize moisture) will lead to increased equipment investment, extended production lines, increased production energy consumption, reduced production efficiency, and sometimes causes interruptions in the production process, especially not suitable for ultra-fine pellets.
