Problems solved by technology

However, due to the poor strength of the pure cotton spinning yarn used to produce this fabric, and the high weaving density, the warp and weft density are more than 100, and there are considerable difficulties in the weaving process. Therefore, very few manufacturers can produce it at present, and The quality of the high-count and high-density feather-proof cloth produced is poor, which leads to the production difficulty and processing quality of its subsequent processing procedures. The industry had a big impact

Abstract

The invention discloses a manufacturing method of high count and high density down-proof cloth. The cloth of the invention is made from a long-staple cotton combed yarn after procedures of warping, sizing, reeding, air-jet weaving, cloth inspecting, finishing, packing and stocking, etc. The sized yarn is made from mixed slurry of PVA and etherifying starch and sized by double-clip-double-nip and high temperature sizing; the weaving adopts the air-jet weaving and the ratio of a weft tension peak value and weft tension strength is controlled to be less than or equal to 55 percent. The invention is characterized by simple operation, easy control, high production efficiency and product quality, high cloth quality of produced products, smooth, even and clean cloth surface, soft and fine texture, erect and smooth hand feeling, special high moisture absorption and discharging performance, and the invention resembles to imitating the style of silk fabric, which is beneficial for improving downstream processing procedure and processing quality.

Description

technical field [0001] The invention relates to a production method of a textile fabric, in particular to a production method of a high-count and high-density feather-proof cloth. Background technique [0002] High-count and high-density feather-proof cloth is a textile fabric that is in short supply in the domestic and foreign markets. After printing and dyeing, the fabric has the characteristics of soft texture, smooth surface, uniform cloth surface, and clear lines. It is an ideal clothing fabric. . However, due to the poor strength of the pure cotton spinning yarn used to produce this fabric, and the high weaving density, the warp and weft density are more than 100, and there are considerable difficulties in the weaving process. Therefore, very few manufacturers can produce it at present, and The quality of the high-count and high-density feather-proof cloth produced is poor, which leads to the production difficulty and processing quality of its subsequent processing pr...
