Anti-breakage cuprammonium fabric and production method thereof

Abstract

The invention discloses an anti-breakage cuprammonium fabric. The anti-breakage cuprammonium fabric is formed by weavng warp yarns and weft yarns, wherein the warp yarns and the weft yarns have 5D to 150D cuprammonium filaments; and polyester yarns are arranged on the two sides of the fabric, and the number of the polyester yarns on one side is equal to that of the polyester yarns on the other side. The invention further discloses a production method of the anti-breakage cuprammonium fabric. The production method of the anti-breakage cuprammonium fabric comprises the following steps: 1), selecting the cuprammonium filaments as raw materials; 2), warping, wherein the difference between the thicknesses of the cuprammonium filaments wound at different positions of a warping shaft is not greater than 5mm after the warping, and corresponding polyester yarns are put on two sides of a warper; 3), sizing, wherein the speed of a yarn guiding roller is lower than that of a sizing roller in the sizing process; 4), performing warp rebeaming, wherein 8-12 polyester yarns on the two sides are divided into two equal groups and are put on the top during the warp rebeaming; 5), threading heddles and inserting a reed; and 6) weaving. Compared with the prior art, the invention has the advantages that the anti-breakage cuprammonium fabric is soft and smooth in touch feel, low in cost, accordant with requirements on greenness and environmental protection and low in end breakage rate; the overall strength of the anti-breakage cuprammonium fabric is higher than that of similar products; the anti-breakage cuprammonium fabric as a whole is liable to be broken; the production method of the anti-breakage cuprammonium fabric is simple in operation; by the production method, the problem that the cuprammonium fiber in the production process is easy to break is effectively solved; and the production difficulty of a pure cuprammonium fabric is reduced.

Description

technical field [0001] The invention relates to a textile fabric, in particular to a breakage-resistant cupro ammonia fabric, and also relates to a production method of the fabric. Background technique [0002] Cupro fiber is a kind of regenerated cellulose fiber. It is made by dissolving natural cellulose raw materials such as cotton linters in a concentrated ammonia solution of copper hydroxide or alkaline copper salt to prepare a spinning solution. Cellulose molecular chemicals are decomposed to regenerate cellulose, and the resulting hydrated cellulose is post-processed to obtain cupro ammonia fiber. The cross-section of cupro fiber is round, without sheath-core structure, and the monofilament produced is relatively thin, so the cupro fiber fabric is soft to the touch, soft in luster, has a real silk feel, and has good hygroscopicity. However, its wet strength is low and its wet elongation is high, so it is difficult to process the cupro fabric, and the cupro fiber is e...

Problems solved by technology

Due to the characteristics of low wet strength and high wet elongation of cupro fiber, the difficulty in the production process of pure cupro fabric lies in its weaving process, which is not mentioned in this patent application
