Abstract

The invention discloses pure-copper-ammonia jacquard fabric consisting of warps and wefts in a woven manner. Both the warps and the wefts are 75-150D (denier) pure-copper-ammonia filaments. The warp-wise density ranges from 429 / 10cm to 600 / 10cm, the weft-wise density ranges from 310 / 10cm to 429 / 10cm. Meanwhile, the invention further discloses a production method of the pure-copper-ammonia jacquard fabric. The production method includes the following steps of firstly, selecting the copper ammonia filaments as raw materials; secondly, beaming until the thickness of copper ammonia filaments wound on a beaming shaft is not more than 5mm; thirdly, pulping and keeping the speed of a yarn guide roll of a pulping machine lower than the speed of a pulping roll during pulping; fourthly, shaft integrating; fifthly, threading harness wires and inserting reed; and sixthly, weaving on the machine. Compared with the prior art, the pure-copper-ammonia jacquard fabric is soft and smooth in touch, low in cost and breakage and higher in integral strength than the like products and meets the requirement of environment friendliness. The production method is simple to operate, effectively solves the problem of easiness in copper ammonia fibers during production and reduces production difficulty of the pure-copper-ammonia jacquard fabric.

Description

technical field [0001] The invention relates to a textile fabric, in particular to a pure copper ammonia jacquard 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 easy ...
