Embodiment Construction

[0013] A method for manufacturing a cupro fabric, comprising the steps of obtaining a gray fabric by weaving and dyeing and finishing the gray fabric to obtain a cupro ammonia fabric, wherein,

[0014] Weaving: use 75D / 45F cupro fibers as warps and 75D / 54F cupro fibers as wefts, and sequentially go through the steps of warping, sizing, paralleling and weaving to obtain gray cloth, and the density of the gray cloth is 60*40 pieces / cm;

[0015] Dyeing and finishing: it includes the following steps in turn:

[0016] (1) Water washing: Put the gray cloth into the jigger for cleaning, and add cleaning agent, the jigger rolls are washed in front and back, and the overflow water flows out of the cloth. Among them, the amount of cleaning agent added is about 4g per liter of water, and the water temperature Keep it at around 61°C;

[0017] (2), scouring: soak the cloth in water with industrial soft water and circulate with the water flow, then add a sodium hydroxide solution with a ma...

Abstract

The invention relates to a manufacturing method of a cuprammonia fabric. The method comprises the steps of weaving and dyeing and finishing, wherein the step of dyeing and finishing sequentially comprises the substeps of 1 washing, 2 refining and 3 dyeing, wherein after a fabric is completely fed into a dyeing machine, a softening agent is added for rotation for 5-10 min, a dispersing agent and aleveling agent are added, dye is slowly added after rotation is performed for 5-10 min, after the dye is completely fed, the temperature begins to be increased to 70-90 DEG C at the speed of 0.6-1.0 DEG C / min, the temperature is kept constant for 8-12 min, and then the temperature is increased to 110-115 DEG C at the speed of 0.6-1.0 DEG C / min; the temperature is kept constant for 8-12 min, and then the temperature is increased to 120-125 DEG C at the speed of 1-1.1 DEG C / min; the temperature is kept constant for 30-45 min, and finally the temperature is decreased to 60 DEG C or below at the speed of 1.2-1.3 DEG C / min to drain bath solution, washing is performed, the fabric is discharged. The method is simple in technology, low in cost and capable of successfully producing the cuprammoniafabric, the obtained cuprammonia fabric has the good characteristics of copper ammonia fiber, and therefore the fabric is good in wearability and good in hygroscopicity, has the drapability and conforms to the environment-friendly dress fashion.

Description

technical field [0001] The invention relates to a method for manufacturing cloth, in particular to a method for manufacturing cupro ammonia fabric. Background technique [0002] Cuprammonuium fiber (Cuprammonuium) is a kind of regenerated cellulose fiber. It dissolves natural cellulose raw materials such as cotton linters in a concentrated ammonia solution of copper hydroxide or alkaline copper salt, and prepares a spinning solution. The molecular chemical of cupro ammonia cellulose decomposes and regenerates cellulose, and the resulting hydrated cellulose is post-processed to obtain cupro ammonia fiber. The cross-section of the cupro ammonia fiber is circular, without sheath-core structure, the fiber can withstand high temperature stretching, and the obtained monofilament is relatively thin, generally below 1.2 denier, up to 0.4 denier. Therefore, cupro ammonia fiber fabric has soft hand feeling, soft luster, real silk feeling, and fast moisture absorption, but its wet str...
