Abstract

The invention relates to a production technology of copper ammonia, linen and cotton blended fabric. The production technology is characterized by comprising the processing steps of (1), blending copper ammonia fiber, linen fiber and cotton fiber to obtain a copper ammonia blended gray fabric, wherein the mass ratio of the copper ammonia fiber, the linen fiber and the cotton fiber is (40-60):(15-30):(25-30); (2), washing with water: washing the copper ammonia blended gray fabric in a water washer; (3), scouring: immersing the copper ammonia blended gray fabric washed with water into a scouring solution with the bath ratio of 1:(20-25), wherein the components of the scouring solution are as follows: 30-35g / L of sodium hydroxide, 1-1.5g / L of scouring agent and the balance of water, the scouring time is 0.5 hour to 1 hour and the scouring temperature is 75 DEG C to 80 DEG C; (4), dyeing, and (5), rinsing and drying, so as to finally obtain the copper ammonia, linen and cotton blended fabric. The copper ammonia, linen and cotton blended fabric is obtained by blending copper ammonia fiber, linen fiber and cotton fiber; the antimicrobial property of the copper ammonia fiber is not likely to be destroyed, and meanwhile the copper ammonia, linen and cotton blended fabric is more comfortable in wearing.

Description

technical field [0001] The invention relates to a fabric, in particular to a production process of cuproammonia, hemp and cotton blended fabric, which belongs to the technical field of textiles and garments. 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 compounds are decomposed to regenerate cellulose, and the resulting hydrated cellulose can be post-processed to obtain cupro ammonia fiber. The cross-section of cupro ammonia fiber is round, without sheath-core structure, the fiber can withstand a high degree of elongation, and the monofilament produced is relatively thin, so the fabric feels soft, soft and lustrous, with a real silk feel. [0003] Due to the poor resistance of cupro fiber to oxidizing agents such as chlorine blea...
