Abstract

The invention relates to a production technology of copper ammonia wool blended fabric. The production technology is characterized by comprising the processing steps of (1), blending copper ammonia fiber and wool fiber to obtain a copper ammonia blended gray fabric, wherein the mass ratio of the copper ammonia fiber and the wool fiber is (40-60):(40-60); (2), washing with water: washing the copper ammonia blended gray fabric in a water washer with the bath ratio of 1: (30-50), adding neutral cleaning agent, wherein the dosage of the cleaning agent is 3-5g per liter of water and the water temperature is 60 DEG C to 65 DEG C; (3), scouring, dewatering and drying in a cylinder: performing scouring treatment to the copper ammonia blended gray fabric washed with water in a dye vat, wherein the weight ratio of the copper ammonia blended gray fabric and the water is 1:(5-12), the concentration of scouring agent is 1-5g / L, and the concentration of sodium carbonate is 1-2g / L, the processing time is 0.5 hour to 1 hour and the scouring temperature is 70 DEG C to 85 DEG C; (4), dyeing, and (5), sizing. The copper ammonia wool blended fabric is obtained by blending the copper ammonia fiber and the wool fiber according to the production technology, the antimicrobial property of the copper ammonia fiber is not likely to be destroyed, and meanwhile the copper ammonia wool blended fabric is more comfortable in wearing.

Description

technical field [0001] The invention relates to a fabric, in particular to an antibacterial cuproammonia 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 bleach and hydrogen peroxide, the fa...
