Abstract

The invention relates to a production method of copper ammonia blend fabric. The production method of copper ammonia blend fabric is characterized by including the following art steps: (1) blending copper ammonia fibers, spandex fibers and cotton fibers to obtain copper ammonia blending gray fabric, wherein mass ratio of spandex fibers, cotton fibers and cotton fibers is 40-60 to 3-10 to 30-57; (2) washing: washing the copper ammonia blend raw fabric in a water washer with a bath ratio of 1 to 30-50 and adding neutral cleaning agents with a dosage of 3 to 5 grams per liter water and the temperature is 60 to 65 DEG C; (3) refining: sinking the copper ammonia blend raw fabric which is washed by water in the water with a bate rate of 1 to 25-30, adding 10 to 20 grams sodium hydroxide per liter, and processing 0.5 to 1 hour with a refining temperature of 65 to 70 DEG C; (4) dyeing; (5) rinsing, drying and obtaining the copper ammonia blend fabric. The production method of copper ammonia blend fabric is manufactured by copper ammonia fibers, spandex fibers and cotton fibers, does not damage antibiosis performance and meanwhile possesses good comfort.

Description

technical field [0001] The invention relates to a fabric, in particular to a method for producing a cupro-ammonia blended fabric, and 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 p...
