Abstract

The invention discloses a dyeing process of cotton / aloe fiber blended yarns. The dyeing process comprises the following steps: (1) performing pretreatment: selecting raw materials: the cotton / aloe fiber blended yarns, and preparing a pretreatment liquid: 0.8 to 1.1 g / L of polyphenol oxidase, 0.5 to 0.8 g / L of phytase, 1 g / L of cellulase, 2 g / L of silk fibroin and 2.3 to 2.8 g / L of trimethylglycine, wherein the enzyme activity of the polyphenol oxidase is 350 u / g and the enzyme activity of the phytase and the cellulase is 500 u / g; the treatment parameters are as follows: 3 to 5% (owf), the time is 35 to 45 minutes and the temperature is 35 to 40 DEG C; (2) performing dyeing treatment: completely rinsing the pretreated cotton / aloe fiber blended yarns, drying, and performing one-bath one-step dyeing on aloe fiber knitted fabric by selecting reactive dye and by a dip dyeing method, wherein the specific dyeing process flows are as follows: wetting, dyeing, soaping, dehydrating and drying.

Description

technical field [0001] The invention relates to a dyeing process of cotton / aloe fiber blended yarn, which belongs to the technical field of textiles. Background technique [0002] Aloe fiber is a new type of fiber for skin care and health care. It is a functional cellulose fiber made by adding aloe vera liquid into the fiber during spinning. It is a high-tech green ecological environmental protection product. Aloe fiber has three excellent performances: skin care, health care, and treatment. [0003] Aloe vera is a perennial evergreen herb of Liliaceae. Its fresh leaves contain various active ingredients such as anthraquinones, sugars, amino acids, vitamins, etc. It has the functions of improving human immunity, anti-aging, and treating rheumatism and rheumatoid arthritis. Efficacy, at the same time has a good skin care effect. In recent years, Huzhou Zhuli Technology Co., Ltd. has made aloe viscose fiber by adding aloe stock solution to cellulose fiber spinning with cott...
