Abstract

The invention discloses an antibacterial finish method for a blended cotton fabric. The antibacterial finish method comprises the following steps: (1) grinding sabina chinensis, extracting the sabina chinensis in ethanol aqueous solution after grinding, performing centrifugal separation after extracting, and concentrating the supernatant, thereby obtaining a sabina chinensis extract; (2) additionally taking green tangerine peel, drying and grinding the green tangerine peel, extracting the green tangerine peel in the ethanol aqueous solution, performing centrifugal separation after extracting, and concentrating the supernatant, thereby obtaining the green tangerine peel extract; (3) taking chitosan, nanometer titania, the sabina chinensis extract, the green tangerine peel extract and water according to the weight, dissolving the chitosan, nanometer titania, sabina chinensis extract and green tangerine peel extract by using water, and stirring to be uniform after dissolving; and (4) immersing a blended cotton fabric in the mixed solution, soaking, soaking twice and padding twice, and drying, thereby obtaining the antibacterial blended cotton fabric. The prepared blended cotton fabric has high antibacterial performance.

Description

technical field [0001] The invention belongs to the field of textile dyeing and finishing, and relates to an antibacterial finishing method for textile fabrics, in particular to an antibacterial finishing method for blended cotton fabrics. Background technique [0002] Spandex has excellent elasticity, and its strength is higher than that of latex silk, its linear density is also finer, and it is more resistant to chemical degradation. Spandex has good acid and alkali resistance, sweat resistance, sea water resistance, dry cleaning resistance and abrasion resistance. The ratio of spandex used in general clothes is relatively low. When used, a large number of other fibers such as cotton and polyester blends are added to minimize the luster. [0003] Polyester has the characteristics of high strength. The short fiber strength is 2.6-5.7cN / dtex, and the high-strength fiber is 5.6-8.0cN / dtex. And its hygroscopicity is low, and its wet strength is basically the same as the dr...
