Problems solved by technology

[0002] Cotton-viscose-elastic interwoven fabric is fluffy, crisp, elastic, moisture-wicking, comfortable and close-fitting, and can meet the requirements of high-end fabrics. The difference in properties between cotton and viscose fibers in the actual production process makes the pre-treatment and dyeing and finishing processes more complicated, especially It is difficult to dye, the dark color is not full, the depth is not enough, and the technical requirements are high; during the weaving process of cotton viscoelastic fabric, there is a large residual stress inside the gray fabric, which will cause the fabric structure to deform. Problems such as creases and stripes are prone to occur during the dyeing process of fabrics

Abstract

The invention belongs to the technical field of textile printing and dyeing, and in particular relates to a dyeing and finishing technology for a cotton / viscose ammonia multi-fiber stretch fabric employing bio-enzyme low-temperature treatment. The dyeing and finishing technology comprises a pretreatment technology, a dyeing technology and a post-finishing technology. According to the printing and dyeing method for a cotton / viscose stretch fabric, room-temperature stacked desizing is carried out by a biologic desizing enzyme; and an efficient refining agent is selected, so that various pretreatment indexes are effectively improved; soft and fluffy hand feeling of the cotton / viscose stretch fabric is achieved; energy conservation and emission reduction are achieved through low-temperature desizing; potential drapes in the fabric processing process are eliminated; and smooth production of the dyeing procedure is facilitated. A light-colored fabric is dyed from pad dyeing, and a dark fabric is subjected to cold pad-batch dyeing, so that an improvement of various color fastness indexes is met; dyeing process parameters are optimized; and uniform and full dying material quality is obtained. A softening agent is preferably adopted in fabric post-finishing, so that the hydrophilicity of the fabric is achieved; and the wearing comfort of the fabric is achieved.
