Abstract

Belonging to the application technology field of yarn dyed fabric dyeing and finishing in the textile industry, the invention provides a dyeing and finishing method for a durable press bombasine yarn dyed fabric, and aims to solve the technical problems of easy fiber damage, undesirable antiwrinkling effect and poor washfastness, easy generation of formaldehyde residue and other ecological pollution. The method provided in the invention combines a chemical technique and a biological enzyme technique to carry out scouring and bleaching and dyeing on a bombazine fabric, that is to say, caustic soda, cellulose and catalase are taken for cotton fiber scouring and bleaching, soda ash, protease and lipase are taken for raw silk degumming and dyeing, and an active dye and laccase are employed to perform bombazine fiber dyeing and aftertreatment. Meanwhile, formaldehyde-free antiwrinkling resin is employed to perform liquid ammonia moist crosslinking on the fabric so as to improve the wrinkle resilience of the fabric. By applying the method provided in the invention to perform dyeing and finishing on the bombasine yarn dyed fabric, the fabric has a smooth surface and soft handfeel, also, the chroma of a dyeing waste liquid is reduced. When high antiwrinkling performance is acquired, the fabric strength is less reduced. The treatment process is safe and environment-friendly, thus being in line with the processing requirements of ecological textiles.

Description

Technical field [0001] The invention relates to a dyeing and finishing method for durable pressed silk-cotton fabrics, which belongs to the application technical field of dyeing and finishing of colored fabrics in the textile industry. Background technique [0002] Cotton fiber is a kind of natural cellulose fiber, which has many characteristics such as soft hand, light and alkali resistance and excellent dyeing performance. Silk fiber is a kind of natural protein fiber, which not only has fine appearance, soft luster and smooth hand feeling, but also has good antibacterial properties. The interweaving of silk and cotton fibers can enhance the moisture absorption and warmth retention of silk products, improve the feel and luster of pure cotton products, improve the health function of yarn-dyed products, and increase the added value of fiber products. [0003] In addition to cellulose macromolecules, cotton fibers also contain non-fiber symbiotics such as pectin, cotton wax and nat...
