Problems solved by technology

Although the new process improves the utilization rate of dyestuffs, since the viscose / lyocell / cotton fibers are implanted with cationic groups, the viscose / lyocell / cotton fibers are positively charged, and in the process of washing the cloth , negatively charged dye molecules are very easy to be compatible with the white ground of viscose / lyocell / cotton fibers, resulting in sticky stains on the white ground. Therefore, it is also necessary to develop an anti-staining treatment process to prevent it from sticking to stains

Abstract

The invention provides a printing process of a viscose / lyocell / cotton blended fabric. Desizing is conducted on a gray fabric formed by conducting blending on three types of fibers, namely viscose, lyocell and cotton, then scouring and bleaching and drying are conducted, then padding with modification liquid is conducted, water washing, neutralization, water washing and drying are sequentially conducted after cold batching, printing is conducted with reactive dye, and then drying, primary ageing, staining prevention treatment, secondary ageing, water washing and drying are sequentially conducted; and a staining prevention agent used for staining prevention treatment is selected from an aqueous solution of one or more of sodium benzenesulfonate, sodium p-toluenesulfonate, butylnaphthalenesulfonic acid sodium salt, alkybenzene sulfonate, alpha-olefine sulfonate, alkyl sulfonate, succinic ester sulphonate, petroleum sulfonate, ligninsulfonate and alkyl glycerol ether sulfonate. The fabricprinted through the printing process is high in dye utilization rate, deeper in color and slight in water color fading, the production cost is saved, the treatment pressure of printing and dyeing wastewater is reduced, and good anti-staining performance is achieved.

Description

technical field [0001] The invention belongs to the technical field of textile printing, and in particular relates to a printing process of viscose / lyocell / cotton blended fabrics. Background technique [0002] Although the research and development of synthetic fibers has become a trend that cannot be ignored in today's world, cellulose fibers are still the most important textile raw materials relying on their excellent natural comfort and unique physical and chemical properties. Due to the integration of the advantages of different fibers, the multi-fiber component cellulose fiber blended fabric has the characteristics of complementary advantages, which is the future development trend. However, due to the different aggregation structures of different cellulose fibers, the dyeing performance of reactive dyes on different fibers varies greatly. For example, the crystallinity of viscose fiber is lower than that of lyocell fiber and cotton fiber, and the content of amorphous re...
