Cellulose fiber fabric printing process

Abstract

The invention discloses a cellulose fiber fabric printing process. The cellulose fiber fabric printing process comprises the following steps that 1, cationic modification of cellulose fiber fabric iscarried out; 2, bleaching, acid neutralization and drying are carried out; 3, reactive dye printing is carried out; 4, aging, washing, soaping and finished product shaping are carried out; cationic modification is cold reactor modification or impregnation modification; the amount of a cationic modifier in cold reactor modification is 20-50g/L, and the amount of a cationic modifier in impregnationmodification is 10-30g/L; and in reactive dye printing, catalysts such as triethylene diamine, niacin, trimethylamine, and pyridine need to be added. According to the cellulose fiber fabric printing process, moderate cationic modification is carried out on the cellulose fiber fabric, and meanwhile, the catalysts are assed during printing, so that in the process of ageing and color-fixing, cation adsorption and catalysis and color-fixing are performed simultaneously, a synergistic effect is achieved, the high color-fixing rate of the reactive dye is ensured, the difficulty of washing after printing is reduced, the problem of white background staining is effectively solved, and the amount of water used for printing washing is reduced.

Description

technical field [0001] The invention belongs to the technical field of textile printing, and in particular relates to a cellulose fiber fabric printing process. Background technique [0002] Textile printing technology has a long history. In ancient times, there were techniques such as tie-dyeing and batik to present various complex patterns on textiles. [0003] With the beginning of the modern industrial revolution, mass-produced flat screen printing and rotary screen printing appeared. Especially since the 21st century, with the rapid development of electronic information technology, new technologies such as wet transfer printing and digital inkjet printing have emerged continuously. Make the printing products present a more three-dimensional and realistic effect. [0004] However, in the process of applying the above-mentioned printing process to cellulose fiber fabrics, there is a problem that the color fixation rate of reactive dyes is not high, which will not only ca...

Problems solved by technology

[0004] However, in the process of applying the above-mentioned printing process to cellulose fiber fabrics, there is a problem that the color fixation rate of reactive dyes is not high, which will not only cause the pattern color to be light and not bright enough, but also lead to high chroma of printing wastewater and difficult treatment, etc. question

[0005] Cationic modification of cellulose fiber fabrics is the most common method to solve the problem of the fixation rate of reactive dyes. It is widely used in the technical field of cellulose fiber fabric dyeing. There is an obvious problem of white background staining
