Single-face dyeing method for woven fabric

Abstract

The invention discloses a single-side dyeing method of woven fabrics, which belongs to the new technical field of textile printing and dyeing. A method for single-side dyeing of woven fabrics, firstly pre-treating woven fabrics such as pure cotton, tencel, and elastic fabrics, including gray cloth turning over, singeing, desizing, scouring, bleaching, mercerizing, etc.; secondly, full-width single-side dyeing, One-side dyeing of woven fabrics is to apply the color paste glue A to the woven fabric through a coating machine, and then go through high-temperature hot air tentering, oxidation, soaping, water washing, drying, and falling cloth; then apply the color paste glue B Coloring on woven fabrics, high temperature hot air tentering, and falling cloth through a coating machine. This technology realizes the fashion of denim clothing, casual clothing and children's clothing, and has obvious ecological functions; it also solves the problem that the fabric can be dyed on one side with sulfur dyes and paints on the coating and setting machine. Technical problems; at the same time, it saves water, steam, and electricity compared with the conventional processes of vat and reactive dyes, and reduces a large amount of dyeing sewage discharge. The side of the single-side dyed fabric that is in contact with the human skin does not contain any dyes, chemicals, and additives. It is ecological and environmentally friendly. It is an ideal fabric for denim, casual wear and children's wear.

Description

technical field [0001] The application belongs to the new technology field of textile printing and dyeing, and relates to a method for single-sided dyeing of woven fabrics on a coating and setting machine using coloring technology and new auxiliary agents. technical background [0002] In the past, sulfur dyes and coatings can only be dyed on both sides on a continuous pad dyeing machine, and coatings can be dyed on both sides on a hot air primer and baking machine. The conventional dyeing process is as follows: [0003] Sulfur dyes: After padding dyeing solution, steam reduction, water washing and oxidation, soaping, hot washing, water washing and drying. [0004] Coating: After padding, drying, baking, stenter setting, and falling cloth. [0005] The problems existing in the prior art are: neither pad dyeing nor exhaust dyeing can be dyed on one side; the existing yarn-dyed denim is monotonous in color, lacks the colors such as crimson, dark green, and dark coffee that c...

Problems solved by technology

[0005] The problems existing in the prior art are: neither pad dyeing nor exhaust dyeing can be dyed on one side; the existing yarn-dyed denim is monotonous in color, lacks the colors such as crimson, dark green, and dark coffee that consumers like, and the clothing is in contact with the human body. Some parts have dyes; it is impossible to produce one-sided dyeing of woven fabrics on pad dyeing machines and exhaust dyeing equipment
