Single-face dyeing method for woven fabric

Abstract

A single-side dyeing method of woven fabrics belongs to the novel technical field of textile printing and dyeing. The single-side dyeing method of woven fabrics includes three steps; firstly, pure cotton, tencel and an elastic woven fabric are preprocessed, including the turnover sewing of greige cloth, singeing, desizing, boiling-off, bleaching, mercerization, etc., secondly, the full-width single-side dying of the woven fabric is to coat color sizing A on the woven fabric by a coating machine, and then high-temperature hot-air stentering, oxygenation, soaping, water washing, drying and cropping are carried out; finally, color sizing B is coated on the woven fabric by the coating machine, and high-temperature hot-air stentering and cropping are carried out. The technology realizes the fashion of the fabrics of jeans, leisure clothes and children dresses and has obvious ecological function; the technology also resolves the technical problem that a coating-shaping combination machine can carry out the single-side dyeing of fabrics by using sulfide colours, paints, etc., meanwhile, compared with the conventional techniques of vat dye, reactive dye, etc., the technology saves water, gas and electricity and reduces the discharge of a great deal of dyeing sewage. The side of the single-side dyed fabric, which touches the skin of the body, does not contain dyestuff and auxiliaries, thus having the characteristics of ecological and environmental protection.

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
