Embodiment 1

[0027] A method for one-side dyeing of pure cotton woven fabrics. First, the woven fabrics are subjected to pretreatment, including gray cloth turning, singeing, desizing, scouring, bleaching, and mercerizing; Apply the color paste glue A to the woven fabric through the 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 to the woven fabric through the coating machine It is made by painting, high temperature hot air tentering, and falling cloth.

[0028] The formula of coloring glue A:

[0029] Sulfur dyes 2%

[0030] Reducing agent 4%

[0031] Thickener 2%

[0032] Water 92%

[0033] The sulfur dye described therein is Trisol ROT produced by Clariant, Switzerland; the reducing agent is D-glucose produced by Shanliang Taihang Pharmaceutical Factory or Xi'an Pharmaceutical Factory; the thickener is produced by Liaoning Dandong Star Fine Chemical Co., Ltd. FS...

Embodiment 2

[0042] A method for one-side dyeing of tencel woven fabrics, first, the woven fabrics are subjected to pretreatment, including gray cloth turning, singeing, desizing, scouring, bleaching, mercerizing, etc.; It is to apply the color paste glue A on the woven fabric through the coating machine, and then go through high-temperature hot air tentering, oxidation, soaping, water washing, drying, and falling cloth; then the color paste glue B is passed through the coating machine on the machine. It is made by painting on the fabric, stretching with high-temperature hot air, and dropping the cloth.

[0043] The formula of coloring glue A:

[0044] Sulfur dyes 7%

[0045] Glucose 7%

[0046] Thickener 3%

[0047] Water 83%

[0048] The sulfur dye described therein is Trisol ROT produced by Clariant, Switzerland; the reducing agent is D-glucose produced by Shanxi Taihang Pharmaceutical Factory or Xi'an Pharmaceutical Factory; the thickener is FS produced by Liaoning Dandong Star Fin...

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...
