Abstract
The invention relates to a preparation process for a window decoration and particularly relates to a coating and mordanting process for a semi-shading window decoration. The process sequentially comprises the following steps: preparing a gray fabric; blending aqueous mordanting paste, namely preparing following components in parts by weight: 25-45 parts of environment-friendly flexible glue, 13-18 parts of stiffening glue, 35-47 parts of water, 1-5 parts of an efficient penetrant, 0.01-0.02 part of a de-foaming agent, 0.2-1.5 parts of a color stabilizer, 0.5-1.5 parts of an ultraviolet absorbent and 8-10 parts of dye; mordanting and coating, namely putting the gray fabric into the aqueous mordanting paste and padding; rolling and coating by a compression roller under the condition that air pressure is 0.3-0.4Mpa and the speed is 10-15m / min; carrying out flattening treatment, namely adsorbing the paste in needle holes of the mordanted and coated gray fabric to remove the paste; and carrying out after-treatment, namely after drying at 165-180 DEG C, cooling by cold air. According to the preparation process, the mordanting paste and coating paste adopt the same aqueous mordanting paste so that the dyeing-mordanting step and the coating step are finished simultaneously and wastewater is reduced; meanwhile, the aqueous mordanting paste is safe and environmentally friendly and the green production can be realized.
Description
technical field [0001] The invention relates to a preparation process of a window decoration, in particular to a coating dipping process of a semi-shading window decoration. Background technique [0002] Although the dyed and finished products of modern textile coatings are bright and beautiful, the price paid behind the bright and beautiful colors is water pollution; printing and dyeingwastewater is discharged from printing and dyeing factories that mainly process cotton, hemp, chemical fibers and their blended products waste water; about 70-80% of textile waste water comes from printing and dyeing. Printing and dyeing wastewater has a large amount of water, 100-200 tons of water is consumed per ton of textile printing and dyeing, of which 80-90% becomes wastewater. Textile printing and dyeing wastewater has the characteristics of large water volume, high content of organic pollutants, high alkalinity, and large changes in water quality. It is one of the most difficult in...
