Embodiment 1

[0037] Mix 100 parts of viscose fiber, active solid cationic etherification agent 2, 30 parts of 3-epoxypropyltrimethylammonium chloride and 2 parts of alkaline compound sodium hydroxide to adjust the pH value of the solution to 10; The number of parts is a mass percentage; the temperature of the mixture in the first step of heating and holding is 60 ° C and the first step of draining and cleaning once; after the first step of draining and cleaning, add 1 part of oxalic acid; and then carry out the second step of heating And the temperature of the heat preservation is 60 ℃, the second step is to drain and wash once; the obtained viscose fiber is produced into a spunlace non-woven fabric by the spunlace method; the spunlace non-woven fabric coil is cut into pieces, supplemented by packaging . Finally, a color-absorbing cloth is obtained.

Embodiment 2

[0039] 100 parts of viscose fiber, active solid cationic etherification agent 2, 45 parts of 3-epoxypropyltrimethylammonium chloride and 4 parts of alkaline compound sodium hydroxide are mixed together to adjust the pH value of the solution to 12; The number of parts is the mass percentage; the temperature of the mixture in the first step of heating and heat preservation is 75 ° C and the first step of draining and cleaning 2 times; after the first step of draining and cleaning, add 3 parts of oxalic acid; then carry out the second step of heating And the temperature of the heat preservation is 70 ℃, the second step is to drain and wash twice; the obtained viscose fiber is produced into a spunlace non-woven fabric by the spunlace method; the spunlace non-woven fabric coil is cut into pieces, supplemented by packaging . Finally, a color-absorbing cloth is obtained.

Abstract

The invention relates to a method for preparing color absorption fabric. The method includes the following steps that (1) 100 by mass parts of viscose fibers, 30-60 by mass parts of an active solid cationic etherifying agent and 2-6 by mass parts of an alkali compound are mixed, and the PH value of a solution is adjusted to be 10 to 13; (2) the mixture in the step (1) is subjected to primary heating, temperature keeping and primary liquid feeding washing; (3) the mixture is subjected to secondary heating, temperature keeping and secondary liquid feeding washing; (4) the viscose fibers obtained in the step (3) is produced into spunlace nonwoven fabric with the spunlacing method; (5) a spunlace-nonwoven-fabric coiled material is cut into slices and additionally packed. By means of the color absorption fabric prepared with the method, the problem that dark color clothes and undertint clothes cannot be jointly washed is solved, more energy sources such as water and electricity are saved, time of consumers is also saved, the cloth washing efficiency is improved, and the cloth washing cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a method for preparing color-absorbing cloth and its product. Background technique [0002] At present, due to various reasons, clothes often lose color when washing, especially dark clothes, and these colors dropped in the water are easy to contaminate other clothes washed at the same time, especially light-colored and white clothes. Cause cross-color problem. If the color crossing is light, it will affect the original color luster of the clothes, destroying the quality and grade of the clothes, and if it is serious, it will directly cause serious color mixing of the clothes and be forced to be discarded. [0003] In the washing of clothes in daily life, generally all the clothes that need to be washed are placed in the washing machine together, and then add water to stir or wash in a drum. Since all the clothes that need to be washed are together, the dye that falls ...
