Problems solved by technology

[0004] However, the nonwoven fabric has low strength, is easy to deform, and has a lot of surface fiber leakage, especially after the viscose nonwoven fabric reacts in a high-temperature alkaline aqueous solution, it needs to be dried at a high temperature before it can be used. After this process, it will become brittle and its strength will decrease, so the nonwoven fabric will become wrinkled after this process, the size shrinks significantly, and the surface fiber leakage is very serious. The nonwoven fabric obtained in this way is not only ugly in appearance, but also broken The strength and tear strength are signif

[0029] Combining the above core ideas, the present invention provides a method for preparing color-absorbing fibers, including:

[0030] Step S11, preparing a cationic cellulose ether aqueous solution with a concentration of 5g / L-100g / L, adding an alkaline compound to the cationic cellulose ether aqueous solution to adjust the pH value to 11-13, and putting viscose fibers into the In an aqueous solution of cationic cellulose ether, react at 80°C to 100°C for 15 minutes to 60 minutes to obtain polyquaternary ammonium salt viscose fiber, wherein the mass ratio of the cationic cellulose ether to the viscose fiber is 1:10 ~1:1;

[0031] In step S12, the polyquaternium viscose fiber is taken out and dried to obtain a color-absorbing fiber.

[0032] Further, the present invention also provides a method for preparing a color-absorbing nonwoven fabric, comprising:

[0033] Step S21, providing the color-absorbing fiber;

[0034] Step S22, laying the color-absorbing fiber;

[0035] ...

no. 1 example

[0038]First, proceed to step S11, configure a cationic cellulose ether aqueous solution with a concentration of 5 g / L, add a basic compound to the cationic cellulose ether aqueous solution to adjust the pH value to 11, and optionally, the basic compound is Sodium, potassium hydroxide, potassium amide or sodium amide, wherein the solubility of the basic compound is not limited, as long as the pH value of the cationic cellulose ether aqueous solution is adjusted to 11. Put the viscose fiber into the cationic cellulose ether aqueous solution and react at 100°C for 50 minutes to obtain polyquaternium viscose fiber, wherein the mass ratio of the cationic cellulose ether to the viscose fiber is 1 : 10. The cationic cellulose ether can be adsorbed on the surface of the viscose fiber, and under the high-temperature alkaline environment, the cationic cellulose ether adsorbed on the surface of the viscose fiber reacts to generate polyquaternary ammonium salt adsorption groups , the pol...

[0051] The second embodiment is based on the first embodiment, the difference is that the ratio of various raw materials is different, see the following description for details.

[0052] First, proceed to step S11, prepare a cationic cellulose ether aqueous solution with a concentration of 100 g / L, and add a basic compound to the cationic cellulose ether aqueous solution to adjust the pH value to 13. Put the viscose fiber into the cationic cellulose ether aqueous solution and react at 80°C for 15 minutes to obtain polyquaternium viscose fiber, wherein the mass ratio of the cationic cellulose ether to the viscose fiber is 1 : 1.

[0053] Then, proceed to step S12, take out the polyquaternary ammonium salt viscose fiber and dry it to obtain the color-absorbing fiber.

[0054] The dried color-absorbing fiber was subjected to MSDS test, and the test result showed that the polyquaternium salt content in the color-absorbing fiber was 40%, which proved that the polyquaternium salt w...

Abstract

The invention discloses a preparation method of dye-absorption fibers. The preparation method of the dye-absorption fibers comprises the steps that a cationic cellulose ether aqueous solution with the concentration of 5g/L-100g/L is prepared, an alkali compound is added to the cationic cellulose ether aqueous solution to adjust the pH value to be 11-13, viscose is put into the cationic cellulose ether aqueous solution to be reacted for 15-60 minutes at the temperature of 80-100 DEG C, and poly quaternary ammonium salt viscose is obtained; the poly quaternary ammonium salt viscose is taken out and dried, and then the dye-absorption fibers are obtained. The invention further provides a preparation method of dye-absorption non-woven cloth. The preparation method of the dye-absorption non-woven cloth comprises the steps that the dye-absorption fibers are provided; lapping is carried out on the dye-absorption fibers; net fixation is carried out on the dye-absorption fibers after lapping, and the cloth is obtained. By means of the preparation method of the dye-absorption fibers and the preparation method of the dye-absorption non-woven cloth, dye-absorption non-woven cloth with high absorption force and tearing resistance can be prepared.

Description

technical field [0001] The invention relates to the technical field of light chemical industry, in particular to a method for preparing a color-absorbing fiber and a color-absorbing nonwoven fabric. Background technique [0002] 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 off from the clothes that are easy to fade It will disperse in water, and then cross-dye other white or light-colored clothes, resulting in serious damage to the appearance of the dyed clothes. Therefore, at present, if it is found that the clothes that are obviously easy to fade can only be washed separately, which not only wastes water and electricity resources, but also is troublesome. [0003] Non-woven fabrics, also known as non-woven fabrics, are composed of directional or random fibers. Th...
