Problems solved by technology

At this time, some clothes tend to fade easily, thus polluting water and other clothes, making the color of other clothes not correct and affecting the wearing effect
In order to avoid this situation, we can only choose to wash these textiles one by one, resulting in a lot of labor, water, electricity consumption and waste
[0003] The patent No. "201310020353.3" "Preparation method of color-absorbing fiber and color-absorbing nonwoven fabric" introduces an aqueous solution of cellulose ether cationic color-absorbing agent adjusted with basic compounds to post-treat viscose fiber, and then use conventional The process is washed, oiled and dried to prepare color-absorbing fibers and subsequent color-absorbing nonwoven fabrics. When the adsorption capacity of the polyquaternary ammonium salt adsorption groups grafted on the surface of the fibers reaches saturation, the color-absorbing fibers , it completely loses the ability to absorb color, and the ability to absorb color is limited

Abstract

The invention relates to a preparation method of dye-absorption hollow viscose fiber. The preparation method comprises the following steps: (1) preparing a sodium carbonate solution; (2) preparing a dye-absorption hollow fiber spinning solution; (3) spinning and forming fiber; (4) drafting and refining fibers; and (5) performing dye absorption on fibers. The prepared viscose fiber is strong in dye absorption capacity, good in dye absorption effect, green and environment-friendly, and incapable of causing any harm to human bodies, and the produced dye-absorption cloth is used for washing clothes without the need of classification, so that time can be saved, dark and light clothes can be washed together, the manual cost, water and electricity consumption and waste can be greatly reduced, and the scattered pigment can be strongly absorbed so as to prevent clothes from being dyed.

Description

technical field [0001] The invention relates to the field of viscose fiber production, in particular to a method for preparing color-absorbing hollow viscose fibers. Background technique [0002] When washing textiles such as clothes, pillow covers, scarves, bed sheets and quilts, people seldom wash them one by one, but put multiple pieces of textiles with similar color or similar functions together for hand washing or machine washing. At this time, some clothes tend to fade easily, thereby polluting water and other clothes, making the color of other clothes not correct and affecting the wearing effect. In order to avoid this situation, we can only choose to wash these textiles one by one, which has caused a lot of labor, water, and electricity consumption and waste. [0003] The patent No. "201310020353.3" "Preparation method of color-absorbing fiber and color-absorbing nonwoven fabric" introduces an aqueous solution of cellulose ether cationic color-absorbing agent adjust...
