Embodiment A

[0061] (1) Dissolve 10 mol of cyanuric chloride and 20 mol of diethanolamine in 5L of absolute ethanol, first stir and react at 0°C for 1.5h, then raise the temperature to 45°C and stir for 2h;

[0062] (2) After the reaction, when the temperature of the above reaction solution was lowered to room temperature, 11 mol of 1,4-dichloro-n-butane was added, stirred for 3 hours, filtered and dried to obtain Modifier A.

Embodiment B

[0070] (1) Dissolve 10 mol of cyanuric chloride and 20 mol of diethanolamine in 5L of absolute ethanol, first stir and react at 0°C for 1.5h, then raise the temperature to 45°C and stir for 2h;

[0071] (2) After the reaction is finished, when the temperature of the above reaction solution is lowered to room temperature, add 10.5 mol of 1,4-dichloro-n-butane, react with stirring for 3 hours, and filter and dry to obtain modifier B.

Embodiment C

[0073] (1) Dissolve 10 mol of cyanuric chloride and 20 mol of diethanolamine in 5L of absolute ethanol, first stir and react at 0°C for 1.5h, then raise the temperature to 45°C and stir for 2h;

[0074] (2) After the reaction, when the temperature of the above reaction solution was lowered to room temperature, 12 mol of 1,4-dichloro-n-butane was added, stirred for 3 hours, filtered and dried to obtain modifier C.

Abstract

The invention discloses an organic dye adsorbent material. The organic dye adsorbent material comprises cellulose fibers and activated carbon fibers. A modifier is grafted to the cellulose fiber. The organic dye adsorbent material improves a saturation adsorption capacity of a cationic dye, an anionic dye and a non-ionic dye, improves a particle impurity adsorption capacity, improves sewage cleanliness, and reduces environmental pollution. The invention also discloses a preparation method of the organic dye adsorbent material. The preparation method comprises preparation of a modifier, a grafting reaction of cellulose fibers, mixing with activated carbon fibers, opening, combing, cross-type lapping and spunlace solidification. The preparation method has simple processes and mild conditions.

Description

technical field [0001] The invention relates to the technical field of light chemical industry, in particular to an adsorption material for absorbing dyes that come off from clothes during machine washing. Background technique [0002] In daily laundry cleaning, usually all the clothes that need to be washed are put into the washing machine at the same time, and then add water for drum washing; in industrial cleaning, due to the large number of work clothes, large washing machines are often used, and the work clothes washed each time The quantity exceeds hundreds of pieces. When all the clothes are washed together, the dyes from the clothes that are easy to fade are dispersed in the water, and it is easy to cross dye other white or light-colored clothes, thereby seriously damaging the appearance of the dyed clothes. In the catering and hotel industries, there are a large number of tablecloths and curtains that need to be washed uniformly. Because the curtains and tablecloth...
