Embodiment 1

[0023] (1) Take 0.1 part of potassium permanganate (parts by weight, 100 parts of water), add deionized water and stir for 1 min at 40°C to 50°C to make a fiber surface activation treatment solution for use;

[0024] (2) Take 50 parts of acrylamide, add deionized water and stir at 60°C to 80°C for 5 minutes, use sulfuric acid to adjust the pH value to 3.5, and make a fiber wet strength enhancement surface treatment solution for use;

[0025] (3) Add 45 parts of glutaraldehyde into deionized water and stir for 5 minutes at 60°C to 80°C to prepare a surface chelation treatment solution for use;

[0026] (4) Place the pretreated fibers such as cleaning, degumming, and drying in the treatment tank of the surface activation treatment solution prepared in the above (1), and immerse them for 20 to 30 minutes at 40°C to 50°C;

[0027] (5) Lead the impregnated fiber out of the treatment tank, wash it until there is no obvious pink color, and then pass it through the treatment tank equi...

Embodiment 2

[0032] According to the process of Example 1, take 0.2 parts of potassium permanganate, 50 parts of polyhexamethylene adipate; then take 45 parts of glutaraldehyde, and carry out wet strength enhancement treatment on the surface of viscose fiber to obtain high wet strength of viscose fiber.

Embodiment 3

[0034] According to the process method of Example 1, take 0.2 parts of potassium permanganate and 50 parts of polyacrylamide with a low degree of polymerization; then take 45 parts of glutaraldehyde, and carry out wet strength enhancement treatment on the surface of viscose fiber to obtain high wet strength polyacrylamide Viscose fiber.

Abstract

The invention discloses a surface treatment technology of improving the wet strength of fiber, which is characterized in that the technology is to preparea surface activation solution with surface active agent plus deionized water; scatter and stir with wet strength improving agent plus deionized water; regulate the pH value with sulfuric acid to prepare the wet strength improving treatment solution; stir with chelating agent plus deionized water to prepare the chelating treatment solution; put the pretreated fiber into the treating cell of the surface activation solution to soak; and then lead the fiber after soaking and treatment out of the treating cell, and conduct gracopolymerization in the treating cell with wet strength improving agent; treat with the treating cell with surface chelating treatment solution; next, lead the fiber after chelating treatment in a high temperature treating chamber to conduct high temperature solidification; and finally the adhesive fiber with high wet strength is obtained after cleaning and drying. The fiber after improved and treated by the wet strength improving agent of the invention has long-lasting high wet strength, washing resistance, and the whole technological process has no pollution harm, which is good for environmental protection and health of human beings.

Description

technical field [0001] The invention relates to a viscose fiber surface treatment process, in particular to a viscose fiber wet strength enhancement surface treatment process for regenerated cellulose fiber surface treatment. Background technique [0002] Viscose fiber has great development potential due to its special handle, luster and other advantages. At present, the main development direction of viscose fiber is concentrated in two aspects of environmental protection and new varieties. The research of environmental protection is to reduce the cost of treatment and the pollution to the environment by controlling the discharge of waste gas, wastewater and liquid in industrial production. For example, the invention patent of "Total Waste Gas Treatment Method and Device for Viscose Fiber Production" with publication number 1070129 is mainly focused on the new solvent lyocell project, high strength and high wet modulus, high crimp cellulose staple fiber project, viscose fila...
