Abstract

The invention discloses a method for preparing dyed wood pulp paper for nonwoven materials, which comprises the following steps of: (1) mixing red pine fluff pulp and coniferous wood pulp to obtain mixed wood pulp; (2) dispersing the pulp, namely putting the mixed wood pulp obtained in the step (1) into a pulp dispersing tank, and adding water for pulping, so that wood pulp fibers are dispersed in the water uniformly; (3) heating, namely heating the water in the pulp dispersing tank; (4) dyeing, namely dyeing dyes in the pulp dispersing tank for 15 to 30 minutes, adding a color fixing agent, and fixing colors for 20 to 30 minutes; and (5) conveying dyed slurry obtained in the step (4) into a fourdrinier part of a papermaking machine for forming, and squeezing, drying, coiling and slittingto obtain the dyed wood pulp paper for the nonwoven materials. Compared with imported wood pulp paper, the dyed wood pulp paper produced by the method has the advantages that: the color fastness to sunlight and water leaching fastness are improved greatly; indexes are higher than the level of foreign products; and the cost is reduced.

Description

technical field

[0001] The invention relates to a preparation method of dyed wood pulp paper for nonwoven materials. Background technique

[0002] Wood pulp composite spunlace nonwoven material is a kind of new nonwovens for medical and sanitary use made of wood pulp paper made of special natural wood pulp fibers and carded fiber web (viscose, polyester, etc.) through spunlace nonwoven technology. Materials and products are mainly used as disposable medical products such as surgical gowns, surgical sheets, and protective clothing. Before the present invention, there was no manufacturer in my country to specially produce wood pulp paper (comprising natural color and dyed wood pulp paper) for the production of spunlace nonwovens, and the products were all imported from abroad. Due to the limitations of the original wood pulp paper production process, the imported dyed wood pulp paper has poor color fastness (light fastness, water immersion, soaping, alcohol resistance, etc.) ...
