Abstract

The invention provides an application of corncob fibers in preparing tissue paper, wherein the tissue paper includes corncob fibers and long fibers, and the fiber length of the long fibers is greater than the fiber length of the corncob fibers; The fiber length of the corncob fiber is 0.01mm-1.0mm; the content of the corncob fiber in the tissue paper is 5wt%-95wt%. In the present invention, the corncob fiber contains a large amount of cellulose, and its fiber length is short, and the shorter corncob fiber has an important influence on the softness of tissue paper, and can improve the quality of tissue paper. Softness, the content of the corncob fiber in the tissue paper is 5wt% to 95wt%, so that the long and short fibers cooperate with each other to obtain the tissue paper with better softness. Compared with the prior art, the corncob fiber is applied to the preparation of tissue paper in the present invention, and the tissue paper prepared by the present invention has better softness.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to the application of corn cob fiber in preparing household paper. Background technique [0002] Household paper refers to all kinds of hygienic wiping paper used to take care of personal homes and going out, including roll toilet paper, removable toilet paper, facial tissue, napkins, paper towels, kitchen paper towels, etc. [0003] The raw materials used in the manufacture of tissue paper include virgin pulp of plant fibers and recycled waste paper pulp. Recycled waste paper pulp is secondary pulp, which contains a large number of harmful substances such as pathogenic microorganisms and chlorine elements, and the hygienic quality is difficult to guarantee, which will affect the health of consumers. Therefore, the use of plant fiber virgin pulp as a raw material to prepare household paper has received people's attention. The plant fiber raw pulp used in the prior art to prepa...
