Household paper and preparation thereof

Abstract

A household paper comprises at least one layer of single-wire paper. The single-wire paper is compounded by more than three stack-up arranged layers of fibrous layers. At least one layer in more than three layers of the fibrous layers is a fibrous layer formed by addedly banking high yield pulp, a least one layer in the same is a fibrous layer formed by staple sizing agent and at least one layer of the same is a fibrous layer formed by long stuff sizing agent. The invention further provides a preparation of the household paper. The fibrous layer formed by the long stuff sizing agent is tough, the fibrous layer formed by the staple sizing agent is soft, and the fibrous layer formed by the addedly banked high yield pulp is smooth on the surface; in addition, the addedly banking increases overall whiteness of the high yield pulp fibrous layer, and fine filler granules are filled between fibers of high yield pulp, and surface smoothness of the high yield pulp fibrous layer is increased. Therefore, addedly banked high yield pulp is utilized in the household paper, characteristic requirements of various aspects of the household paper are guaranteed.

Description

technical field [0001] The invention relates to a living paper and a preparation method thereof. Background technique [0002] Household paper is a necessity in people's daily life, including napkins on the dining table, facial tissues in the living room, roll toilet paper in the bathroom, paper towels, and paper towels in the kitchen. At present, most household paper products are made from bleached chemical pulp. However, the yield of chemical pulp produced by the prior art is low (generally 40%-60%), which is not conducive to saving wood resources. In order to better save wood resources and reduce costs, the current method is to replace chemical pulp with high yield. High-yield pulp is usually pulp made from plant fiber raw materials through mechanical methods or a combination of chemical and mechanical methods. Since the non-cellulose components in the original wood material are retained, the yield of high-yield pulp Between 65%-95%. [0003] However, the paper made f...

Problems solved by technology

[0003] However, the paper made from high-yield pulp also has the following defects: (1) Since high-yield pulp retains a large amount of lignin, the purpose of the bleaching process is to transform lignin rather than remove it, so it contains high-yield bleaching The paper whiteness of pulp is lower than that of paper made from 100% bleached chemical pulp, and the paper made from high-yield pulp still has the phenomenon of yellowing under the action of light and heat, which affects the quality of household paper used in the process of use. (2) The special pulping method causes the fibers in the high-yield pulp to be shorter and thicker than those in the chemical pulp, and there are more fine fibers and fiber fragments in the pulp than in the chemical pulp , based on the characteristics of fibers in high-yield pulp, tissue paper made from high-yield pulp has low strength and rough surface feel
