Abstract

The invention discloses toilet paper prepared with the bleaching technology, and belongs to the technical field of papermaking. The toilet paper is prepared through secondary pretreating, washing, screening, bleaching, pulping, decontaminating and degassing, pulp screening, squeezing, drying, pressing polishing, reeling, rewinding, cutting and packaging. The toilet paper prepared with the bleaching technology is high in brightness, tensile index and flexibility; the produced toilet paper is free of any stimulation or adverse reaction to the skin of the human body.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of papermaking, and in particular relates to toilet paper prepared by a bleaching process. [0003] 【Background technique】 [0004] The current pulp production methods mainly include chemical, semi-chemical, mechanical and chemical-mechanical processes. Among them, chemical pulping occupies a dominant position among many pulping methods at present. The pulp prepared by chemical cooking is called natural pulp. The low brightness of natural pulp limits its application. Generally, natural pulp can only be produced after bleaching to produce higher-grade paper. [0005] Household paper, especially toilet paper, is a commonly used daily consumer product. However, due to the psychological need for whiteness and some physical indicators, it is usually made of pulp mainly made of bleached wood pulp. Even if all straw pulp is used to prepare toilet paper, bleached pulp is also used, but the yield and whiten...
