Background: Knowledge tissue paper machine of toilet paper
I. Introduction

Toilet paper refers to disposable toilet tissue used in people's daily lives, the raw material is usually wood, straw (wheat straw, reed pulp, bagasse pulp, bamboo, etc.) or waste paper pulp and other products are required to have good flexibility resistance, strength and water absorption, and require health, in order to ensure the health of consumers.

Our toilet paper implementation of mandatory national standards GB20810-2006 "toilet paper (including toilet paper)," which provides a quantitative standard brightness (whiteness), lateral aspiration height, tensile strength, flexibility, holes, dust degree, cross The total number of goods and other technical indicators moisture and bacteria, coliform, Staphylococcus aureus, hemolytic streptococcus and other microorganisms indicators, while the raw material and press the "life-time tissue processing enterprises supervision regulation" (The National Quality Executive [ 2003] No. 289) to perform, you can use the virgin fiber, recycled paper prints, print White side for raw materials may not be used discarded household paper, medical paper, packaging paper as raw material, the use of recycled printed paper as a raw material, It must be printed on recycled paper deinking process. Currently the International Organization for Standardization (ISO) and the European Union, Canada, Australia also no toilet paper to develop specific product standards. United States, Japan, South Korea, South Africa and other countries formulate product standards, but mainly on the physical performance requirements of toilet paper to make provision, which the United States mandatory requirements of toilet paper containing 50% recycled fiber, to promote paper recycling and reduce environmental pollution. China Taiwan region's only standard for chemicals, pigments and dyes to make a health claim regulations. By contrast, the national standard of toilet paper from a product performance, raw materials and microbiological indicators of three aspects of the quality of toilet paper requests, wherein the microorganism indicator is standard in other countries and regions not provided. Therefore, my toilet paper national standards relative to other countries and regions is a more stringent standard, in line with national standards of toilet paper products should be safe and reliable.

Second, on the toilet paper used in the production of chemical additives in question

The main raw materials of plant fiber toilet paper, toilet paper when you need to use a certain degree of water absorption, softness and good dry and wet strength, in order to achieve and meet these performance requirements, the toilet paper during papermaking need to add some chemical additives The main wet strength agent, dry strength agents, dispersing agents, softening agents and the like. The part of the chemical additives are natural polymers, non-toxic non-irritating, dry enhancer such as starch; part belonging synthetic or polymer, according to the European Chemicals Agency (ECHA), the United States Food and Drug Administration (FDA ) and other published safety data, these synthetic polymers or in addition to individual chemical additives, the domestic and other chemical agents, there are no safety assessment data. Since the toilet paper in the papermaking process, the pulp is diluted to 0.25% to 0.5% of the concentration of the chemical additives are mostly water-soluble substance, used in an amount less papermaking process in an amount not more than 2%, and then dehydrated and When made of toilet paper drying process, residual amounts of these chemicals in the toilet paper is very low, in the case of normal use in contact with the skin transfer amount is very small, generally considered the human body during normal use is safe. When using raw materials to produce toilet paper, deinking agents need to be added deinking and bleaching agent and purification, dehydration and   tissue paper machine  drying time after the formation of toilet paper, the residual amount of deinking agents and bleach has been very low, normal use is not It will have an impact on the health of consumers.

Third, on the toilet paper fluorescent brightener problem

Fluorescent brightener is a fluorescent dye, widely used in the textile, paper, detergents, plastics, and other industries. Join fluorescent brighteners in the paper industry can improve the appearance of the paper to make paper white, and can reduce the cost of pulp bleaching, reduce energy consumption, reduce environmental pollution. Paper industry culture paper, printing paper and paperboard and other products in a fluorescent whitening agent is required, the amount is generally 0.05% to 0.2%. Our paper has also added some varieties restrict fluorescent whitening agents, such as direct contact with food or food packaging for food packaging and paper containers, cigarette paper. Household paper in paper towel, toilet paper at home and abroad has not been added to the fluorescent whitening agent to make restrictions. Fluorescent brightener contained in our tissue products, a source of business in order to improve whiteness added fluorescent whitening agent in the production process. Another source is the enterprise using waste paper as raw material, waste paper itself contains fluorescent whitening agent, can not be completely removed paper into optical brighteners during paper processing and remains in tissue paper products. For long-term use of toilet paper containing fluorescent whitening agents possibly carcinogenic to media reports, through the World Health Organization (WHO), the United States Environmental Protection Agency (EPA), the US Food and Drug Administration (FDA), the EU  tissue paper machine   Joint Research Centre (JRC), The European Food Safety Authority (EFSA) and other authorities relevant research results analysis, whether the use of a fluorescent whitening agent at home and abroad have toilet paper in the consumer health hazard lack of relevant research data, domestic production of toilet paper were not clear prohibiting the use of optical brighteners.
