Usually, the manufacture of toilet paper raw materials are many, commonly used cotton pulp, wood pulp, bamboo pulp, grass pulp and other natural and non-polluting raw materials. Toilet paper requires no toxic chemicals, no raw materials that are irritating to the skin, and no moldy viral bacterial residue.
Tissue raw materials can be waste paper, straw, reeds, sugar cane, wood, etc., that is to say, plants containing fibers can be used to make paper, but due to the papermaking process will produce a variety of pollution, and different raw materials processed with different costs of toilet paper, taking into account these aspects, it is necessary to choose enough fiber raw materials to be good.
But these raw materials are not processed into toilet paper in one step, but after many steps of processing, such as the use of waste paper as raw materials, waste paper to be broken, deinking, bleaching, and then mixed with talc, whitening agents and other reagents, and then into the paper-making equipment, after pressing, drying, rolled into a large axle of paper, and then through the paper molding equipment to process into our daily use of the Tissue paper.
Two, toilet paper raw materials which is good
1, 100% virgin wood pulp
Strong water absorption, less paper shavings, paper on the fine grain, soft touch, strong toughness, can be said to be the best quality of toilet paper, just than the price of ordinary toilet paper is also a little expensive.
2, half-wood pulp
Good water absorption, suitable for toilet paper, but used to do facial tissue will produce confetti, moderately priced, cost-effective.
3, bamboo pulp
The visual sensory effect is very good, but the water absorption, toughness and softness are general. Bamboo pulp paper is the emergence of recent years, bamboo pulp as raw material, paper brittle.
4, grass pulp
Water absorption is poor, more paper shavings, water deformation is serious. If you don't want to buy too expensive toilet paper, inexpensive 100% grass pulp is a good choice. But compared to 100% virgin wood pulp paper, the grain on the toilet paper paper is very coarse, looks unattractive, and does not feel delicate.
5, recycled pulp
Recycled pulp made of toilet paper contains waste newspaper and other recycled materials. This type of paper is characterized by thin and thin, not clean, rough feel, and even with the naked eye can be seen in the stars and grass fragments. This raw material made of toilet paper is very unhygienic and harmful to the body's health, so we are advised to buy with caution.
Three, the difference between napkins and toilet paper
1, the standard is different
(1) different bacterial content
Napkin directly in contact with the face, the health requirements are very strict, the state requires that the bacterial content of each gram of napkins shall not be higher than 200 units. The requirements of the toilet paper is relatively loose, each gram of toilet paper containing bacteria is not higher than 600 units even if it is qualified. That is to say, the bacterial content of toilet paper is three times that of napkins, with toilet paper to wipe your face, the more you wipe the dirtier it may be!
(2) different papermaking wood pulp
100% virgin wood pulp refers to the papermaking wood pulp are new raw materials, according to the national health standards, napkins must use virgin wood pulp, so the market to see the "pure wood pulp napkins" must not buy.
Pure wood pulp allows the existence of recycled materials, recycled materials made of toilet paper is in line with national health standards, in addition to living paper, medical paper and packaging paper other than waste paper, can be processed into toilet paper.
(3) different fluorescent whitening agent requirements
Napkin to contact with the human face, according to the regulations must not contain migratory fluorescent whitening agent, qualified napkins can be used without fear of damage to the skin.
And health standards for toilet paper contains migratory fluorescent whitening agents, the content of how much are not clear requirements, accustomed to wipe the face with toilet paper friends should pay attention to.
2, the use of different
(1) napkins: facial paper
Napkin, napkin is specifically designed to clean the face, soft skin, the highest health requirements, used to wipe the mouth, wipe the face safer. In addition, napkins are better toughness after wetting, not easy to break, wipe sweat when the confetti will not remain on the face.
(2) Toilet paper: toilet paper
Toilet paper is moderately soft, mainly used when going to the toilet. Qualified brand toilet paper will not cause harm to the human body, although the health standard is not as high as napkins, but the amount and cheap.
Four, how to buy toilet paper
1, look at the appearance
The selection of toilet paper should first check the packaging. Product packaging seal should be neat and firm, no breakage; packaging should be printed with the name of the manufacturer, date of production, product grade (superior, first-class, qualified products), the use of standard number, the implementation of health standard number (GB20810-2006) and other information. Second look at the appearance of the paper, the paper surface should be clean, there should be no obvious dead folds, mutilated, broken, rigid block, raw grass tendons, pulp and other paper diseases and impurities, paper should not be serious when using hair, powder phenomenon, there should be no residual printing ink in the paper.
2, test weight
that is, the portion or the number of sheets enough, according to the relevant provisions, generally is the net content of 50 grams to 100 grams of goods, the negative deviation shall not exceed 4.5 grams; 200 grams to 300 grams of goods, shall not exceed 9 grams.
3, look at the whiteness
Toilet paper is not the whiter the better, it is possible to add an excessive amount of fluorescent bleach. Fluorescent agent is the main cause of dermatitis in women, long-term use may also cause cancer. How to recognize whether the fluorescent bleach is excessive? First of all, with the naked eye should be natural ivory white, or put the toilet paper in the ultraviolet light (such as money detector) under the irradiation, if there is a blue fluorescence, it proves that contains fluorescent agent. The bright white over low although it does not affect the use of toilet paper, but the use of raw materials is poor, the same try not to choose these products.
4, test absorbency
Water can be dripped on it to see how fast the absorption rate, the faster the rate of absorbency the better.
5, test lateral tensile index
is the toughness of the paper, whether it is easy to break when used. Pure wood pulp paper due to long fibers, so tensile strength, good toughness, not easy to break.
6, look at the softness
This is an important indicator of toilet paper products, good toilet paper should give people a soft and comfortable feeling. The main reason affecting the softness of toilet paper fiber raw materials, wrinkling process. Generally speaking, cotton pulp is better than wood pulp, wood pulp is better than wheatgrass pulp, softness exceeds the standard toilet paper used to feel rough.
7, look at the hole
The hole indicator is the number of holes in the wrinkled toilet paper on the limited requirements, holes will have an impact on the use of paper, too many holes in the wrinkled toilet paper not only look bad, in use, but also easy to break, affecting the effect of wiping.
8, look at the degree of dust
To put it plainly, the paper is dusty or not. If the raw material is virgin pulp, dust is not a problem. But if you use recycled paper as raw materials, and the process is not appropriate, the dust degree is difficult to meet the standards.
