1. Appearance
Take a look at the outer packaging. When choosing toilet paper, check the outer packaging first. The packaging and sealing of the product should be neat and firm, without damage; the packaging should be printed with the manufacturer's name, production date, product grade (superior product, qualified product), adopted standard number, implemented sanitary standard number (GB20810-2006) and other information . Second, look at the appearance of the paper. The surface of the paper should be clean. There should be no obvious dead folds, incompleteness, breakage, hard blocks, raw grass tendons, pulp masses and other paper diseases and impurities. The paper should not be severely shed or dropped when used. Powder phenomenon, there should be no residual printing ink in the paper.
2. Quantitative
Refers to whether the quantity or the number of sheets is enough. According to relevant regulations, it is generally a product with a net content of 50 grams to 100 grams, and the negative deviation shall not exceed 4.5 grams; for a product of 200 grams to 300 grams, it shall not exceed 9 grams.
3. Whiteness
The whiteness of toilet paper is related to raw materials, such as the choice of raw materials for cotton pulp and wood pulp.
If cotton pulp is added with starch, the density of the pulp powder will be more uniform and clean. Just like the effect of people washing the sheets (cotton fabric used to make cotton quilts) in the past, the cotton cloth is clean and tidy without wrinkles after pulp washing. Using cotton stalks and cotton linters as raw materials, it is made by heating with a proper amount of alkaline water at high temperature, and contains pure cellulose. The fiber is slender and elastic, tough and resistant to bending, and has good absorbency. The paper produced is fine, soft, and highly opaque. Cotton linters are coarse cotton wool that is used for weaving and filtering through the first process of rolling the fine cotton wool part of cotton. For example, cotton stalks are rich in grass and wood fibers, and there are some short fibers remaining on cotton seeds (hair seeds). These short fibers are peeled off with a fleece machine, which is called "cotton linters." Cotton linters are composed of three parts; the first part comes from the longer fibers of the "hair"; the second part comes from the fibers on the wool seeds that are crushed by the gin; the third part is a layer of short and natural growth on the epidermis of the cotton seed. Dense fiber, which is the main component of cotton linters.
4. Water absorption
You can put water droplets on it to see how fast the absorption is. The faster the speed, the better the water absorption.
5. Lateral Tensile Index
What is the toughness of the paper and is it easy to break when used. Pure wood pulp paper has high tensile force, good toughness and not easy to break due to its long fiber.
6. Softness
This is an important indicator of toilet paper products. Good toilet paper should give people a soft and comfortable feeling. The main reasons that affect the softness of toilet paper are the fiber raw materials and creping process of toilet paper. Generally speaking, cotton pulp is better than wood pulp, and wood pulp is better than wheat straw pulp. Toilet paper with excessive softness feels rough to use.
7. Hole
The hole index is the limit requirement for the number of holes on wrinkled toilet paper. The holes will affect the use of paper. Wrinkled toilet paper with too many holes will not only have poor appearance, but also easily break during use, which affects the wiping effect.
8. Dust degree
In layman's terms, there is not much dust on the paper. If the raw material is wood pulp, there is no problem with dust. However, if recycled paper is used as a raw material and the process is not handled properly, it will be difficult to meet the dust level.
