Is the tissue really clean? Why?

Although the paper towel is only one inch thin, its hygiene cannot be ignored.

Paper towels with different cleanliness are also suitable for different occasions. The selection criteria of facial tissue and toilet paper are also different.

From the perspective of pulp raw materials, toilet paper and toilet paper can use waste paper raw materials, that is, recycled paper. However, natural wood pulp must be used for household paper and kitchen paper. From the hygienic standard, that is, microbial indicators, the total number of colonies in toilet paper and toilet paper should not exceed 600 per gram, and toilet paper and kitchen paper should not exceed 200. We can see that the former is not as strict as the latter.

Moreover, the workshops of household paper and kitchen paper must be disinfected and isolated according to the standards of disposable sanitary products, while toilet paper and toilet paper have no special requirements.

Toilet powder is a frequent visitor in the process of making paper towels. A small amount of talcum powder is no problem. It is mainly used to eliminate the resin in the process and avoid the adhesion pollution of blanket and the hole defect of paper. Basically, every paper towel manufacturer will add it, but too much is suspected of reducing the cost, because the natural wood pulp you want to buy with money is replaced by talcum powder.

Up to now, the proportion of medium and long fibers is also a big problem. Short fiber is also inevitable. Long fibers provide strength, while short fibers provide thickness and softness. All long fibers can't produce comfortable paper towels. However, blindly increasing the proportion of short fibers and weak hydrogen bonding will lead to low strength of paper towels, easy to break and brittle, dusty and powdery during use.

The higher the thickness and strength, the better. In the final analysis, it depends on the use comfort and functional satisfaction.
