Quality Analysis of Tissue Lining Paper

With the rapid development of household paper in China, all parties in the paper industry pay more and more attention to the related technology and R & D. It is very important to understand the application, development trend and process equipment of the core technology of household paper at home and abroad to improve the market competitiveness. Tissue lining paper is a kind of toilet paper product, which is used to wrap the absorbent core layer (fluff pulp and high molecular absorbent resin SAP) of sanitary products such as sanitary napkins and diapers. It is a kind of toilet paper roll that is cut longitudinally and is an indispensable part of the production of sanitary napkins, diapers and other disposable sanitary products. This paper mainly analyzes the quality requirements of upper tissue.



1.Quantification of tissue lining paper

The quantity of tissue lining paper and the size of the banner quantity difference greatly affect the production cost of the manufacturer. When the tensile strength of the paper is sufficient, the smaller the weight, the lower the production cost.


2.Dry and wet tensile strength of tissue lining paper

Tensile strength is controlled according to the requirements of base paper on post-processing equipment such as sanitary napkins and diapers. Once the base paper breaks due to insufficient tensile strength, the manufacturer will lose such raw materials as tissue lining paper, fluff pulp, polymer water absorbent resin, and the total production cost will increase significantly. The tissue lining paper used in diapers needs high wet tensile strength. If the wet tensile strength is small, it is easy to break, and the fluff pulp is easy to gather into a mass after absorbing water, which affects the comfort of the user and is not conducive to the user's skin. In addition, the wet tensile strength should not be too high. The higher the wet tensile strength, the slower the lateral water absorption rate. Therefore, in the production process, we must master the relationship between wet tensile strength and transverse water absorption velocity.

3.Permeability of tissue lining paper

Tissue lining paper is mainly wrapped with fluff pulp in sanitary napkins. The quality of fluff pulp wrapping mainly depends on its air permeability. The better its permeability is, the more evenly the fluff pulp is wrapped. On the contrary, the worse the effect is, and finally the use effect will be affected. At the same time, the higher its permeability, the faster its water absorption speed, and the better its use effect.


4.Dust degree of tissue lining paper

Dust degree is the main indicator of the appearance quality of tissue lining paper. If there is dust in sanitary napkins and diapers, on the one hand, it will make users feel uncomfortable, on the other hand, it will also lead to excessive bacteria. At the same time, these manufacturers will use infrared ray to monitor dust throughout the production process. With the manufacturers' attention to dust, the dust degree ranks first in all indicators.

upper tissue

Tissue lining paper belongs to the category of household paper. Its air permeability and liquid absorption speed directly affect its use effect. With the continuous improvement of people's living standards, the market of sanitary products is becoming larger and larger, and the requirements for product quality are becoming higher and higher. Upper tissue will become another highlight of the paper industry.
