Quality Analysis Of Upper Tissue

With the rapid development of household paper in my country, the related technologies and research and development have been paid more and more attention by all parties in the paper industry. Understanding the application, development trend and process equipment of the core technology of household paper at home and abroad will help improve the market's Competitiveness is critical. Upper tissue is a type of toilet paper product used to wrap the absorbent core layer (fluff pulp and polymer water absorbent SAP) of sanitary products such as sanitary napkins and diapers. It is a toilet paper roll that has been longitudinally slit. It is an indispensable part in the production of disposable sanitary products such as sanitary napkins and diapers. This article mainly analyzes the quality requirements of upper tissue.

1. Quantification of upper tissue

The quantification of upper tissue and the difference in the quantification of the profile have a great impact on the production cost of the manufacturer. Under the condition that the tensile strength of the paper is sufficient, the smaller the basis weight, the lower the production cost.

2. Dry and wet tensile strength of upper tissue

The tensile strength is controlled according to the requirements of the base paper on post-processing equipment such as sanitary napkins and diapers. Once the base paper is broken due to insufficient tensile strength, the manufacturer will lose raw materials such as upper tissue, fluff pulp, and polymer absorbent resin, and the total production cost will increase significantly. The upper tissue used in diapers has high requirements on wet tensile strength. For example, the wet tensile strength is small, it is easy to break, and the fluff pulp is easy to aggregate into a group after absorbing water, which affects the user's comfort and is not good for its skin. In addition, the wet tensile strength should not be too high. The higher the wet tensile strength, the slower the transverse water absorption speed. Therefore, the relationship between the wet tensile strength and the transverse water absorption speed must be well grasped in the production process.

3. Air permeability of upper tissue

The upper tissue is mainly wrapped in fluff pulp in sanitary napkins. The quality of fluff pulp wrapping mainly depends on its air permeability. The greater the air permeability, the more uniform the fluff pulp will be wrapped, otherwise the worse the effect will be, which will eventually affect the use effect. At the same time, the higher the air permeability, the faster the water absorption speed, and the better the use effect.

4. Dustiness of upper tissue

Dustiness is the main indicator of the appearance quality of upper tissue. Dust appears in sanitary napkins and diapers, which on the one hand will make users feel uncomfortable, and on the other hand may cause excessive bacteria. At the same time, these manufacturers use infrared to monitor dust throughout the production process. As manufacturers attach importance to dust, dust degree ranks first in its various indicators.

Upper tissue belongs to the category of household paper, its air permeability and the speed of liquid absorption directly affect its use effect. With the continuous improvement of people's living standards, the market for sanitary products is getting bigger and bigger, and the quality requirements of the products are also getting higher and higher. upper tissue will surely become another bright spot in the paper industry.
