Absorbent article

Abstract

The invention discloses an absorbent article, which comprises a water-permeable surface layer, an absorber and a water-repellent back layer. The permeable surface is in direct contact with the skin. From the proximal side to the distal side, the water-permeable surface layer is successively provided with an upper water-permeable surface layer and a lower water-permeable surface layer, wherein thefibers of the lower water-permeable surface layer are arranged to extend roughly in the length direction of the absorbent article, and the hydrophilicity of the lower water-permeable surface layer isgreater than the hydrophilicity of the upper water-permeable surface layer. As a result of the above structure, it may be ensured that liquid impurities including urine rapidly penetrate through the water-permeable surface layer, to ensure that a diaper has the characteristics of being dry and smooth.

Description

technical field [0001] The present invention relates to the field of absorbent articles, such as diapers, diapers, incontinence protectors or sanitary napkins. Background technique [0002] Due to the low barriers to entry in the disposable sanitary products industry, more and more new companies are emerging, and there are more and more types of disposable sanitary products that people can come into contact with. Now diapers have been widely used in the elderly, patients with special diseases and infants. Especially for infants and young children, diapers have become one of the indispensable daily necessities in the growth process of babies. [0003] Diapers are a kind of disposable absorbent articles that have grown rapidly in recent years, and the quality of products from various manufacturers is uneven. Although most manufacturers are constantly pursuing products that are thin, breathable, and dry, in order to meet the needs of quick sales, product performance often sta...

AI Technical Summary

Problems solved by technology

However, simply increasing the amount of polymer absorbent resin will lead to poor absorption performance for many times, and poor absorption performance of diapers under pressure. At the same time, the product will produce obvious graininess, which will affect the user experience.

If too much polymer absorbent resin is added to the ultra-thin core, it is also prone to the problem of polymer resin overflowing the product

[0006] 3) Designers only consider the surface soft touch of absorbent articles such as diapers, while ignoring its effect on product dryness

[0007] 4) Because the fine denier fiber is easy to bring water on the surface, which leads to the phenomenon that the surface is not dry enough, so although the fine denier fiber can bring excellent smoothness, the surface layer often does not use fine denier fiber, so the current diapers The skin affinity of the surface layer of the product needs to be further improved

[0008] Therefore, the performances of existing absorbent articles such as paper diapers need to be further improved.
