Absorbing core body

Abstract

The invention relates to the field of disposable sanitary products, in particular to an absorbing core body. The absorbing core body comprises a body of an absorbing core and a coating layer with liquid permeability, wherein a layer of composite paper is attached to the body of the absorbing core; the inside of the coating layer is coated with the body of the absorbing core and the composite paper; the composite paper is formed by mixing 20 to 40 parts by weight of super absorbent polymer particles, 45 to 60 parts by weight of non-woven fabric fragments and 0 to 20 parts by weight of plastic film fragments.

Description

technical field [0001] The invention relates to the field of disposable sanitary products, in particular to an absorbent core. Background technique [0002] With the development of the economy and the improvement of people's living standards, people have more and more demands for disposable sanitary products. For example, when using disposable sanitary products in summer, they are tired of products that are heavy, poor in comfort, and inconvenient to carry. In the past, the absorbent core of disposable sanitary products was formed by impacting wood pulp, crushing it into fibers and mixing it with absorbent resin, and then covering it with toilet paper or non-woven fabric. Therefore, whether the absorbent core can guide, absorb, and store , The function of locking the liquid determines the quality of the product, so the wood pulp fiber or the absorbent resin will be added during the production of the product, and too much wood pulp fiber will make the product thick and hard, ...

[0002] With the development of the economy and the improvement of people's living standards, people have more and more demands for disposable sanitary products. For example, when using disposable sanitary products in summer, they are tired of products that are heavy, poor in comfort, and inconvenient to carry.

In the past, the absorbent core of disposable sanitary products was formed by impacting wood pulp, crushing it into fibers and mixing it with absorbent resin, and then covering it with toilet paper or non-woven fabric. Therefore, whether the absorbent core can guide, absorb, and store , The function of locking the liquid determines the quality of the product, so the wood pulp fiber or the absorbent resin will be added during the production of the product, and too much wood pulp fiber will make the product thick and hard, and the excessive increase of the absorbent resin will make the product After absorbing liquid and expanding, it will increase the probability of "gel blocking", and also increase the cost of materials

When the absorbent core of thin disposable sanitary products encounters liquid, its non-woven covering layer is easy to deform and rupture when exposed to temperature, and it is easy to precipitate wood pulp; and the absorbent core of thin disposable sanitary products When encountering liquid, there may be problems such as "gel blocking" caused by excessive water absorption of the water-absorbent resin
