Is the absorbent of the sanitary napkin used for women the same as that of the diaper used for babies?

Lester

The two materials are not exactly the same, mainly in the proportional distribution of different materials.Women use sanitary napkins to absorb less, mainly to absorb sticky menstrual blood, while diapers absorb more water (non-sticky). It mainly includes the following two materials (what is mentioned here is only absorbent materials): wood pulp fiber, polymer water absorbent.First, give you a brief introduction: 1. Wood pulp: Wood fiber uniquely has a large number of irregular gaps. These natural voids are very hydrophilic and can hold more water. 2. Polymer absorbent resin: High absorbent resin is a new functional polymer.Its water absorption capacity is hundreds to thousands of times heavier than itself, and it has good water preservation performance. Once the water absorption expands into a gel, it is difficult to separate the water. For sanitary napkins, the absorption ability of wood pulp is higher, accounting for 70-80% of the absorption amount of sanitary napkins.Because the polymer water absorbent is not suitable to absorb the viscous liquid and is expensive, it accounts for 20-30% of the sanitary napkin absorptive materials.
