Introductionraw Material Used In Sanitary Napkins

1. Introduction to Raw material used in sanitary napkins.

Sanitary napkin is an absorbent material, mainly made of high molecular polymer and high molecular polymer composite paper, made of cotton, non-woven fabric, pulp or a composite of the above materials. The raw material of cotton soft sanitary napkins is mainly polypropylene, and the raw material of pure cotton sanitary napkins is mainly pure cotton non-woven fabric.

In terms of structure, sanitary napkins are generally composed of three parts: the surface layer, the absorbent layer and the bottom layer. The layers are bonded with hot melt adhesive, and the back glue of sanitary napkins is generally made of impermeable material. The back glue is impermeable, which can keep the menstrual blood in the sanitary napkin, and is used to absorb the menstrual blood from the vagina when women's menstrual cramps come. Women's resistance is very poor during menstruation, and if they don't pay attention to care, it will cause various problems in the body.

2. Sanitary napkin materials and functional considerations

First, the surface layer should choose a funnel type of dry mesh surface. The surface is dry and the local skin will not suffer from moisture. The funnel-shaped design is better than the barrel-shaped design, and the infiltrated liquid is not easy to flow back.

Second, the middle layer should be breathable and contain a high-efficiency gelled layer. Sanitary napkins with a high-efficiency gelling layer can condense the infiltrated liquid into a jelly-like shape, which will not seep back after being pressed, and the surface will not feel sticky.

Third, the bottom layer should be made of breathable material, which can allow gaseous water molecules to pass through smoothly, so as to achieve the effect of timely discharging moisture, effectively reducing the effect of sanitary napkins and body discharging moisture, effectively reducing the The dampness and stuffiness between the sanitary napkin and the body keep you dry and fresh.

The design of the side of the sanitary napkin is mainly used to prevent side leakage, because it will be at an angle with the body of the sanitary napkin during use, and it is easier to rub against the groin. Therefore, sanitary napkins with soft sides are more popular among women.
