[Common textile manual] Women's sanitary napkin

Overview

Women's health care supplies. Women's sanitary napkins are the earliest and most used type of women's products. The early hygienic forms were rectangular. At present, most of them are rectangular products with wings, and there are a wide variety of products. Various thicknesses, lengths, and products with various other functions are designed according to the occasion and time of use. Women's sanitary napkins absorb mainly blood, and the adhesion of the blood is much greater than that of urine. Therefore, the surface layer of the sanitary napkin is generally required to be made of mechanically perforated or hydroentangled materials so as to enhance its permeability and diffusion. The layer adopts a fiber network structure with a strong diffusion capability and a composite method. In addition, since the flow rate of menstrual blood is slower than that of urine, the amount of menstrual blood is also less than that of urine, and menstrual blood is sticky, the amount of SAP used in the core layer can be reduced accordingly to increase the flexibility of the sanitary napkin.
