Sanitary napkin

Abstract

The invention provides a sanitary napkin. The sanitary napkin comprises a liquid absorption layer, a liquid guide layer, an absorption core layer and a hydrophobic bottom film layer, which are compounded in sequence, wherein the liquid absorption layer is formed by mixing 25%-35% of corn starch and 65%-75% of cotton fibers; the liquid guide layer is a flow guide line which is arranged between the liquid absorption layer and the absorption core layer in a spiral shape; the absorption core layer comprises one coarse fiber layer which is laid through a cotton laying machine, a fine fiber layer which is laid above the coarse fiber layer through the cotton laying machine, and a macromolecular resin layer which is arranged on an upper surface of the fine fiber layer through a macromolecular material blowing mechanism; and the thickness of the coarse fiber layer is greater than that of the fine fiber layer. The sanitary napkin is convenient to machine, can be used for rapidly adsorbing and is not easy to permeate reversely and leak.

Description

technical field [0001] The present invention relates to a sanitary napkin. Background technique [0002] Sanitary napkins are substances that absorb liquids and belong to women's special care products. The main material of sanitary napkins is cotton-like pulp and polymer absorbents, which are used to absorb the menstrual blood that flows out of the vagina during women's menstrual cramps, so as not to stain the clothes. The surface of the sanitary napkin is in direct contact with the human body to absorb body fluids, so the performance of the surface material directly affects the user experience. The surface layer of the existing ordinary sanitary napkins in contact with the human skin is mostly ordinary fabrics such as synthetic fibers and non-woven fabrics. Due to the limited speed of absorbing body fluids in the surface fabrics, the menstrual blood diffuses on the surface layer of the sanitary napkin and stays for a long time. Often accompanied by symptoms such as dampne...

Problems solved by technology

The surface layer of the existing ordinary sanitary napkins in contact with the human skin is mostly ordinary fabrics such as synthetic fibers and non-woven fabrics. Due to the limited speed of absorbing body fluids in the surface fabrics, the menstrual blood diffuses on the surface layer of the sanitary napkin and stays for a long time. Often accompanied by symptoms such as dampness and itching, it is easy to wrinkle and has poor comfort. Moreover, the liquid-absorbing layer of ordinary sanitary napkins is oxidized by hydrogen peroxide, which is harmful to human skin.
