Abstract

The invention belongs to the technical field of daily chemicals, and in particular relates to a hot-air cloth for diapers and a preparation method thereof. In the product that the present invention develops, comprise polypropylene fiber, graphene oxide and polyethylene resin; Described graphene oxide is dispersed to form monolithic layer structure, and is bonded with polypropylene fiber by polyethylene resin; Described polypropylene fiber and The mass ratio of graphene oxide is 3:1-5:1; the amount of polyethylene resin is 5-10% of the mass of graphene oxide. During the preparation, the graphene oxide and polyethylene nanoparticles were first mixed with heat-insulating ball mill to obtain a ball mill, and then mixed and soaked with saturated sodium bicarbonate solution to obtain modified graphene oxide; then polypropylene fiber and modified The graphene oxide is evenly mixed, loosened, combed, and then shaped by hot air at a temperature of 120-150°C, cooled, and discharged to obtain a hot-air cloth for diapers. The product obtained by the invention not only has excellent bulkiness, but also can effectively prevent water seepage back.

Description

technical field [0001] The invention belongs to the technical field of daily chemicals, and in particular relates to a hot-air cloth for diapers and a preparation method thereof. Background technique [0002] Diapers are a liquid absorption and control system composed of multi-layer non-woven materials. According to their specific structure, they can be divided into several main components: surface layer, absorbent core layer, bottom film, partition and flow guide layer. The principle of liquid absorption of diapers is to use the functional collocation of each layer of non-woven materials to meet the process of gradual liquid absorption. When artificial urine is poured into a diaper sample, the urine will first contact the surface surface material, and spread horizontally and vertically along the nonwoven material, then the liquid will penetrate the surface layer and flow into the guide layer material, and finally be absorbed by the absorbent core. The water-absorbing polym...
