Technical Field

The invention relates to a composite material for a bottom layer of an anti-galactorrhea pad, belonging to the technical field of composite non-woven materials.

Background

The anti-galactorrhea pad is an essential daily article for controlling galactorrhea during female lactation, and is generally divided into four parts, namely a surface layer, a diversion layer, an absorption core body and a bottom layer, wherein the layers are bonded together by spraying glue, and the bottom layer is attached with gum and release paper. The bottom layer plays a crucial role in the structure of the whole anti-galactorrhea pad, and has great influence on preventing the penetration of the latex and improving the wearing comfort.

The conventional spill-proof breast pad bottom layer material in the market and research is a polyethylene film, but the air permeability is poor; even though some of the spill proof pad chassis layers use nonwoven materials for improved breathability, they have poor permeation resistance and low hydrostatic pressure resistance. Therefore, there is much room for improvement in the underlying material.
