A kind of non-woven fabric for hygienic products, manufacturing method and application thereof

Abstract

The invention discloses a non-woven fabric for hygiene products, which comprises a first layer of non-woven fabric and a second layer of non-woven fabric, the first layer of non-woven fabric is made of thermoplastic fibers through direct laying and carding, and the fiber orientation is Horizontal direction; the second layer of non-woven fabric is formed by crimping and carding thermoplastic fibers, the fiber fineness is smaller than the fiber fineness of the first layer of non-woven fabric, and the orientation of the crimped fibers in the vertical direction; the non-woven fabric is provided with X There are intersecting prismatic stripes, hemispherical protrusions are arranged at the protruding and intersecting parts of the prismatic stripes, and a plurality of small holes are arranged at the concave and intersecting parts of the prismatic stripes. The non-woven fabric for sanitary products provided by the present invention has the advantages of fast urine absorption speed, less slippage and back seepage, and large absorption area, and can be applied to the field of sanitary products, such as baby diapers, pull-up pants, women's Use sanitary napkins, menstrual pants, adult diapers and incontinence pants.

Description

technical field [0001] The invention belongs to the technical field of non-woven fabric production, and in particular relates to a non-woven fabric for hygiene products, a manufacturing method and an application thereof. Background technique [0002] Disposable hygiene products such as baby diapers, pull-up pants, and sanitary napkins for women currently on the market are mostly made of multi-layer structures such as surface non-woven fabrics combined with internal water-absorbing resin layers and bottom leak-proof layers. The surface layer in direct contact with the skin is required to quickly guide the urine into the internal water-absorbing resin layer when the urine suddenly occurs, without leaving any liquid, and when the activity is under pressure from the human body, the urine does not seep back, keeping the surface dry, and creating a new environment for the human skin. Comfortable and good "microclimate" environment. [0003] The application number is CN20118006603...

AI Technical Summary

Problems solved by technology

However, since the direction of the ridges and valleys is only parallel to the length direction, the urine cannot spread laterally, and it is easy to increase the amount of slippage and back seepage.
