Technical Field

The invention relates to the technical field of feminine hygiene products, in particular to a composite core body for absorption.

Background

The composite core body is an absorptive substance, and the main material is cotton, non-woven fabric, paper pulp or high molecular polymer formed by the composite of the above materials and high molecular polymer composite paper. The water absorption of high molecular in the inner core of the prior sanitary towel is adhered to a straight non-woven fabric layer through composite glue. The water-absorbing material is generally a polymer resin, but the polymer resins have poor adhesion to each other, and once a large amount of water has been absorbed, the polymer resin moves with the water flow. When a human body is used, the human body is not horizontally placed, so that the diaper absorbs water in a part of the area to be larger after being used for a period of time, and the water absorption of the whole diaper is deteriorated, namely, the water absorption of the part without the water absorption is deteriorated because the water absorption starts to flow.

Disclosure of Invention

The invention aims to provide a 3D composite core body for a sanitary product, which improves the effective gluing area of water absorption by arranging non-woven fabrics with a three-dimensional containing area so as to reduce the thickness of the water absorption core.

The technical purpose of the invention is realized by the following technical scheme: a 3D composite core for a hygiene article, comprising: dustless paper, absorb water layer and parcel are outside water conservancy diversion non-woven fabrics, the layer that absorbs water set up in two-layerly between the dustless paper, the layer that absorbs water including the polymer absorb water quality and non-woven fabrics, the non-woven fabrics surface form three-dimensional accommodation area, the polymer absorb water quality fill at least in three-dimensional accommodation area.

Preferably, the surface of the non-woven fabric is provided with wave-shaped folds, and the three-dimensional accommodating area is an area formed at the concave part of the wave-shaped folds on the surface of the non-woven fabric.

In a preferred embodiment of the present invention, the grammage of the high molecular water-absorbing material in the three-dimensional housing zone is greater than one-half of the total grammage of the high molecular water-absorbing material.

Preferably, the distance between the wave crest or the wave trough of the non-woven fabric and the dust-free paper is not more than 2-5 cm.

Preferably, the thickness of the nonwoven fabric is more than twice the thickness of the dust-free paper.

In the present invention, the water absorbent is preferably a polymeric water absorbent resin.

Preferably, the surface of the non-woven fabric is provided with a glue layer, and the glue layer is glued with the surface of the high polymer water absorption material.

Preferably, a water locking layer is arranged between the water absorption layer and the dust-free paper, and the water locking layer is made of high-molecular water-absorbent resin mixed wood pulp.

In conclusion, the invention has the following beneficial effects:

the invention changes the storage space of the water absorption quality by utilizing the wavy folded non-woven fabric, fundamentally solves the problem that the water absorption quality is easy to move, and ensures that the uniform water absorption quality is contained in each unit area of the whole sanitary towel, thereby improving the water absorption performance of the whole sanitary towel and prolonging the service life.

And because the non-woven fabric is in a wave-shaped fold shape, the physical elasticity of the non-woven fabric is enhanced, so that the whole inner core has better elasticity, and the comfort is improved.
