Problems solved by technology

[0002] At present, the core body of hygiene products is mainly divided into two categories: wood pulp core body and composite core body: wood pulp core body is formed by mixing fluff pulp and polymer water-absorbing resin (SAP), without layering or partitioning, wood pulp core body The water absorption effect of the body is good, but because its structure is relatively loose, there is no adhesive added, and the fluff pulp and SAP cannot be fixed, so there will be lumps and faults during use; the composite core is made of dust-free paper, non-woven Composed of cloth and SAP, each layer of material i

Embodiment Construction

[0038] A glue-free needle-punched absorbent core, characterized in that the core comprises a surface layer of non-woven fabric, an intermediate layer and a bottom layer of non-woven fabric, the intermediate layer comprises at least one layer of cotton fiber, at least one layer of high In the water-absorbing resin particle layer, the core body is formed through at least one needling process.

[0039] A cotton fiber layer and a superabsorbent resin particle layer of the middle layer are formed by needle punching with the surface layer or the bottom non-woven fabric.

[0040] One layer of cotton fiber layer of the middle layer and the non-woven fabric of the surface layer or the bottom layer are formed by needling.

[0041] The needled top layer and bottom layer are connected through the cotton fiber layer.

[0042] The formation is formed by at least one needle-punching process, including laying a cotton fiber layer on the bottom non-woven fabric and sprinkling high water-absor...

Abstract

The invention relates to a gel-free needle punching absorption core. The core comprises a surface layer nonwoven layer, an intermediate layer and a bottom layer nonwoven layer, wherein the intermediate layer comprises one or more cotton fiber layers, and one or more high-water-absorption resin granule layers; and the core is formed through one or more needle punching working procedures. Through aneedle punching technology, bottom layer nonwovens and cotton gridding cloth are interwoven and combined, and a conventional composite core gelatinizing technology is not used, so that existence of chemical substances in products is reduced again, and the core does not contain a melt adhesive, and is environmental-friendly.

Description

technical field [0001] The present application relates to the field of personal hygiene products, in particular to a non-adhesive needle-punched absorbent core and a hygiene product containing the core. Background technique [0002] At present, the core body of hygiene products is mainly divided into two categories: wood pulp core body and composite core body: wood pulp core body is formed by mixing fluff pulp and polymer water-absorbing resin (SAP), without layering or partitioning, wood pulp core body The water absorption effect of the body is good, but because its structure is relatively loose, there is no adhesive added, and the fluff pulp and SAP cannot be fixed, so there will be lumps and faults during use; the composite core is made of dust-free paper, non-woven Composed of cloth and SAP, each layer of material is bonded with hot melt adhesive. The core contains a large amount of SAP to ensure the water absorption of the diaper. After absorbing water, the overall expa...
