[0003] The absorbent core layer is the key structural part of the absorbent system of diapers. It is located between the diversion layer and the leak-proof bottom film in diapers. The quality of its absorption performance directly affects the quality of diapers. At present, the absorbent core layer of diapers is mainly made of toilet paper or non The woven material is made of a mixtur

Embodiment Construction

[0014] A diaper with an independently layered absorbent core material, including a surface layer, a diversion layer, an absorbent core layer and a bottom film, wherein the absorbent core layer is composed of a filter bag and the absorbent core material layered and filled in the filter bag; The filter bag used is made of upper non-woven fabric, middle layer of bamboo / cotton fiber blended fabric and lower layer of non-woven fabric which are heat-pressed and sealed around. Resin, fluff pulp is filled between the middle layer of bamboo / cotton fiber blended fabric and the lower layer of non-woven fabric.

[0015] Wherein the upper non-woven fabric is finished by a stiff finishing agent, and the lower non-woven fabric is finished by a hydrophobic finishing agent.

[0016] After the urine enters the absorbent core layer during use, part of the urine is first absorbed by the fluff pulp of the lower layer, and part of the urine is absorbed by the superabsorbent resin, which expands in ...

Abstract

The invention discloses a paper diaper with an independent layered absorption core material. The absorption core material is formed by layered placement of super-absorbent resin and fluff pulp through a fixable and detachable filter bag with a double-layer inner cavity structure. An operating principle of the paper diaper includes that since the fluff pulp is poor in moisture retention performance but better than the super-absorbent resin in liquid absorption capacity, urine entering the absorption core material is partially absorbed by the lower fluff pulp first and partially absorbed by the super-absorbent resin, the super-absorbent resin swells after liquid absorption and extrudes the lower fluff pulp due to stiffness of an upper nonwoven fabric of the filter bag, and then urine overflowing from the fluff pulp is absorbed by the super-absorbent resin, so that urine in the fluff pulp is greatly reduced by repeating of the process, a great moisture retention effect is achieved, and urine reverse osmosis is effectively prevented. Due to the detachable structure, the paper diaper is recyclable, thereby being more environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of diapers, in particular to a diaper with independently layered absorbent core materials. Background technique [0002] Diapers are commonly used daily necessities for babies, and are a general term for diapers, diapers, and pull-up pants. Dry diapers can keep babies sleeping peacefully all night. Because of their strong water absorption, they are commonly known as "diapers". Diapers generally consist of three main parts: a cover sheet, an absorbent core, and a backsheet. Its working principle is: first, the surface layer of the diaper receives urine and penetrates downward, and then the diversion layer receives the urine infiltrated from the surface layer, conducts and diffuses longitudinally along the diversion layer, and the fluff pulp passes the liquid through the action of the capillary. Rapid absorption and diffusion, and then the liquid in the pulp fiber is absorbed by the SAP, and the pulp returns...
