Absorption core body of ultrathin belt flow conducting groove

Abstract

The invention discloses an absorption core body of an ultrathin belt flow conducting groove. The core body comprises a core body main body. The core body main body is formed by upper layer non-woven fabrics, a surface layer glue scrapping layer, an upper layer continuous or interrupted strip-shaped polymer absorbent material layer, a first structural adhesive layer, a second structural adhesive layer, a lower layer continuous or interrupted strip-shaped polymer absorbent material layer, a lower layer glue scrapping layer and lower layer non-woven fabrics. The bottoms of the upper layer non-woven fabrics are adhered to the top of the upper layer continuous or interrupted strip-shaped polymer absorbent material layer through the face layer glue scrapping layer. The bottom of the upper layercontinuous or interrupted strip-shaped polymer absorbent material layer is adhered to the top of the lower layer continuous or interrupted strip-shaped polymer absorbent material layer through the first structural adhesive layer and the second structural adhesive layer. The bottom of the lower layer continuous or interrupted strip-shaped polymer absorbent material layer is adhered to the top of the lower layer non-woven fabrics through the lower layer glue scrapping layer. The absorption core body is simple in structure, proper in design and convenient to install and use.

Description

technical field [0001] The invention relates to sanitary products, in particular to an ultra-thin absorbent core with a flow guide groove. Background technique [0002] Traditional sanitary napkins and baby diapers have two types of core structure: one structure is made of wood fluff pulp and polymer (SAP) mixture (no glue in the mixture) and then covered with non-woven fabric, and the other is The disadvantages are that the structure of the product is very thick, it becomes thicker after absorbing water, and it is easy to form a lump, which makes it uncomfortable to use. Another structure adopts the upper layer non-woven fabric + polymer (SAP) + fluffy non-woven fabric + polymer (SAP) + lower layer non-woven fabric superimposed and compounded and then cut. When producing sanitary napkins and baby diapers , The polymer (SAP) in the core product leaks very seriously, resulting in waste of raw materials.

[0002] Traditional sanitary napkins and baby diapers have two types of core structure: one structure is made of wood fluff pulp and polymer (SAP) mixture (no glue in the mixture) and then covered with non-woven fabric, and the other is The disadvantage is that the product structure is very thick, it will be thicker after absorbing water, and it is easy to form a ball, so there is no comfort when using it

Another structure adopts upper layer non-woven fabric + polymer (SAP) + fluffy non-woven fabric + polymer (SAP) + lower layer non-woven fabric to be superimposed and compounded and then cut. When producing sanitary napkins and baby diapers , the polymer (SAP) in the core product leaks very seriously, resulting in waste of raw materials
