High-absorbency baby paper diaper and making technology thereof

Abstract

The invention discloses a high-absorbency baby diaper, which comprises a surface structure, an absorbent core structure, a bottom layer structure, a closed structure and an adhesive structure, the surface structure comprises a surface non-woven fabric, and the absorption core structure comprises a composite core, Core-spun non-woven fabric and a flow-guiding layer fixed in the middle of the outer side of the core-spun non-woven fabric, the underlying structure includes a bottom non-woven fabric and a water-proof membrane bonded to the inner side of the bottom non-woven fabric, and the closed structure includes a front waist tape , leg elastic, three-dimensional protection, three-dimensional protection elastic, left and right Velcro and elastic waist, the absorbent core structure is fixed on the underlying structure, the surface layer of non-woven fabric is covered on the absorbent core structure, and the diversion layer is set on Between the surface layer non-woven fabric and the core-spun non-woven fabric, both sides of the surface layer non-woven fabric are fixed on the underlying structure, and there is an expansion gap between the two sides of the absorbent core structure and the surface layer non-woven fabric. The invention can increase the expansion coefficient of the diaper, thereby prolonging the use time of the diaper and improving the wearing comfort of the baby.

Description

technical field [0001] The invention belongs to products for infants and children, in particular to a high-absorbency baby diaper and a manufacturing process thereof. Background technique [0002] With the continuous improvement of living standards, adults often hope to give the best things to children. Therefore, people have higher and higher requirements for infant products (such as baby diapers, etc.); It is the surface non-woven fabric that directly wraps the absorbent core. When the absorbent core expands to a certain extent, it will not be able to continue to expand because of the surface non-woven fabric. If it is not replaced in time, it will affect the comfort of the baby. Therefore, in order to prolong the use time of baby diapers and improve the wearing comfort of babies, it is necessary to study how to increase the expansion coefficient of baby diapers. Contents of the invention [0003] In order to solve the above-mentioned defects and deficiencies in the pri...
