Embodiment Construction
[0024] The present invention will be further described in detail through specific embodiments below. However, those skilled in the art will understand that the following examples are only used to illustrate the present invention, and should not be considered as limiting the scope of the present invention.
[0025] refer to figure 1 , a diaper partition sizing manufacturing process, comprising the following steps:
[0026] a). Spray glue on the lower part of the core body by a glue spraying machine and glue it to the bottom film, wherein the glue sprayed in the front waist 001 area is greater than the glue sprayed in the crotch 003 area;
[0027] b). Glue is sprayed on the top of the core by a glue sprayer and glued to the hydrophilic non-woven fabric, wherein the amount of glue sprayed in the front waist 001 area is greater than the amount of glue sprayed in the crotch 003 area;
[0028] c). The hydrophilic non-woven fabric is sprayed with glue by a glue spraying machine and...

Abstract
The invention provides a diaper and a glueing process for producing the diaper. When a glue sprayer is used for spraying and laminating layers of the diaper, a front waist region, a back waist regionand a crotch region of the diaper are sprayed; and the amount of glue applied in the front waist region and the back waist region is larger than that in the crotch region. The diaper of the present invention increases the amount of glueing of the front waist region and the back waist region and reduces the amount of glueing of the crotch, so that the crotch portion of the diaper is more favorablefor the flow absorption of urine, and the front waist region and the back waist region of the diaper are able to better prevent leakage of urine. The diaper and glueing process for producing the diaper are primarily used in the field of baby products.
Description
technical field [0001] The invention relates to the field of hygienic products, in particular to a paper diaper and a manufacturing process for diapers and sizing in different regions. Background technique [0002] Diapers are disposable products that can be discarded after use. The existing diaper structure is mainly composed of five parts, which are arranged in sequence from the top layer to the bottom layer: surface layer, diversion layer, middle absorbent core layer, three-dimensional enclosure and back layer. The material used for the surface layer is usually two-component synthetic fiber air-through non-woven fabric, polypropylene hot-rolled cloth or spun-bonded non-woven fabric; the diversion layer mainly uses two-component synthetic fiber air-through non-woven fabric; the middle absorbent core layer is made of fluff pulp. Composed of super absorbent resin; water-repellent SMS with elastic bands for three-dimensional protection; the back layer is mainly PP breathable...
