Absorbent product for preventing side leakage and front and rear leakage and preparation method thereof

Abstract

The invention relates to the technical field of absorption supplies, in particular to an absorption supply for preventing side leakage, front leakage and back leakage and a manufacturing method thereof. Edge sealing bonding areas (5) and end sealing bonding areas (6) are arranged between a liquid permeating top piece (1) and liquid non-permeating side leakage preventing pieces (2). The edge sealing bonding areas (5) are continuous glue spraying glue lines, hot melt glue can be extruded to permeate to the liquid permeating top piece (1) to the maximum extent, a water repelling blocking layer is formed, and therefore the absorption supply has the side leakage preventing effect. The end sealing bonding areas (6) are discontinuous glue spraying glue lines, the discontinuous glue spraying glue lines are overlapped with the glue lines of the edge sealing bonding areas (5) in the longitudinal direction, seamless bonding of the ends of the absorption supply is achieved, and therefore absorption supply has the front leakage and back leakage preventing effect. The unique omega glue spraying mode is adopted in the edge sealing bonding areas (5) and the end sealing bonding areas (6), the process is easy to implement, safe and reliable, the side leakage, front leakage and back leakage of the absorption supply can be effectively avoided, and the application range is wide.

Description

technical field [0001] The invention relates to the technical field of absorbent articles, in particular to an absorbent article for preventing side leakage and front and rear leakage and a preparation method thereof. Background technique [0002] Traditional disposable absorbent articles mainly include a liquid-permeable top sheet, a liquid-impermeable side leakage prevention sheet, a liquid-impermeable bottom sheet, and an absorbent layer arranged between the liquid-permeable top sheet and the liquid-impermeable bottom sheet; The liquid top sheet and the liquid-impermeable anti-side leakage sheet are bonded by scraping glue, but the amount of glue used in the scraping glue method is relatively large, but the bonding strength is not enough, and it is easy to produce granular particles during the production process. Colloidal particles, resulting in defective products. At the same time, since the squeegee is only coated on the surface of the non-woven material and cannot pe...

[0002] Traditional disposable absorbent articles mainly include a liquid-permeable top sheet, a liquid-impermeable side leakage prevention sheet, a liquid-impermeable bottom sheet, and an absorbent layer arranged between the liquid-permeable top sheet and the liquid-impermeable bottom sheet; The liquid top sheet and the liquid-impermeable anti-side leakage sheet are bonded by scraping glue, but the amount of glue used in the scraping glue method is relatively large, but the bonding strength is not enough, and it is easy to produce granular particles during the production process. Colloidal particles, resulting in defective products

At the same time, since the squeegee is only coated on the surface of the non-woven material and cannot penetrate into the fiber net, the liquid will spread to both sides and both ends with the liquid-permeable top sheet, which is prone to side leakage and front and rear leakage.
