Absorbing core for absorptive article and manufacturing process of absorbing core

Abstract

The invention discloses an absorbing core for an absorptive article and a manufacturing process of the absorbing core. The absorbing core comprises an upper wrapping layer, a middle absorbing layer, a lower wrapping layer and a viscose layer, and the middle absorbing layer comprises a middle fiber layer, a first absorbing core layer positioned between the upper surface of the middle fiber layer and the upper wrapping layer, and a second absorbing core layer positioned between the lower surface of the middle fiber layer and the lower wrapping layer; the first absorbing core layer comprises a plurality of first absorbing core bodies distributed along the width of an absorptive article core at intervals, and the second absorbing layer comprises a plurality of second absorbing core bodies distributed along the width direction of the absorptive article core at intervals and corresponding to the first absorbing core bodies; the viscose layer comprises first viscose bodies positioned between each two first absorbing core bodies and used for bonding the upper wrapping layer with the middle fiber layer and second viscose bodies positioned between each two second absorbing core bodies and used for bonding the lower wrapping layer with the middle fiber layer.

Description

technical field [0001] The invention relates to the field of sanitary products, in particular to an absorbent core used for absorbent articles and a manufacturing process thereof. Background technique [0002] Diapers are a commonly used sanitary product. Generally speaking, diapers are composed of three main parts: cover layer, absorbent core and base fabric. The surface coating layer can also be called a coating layer or a water-permeable surface layer. The coating layer is close to the user's body, which can promote the rapid penetration of urine and effectively prevent back seepage, so that the surface layer of the diaper can be kept dry. At present, the covering layer of diapers in the domestic market is basically a non-woven surface layer. The breathable non-woven fabric can improve the air permeability inside the diaper, and the water vapor can circulate outside the diaper, and the moisture and heat can be discharged in time, effectively reducing the air permeability...

AI Technical Summary

Problems solved by technology

This structure has the following defects: 1. The full-spray glue spraying method wastes the amount of glue, resulting in a strong smell of glue, which reduces user experience and satisfaction; 2. The polymer water-absorbing resin is sprinkled on the middle fiber layer, and the distribution is scattered, and After being covered by viscose, the effect of fast liquid absorption cannot be achieved, the urine diversion speed is slow, and the absorption and diffusion are slow; 3. Increased production costs
