US 2017/0128275 A1 · METHOD FOR MANUFACTURING ABSORBENT ARTICLE

Abstract

A method for manufacturing an absorbent article including a liquid permeable layer, a liquid impermeable layer, and an absorbent layer, includes a step for forming a functional composition by mixing water-disintegrable microcapsules containing a volatile functional component with a solvent capable of keeping the functional component as contained in the microcapsules, a step for coating the functional composition on at least a portion of a surface of a layer to be coated to form a functional composition-coated region on the surface to be coated, and a step for stacking the liquid permeable layer, and the absorbent layer and the liquid impermeable layer with an adhesive-coated region coated with an adhesive interposed therebetween.

Dependent claims

A method of producing an absorbent article including a liquid-permeable layer, a liquid-impermeable layer and an absorbing layer between the liquid-permeable layer and liquid-impermeable layer, including the steps of:

forming a functional composition by mixing water-disintegratable microcapsules encapsulating a volatile functional component and a solvent capable of holding the functional component encapsulated in the microcapsules;
forming a functional composition-coated region on a coating surface of a layer to be coated by coating the functional composition onto at least a portion of the coating surface of the layer to be coated;
and
stacking the liquid-permeable layer, the absorbing layer and the liquid-impermeable layer sandwiching an adhesive-coated region that is coated with an adhesive.
