STRETCH STRUCTURE FOR DISPOSABLE WEARABLE ARTICLE, AND FORMATION METHOD FOR STRETCH STRUCTURE FOR DISPOSABLE WEARABLE ARTICLE
Document Type and Number:
WIPO Patent Application WO/2018/061288
Kind Code:
A1
Abstract:
The present invention addresses the problem of simplifying the production of a stretch structure that comprises an elastic member. The present invention addresses said problem by means of a stretch structure that comprises an elastic member (19) that is provided between a first sheet layer (12S) and a second sheet layer (12H), wherein, from one stretch-direction end of the stretch structure to the other, there are at least three alternating stretch regions (22) and non-stretch regions (21), and there is a stretch region (22) at both stretch-direction ends. Both stretch-direction end parts of the stretch regions (22) have a hot-melt adhesive (71) adhesion region at which the elastic member (19) has been adhered to the first sheet layer (12S) and the second sheet layer (12H). In an expanded state, the intervals (71d) between adhesion regions that are adjacent in the stretch direction are all the same, and the stretch-direction lengths (71w) of the adhesion regions that are positioned at non-stretch region (21) side end parts of the stretch regions (22) are all twice the stretch-direction length (71w) of the adhesion regions that are positioned at either stretch-direction end part of the stretch structure.
