Title:
METHOD AND APPARATUS FOR MANUFACTURING ELASTIC SHEET, METHOD AND APPARATUS FOR MANUFACTURING STRETCHABLE COMPOSITE SHEET, AND STRETCHABLE COMPOSITE SHEET
Document Type and Number:
WIPO Patent Application WO/2019/151064
Kind Code:
A1
Abstract:
Provided are: a method and apparatus for manufacturing a highly permeable elastic sheet; a method and apparatus for manufacturing a highly gas-permeable stretchable composite sheet; and a highly gas-permeable stretchable composite sheet. An elastic resin material containing a thermoplastic elastic resin as a main component is melted by being heated to a temperature higher than a temperature range in which the elastic resin material is elastically deformed, the molten elastic resin material is discharged in a fibrous or linear form, the discharged elastic resin material (intermediate (2)) is applied in a net shape onto a cooling member (30), the applied elastic resin material is cooled by the cooling member (30) to the temperature region in which the elastic resin material is elastically deformed, and the applied elastic resin material is solidified to obtain an elastic sheet (3). The elastic sheet (3) and non-woven fabrics (4, 6) are stacked and joined to obtain a stretchable composite sheet (8).
