Abstract
The invention provides a laminated shape-retainable sheet which has such a sufficient shape retainability that a user can give a desired shape easily to the sheet, and requires no press working step for giving a curved shape, a core for a headwear brim using the same, a brim of a headwear, and a headwear. In the laminated shape-retainable sheet of the invention, shape-retainable sheets each comprising a thermoplastic resin and each having shape retainability in a monoaxial direction are laminated and bonded onto each other in such a manner that the monoaxial directions of adjacent sheets out of the shape-retainable sheets make a predetermined angle, in particular, 45 to 90 degrees.
Claims5
A brim of a headwear, comprising a core made of a laminated shape-retainable sheet, comprising
- at least two shape-retainable sheets each comprising a mono-axially drawn olefin resin sheet having a total draw ratio of 10 to 40 and a thickness of from 0.1 to 0.5 mm, each having shape retainability in a monoaxial direction, and in which plural nicks or folds are made at intervals of 5 mm or less substantially parallel to the axial direction having the shape retainability, and
- at least one low melting point resin film made of (i) an ethylene/vinyl acetate copolymer or (ii) a linear low density polyethylene resin,
- wherein the low melting point resin film is laminated between the shape-retainable sheets by being heated under pressure and being bonded onto the shape-retainable sheets in such a manner that the monoaxial directions of adjacent shape-retainable sheets make a predetermined angle and do not have any space between the shape-retainable sheets.
