Method for imparting shape memory property to a fibrous sheet and a fibrous sheet product having shape memory property

摘要

A fibrous sheet (1) having the shape memory property which comprises a sheet made of natural fiber (2), and/or synthetic fiber (2) and a layer formed by applying a powder of shape memory polymer (3); e.g. urethane polymers, styrene-butadiene polymers, cristalline diene polymers, and norbernane polymers and a method of imparting the shape memory property which comprises applying a powder of shape memory polymer (3) to a desired part of a product of a sheet made of natural fiber (2) and/or synthetic fiber (2) by the aid of a resin adhesive (4), e.g. a highly viscous polyurethane adhesive dissolved in a solvent.
