Woven fabric made of shape memory polymer

A woven fabric of shape memory polymer which is formed by weaving blended yarns of shape memory polymer fibers and ordinary natural or synthetic fibers wherein said shape memory polymer fibers are made of a polyurethane elastomer having a shape memory property wherein the elastomer undergoes changes in an elastic modulus around a glass transition point higher than about 40.degree. C., the elastomer becoming rubbery at temperatures higher than the glass transition point and becoming glassy at a temperature lower than the glass transition point, and with which property a deformed shaped can be set in the woven fabric by cooling the woven fabric as deformed to a temperature lower than the glass transition point after making the elastomer memorize a basic shape, the basic shape being recovered by heating the woven fabric to a temperature higher than the glass transition point.

A woven fabric of shape memory polymer which is formed by weaving yarns of shape memory polymer fibers alone or by weaving said yarns and yarns of ordinary natural or synthetic fibers wherein the yarns or fibers of the shape memory polymer have a glass transition point lower than normal temperature and the shape of the fabric is set at a temperature higher than normal temperature.

A woven fabric of shape memory polymer which is formed by weaving yarns of shape memory polymer fibers alone or by weaving said yarns and yarns of ordinary natural or synthetic fibers wherein the yarns or fibers of the shape memory polymer have a glass transition point lower than normal temperature and the shape of the fabric is set at a temperature approximate to the temperature at which said polymer begins to flow.
