PURPOSE:To obtain the subject stretchable belt, closely adhered to the body and useful for belts, etc., for fixing waists without loosening in repeated use, by sewing a specific shape memorizing alloy thin belt exhibiting hyperelasticity characteristics in a fabric. CONSTITUTION:The objective belt obtained by sewing an Ni-Ti based shape memorizing alloy thin belt capable of exhibiting hyperelasticity in a fabric. Furthermore, an alloy prepared by cold working an Ni-Ti alloy containing 50.3-51.0atomic% Ni and heat-treating the resultant alloy at 400-500 deg.C for 30min-2hr is preferably used as the above-mentioned alloy. |
