| Summary |
Basic mechanical properties of heat shrinkage polyester fiber cloth (Dacron heat-shrink fabric) ,that has achieved the cloth - boat of getting on of one person of about 4kg in weight, is examined. Moreover, the relation between a heat contraction calorie and the contraction percentage used for the assembly is examined. As a result, the strength of warp direction is about 170 N/cm and that of weft direction is about 100 N/cm. The contraction percentage of warp direction is about 5% and the weft direction is about 1.5% under the condition of 120 centigrade and 1 minute.
