摘要
Abstract
To compare the elasticity and durability of NEDDP/PBT juxtaposed composite filaments with spandex,an XN-1A spandex elasticity tester was employed.Based on the preliminary experimental results,it was found that it was unreasonable to select the same specified elongation for both fibers.Therefore,two fibers with each 30%and 50%of elongation at break as specified elongations were adopted,and the elasticity and elas-tic durability of spandex and NEDP/PBT juxtaposed composite filaments in cyclic stretching were compared and analyzed.The results showed that spandex exhibited higher elastic recovery rates while NEDDP/PBT juxtaposed composite filaments showed lower plastic deformation rates.With increasing specified elongation and cycle num-bers,both fibers displayed declining elastic recovery rates and rising plastic deformation rates.Hysteresis loop a-nalysis confirmed that both were incomplete elastic bodies,but NEDDP/PBT juxtaposed composite filaments demonstrated superior elastic durability during cyclic stretching.关键词
