摘要
Abstract
In order to study the effects of heat treatment temperature,time and medium on the NEDDP/PBT parallel composite filament,the curling properties,mechanical properties and elastic properties of the NEDDP/PBT parallel composite filament were tested by using a fiber curling elasticity instrument and an XN-1A nylon e-longation and elasticity tester.The results show that as the heat treatment time increases and the temperature ri-ses,the curling rate,curling recovery rate,and curling elasticity rate of the NEDDP/PBT parallel composite fila-ment will increase and stabilize.Other conditions being the same,the filament with wet heat treatment has better curling rate,curling recovery rate and curling elasticity rate than the filament with dry heat treatment.As the heat treatment time increases and the temperature rises,the elongation at break of the filament increases and the breaking strength decreases.The elongation at break of the filament increases from 40.77%to 99.52%,and the breaking strength decreases from 137.63 cN to 116.37 cN.Other conditions being the same,the filament with wet heat treatment has a larger elongation at break and a smaller breaking strength than the filament with dry heat treatment.As the heat treatment time increases and the temperature rises,the elastic recovery rate and plas-tic deformation rate of the filament increase slightly.The elastic recovery rate is around 91.5%and the plastic deformation rate is around 3%.Other conditions being the same,the elastic recovery rate of the filament with wet heat treatment is similar to that of the filament with dry heat treatment,but the plastic deformation rate of the filament with wet heat treatment is slightly larger.关键词
