摘要
为了了解木棉与棉混纺转杯纱的捻度变化情况及强伸性能与捻度的关系,对木棉/棉50/50 36.5tex混纺转杯纱捻度随时间的变化情况、强力、断裂伸长率随捻度的变化情况进行了测试分析。结果表明,木棉棉混纺转杯纱具有退捻现象,捻度随放置时间增长而变小;强力随捻系数的增大而先增大后降低,捻系数为480时强力达到最大;断裂伸长率随捻度增大而不断增大。
To discuss twist change and relation between elongation ＆ twist of java cotton and cotton blended rotor yarn, change condition, strength, breaking elongation of java cotton / cotton 50/50 36.5 tex blended rotor yarn were tested. The test shows that java cotton cotton blended rotor yarn has detwisting, the twist is reduced with the increasing of time, strength is first increased then reduced with the increasing of twist factor, strength is the biggest when twist factor is 480, breaking elongation is reduced with the increasing of twist.
