摘　　要：选用44.4dtex和77.8dtex两种规格的氨纶长丝在经过改造的转杯纺纱机上纺制棉氨复合纱,设计了5种成纱捻度,测试分析了设计捻度对转杯纺棉氨复合纱结构和性能的影响情况。结果表明,在相同捻系数条件下棉氨复合纱较纯棉转杯纱条干均匀,表面光洁,断裂强力和断裂伸长率也较大;随着捻系数的增加,棉氨复合纱断裂强力的变化趋势是先增大后减小,断裂伸长率则呈增大趋势,但加捻效率下降。Spinning cotton polyurethane complex yarn in reformed rotor spinning machine with 44.4 dtex and 77.8 dtex polyurethane filaments, five twist is designed, and influence on structure and performance of cotton polyurethane complex yarn of design twist is tested. The test shows —— in the condition of same twist factor, cotton polyurethane complex yarn has better evenness than cotton rotor yarn, and has better surface finish, and high break strength & elongation at break which are increasing with twist factor. Change trend of cotton plyurethane strength is from high to low, elongation at break has increasing trend, but twisting efficiency is reduced.
