柔洁纺粘胶强捻纱及其织物性能

为更好地探究柔洁纺技术对粘胶强捻纱质量和其机织物服用性能的影响,对相同工艺参数下粘胶强捻柔洁纺纱线与环锭纺纱线的均匀度、毛羽、单纱强力、捻缩率和表观结构进行测试对比,同时分析了相同规格柔洁纺和环锭纺粘胶强捻纱织物的强伸性、顶破性能、撕破性能、透气透湿性、吸湿性、柔软性和抗起毛起球性能。结果表明:柔洁纺粘胶强捻纱的毛羽少,条干均匀,强力高,捻缩率低;相比环锭纺粘胶强捻纱织物,柔洁纺粘胶强捻纱机织物的强伸性、顶破性能、撕破性能、透气透湿性、柔软性和抗起毛起球性显著提高,但吸湿性有所降低;柔洁纺粘胶强捻纱具有柔顺、整洁、牢固等特点,其机织物的综合服用性能优于环锭纺。

Properties of soft-spun viscose hard-twist yarn and fabric thereof

In order to better explore the improvement of the viscose hard twist yarn and the wearability of its woven fabrics, yarn uniformity, hairiness, yarn strength, contraction rate and apparent structure of soft-spun and ring-spun viscose hard twist yarn were tested and compared under the same process parameters. The strength, bursting properties, tearing properties, air permeability, moisture permeability, softness and pilling resistance of the same specifications of soft-spun and ring-spun viscose fabrics were tested. The results show that the soft-spun viscose hard twist yarn has less hairiness, uniform strips, high strength and low contraction rate. Moreover, compared with the spun viscose fabrics, the soft-spun viscose woven fabric has significantly improved in tensile strength, bursting performance, tearing property, air permeability and moisture permeability, softness and pilling resistance, but the hygroscopicity is lowered. The soft-spun viscose hard twist yarn has the characteristics of smoothness, neatness and firmness, and the comprehensive wearability of the soft-spun fabric is superior to that of the ring-spun one.
