精梳涤纶纤维含量对28 tex针织纱线性能影响研究

Study on the effect of content of combed polyester fiber on the properties of 28 tex knitting yarn

针对涤纶纤维在市场的使用占比越来越高,但涤纶纱线的品质有待提高。为了开发高品质涤纶针织纱,同时减少生产成本,生产出更具有特色化、差异化的纱线,文章采用紧密纺纺纱工艺,纺制28 tex针织用纱,试纺并对比精梳涤纶纤维含量对纱线条干均匀度、毛羽H值和强力拉伸等性能的影响。实验结果显示:精梳涤纶纤维比重在60%~70%时的纱线条干均匀度、纱疵、毛羽H值及拉伸性能等质量指标,与采用全精梳涤纶纤维生产的纱线差别不大,在实际生产过程中可以考虑选择此精梳涤纶纤维含量,以减少生产成本、增加经济效益。

In recent years,the proportion of polyester fibers in the market is increasing,but the quality of polyester yarn is yet to be improved.To develop high-quality polyester knitting yarn,reduce production costs,and produce more chracteristic and differentiated yarn,in this paper,28 tex knitting yarn is spun by compact spinning,and the effects of the content of combed polyester fiber on yarn evenness,hairiness H value,tensile strength and other properties are compared.The experimental results show that the yarn evenness,yarn defect,hairiness H value,tensile strength and other properties of yarns with a content of combed polyester fiber of 60%~70%have little difference from those of yarns made entirely of combed polyester fiber.In the actual production process,this content of combed polyester fiber can be considered to lower production costs and increase economic benefits.
