石墨烯改性涤纶/蓄热调温纤维/长绒棉混纺纱的制备与性能分析

Preparation and Performance of Graphene Modified Polyester/Outlast Fiber/Long Stapled Cotton Blended Yarn

文章采用石墨烯改性涤纶、蓄热调温纤维、长绒棉设计开发了混纺比为50/30/20、30/50/20、20/70/10的3种复合功能纱线,并对纱线的强力、拉伸性能、条干均匀度以及热学性能和抗菌性能进行测试分析。结果表明:蓄热调温纤维的静电现象会影响混纺纱的条干均匀度,并且其含量的增加会使混纺纱线的断裂强力降低;石墨烯改性涤纶所占质量分数的增加会造成混纺纱的韧性下降,同时混纺纱的热学性能和抗菌性能也会受到纤维不同混纺比的影响。

The paper uses graphene-modified polyester,outlast fiber,and long stapled cotton to design and develop three composite functional yarns with blending ratios of 50/30/20,30/50/20,and 20/70/10,and carries out researches on their strength,tensile properties,uniformity of the strands,and thermal and antimicrobial properties.The results indicated that the electrostatic phenomenon of the outlast fiber will affect the yarn evenness of the blended yarn,and the increase of the outlast fiber content will reduce the breaking strength of the blended yarn.The increase in the mass fraction of the graphene fiber will cause the toughness of the blended yarn to decrease,and the thermal and antibacterial properties of the blended yarn are also affected by the different blending ratios of the fibers.
