玄武岩棉不锈钢长丝复合纱的制备及性能研究OACSTPCD

To explore the property of basalt cotton stainless steel filament composite yarns prepared and based on the spreading apparatus,the basalt cotton stainless steel filament composite yarns were prepared by using multi-axis composite spinning technology.The twist,hairiness number,yarn evenness,and mechanical property of the spreading and non-spreading composite yarns were tested and compared.The results showed that,compared to non-spreading structural composite yarns,the average twist of spreading structural composite yarns was reduced by 6.33%and the unevenness of twist was reduced.After spreading,basalt single yarn width was increased,which was more beneficial to cover the cotton fiber on the surface of core yarn.The 3 mm hairiness number of the spreading structural composite yarns was reduced by 39.18%,and CV value of fragment length weight was reduced by 1.53 percentage points.Moreover,the breaking strength and breaking elongation rate were increased by 13.49%and 31.37%respectively.It is considered that the property of composite yarns can be significantly improved by adjusting the yarn structure and using spreading structure.Meanwhile,combining with multifunctional new textile materials,high-quality and high-performance functional composite yarns can be prepared.
