摘要
针对玄武岩纤维纱线在编织绳索过程中因磨损而导致绳索力学性能下降的问题,提出通过摩擦纺纱技术在玄武岩纤维表面包覆水溶性维纶纤维,减少绳索编织过程中玄武岩纤维受到的磨损,并在绳索编织成形后溶解外层维纶纤维,得到玄武岩编织绳索。通过控制原料喂入速度来调整玄武岩包芯纱的表层包覆效果。通过正交实验探究编织夹角、编织速度、编织节距对绳索力学性能的影响,优化绳索编织工艺;对编织绳进行结构表征和力学性能测试,分析编织速度对编织绳力学性能的影响。结果表明:以0.30 m/min的喂入速度制备的玄武岩包芯纱的包覆效果最好;通过正交实验得出编织速度对绳索力学性能影响最大,以11.14 m/h的低编织速度制备的绳索水溶后的结构最均匀,在扭结、弯曲等条件下均表现出良好的力学性能。
In response to the degradation of the mechanical properties of basalt fiber yarn due to abrasion during the process of rope weaving,it is proposed to coat water-soluble whalen fibers on the surface of basalt yarns by using friction spinning technology to reduce wear and tear of the basalt fiber during the process of rope weaving and after the rope is woven into shape.The outer layer of vinylon fibers is dissolved to obtain a basalt woven rope,and to adjust the basalt core-spun yarn surface coating effect by controlling the raw material feeding speed.It is also proposed to explore the weaving angle,the weaving speed and weaving pitch on the mechanical property of the rope through orthogonal experiments and then optimize the rope weaving process;to perform structural characterization and mechanical properties test of woven ropes,then analyze the influence of weaving speed on the mechanical properties of woven ropes.The results show that the basalt core-spun yarn prepared at a feeding speed of 0.30 m/min has the best coating effect;it is concluded by the orthogonal experiments that the weaving speed has the greatest influence on the mechanical properties of ropes,and the structure of the rope pre-pared at the low weaving speed of 11.14 m/h is the most uniform after water solution and exhibits good mechanical properties under conditions such as knotting and bending.
