摘要
假捻器是多孔氨纶丝生产过程中最重要的一个元器件,其通过空气喷嘴产生的涡流对氨纶丝束进行假捻,将多根单丝抱合在一起,形成最后的多孔氨纶丝。文章介绍了两种假捻器的结构,重点研究了其在实际生产中对氨纶丝性能的影响。研究结果表明:新型陶瓷结构的假捻器可以使氨纶丝束的抱合力更大、稳定性更好,并改善丝卷退绕稳定性,同时有利于提升氨纶丝的断裂强度和断裂伸长率。
The false twister is the most important component in the production process of multiwire spandex.It holds multiple single filaments together through the vortex generated by the air nozzle,and forms the final multiwire spandex.This paper introduces the structure of two false twisters and focuses on the influence of these structures on their performance in production.The results show that the false twister of the new ceramic structure can make the binding force stronger and more stable,improve the stability of the spandex unwinding,and improve the fracture strength and elongation of the spandex.
