摘要:

针对苎麻纤维刚度大、成纱毛羽过多、经典四组分嵌入纺操作不便等技术问题,采用简化嵌入纺组分、加捻成纱段增设海绵接触纱条装置,提出接触式简易嵌入纺的纺纱方法。分析了简易嵌入纺、干态接触式简易嵌入纺、湿态接触式简易嵌入纺的成纱机制,并改造传统环锭纺纱小样机进行实验。对比分析各种简易嵌入纺技术的成纱性能与品质。结果表明:与简易嵌入纺、干态接触式简易嵌入纺相比,采用湿态接触式简易嵌入纺技术,可在线柔化苎麻纤维,利于纤维间扭转抱合与弯曲包缠,纺制的纱线毛羽大幅降低,拉伸断裂强力较高,成纱品质好。

Abstract:

In order to solve the high rigidity and excessive hairiness of ramie fiber products and operation inconvenience of four-components embeddable and locatable spinning (ELS), a contact spinning based on simplified embeddable and locatable system was provided by simplifiying embeddable components and adding sponge contact device during twisting part. Yarn formation mechanisms were theoretically analyzed for the S-ELS, dry contact S-ELS, and wet contact S-ELS. By modification on ring spinning frame, the ramie yarns spun by different methods were compared. The results show that compared with the S-ELS and dry contact spinning for S-ELS, wet contact spinning of S-ELS can online soften the ramie fibers to facilitate fiber twisting and wrapping, producing the optimum qualified ramie yarns with the lowest hairiness and the highest strength.

Key words: ramie yarn, contact simplified embeddable and locatable spinning, yarn property, wet spinning
