摘要：

为获得更高强力的喷气涡流纺纱线,通过引入涤纶长丝制备喷气涡流纺粘胶/涤纶包芯纱。采用统计分析等方法研究了芯丝线密度、纺纱速度对喷气涡流纺粘胶/涤纶包芯纱强伸性、条干不匀和毛羽的影响规律,同时对比分析了不同纺纱条件下包芯纱的结构外观。研究结果表明:芯丝线密度、纺纱速度对喷气涡流纺粘胶/涤纶包芯纱各性能响应值有不同程度的影响;纺纱速度过高或过低均不利于包芯纱成纱的强伸性提高和条干均匀性改善,纺纱速度的增加会使毛羽H值增大;在一定范围内,增加芯丝线密度有利于包芯纱强伸性的提高,随芯丝线密度的增加,包芯纱毛羽H值减小;此外,选用较大的芯丝线密度和较高的纺纱速度时,纺制的包芯纱芯丝外露现象越明显。

Abstract:

In order to obtain higher strength air-jet vortex spun yarns, the viscose/polyester core-spun yarn was produced on air-jet vortex spinner by adding a polyester filament in the yarn formation process. The effects of core filament linear density and the yarn delivery speed on the strength, elongation, unevenness and hairiness of air-jet vortex spun viscose/polyester core-spun yarn were studied by statistical analysis method. The structure and appearance of core-spun yarns under different spinning conditions was compared and analyzed. The results show that the core filament linear density and yarn delivery speed have different effects on the performance of air-jet vortex viscose/polyester core-spun yarn. In general, either too high or too low yarn delivery speed is not conducive to improving yarn strength-elongation performance and improving yarn evenness for core-spun yarns obtained, and the increase of yarn delivery speed will increase the hairiness H value. In a certain range, increasing the core filament linear density is beneficial to improve the strength and elongation of the core-spun yarn, and the hairiness H value of the core-spun yarn decreases with the increase of the core-filament linear density. In addition, when the larger core-filament linear density and higher yarn delivery speed are selected in air-jet vortex spinning, there is more obvious exposure for the core filament in viscose/polyester core-spun yarn.
