中文摘要：针对喷气涡流纺纱强力不高的问题,引入低熔点涤纶纤维利用热黏合机制增强喷气涡流纺纱线,借助T检验法比较不同热接触方式对纱线断裂功影响的显著性差异,通过正交试验研究热处理温度、热处理速度及牵伸倍数对纱线断裂功的影响规律,并进行最优工艺验证。结果表明:原纱采用非接触热处理方式断裂功提升更显著;纱线断裂功随热处理温度升高,先增加后下降,随速度增加,呈上升趋势;随牵伸倍数的增加,断裂功显著提高;最优热处理工艺为热处理温度145℃,热处理速度600 cm/min,牵伸倍数1.06。最优工艺热处理后喷气涡流纺纱线断裂功可提高13%。

外文摘要：Aiming at poor strength of air jet vortex spun yarn, low-melting point polyester fiber was introduced to reinforce air jet vortex spun yarn by heat bonding. The significant differences of the influence of different thermal contact modes on the yarn fracture work were compared by means of T-test. Orthogonal design was used to study the influence of heat treatment temperature, heat treatment speed and draw ratio on the yarn fracture work, and the optimal process was verified. The results show that the original yarn subjected to non-contact heat treatment has significantly improved fracture work. The fracture work of yarns increases first and then decreases with the rise of heat treatment temperature. When the speed increases, it shows an upward trend. With the increase of the draw ratio, the fracture work improves obviously. The optimal heat treatment process is: heat treatment temperature of 145 ℃, heat treatment speed of 600 cm/ min, and draw ratio of 1. 06, and the fracture work of the jet vortex spun yarn can be increased by 13% after the optimal process heat treatment.
