中文摘要：为探究喷气涡流纺纱线强伸性能提高的有效途径,基于Box-Behnken Design响应面设计方法,研究热处理温度、热处理速度和牵伸倍数对粘胶/低熔点涤纶喷气涡流纱断裂强力及断裂伸长率的影响规律,确定最佳热处理工艺,分析热黏合增强喷气涡流纱的机制。结果表明:喷气涡流纱断裂强力受热处理温度、热处理速度、牵伸倍数、热处理速度二次项、热处理速度和牵伸倍数交互项显著影响;断裂伸长率受热处理温度、热处理速度和二者的交互项显著影响,牵伸倍数影响不显著;响应面优化获得的最佳热处理工艺为热处理温度193℃,热处理速度90 m/min,牵伸倍数1.00。优化后纱线断裂强力较原纱提高10.7%,断裂伸长率提高2.8%;低熔点涤纶纤维受热产生挤压变形、点状和团块状热黏合是实现喷气涡流纱热黏合增强的关键。

外文摘要：In order to explore effective ways to improve the strength and elongation properties of air jet vortex spun yarn,the effect of the heat treatment temperature,heat treatment speed and draw ratio on the breaking strength and elongation of viscose/low melting point polyester air jet vortex spun yarn was studied based on the Box-Behnken Design response surface method.The optimal heat treatment process parameters were determined and the mechanism of thermal adhesion to reinforce the air jet vortex spun yarn was explored.The results show that the heat treatment temperature,heat treatment speed,draw ratio,the secondary term of heat treatment speed,heat treatment speed and draw ratio interaction terms have obvious influence on the yarn breaking strength.The elongation at break is significantly affected by the heat treatment temperature and heat treatment speed,while the influence of draw ratio is not obvious.The best parameter values of heat treatment process obtained through the optimization are heat treatment temperature 193℃,heat treatment speed 90 m/min,draw ratio 1.00.The yarn breaking strength is increased by 10.7%compared with the original yarn,and the elongation is increased by 2.8%after optimization.Furthermore,it is found that the heating deformation,point-like and agglomerated heat-bonding of low-melting polyester fibers are the key to achieve thermal bonding enhancement of air jet vortex spun yarn.
