摘　　要：为研究织物纬向物理力学性能与喷气织机车速的关系,测试了不同车速织机生产织物两侧的捻度差异。采用分段拆纱取样法分别对不同车速下所织织物纬纱两侧捻度及强伸性、织物强伸性、抗弯长度及染色性能进行测试与分析。结果表明:车速越低,纬纱退捻产生问题越多,织物两侧色差越大;车速越高,纬纱飞越梭口时处于无握持状态时间越短,纬纱退捻量减少,织物两侧纬纱捻度、强力损失减小,废边侧织物断裂强力及抗弯刚度损失减小,织物两侧染色效果变化较小,但车速增加对原纱要求提高,因此,选择合适车速,是喷气引纬提高产质量的关键。In order to study the relationship between the physical mechanical properties of fabrics and air-jet loom speed,the twist difference on both sides of the fabrics at different weaving loom speeds（500 r/min,600 r/min and 700 r/min） is analyzed in this paper.Samples of the fabrics are selected by ravel weft yarns on the different parts,and the twist distribution,the weft strength and elongation,the fabric strength and elongation,the fabric bending length,and the fabric dyeing properties of each weft yarn section were tested separately at different speeds.The experiment result shows that the weft yarn untwisting causes more problems and difference between both sides of the color is greater when the speed is lower.On the contrary,the increasing of the weft speed will decrease the weft yarn freely flying time,the untwist degree of the weft yarn was decreased with the shortening of weft yarn insertion time,and the weft strength loss,the fabric breaking strength loss,the bending rigidity loss,the dyeing difference on both side of the fabrics was decreased as well,but raw yarn quality requirements were improved with the speed simultaneously.Therefore,proper appropriate speed is the key to improve the quality and output of production by air-jet weft insertion.
