【Abstract】 In fact, air jet textured yarn can be directly used in sewing thread if it has good tensile properties in the case of phisical index, but it is not true. we discussed and analysed the effect of twists on an improvement of the sewing thread structure and its surface characteristics by comparing the sewing thread mechanical properties in different twists, and a new concept “twist clamp effect” was given.更多还原
