摘　　要：为提升夏季用纺织品或运动纺织品的舒适性,在分析液态水分管理测试仪(MMT)测试方法用针排传感器测试液态水扩散状态的基础上,选用4种典型纺织品,采用MMT法和自制的图像采集系统测试了纺织品的单向导水性能,比较了纺织品的单向导水效果。结果表明:对于采用点状施加拒水剂实现单向导水功能的纺织品及嵌织导电纤维的单向导水纺织品,MMT法容易出现较大的测试误差;采用图像法动态采集纺织品正反面的导水图像的新方法,获得了较为完整的水浸润信息,可以简捷地测试纺织品单向导水性能,并得到更加精准的测试结果。采用图像法动态采集纺织品正反面的导水图像的新方法具有良好的应用前景。The unidirectional water transport performance of textiles is a key index that affects the comfort of textiles or sports textiles used for the summer season.On the basis of analyzing the state of water diffusion measured by moisture management tester(MMT)needle array sensor,four types of fabrics are selected for actual measurement.It is reflected that the MMT method is prone to large test errors for fabrics with dot-array water repellent application for unidirectional water transport function and for unidirectional water transport fabrics with embedded conductive fibers.A new method was proposed to collect dynamically the water transfer image of the front and back sides of textiles,which offers more complete water infiltration information.The unidirectional water transfer performance of textiles in one direction were evaluated easily to obtain more accurate results.The new image method for dynamical collection of water transmission images of the front and back of textiles demonstrates a good application prospect.
