摘　　要：为了能够保持运动中大汗淋漓时的舒适状态,研究液态水在织物中传输与快干性能是必要的。文章提出了织物中液态水传输与快干评价的指标,即滴水扩散时间、最大面积传输耗时、最大传输面积、经纬向最大传输跨距、蒸发速度等。液态水在织物中的传输行为通过观察其传输域变化来反映,呈现出与织物组织、纱线排列密度、纱线线密度、织物厚度、织物平方米质量等结构因素相关的初始阶段、增速阶段、稳定阶段和减缓阶段四个时期。通过对10种不同规格织物进行滴水扩散测试和水分蒸发速率测试,织物中液态水传输与织物厚度密切相关,织物厚度为液态水的渗漏提供空间但弱化了液态水的铺展和快干;纱线线密度影响织物表面孔隙,成为影响液态水铺展蒸发的主要因素;经纬密度通过与纱线线密度的匹配形成对液态水传输的影响。研究结果对于高品质运动服装面料的研发具有重要的指导意义。The liquid water transport and rapid drying behavior in fabrics,usually referred to as moisture absorption and rapid drying,means that when the human body generates a lot of sweat during intense exercise,sweat can be quickly absorbed and transmitted to the outer surface of fabrics to quickly volatilize,so that the body can maintain a dry and comfortable function.The behavior directly affects the human wearing comfort and health status.According to the current development trend of functional fabrics,moisture absorption and rapid drying has become a basic requirement for underwear,sports,medical and clothing in other fields,and has bright prospects for development.Combined with the exploration of related fields by researchers,it can be seen that the liquid water transport and rapid drying in fabrics has become a research hotspot,which makes the law of moisture absorption and rapid drying properties increasingly clear,and the characterization methods are increasingly accurate and diversified.However,as the liquid water transport and rapid drying in fabrics is affected by many factors,it is necessary to strengthen the guidance of the research results for the actual product development.To keep the human body in a comfortable state when people sweat during exercise,the study took polyester woven fabrics as the research object to characterize the liquid water transport and rapid drying behavior in fabrics.Firstly,the drip diffusion test and water evaporation rate test of 10 kinds of fabrics with different specifications were carried out with the help of image processing technology,and the data of water transport process were accurately obtained.Then,the indexes of liquid water transport and rapid drying in fabrics were put forward,such as the drip diffusion time,maximum transmission time,maximum transmission area,maximum transmission span in the warp and weft direction,and evaporation rate,and the moisture absorption and rapid drying performance of fabrics was analyzed.Finally,the factors influencing the moisture absorp
