摘要：研究了聚烯烃织物背胶在不同干燥温度和风速时的干燥曲线、干燥速率曲线、水分有效扩散系数（Deff）以及干燥活化能（Ea）,建立了干燥的数学模型。研究结果表明：聚烯烃织物背胶的整个干燥过程属于降速干燥,干燥温度和风速的升高都有利于缩短干燥时间;Page模型能较好描述聚烯烃织物背胶的干燥过程,并且Deff为（2.46~4.15）×10^-8m^2/s,Ea为26.95 kJ/mol。
The drying curves,drying rate curves,moisture effective diffusivity（Deff）and drying activation energy（Ea）of polyolefin fabric adhesive were investigated at different drying temperatures and air velocities. The drying mathematics model of the polyolefin fabric adhesive was established. The research results showed that the entire drying process of polyolefin fabric adhesive was falling rate drying. The drying time was shortened with increasing drying temperatures and air velocities. The Page model could preferably describe the drying process of the polyolefin fabric adhesive,and the Deffand Eawere（2.46-4.15）×10^-8m^2/s and 26.95 kJ/mol respectively.
