摘　　要：使用一浴浸胶机生产尼龙66浸胶帘子布,从工艺和设备两方面分析生产过程中帘子布表面产生胶斑的原因,探讨挤压辊空气弹簧压强、无挤压辊的浸胶区结构、刮布线数量、单/双面吸嘴等因素对浸胶帘子布千米胶斑面积的影响。结果表明:在尼龙66浸胶帘子布生产中,减小挤压辊空气弹簧压强或使用无挤压辊的浸胶区结构、增加刮布线数量、使用双面吸嘴替代单面吸嘴,均有利于减小浸胶帘子布的千米胶斑面积;综合使用无挤压辊的浸胶区结构、刮布线6根和双面吸嘴,生产的尼龙66浸胶帘子布表面胶斑显著减少,千米胶斑面积仅为0.9 cm^2。A nylon 66 dipped cord fabric was produced using one bath dipping machine.The reasons for the gum spots on the surface of cord fabric were analyzed from two aspects of process and equipment during the production process.And the influence of the air spring pressure of extrusion roller,dipping zone structure without extrusion roller,number of scraping wires,single-or double-sided suction nozzle on the gum spots area per kilometer of dipped cord fabric was discussed.The results showed that the gum spots area of dipped cord fabric per kilometer could be decreased by reducing the air spring pressure of extrusion roller or using the dipping zone structure without extrusion roller,increasing the number of scraping wires,and using double-sided suction nozzle instead of single-sided suction nozzle in the production of nylon 66 dipped cord fabric;and the gum spots area of the prepared nylon 66 dipped cord fabric was significantly decreased to 0.9 cm^2 per kilometer and the number of gum spots on the surface were significantly reduced by comprehensively using the dipping zone structure without extrusion roller,6 scraping wires and double-sided suction nozzles.
