摘　　要：介绍轮胎用锦纶66帘布压延过程及其工艺控制、压延帘布常见质量问题及其解决措施。严格控制热炼胶塑性值和供胶温度、保证原帘布干燥、导开帘布松紧一致、帘布对中、供胶和递布稳定、帘布压延张力和压延速度合理和均衡、压延机辊温和帘布冷却辊温稳定、压延机积胶量适当、压延帘布卷取协调性好,以及严格工艺操作,可以有效解决压延帘布幅宽和厚度不合格、扒皮、露白、罗股、劈缝、跳线、出兜、压坏和褶子等质量问题。The calendaring process of nylon 66 tire cords and the process control method were introduced. The common quality issues were analyzed and the corrective action was provided. The common quality defects included non-uniform sheet width and thickness, holes in the sheet, exposed cord, distorted cord, calender cuts, missed cord, burst, crushed part and wrinkles. To effectively minimize the quality defects, the corrective actions were recommended as follows： precisely control the plasticity value and temperature of rubber, completely dry the original fabric, minimize speed changes, control the fabric centering, stable feeding of rubber and fabric, properly control the separating forces, adjust the calendering temperature, keep the proper amount of rubber bank between rolls, maintain a stable winding process, and operate strictly according to the standard operating procedures.
