摘　　要：分析了聚丙烯纺粘热轧非织造布的热轧黏合机理,其结构可以用薄膜区—纤维区两相结构来描述。研究了热轧工艺对纺粘热轧非织造布力学性能的影响。在面密度一定的条件下,提高轧棍温度有利于增加薄型纺粘法非织造布的强力;在其他条件不变的情况下,提高轧棍压力有助于改善非织造布的力学性能,而提高轧棍线速度则会使非织造布强力下降;在生产高面密度非织造布时,为保持轧棍一定的线速度,可调整轧棍的温度和压力参数作为补偿,以保证非织造布强力稳定。The thermal bonding mechanism of PP spunbonded nonwovens was analyzed and their structure could be demonstrated by two phases of film area and fiber area. The influence of thermal bonding technique on mechanical property of spunbonded nonwovens was studied in the paper. Under the condition of the certain area density, enhancement of calendar pressure could help to improve the mechanical property of the nonwovens, and enhancement of linen speed could make strength of the nonwovens decrease. While manufacture nonwovens of high area density, in order to maintain the certain linen speed the temperature and pressure parameter could be adjusted as compensation to guarantee the stabilization of nonwovens strength.
