汽车内饰用阻燃针刺非织造布的性能影响因素

本文以开发汽车内饰用阻燃针刺非织造布为目的，选用阻燃涤纶纤维和热塑性PP/PE复合纤维（ES纤维）为原料，经针刺工艺和轧光工艺制成了阻燃针刺非织造布。分别对阻燃针刺非织造布进行了硬挺度、透气性、力学性能、燃烧性能和极限氧指数的测试，并详细分析了影响这些性能的原因。结果表明，随着针刺非织造布面密度的增大，针刺非织造布的硬挺度增大，力学性能提高，阻燃性能提高，而透气性下降；轧光整理使得针刺非织造布的硬挺度增大，透气性下降，力学性能提高，阻燃性有所提高。

Factors influencing properties of flame retardant needle-punched nonwoven for automobile interiors

In order to develop fire retarded interior needle-punched nonwoven used for automobile, fire retarded polyester fibers and thermal plastic PP/PE fibers were selected to manufacture the fire retarded needle-punched nonwoven by the needle-punched process and calendar process. The stiffness, permeability, mechanical properties, flammability and limited oxygen index of the neddle-punched nonwoven were all tested respectively, and the factors that affect those properties were analysized. The results show that with the surface density of the needle-punched nonwoven increasing, the stiffness, mechanical properties and fire retardance all increase correspondingly. And the calendar finishing make the stiffness, mechanical property and flame retardance of the needle-punched nonwoven improving, while the permeability decreases.
