摘要
介绍了几种汽车座椅皮革材料的生产方法及性能特点。比较分析了汽车行业对人造革柔軔性的几种客观测试方法,并采用主观评价(评价员感知)及客观测试(压入刚度、45°斜坡、环形柔韧性)的方法对主流车型所用到的14款人造革进行了柔軔性对比测评研究。结果发现:针对细纹理材料,压入刚度、环形柔韧性测试结果与评价员主观评价结果有较好的正相关性,通过压入刚度、环形柔軔性分别模拟感知评价过程中材料表面的轻触柔初感及抓捏柔初感,并通过一定技术指标的设定可开发出高柔初性的人造革材料。
The production methods and performance characteristics of artificial leathers of automotive seat were introduced.Several objective testing methods of artificial leather flexibility in automobile industry were compared and analyzed.The flexibility of 14 kinds of artificial leathers used in mainstream models was evaluated by both subjective(indentation stiffness and ring flexibility and 45°slope method)and objective(touch sensation)methods.The results show a positive correlation between subjective(indentation stiffness and ring flexibility)and objective(touch sensation)for leathers with fine grain.Moreover,tactile flexibility and grip/pinch flexibility of the materials can be simulated by indentation stiffness and ring flexibility,respectively.With certain technical specifications,artificial leathers with high flexibility can be developed.
