摘　　要：将本实验室自制的芳香型复鞣剂FRA应用于山羊蓝湿革的复鞣工艺中,通过对烘焙剖层后的革坯挥发出的香味物质,采用感观等级和气相色谱-质谱联用仪分析评价,并与直接添加柠檬香精的留香效果进行对比。结果表明:FRA处理革坯的留香效果,要明显好于直接用香精进行加香处理。通过物理力学性能测试以及采用评分方法对革坯进行感观效果评价,并与利华坦L进行了复鞣效果对比。结果表明:FRA能使革坯小幅增厚,且可提高革坯的丰满度和紧实性,但效果不如利华坦L明显;FRA还能小幅提高革坯的抗张强度和撕裂强度,但对伸长率的贡献不明显。研究表明,FRA是一种兼具加香和复鞣效果的新型皮革复鞣材料。The fragrance retanning agent（ FRA）, previously prepared in our laboratory, was used in retanning wet blue goatskin. To contrastively evaluate odor reservation of FRA and lemon perfume on retanned leather, the flavor compounds volatilized from treated leather were analyzed by sensory test and GC - MS. The results show that the odor reservation of leather treated with FRA is significantly better than that treated by lemon perfume directly. To comparatively observe the effects of FRA and Levotan L （ a commercial polyurethane resin） on retanned leather, the physical properties of leather were measured and the sensory test was taken. The leather retanned with FRA shows improvement in fullness and tightness, but the effects are not as good as Levotan L. Also, the results show small improvement in tensile strength and tear strength, but fall in elongation. In a word, FRA as a new functional material can both satisfy the requirements of perfumed finishing and retanning for fragrance leather.
