摘要

以铬鞣牛皮为原料,在整理过程中将其染成白色。在整理后的整理层上分别添加1%、2%、3%、4%和5%的l -抗坏血酸。对照组不添加l -抗坏血酸,按标准方法加工。在这些过程之后,在柯尼卡美能达CM 3600d分光光度计上进行颜色测量分析。为了考察l -抗坏血酸对皮革其他性能的影响,按照TS 1008 EN ISO 105-B02 (2001 TS EN ISO 11640 2001)进行了耐光牢度试验,并按照标准方法进行了干摩擦牢度试验。根据NCSS (Number Cruncher Statistical System)方法对研究结果进行统计评价。研究结果显示,l -抗坏血酸使皮革呈珍珠粉色。结果表明,经l -抗坏血酸处理后,皮革的干摩擦牢度有所提高。在耐光性测试中,实验组皮革用蓝标记录的结果较好。

Application of L-Ascorbic Acid as an Antioxidative Colorment in Leather Finishing
In this study, chrome tanned bovine crust leathers were dyed white during finishing process. Experiments with 1%, 2%, 3%, 4% and 5% L-ascorbic acid addition were performed on the finishing layer of the finishing application. L-ascorbic acid was not added to the control group and processed according to the standard method. After these processes, color measurement analyzes were performed on Konica Minolta CM 3600d spectrophotometer. In order to investigate the effects of L-ascorbic acid on other performance properties of leather, light fastness test according to TS 1008 EN ISO 105-B02 (2001 TS EN ISO 11640 2001) and dry rub fastness test according to standard method were performed. The results of the study were statistically evaluated according to the NCSS (Number Cruncher Statistical System) method. As a result of the research, it was observed that L-ascorbic acid gave a pearly pink color to the leathers. It was found that the dry rubbing fastness of the leathers treated with L-ascorbic acid improved. In the light fastness tests, the results of the experimental group leathers were recorded better by the blue scale.
