荧光增白剂S-ER是用于聚酯纤维和织物的新型增白剂,具有白度高,牢度好,定型时不泛黄,且对阳离子柔软剂稳定,可与次氯酸纳、双氧水及还原性漂白剂同浴使用等特点,在国内外市场上很畅销。上海助剂厂在沈阳化工研究院技术转让的基础上,经过双方共同改进后,上海市科委把其列为1996年上海市科技成果推广计划项目。经上海助剂厂工程技术人员一年的努力、由产业化得到的产品经上海华辉印染有限公司和上海市印染技术研究所等单位使用和检测,并与国内市场上现有涤沦荧光增白剂对比,荧光增白剂S-ER的白度是荧光增白剂DT的10倍,且比国内市场上同类结构产品要好,采用高温高压法与热9熔法对涤纶织物染色所得结果基本一致,尤其适用于
Fluorescent whitening agent S-ER is a new brightener for polyester fibers and fabrics. It has high whiteness, good fastness, and does not yellow when setting. It is stable to cationic softeners and can be used with sodium hypochlorite. Hydrogen peroxide and reducing bleaches are used in baths and other products, and they are very popular in the domestic and foreign markets. Shanghai Auxiliary Plant was based on the transfer of technology from the Shenyang Chemical Research Institute. After mutual improvement, the Shanghai Science and Technology Commission listed it as a Shanghai Science and Technology Achievement Promotion Project in 1996. After one year’s efforts by the Shanghai Auxiliary Plant engineering and technical personnel, the products obtained from industrialization were used and tested by Shanghai Huahui Printing and Dyeing Co., Ltd. and the Shanghai Institute of Printing and Dyeing Technology, etc., and the existing polyester-fluorene fluorescence increase in the domestic market. Compared with white agent, the whiteness of fluorescent whitening agent S-ER is 10 times that of fluorescent whitening agent DT, and it is better than similar structure products on the domestic market. The result of dyeing polyester fabric with high temperature and high pressure method and hot 9 melting method is basically the same. Consistent, especially suitable for
