    Abstract: FIBROUS MATERIALS MADE OF POLYMERS CONTAINING AT LEAST 85% OF POLYACRYLATONITRILE CAN BE OPTICALLY BRIGHTENED IN A SAID MATERIAL WITH A LIQUOR CONTAINING A 1-(4''-B-ALKOXYETHYL SULFONYL)-PHENYL-3-B-CHLOROPHENYL-$2-PYRAZOLINE, ADJUSTING THE IMPREGNATED MATERIAL TO A LIQUOR CONTENT OF ABOUT 5 TO 120% BY WEIGHT REFERRED TO THE DRY-WEIGHT OF THE GOODS, AND HEATING IT FOR ABOUT 2 SECONDS TO 30 MINUTES TO A TEMPERATURE OF ABOUT 100 TO 150*C.

    Abstract translation: 1288545荧光增白FARBWERKE HOECHST AG 19 Jan 1970 [30 Jan 1969] 4340/70标题DIP包含至少85％的聚丙烯腈的聚合物的纤维材料通过用含有通式光亮剂的液体浸渍材料进行光学增白，其中A代表 支链或非支链C 2-4亚烷基，R SP 1表示C 1-4烷基，R SP 2表示C 1-4烷基或两个基团 R 2 与氮原子一起形成饱和杂环，X表示无色阴离子，n为1或2，将材料的液体含量调整为参考材料的5-120重量％ 并在100 <-150℃下加热，优选用蒸汽加热2秒至30分钟。 如果亮面织物要立即印刷，则优选在50 <-150℃进行中间干燥。 添加增稠剂例如淀粉醚，黄蓍胶，角豆粉和结晶胶，以防止在干燥过程中荧光增白剂的迁移。 当增亮液中加入脂肪酸和氧乙基化氨的非离子缩合产物和/或脂肪酸和低分子量脂肪族多胺的季
    缩合产物时，可实现增强的增亮。 其中A，R 1，R 2，X和n具有上述含义的通式的第二增白剂显示绿蓝色荧光，并且当应用时 与式II化合物的混合物，以补偿后者的淡红色。

    Abstract: Compounds of the formula

    WHEREIN R1-R4 are fluorine, chlorine or perhaloalkyl groups; X1X4 are hydrogen, halogen, or alkyl halide; Y is thiourea, pyridine, quinoline, or the alkyl or hydroxyalkyl derivatives thereof; A is an accompanying anionic moiety; r is an integer from 1-2, m and n are integers from 0-20, and s is an integer from 1 up to the total negative charge of A. These compounds are useful as surface active agents and for imparting water and oil repellent properties to various substrates such as textiles, leather and paper.

    Abstract: Aqueous emulsions are provided, which are used for the preparation of baths serving to produce wash-fast water-repellent finishes on fiber materials. These emulsions contain relative to the dry weight of the components (a) 9 to 54 percent of a methylolaminotriazone etherified with higher fatty alcohols, (b) 4.5 to 48 percent of a waxy substance and (c) 40 to 55 percent of a reaction product of an aminoplast precondensate, a monohydroxy compound, a polyethylene glycol and an oxygen-containing aliphatic or heterocyclic amine. The solids content of these emulsions is 10 to 50 percent by weight. For use these emulsions are diluted with water, and a curing catalyst is added.
