摘要： 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.
摘要翻译： 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。

摘要： Fibrous materials of synthetic polyamides or cellulose esters are capable of optical brightening according to the so-called thermosol process (padding at ambient temperature with subsequent fixation by a heat treatment) when fixing in the presence of an auxiliary consisting of a polyalkylene glycol and a fatty alcohol oxethylate. Optionally foam-depressing phosphoric acid alkyl esters and branched carboxylic acid esters are used additionally.

摘要： Plastic articles, especially plastic optical lenses are tinted by immersing the plastic article in an aqueous dispersion of tinting agent and exposing the dispersion and immersed article to microwave radiation to bring the dispersion to ebullition; the ebullition is maintained for at least 2 seconds with transfer of tinting agent from the dispersion to the article to tint the article; the tinted article is removed from the dispersion and rinsed with water. The method achieves tinting in significantly shorter times than conventional methods and employs water-based dispersions thereby avoiding emission of vapors of organic solvents.

摘要翻译：将塑料制品特别是塑料光学透镜通过将塑料制品浸入着色剂的水性分散体中而着色，并将分散体和浸没物品暴露于微波辐射以使分散体沸腾; 将调色剂保持至少2秒，同时将着色剂从分散体转移到制品上以着色该制品; 将有色制品从分散体中取出并用水冲洗。该方法比常规方法实现了明显缩短的时间，并且使用水基分散体，从而避免了有机溶剂蒸气的排放。

摘要： Polyamide fibre material treated with fluorescent whiteners (also known as optical brighteners) is prevented from being stained by applying to the fibre material either simultaneously with the fluorescent whitener or in the form of an aftertreatment of the whitened fibre material, an emulsion containing a watersoluble fixing agent with affinity to fibres, an organic solvent or solvent mixture and at most 10 % of water, relative to the preparation, and optionally an organo-soluble dispersing agent. The process is carried out at 20* to 120*C according to the exhaustion method. The finish renders the fibrous material resistant to staining and soiling.
