  A method for treating textile fibres and synthetic polyamide fibres to enhance their affinity for disperse dyestuffs which comprises treating the fibres with an aqueous solution or dispersion of an arylating agent. The arylating agent contains both a benzene or naphtalene ring and a reactive group, such as a halo-triazine group. The fibres may be treated by exhaustion from long liquors or by padding, and the affinity for disperse dyestuffs is considerably increased thereby.

  一种处理纺织纤维和合成聚酰胺纤维以提高其对分散染料亲和力的方法，包括用芳基化剂的水溶液或分散液处理纤维。 芳基化剂含有苯环或萘环和活性基团，如卤代三嗪基团。 纤维可通过长液排气或轧染处理，从而大大提高对分散染料的亲和力。

  @ There is disclosed a process for blending rubber latices with carbon black or other reinforcing pigments which comprises the use of a 60/40 to 40/60 butadiene/methacrylic acid latex which has been converted to a water soluble polymer through treatment with an alkali metal hydroxide. Said converted butadiene/methacrylic acid latex is then combined with dry carbon black at a level of 1 to 2 percent butadiene/methacrylic acid dispersing latex solids based on weight of the carbon black. The blended carbon black butadiene/methacrylic acid dispersion is added to rubber latices prior to coagulation. More specifically, this invention is concerned with a carbon black dispersion and its addition to a rubber latex.

  本发明公开了一种将橡胶胶乳与炭黑或其他增强颜料混合的工艺，该工艺包括使用 60/40 至 40/60 丁二烯/甲基丙烯酸胶乳，该胶乳已通过碱金属氢氧化物处理转化为水溶性聚合物。然后将转化后的丁二烯/甲基丙烯酸胶乳与干碳黑混合，丁二烯/甲基丙烯酸分散胶乳固体含量为碳黑重量的 1%至 2%。混合后的炭黑丁二烯/甲基丙烯酸分散体在凝固前加入橡胶胶乳中。更具体地说，本发明涉及一种炭黑分散体及其在橡胶胶乳中的添加。
