    Abstract: Hazy or frosty appearance of mixtures of polyester and cellulosic fibers when dyed with disperse dyes is suppressed by adding to the aqueous dye bath a small amount of low copolymer of acrylamide or the like with a water-soluble maleic or fumaric acid ester, and with or without an additional water-soluble vinyl compound, all as defined infra. The copolymer is normally a liquid miscible with water in all proportions at 10.degree. C. or below. Disperse dye is fixed to the polyester fibers by heating as in the Thermosol process. Dyes for the cellulosic fibers can also be included in the dye bath so that the cellulosic fibers are also dyed in the same treatment. Alternatively the cellulosic fibers can be separately dyed, preferably after the polyester fibers are dyed.

    Abstract translation: 通过向水性染料浴中加入少量的丙烯酰胺等低水分共聚物与水溶性马来酸或富马酸酯,以及与或不同的方法,通过将分散染料染色的聚酯和纤维素纤维的混合物的混合物的朦胧或冷冻外观抑制, 没有额外的水溶性乙烯基化合物,全部如下文所定义。 共聚物通常是在10℃以下以各种比例与水混溶的液体。 分散染料通过像Thermosol工艺那样加热固定在聚酯纤维上。 用于纤维素纤维的染料也可以包含在染浴中,使得纤维素纤维也在相同的处理中染色。 或者,纤维素纤维可以分开染色,优选在聚酯纤维染色之后。
