    • Dyed cellulosic regenerated elongate members such as fibres are produced by dyeing the regenerated members with a cationic direct dye after formation but before first drying. A method of producing the dyed elongate members comprises forming a dope containing cellulose or a cellulose compound in solution in a solvent, extruding the dope through at least one orifice into a bath containing water to form an elongate extrudate from which solvent is dissolved and/or the cellulose compound is converted to cellulose so as to form the elongate member, dyeing the formed but never dried elongate member with a cationic direct dye and optionally also with an anionic direct dye and then drying for the first time the dyed elongate member.
    • 染色的纤维素再生细长构件如纤维通过在形成之后但在第一次干燥之前用阳离子直接染料染色再生构件来制备。 一种生产染色的细长构件的方法包括在溶剂中在溶液​​中形成含有纤维素或纤维素化合物的涂料,通过至少一个孔将涂料挤出到含有水的浴中以形成细长的挤出物,溶剂从其中溶解和/或 将纤维素化合物转化成纤维素以形成细长构件,用阳离子直接染料和任选地还含有阴离子直接染料染色形成但未干燥的细长构件,然后首次干燥染色的细长构件。

    • An immersion method of dyeing textile material includes the steps of (a) providing a textile material comprising at least one of cotton and regenerated cellulosic fibers; (b) providing an aqueous dyebath in a weight ratio of dyebath:textile material of 10:1 to 20:1, the dyebath comprising a reactive dye and a carboxylate salt for salting out the dye onto the textile material, the carboxylate salt having a carboxylate anionic component and a monovalent cationic component, wherein the carboxylate salt is present in an amount effective for salting out the dye onto the textile material; (c) immersing the textile material in the aqueous dyebath under conditions sufficient to salt the dye onto the textile material; (d) adding to the dyebath an alkaline material to promote a reaction to form a chemical bond between the dye and the textile material; and (e) subjecting the dyebath containing the textile material and the alkaline material to conditions sufficient to form a chemical bond between the dye and the textile material.
    • 染色纺织材料的浸渍方法包括以下步骤:(a)提供包含棉和再生纤维素纤维中的至少一种的纺织材料; (b)提供染色浴的重量比为10:1至20:1的染料浴,染浴包含活性染料和羧酸盐,用于将染料盐析到纺织材料上,羧酸盐具有 羧酸盐阴离子组分和一价阳离子组分,其中羧酸盐以有效将盐析出到纺织材料上的量存在; (c)将织物材料浸入含水染浴中,条件足以将染料盐化到纺织材料上; (d)向染浴中加入碱性物质以促进反应以在染料和纺织材料之间形成化学键; 和(e)使含有织物材料和碱性材料的染浴经受足以在染料和纺织材料之间形成化学键的条件。
