摘要： In fiber products (e.g. yarns, woven fabrics, knit fabrics) comprising highly crosslinked polyacrylic fibers (made of acrylic fibers by partially hydrolyzing a nitrile group to generate an amido group and a carboxylic acid group), fibers blended with the highly crosslinked polyacrylic fibers can be dyed in an even hue. A pre-dyeing treatment process for such fiber products (e.g. yarns, woven fabrics, knit fabrics) comprising highly crosslinked polyacrylic fibers comprises a pretreatment step of immersing the fiber product into an acidic solution and treating it at a high temperature and an elevated pressure. A dyeing process comprises the steps of conducting this pre-dyeing treatment process, and thereafter conventionally dyeing fibers which are blended with the highly crosslinked polyacrylic fibers. A pretreated fiber product and a fiber product are obtained by the pre-dyeing treatment process and the dyeing process mentioned above.

摘要： A textile product, such as a yarn, woven fabric, or knit, which contains fibers of a highly crosslinked acrylic polymer (fibers obtained from acrylic fibers by partly hydrolyzing the nitrile groups to form amide groups and carboxy groups) is dyed without causing a difference in hue between the highly crosslinked acrylic polymer fibers and the fibers used in combination therewith. The method of treatment before dyeing comprises a pretreatment step in which the textile product, such as a yarn, woven fabric, or knit, which contains fibers of a highly crosslinked acrylic polymer is immersed in an acid liquid and treated at a high temperature under pressure. Also provided are: a method of dyeing which comprises, after the pretreatment, dyeing the textile product by a technique which is commonly used for dyeing the fibers used in combination with the highly crosslinked acrylic polymer fibers; a textile product obtained by the method of pretreatment before dyeing; and a textile product obtained by the method of dyeing.
