A method for the treatment of textiles, which contain highly crosslinked acrylic polymers before dyeing; a process for dyeing textiles; before dyeing treated textile product; as well as the textile product

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.
