More Information
Summary:PROBLEM TO BE SOLVED: To provide a process for the modification of an artificial cellulosic fiber capable of imparting the fiber with abrasion resistance without deteriorating the dyeability of the fiber, causing little lowering of the strength and giving a modified fiber having high water-retaining and absorbing properties and soft feeling. SOLUTION: The objective process for the modification of an artificial cellulosic fiber comprises the application of a glyoxal resin, an acidic catalyst or a latent acidic catalyst and polyethylene glycol to an artificial cellulosic fiber followed by the heat-treatment and the crumpling of a produced fiber cloth with liquid flow. The weight concentration ratio of the polyethylene glycol to the glyoxal resin is 1.5-6.0.
