Abstract
A process for improving the colorfastness of dyed thermoplastic textile materials is described. The process involves heatsetting the materials to a temperature which minimizes the amount of semi-crystalline regions, dyeing the material and subjecting it to a reductive clear. The process can be used on a variety of textile materials including fibers, yarns and fabrics. The process is particularly effective in achieving high colorfastness on microdenier products, even when the product is dyed a dark shade. The materials also retain good strength and flexibility characteristics.
