The dyeing properties of polyester that has undergone cationic polymerization are superior to those of disperse-dyed normal polyester. Fabrics woven from cationically-dyed yarns are much more color-fast and this is especially important in the case of rich, dark colors.
Upon request, yarns may be manufactured to order containing a desired mixture of cationic and standard dispersed-dyed polyesters. Fabrics manufactured from such mixtures will have a blended appearance arising from their particular different dyeing characteristics. Cationic yarns may be made in both texturized and PDY versions. They are especially good for use in everyday topwear, sportswear, upholstery fabrics, home textiles and such as drapes. Because of their superior color-fastness, they are the preferred choice for swimwear.
