Provided are an inkjet printing method including at least a step of directly printing an inkjet ink containing an aqueous dispersion of a dye polymer having a repeating unit containing a structure derived from a dye on a fabric by an inkjet method; an inkjet ink containing the aqueous dispersion of a dye polymer; an ink cartridge filled with the inkjet ink; and a colored fabric.

A blended fabric having a patterned color includes a first portion comprised of cotton and a second portion comprised of polyester. A dye that has a strong affinity for cotton and a slight affinity for polyester is applied to the fabric. The dye gives the cotton portion a deep black color and applies a light gray color to the polyester portion. A combination of deep black cotton and light gray polyester combines to provide the patterned color of the blended fabric. The blended fabric may be comprised of a larger percentage of cotton than polyester that is spun into a single filament yarn that is then knitted into a Jersey Knit styled fabric, a looped knit terry fabric, or a fleece fabric. Further, the present invention comprises a blended fabric whereby dye absorption by the cotton and not by the polyester create darker and lighter patterns within the blended fabric.

A copolymer composition is disclosed with advantages for textile fibers, yarns, blended yarns, fabrics, and garments. The composition includes polyester copolymer, between about 4.5 and 5.5 percent adipic acid based on the amount of copolymer, between about 630 and 770 parts per million (ppm) of pentaerythritol based on the amount of copolymer, and between about 3.4 and 4.2 percent polyethylene glycol based on the amount of copolymer.
