    • A method is provided for dyeing a nonwoven fabric comprising a blend of fibers to a single color shade. The method includes selecting a nonwoven fabric formed of a blend of polyester and nylon fibers, where the polyester fibers comprise about X percent by weight of the fabric and the nylon fibers comprise about Y percent by weight of the fabric. A single bath is formulated having about X percent by weight disperse dye and about Y percent by weight acid dye, adjusted for the desired color shade/depth. The nonwoven fabric is then dyed to obtain a dyed fabric having a single color shade of at least Grade 4 when measured in accordance with AATCC Test Method 153 and a colorfastness of at least Grade 4 when measured in accordance with AATCC Test Method 61.
