Abstract
A method of making a dyed nylon walk-off mat having improved washfastness includes dyeing nylon yarn, or a tufted nylon mat, in a fiber reactive dye solution having a pH in the range of about 0.5 to about 2.5. The yarn is then heated, such as by steam, at a temperature above 200.degree. F., after which the yarn is treated with an alkaline solution followed by a heat treatment. A backing, such as of rubber or vinyl, is applied to the mat at an elevated temperature. The application of the backing at elevated temperature, and the heat treatment subsequent to application of the alkaline solution, may be performed simultaneously.
