ABSTRACT:
Methods of and apparatus for cold dyeing pile fabrics, particularly carpets, wherein dye liquor is first applied to the pile side of the fabric in an amount between 150% and 300% of the material weight, the dye impregnated fabric then being coiled, under tension, into a roll and the roll allowed to stand, all at room temperature. The magnitude of the tensile force applied to the fabric is greater than about 90% of that required to cause dye liquor to emerge from the roll, but is not more than that which enables 5%, at the most, of the liquor to emerge from the roll.
