Abstract
A method and apparatus for bonding, coating and/or dyeing yarn which impregnates the yarn with a solution containing at least one of a polymer resin, coating or dyestuff dissolved in a flammable solvent/carrier. The solvent/carrier in the impregnated yarn is then ignited to burn away a part of the solvent/carrier from the yarn. A portion of the solvent/carrier remains in the yarn to prevent damage to the yarn. The yarn containing the residual solvent/carrier then is dried at an elevated temperature.
