Abstract
A method and machine for treating yarn may include feeding the yarn through both a heat treatment and an air jet texturing nozzle. The texturing nozzle may be supplied with compressed air, producing an air jet with a speed greater than Mach 1 in the yarn channel. The heat treatment may be performed before and/or after feeding the yarn through the texturing nozzle.
