ABSTRACT:
A method for pretreating a staple-fiber carpet yarn (5) before it is processed to make a carpet, in order to reduce the hairiness and fuzz accumulation associated with such yarns. The surface of the carpet yarn (5) is exposed for a brief time to the action of a temperature which is very high relative to the characteristic temperatures of the carpet yarn material. This can be carried out in a singe burner (100) through which the carpet-yarn threads (5) are guided in their lengthwise direction.
