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.

A method for treating a carpet yarn having a carpet yarn surface and having fine, tiny hairs on the carpet yarn surface, the carpet yarn being made of a carpet yarn material having a melting point, the carpet yarn being a staple-fiber carpet yarn, the method comprising the steps of:
- exposing the carpet yarn surface for a brief duration to a temperature that is very high relative to the melting point;
- and
- forming a carpet from the carpet yarn.
