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.
Claims22
A device for pretreating a carpet yarn comprising:
- a first ceramic plate and a second ceramic plate, a singe channel being formed between the first and second ceramic plates, the singe channel being open at a first end and a second end and allowing at least one yarn thread to pass through the singe channel;
- a first burner;
- and
- a second burner opposite the first burner, the first and second burners angled at least partially toward the first end of the singe channel.
A device for pretreating a carpet yarn comprising:
- a ceramic material, a part of the ceramic material defining a singe channel having a first end and a second end, the singe channel allowing at least one yarn thread to pass through the singe channel;
- a first burner;
- and
- a second burner opposite the first burner, the first and second burners angled at least partially toward the first end of the singe channel.
A device for treating a carpet yarn comprising:
- a heat-setting device for heat setting at least one staple-fiber carpet yarn thread;
- a singe burner having a singe channel open at a first end and a second end and allowing the at least one staple-fiber carpet yarn thread to pass through the singe channel;
- a first burner;
- and
- a second burner opposite the first burner, the first and second burners angled at least partially toward the first end of the singe channel.
