Abstract
The device (80) described can be used in universal fashion for the intermingling, relaxing, and/or thermosetting of filament yarn (50) in a melt spinning process. It comprises a treatment chamber (80, 81), which is capable of being filled with a gas under essentially static overpressure and increased temperature, and features an intake aperture (83) and an outlet aperture (84), designed for preference as nozzles, for the passage of the yarn (50), through which the gas can flow, under pressure relief, respectively in or against the direction of the run of the yarn (50).
Claims17
A device for the intermingling, relaxing, and/or thermosetting of filament yarn (50) in a melt spinning process, comprising:
- a treatment chamber (80, 81), characterized in that the treatment chamber (80, 81), can be filled with a gas under an essentially static overpressure and increased temperature, and includes a feed aperture, an intake aperture (83) and an outlet aperture (84)for the passage of the yam (50), wherein the yarn is permeable under pressure relaxation by the gas, and
- the feed aperture includes a cross-sectional opening area for feeding the gas into the chamber, and the intake aperture and/or the outlet aperture includes a cross sectional opening area, wherein the feed aperture cross sectional opening area is substantially greater than the outlet aperture cross sectional opening area.
A device for the intermingling, relaxing, and/or thermosetting of filament yarn (50) in a melt spinning process, the device comprising a treatment chamber (80), adapted to be filled with a gas under an essentially static overpressure and increased temperature, the treatment chamber including a feed aperture, an intake aperture (83) and an outlet aperture (84)for the passage of the yam:
- (50), wherein the yam is permeable under pressure relaxation by the gas, and wherein the device is located to pass the yarn (50) directly from the outlet aperture (84) to a yam winding-up device (90), and
- the feed aperture includes a cross-sectional opening area for feeding the gas into the chamber, and the intake aperture and/or the outlet aperture includes a cross sectional opening area, wherein the feed aperture cross sectional opening area is substantially greater than the outlet aperture cross sectional opening area.
A device for intermingling, relaxing, and/or thermosetting of filament yarn (50) in a melt spinning process, comprising a treatment chamber (80, 81) filled with a gas under overpressure and increased temperature including:
- a feed aperture for feeding the gas into the treatment chamber,
- an intake aperture (83) permeable for the gas and for the passage of the yarn (50),
- an outlet aperture (84) permeable for the gas and for the passage of the yam (50),
- wherein the feed aperture, the intake aperture and the outlet aperture each include a cross sectional opening area, the feed aperture cross sectional opening area being substantially greater than the cross sectional areas of both the intake aperture and the outlet aperture, and wherein the overpressure of the gas fed through the feed aperture into the treatment chamber being essentially static and essentially does not start to relax until the gas flows out of the treatment chamber through the intake and/or outlet aperture.

- a feed aperture (83) permeable for the gas into the treatment chamber, and
- an intake aperture (83) permeable for the gas and for the passage of the yarn (50),
- an outlet aperture (84) permeable for the gas and for the passage of the yarn (50),
- wherein the feed aperture, the intake aperture and the outlet aperture each include a cross sectional area, the feed aperture cross sectional opening area being substantially greater than the cross sectional areas of both the intake aperture and the outlet aperture,
- wherein the overpressure of the gas fed through the fed aperture into the treatment chamber being essentially static and the overpressure of the gas essentially does not start to relax until the gas flows out of the chamber through the intake and/or outlet apertures, and
- wherein the device is located to pass the yarn (50) directly from the outlet aperture (84) to a yarn winding-up device (90).
