Abstract
A method and an apparatus are disclosed for texturing a yarn product. The method includes the step of passing the yarn product along a yarn path through a liquid jet arrangement. The method also includes the step of applying a force to the yarn transversely to the axis thereof.
Claims19
A method of texturing a yarn product comprising the steps of:
- passing the yarn product along a yarn path through a liquid jet arrangement which applies a force to the yarn transversely to the axis thereof, texturing the yarn product and cooling the yarn product, wherein the yarn product is cooled by the liquid jet arrangement;
- and
- immersing the yarn product in a liquid immersion cooling zone.
The method of 1 further comprising the step of controlling the texturing of the yarn with a feedback arrangement.
An apparatus for texturing a yarn product comprising:
- a liquid jet arrangement adapted to apply to the yarn product traveling along a yarn path through the jet arrangement a force transversely to the axis of the yarn product, wherein the jet arrangement is in a filament spinning apparatus and disposed downstream of a cooling arrangement in which the yarn product passes through a fluid to be cooled by heat transfer thereto, wherein the cooling arrangement includes a cooling chamber with a fluid inlet and a fluid outlet for cooling fluid to be passed therethrough, and the cooling arrangement includes a yarn product inlet and yarn product outlet, and wherein the cooling fluid is passed in contraflow relative to the yarn product.
An apparatus for texturing a yarn product comprising:
- a liquid jet arrangement adapted to apply to the yarn product traveling along a yarn path through the jet arrangement a force transversely to the axis of the yarn product, wherein the jet arrangement is in a filament spinning apparatus and disposed downstream of a cooling arrangement in which the yarn product passes through a fluid to be cooled by heat transfer thereto, wherein the cooling arrangement includes a cooling chamber with a fluid inlet and a fluid outlet for cooling fluid to be passed therethrough, and the cooling arrangement includes a yarn product inlet and yarn product outlet, and wherein the chamber includes seals against escape of cooling fluid at the yarn product inlet and the yarn product outlet.
An apparatus for texturing a yarn product comprising:
- a liquid jet arrangement arranged in a filament spinning apparatus and adapted to apply to the yarn product traveling along a yarn path through the jet arrangement a force transversely to the axis of the yarn product, wherein the jet arrangement is disposed downstream of a cooling arrangement, wherein the cooling arrangement includes a cooling chamber for cooling fluid to be passed therethrough, wherein the cooling fluid is a liquid, and wherein the liquid turbulently flows through the chamber.
An apparatus for texturing a yarn product comprising:
- a liquid jet arrangement arranged in a filament spinning apparatus and adapted to apply to the yarn product traveling along a yarn path through the jet arrangement a force transversely to the axis of the yarn product, wherein the jet arrangement is disposed downstream of a fluid cooling arrangement, wherein the cooling fluid is a liquid, and wherein the liquid jet arrangement and the cooling arrangement have a common liquid.
