Abstract
There is disclosed a method of texturing yarn products wherein the yarn product is passed along a predetermined yarn path through a liquid jet device applying a force to the yarn transversely to the axis thereof, comprising directing the liquid as it passes through the liquid jet device past an air inlet to the liquid jet device to entrain air therein.
Claims59
A method of texturing yarn products wherein a yarn product is passed along a predetermined yarn path through a housing with a yarn outlet, the method comprising:
- providing a housing with a yarn inlet and a yarn outlet, the yarn path passing through the housing and including a predetermined section within a texturing chamber defined by a body within the housing between a texturing chamber inlet end and a texturing chamber outlet end, the texturing chamber outlet end being spaced from the housing yarn outlet;
- and,
- applying a force to the yarn transversely to the axis thereof in the texturing chamber by directing a liquid at said yarn as it passes through the texturing chamber, the predetermined section of the yarn path passing an air inlet to entrain air in liquid in the chamber.
Apparatus for texturing yarn comprising:
- a housing with a yarn inlet and a yarn outlet defining a yarn path therebetween;
- a body within the housing defining a texturing chamber with a yarn inlet end and a yarn outlet end, and a yarn inlet thereto aligned with the yarn inlet to the housing;
- a liquid inlet to the body for directing a jet of liquid at yarn in said yarn path and in said body;
- an inlet for air to be entrained in liquid in the texturing chamber;
- and,
- an outlet for discharge of liquid from the housing, wherein the outlet end of the texturing chamber is spaced from the housing yarn outlet and from the discharge liquid outlet from the housing.
