Abstract
An apparatus and method of using the same are presented for commingling synthetic multifilament yarns such as polyester or the like. The apparatus includes a pair of spaced apart fluid jets which direct air at an acute angle from different directions to the moving yarn to distort and mesh the filaments. The first fluid jet is directed in a forward direction (with the yarn travel) whereas the second jet is in a reverse or opposing direction to the yarn path. The method utilizes compressed air and a high velocity yarn to form nips therealong at approximately 10 to 14 millimeter spacings to create a commingled yarn which is cohesive for use on high speed looms and for other operations.

Apparatus for commingling yarn, said apparatus comprising:
- a first fluid jet, a second fluid jet, said first jet spaced from said second jet, said first and second jets positioned along a yarn path to direct fluid against yarn passing therealong, said first fluid jet having a fluid outlet disposed at an acute angle relative to the perpendicular of said yarn path, said second fluid jet having a fluid outlet disposed at an acute angle relative to the perpendicular of said yarn path, said first jet fluid outlet angularly disposed in the direction of the passing yarn, and said second jet fluid outlet angularly disposed in an opposite direction to the passing yarn.
Apparatus for continuously commingling multifilament yarn directed along a path, said apparatus comprising:
- a first fluid jet, said first fluid jet defining a first fluid outlet directed toward the yarn path at an acute angle relative to the perpendicular of the yarn path, said first fluid outlet directed along the travel path of the yarn, a second fluid jet, said second fluid jet defining a second fluid outlet directed toward the yarn path at an acute angle relative to the perpendicular of the yarn path, said second fluid outlet directed against the travel path of the yarn, a manifold, said first and said second fluid jets in fluid communication with said manifold, said first jet spaced from said second jet along said yarn path.
A method for commingling multifilament yarn by a pair of fluid jets positioned to direct fluid against the yarn in opposing directions comprising the steps of:
- (a) passing the yarn along a prescribed path;
- (b) directing fluid from a first fluid jet against said yarn at an acute angle relative to the perpendicular of the yarn path, the first fluid jet being directed along the yarn path;
- and
- (c) subsequently directing fluid from a second fluid jet against said yarn at an acute angle relative to the perpendicular of the yarn path to thereby commingle the yarn, the second fluid jet being directed against the yarn path.
