Abstract
A method of inserting a fill yarn on an air jet loom includes propelling a fill yarn with one or more air jets from the insertion side to the exit side of the loom, where the yarn comprises a strand of individual filaments, the strand having a primary cross-sectional shape and periodic flat spots with a flat cross-sectional shape which is more elongated than the primary cross-sectional shape, and where the flat spots provide increased drag for propulsion by the air jets.
Claims18
The method of inserting a fill yarn on an air jet loom comprising providing fill yarn in the form of a strand of individual filaments, the strand having a primary cross-sectional shape and periodic flat spots with a flat cross-sectional shape which is more elongated than the primary cross-sectional shape, propelling the fill yarn with one or more air jets from the insertion side to the exit side of the loom, and where the flat spots provide increased drag for propulsion by the air jets.
The method of inserting a fill yarn on an air jet loom comprising providing fill yarn in the form of a strand of individual filaments, the strand having a primary cross-sectional shape having an aspect ratio within the range of from about 1:1 to about 1:6, and the strand having periodic flat spots with a flat cross-sectional shape which has an aspect ratio greater than about 1:6, propelling the fill yarn with one or more air jets from the insertion side to the exit side of the loom, and where the flat spots provide increased drag for propulsion by the air jets.
The method of inserting a fill yarn on an air jet loom comprising providing fill yarn in the form of a strand of individual filaments, the strand having a primary cross-sectional shape having an aspect ratio within the range of from about 1:1 to about 1:6, and the strand having periodic flat spots with a flat cross-sectional shape which has an aspect ratio within the range of from about 1:50 to about 1:6, where the width of the flat spots is within the range of from about 5 to about 20 times the width of the primary cross-sectional shape, where the length of the flat spots is within the range of from about 0.5 to about 10 cm, where the period of the flat spots is within the range of from about 0.2 to about 6 meters, propelling the fill yarn with one or more air jets from the insertion side to the exit side of the loom, and where the flat spots provide increased drag for propulsion by the air jets.
