Abstract
A method of delivering warp yarn into an air jet loom, comprising the steps of: providing a loom beam comprising warp yarn having a resin compatible coating; drawing warp yarn from the loom beam; contacting the warp yarn with a whip roll having a reduced surface area such that the warp yarn contacts at least a portion of the reduced surface area of the whip roll; and directing the warp yarn into an air jet loom. In one non-limiting embodiment of the invention, the reduced surface area of the whip roll is no greater than 50% of its equivalent surface and is textured, the reduced surface area of the whip roll includes a plurality of grooves, the warp yarn is a fine yarn provided at a warp yarn density of at least 50 yarns per inch and forms a warp shed, and a fill yarn having a resin compatible coating is inserted into the warp shed.
