Textured surface effect fabric

摘要

Tufting apparatus includes servomotors driving front and back yarn feed rolls for feeding yarns to the needles of the front and back needle bars, respectively. Incremental servomotor control for each stitch enables a height differential between immediately adjacent stitches in excess of +E,fra 3/32+EE inch (2.38 mm). By providing yarns of multiple colors and textures, a variety of patterns and textured surface effects are provided in the surface of the tufted pile fabric.
