Abstract
A nappable, dimensionally stable fabric is produced on a three bar warp knitting machine by over feeding the yarns fed by the bottom bar to provide nappable loops, and by knitting the yarns fed by the top bar in a pattern providing nappable floats, longitudinal stability being provided by yarns knit from the middle bar, and lateral stability being provided by the partially napped floats.
Claims15
A double faced knit fabric having particular utility as a bedding blanket, said fabric being of at least three bar construction and comprised of:
- a support substrate of warp-knit yarns;
- a first facing of warp knit, overfed looped and napped yarns knit into said support substrate;
- and,
- an opposite facing of warp-knit napped floats of yarns, the yarns of said opposite facing being knit into said support substrate at the ends of the floats;
- the fibers of said substrate being substantially intact and unbroken, and providing longitudinal stability to said fabric;
- at least a portion of the fibers of said opposite facing being intact and unbroken and providing lateral stability to said fabric.
A method of forming a double faced knit fabric having particular utility as a bedding blanket, and which is comprised of:
- a support substrate of warp-knit yarns;
- a first facing of warp knit, overfed looped and napped yarns knit into said support substrate;
- and,
- an opposite facing of warp-knit napped floats of yarns, the yarns of said opposite facing being knit into said support substrate at the ends of the floats;
- the fibers of said substrate being substantially intact and unbroken, and providing longitudinal stability to said fabric;
- at least a portion of the fibers of said opposite facing being intact and unbroken and providing lateral stability to said fabric,
- said method comprising the steps of:
- warp knitting a support substrate on a middle bar of a knitting machine having at least three bars, the stitches of said substrate providing longitudinal stability of said fabric;
- simultaneously warp knitting a first facing into said substrate on a bottom bar of said knitting machine, the yarns of said first facing being overfed during the knitting of said first facing into said substrate and providing nappable loops;
- simultaneously warp knitting an opposite facing into said substrate on a top bar of said knitting machine, the yarns of said opposite facing providing nappable floats;
- and
- subsequently napping the yarns of both said facings to enhance the pile and loft fibers thereof, the extent of napping being such as to nap the facings alone in the substantial absence of any breakage of the fibers of said substrate, the napping being to an extent preserving sufficient of the fibers of the yarns of said opposite float facing intact and unbroken for them to provide lateral stability to said fabric.
