Abstract
An article of clothing having at least one layer of a fabric or a fabric having an aramid yarn knitted or woven with a heat settable yarn. The fabric is heated to set the heat settable yarn thereby dimensionally stabilizing the fabric without bonding. The fabric may be a scrim or a lining having a facing material laminated thereon.
Claims21
An article of clothing comprising at least one layer of fabric having a single constituent aramid fiber yarn and a separate heat settable synthetic fiber yarn, said yarns being interrelated to form said one layer of fabric and said heat settable yarn being heat set to dimensionally stabilize said one layer of fabric without bonding said aramid fiber yarn to said heat settable yarn.
A dimensionally stabilized fabric comprising a first yarn interrelated to a second yarn to form said fabric, said first yarn being a single constituent aramid fiber yarn and said second yarn being a heat settable synthetic fiber yarn, said second yarn being heat set to dimensionally stabilize the fabric without bonding.
A method for forming a dimensionally stabilized fabric having a single constituent aramid fiber yarn comprising interrelating aramid fiber yarns with a heat settable synthetic fiber yarn to form a desired fabric and heat treating said fabric at a temperature for a sufficient amount of time to heat set said heat settable yarn whereby said fabric is dimensionally stabilized without bonding.
