Cut resistant, abrasion resistant and electrically conductive yarns ( ) are formed in torque-free form from stainless steel and other metallic yarns ( ) served with or formed into composite twists with non-metallic yarns and fibers ( ) and ( ). The metallic yarn ( ) is made up of at least about ends, and up to as many as about ends, of metal fibers ( ) having a diameter of from about to about &mgr;m. The absence of torque permits facile knitting into protective garments, such as cut resistant, abrasion resistant and/or electrically conductive gloves ( ), or yarns which are as much as to % by weight metallic fiber. When knit into gloves, added protection may be provided from puncture injuries if the palm ( ), finger stalls ( ) and thumb stall ( ) are coated or impregnated with an elastomer or the like.

Stainless steel yarn and protective fabric

Cut resistant, abrasion resistant and electrically conductive yarns (1) are formed in torque-free form from stainless steel and other metallic yarns (2) served with or formed into composite twists with non-metallic yarns and fibers (4) and (5). The metallic yarn (2) is made up of at least about 60 ends, and up to as many as about 300 ends, of metal fibers (3) having a diameter of from about 2 to about 25 .mu.m. The absence of torque permits facile knitting into protective garments, such as cut resistant, abrasion resistant and/or electrically conductive gloves (10), or yarns which are as much as 85 to 90% by weight metallic fiber. When knit into gloves, added protection may be provided from puncture injuries if the palm (12), finger stalls (14) and thumb stall (16) are coated or impregnated with an elastomer or the like.
