Abstract
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.
Claims20
A cut resistant, abrasion resistant, electrically conductive composite yarn for making protective garments comprising a core and a serving wrapped on said core, wherein said core is a substantially torque-free continuous filament metallic yarn of at least about 60 ends, each fiber in said metallic yarn has a diameter of not more than about 25 .mu.m, and said serving comprises at least one non-metallic fiber.
A cut resistant, abrasion resistant, electrically conductive, low torque composite yarn for making protective garments comprising a composite twist of a first, metallic yarn and at least one second, non-metallic yarn, wherein said first, metallic yarn is a continuous filament metallic yarn of at least about 60 ends having a twist in a direction opposite to the twist of said composite twist, and each fiber in said metallic yarn has a diameter of not more than about 25 .mu.m.
