  • Patent number: 5287690
    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.
    Type: Grant

  • Patent number: 4519201
    Abstract: The present invention relates to an improved process for blending together textile like fibers exhibiting a relatively high modulus of elasticity together with textile fibers exhibiting a relatively low modulus of elasticity which blend can further be converted into a high quality blended yarn structure. When the textile fibers exhibiting the relatively high modulus of elasticity are also electrically conductive, such as e.g. metal or carbon fibers, then the resulting yarns and fabrics can be designed with a predetermined level of electrical conductivity.
