  • Patent number: 4042737
    Abstract: Process for the production of a crimped metal-coated continuous-filament or a crimped yarn of a plurality of metal-coated filaments which filament or yarn is adapted for combination with other filaments to form an improved yarn for use in making anti-static fabrics, such as pile carpets or the like, wherein the continuous-filament or yarn comprising a plurality of filaments is first made into a knitted fabric, the fabric is treated to deposit a continuous metal coating on the filament or yarn thereof, and the coated fabric thus obtained is deknitted, thereby yielding the metal-coated continuous-filament or yarn in a crimped disposition characteristic of the knitted loop construction existing in the knit fabric. Heat treatment of the crimped filament or yarn after the metal-coating step significantly improves its anti-static properties when incorporated into fabric.
