ABSTRACT:
A fine heterogeneous hybrid spun yarn is blended from electrostatically conductive staple fibers and electrostatically non-conductive staple fibers so that the yarn is electrostatically conductive only over short discrete lengths. When used in pile fabrics, such as carpets, the fine yarn is introduced with at least some of the carpet facing yarns during the carpet making operations. The resultant carpet structure substantially eliminates electrostatic shock to a human walking across the carpet and approaching a ground such as a light switch, radio, or another person. Such a carpet does not constitute a dangerous floor covering.
The unique heterogeneous hybrid spun blended yarn is achieved by process techniques completely contrary to accepted blending practices.
