An Improved SRRC No-Twist Yarn System

Progress has continued on the SRRC no-twist yam system since the work was originally announced at the 1979 Natural Fibers Textile Conference. Various me chanical modifications that have allowed the production rate to reach 1.5 m/second (100 yards/minute) are discussed. Yam properties of no-twist yarns made from three different staple length cottons at varying production rates are compared to ring spun and open-end yarns from the same cottons. These results show that the no-twist yams compare favorably in uniformity and grade, but are weaker with lower elongation than the ring or open-end yams. Properties for knitted jersey fabrics from selected no-twist yarns compare favorably with ring and open-end fabrics. Work is continuing on the experimental no-twist yarn system.
