Results of liquid ammonia treatment on jute yarns and fabrics are presented. Significant increase in elongation-at-break with some increase in tenacity has been observed in the case of jute yarns. As already reported for jute fibers, an optimum period of treatment of about ten minutes has been observed for jute yarns also. Liquid ammonia treatment increases the extension-at-break of jute fabrics also, and this results in significant improvement in tufting performance of the fabric. Pretreatment of jute fabric with liquid ammonia prior to application of Hame-retarding materials gives significant improvement in fire retardant properties.
