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. Liquid ammonia treatment increases the extension at break ofjute 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 flame-retarding materials gives significant improvement in fire retardant properties. -- AATA
