Nonwoven fabrics were made from jute broadloom caddis (raw and bleached), stapled raw jute, woollenized jute, viscose rayon, and their blends on a Callaghan nonwoven fabric machine, employing an air-laying technique of ran domization of fibers, followed by impregnation with bonding agent and curing. The properties of these fabrics were also measured so that their suitability for various uses could be examined.

The practicalities of blending viscose staple fiber with Tossa jute were investigated. A critical tossa jute :viscose blend proportion was found to exist at which yarn tenacity was minimum. For blended yams the optimum twist factor was practically constant at 25.0 (turns per cm × √tex), and irregularity was reduced as rayon proportion increased. Weaving efficiency and fabric quality showed improvements even with 10% viscose in the blend. The used of bleached jute in the blend increased whiteness at the loss of strength.
