Abstract: Jute fabric was coated with coating formulation containing blend of solid natural rubber, polyvinyl alcohol and starch in complete absence of solvent employing a calendar coating technique to produce moisture vapour permeable waterproof jute fabric. Coating of jute with a formulation containing solid natural rubber, solid polyvinyl alcohol and tamarind kernel seed powder as starch, in the ratio of 10:8:5 in presence of a typical sulphur curing system, followed by vulcanization at 140oC for 3 h employing steam produced most balanced improvements in the properties of the coated fabric in respect of waterproofness assessed in terms of hydrostatic water column resisted by fabric, , breathability as revealed by moisture vapour transmission rate ,coating adhesion, tensile properties, abrasion resistance and flex endurance. Incorporation of polyvinyl alcohol makes the coating permeable to moisture vapour and such property is promoted further in presence of starch in the coating formulation. Examination of surface morphology of vulcanized coating by scanning electron microscopy revealed that poly vinyl alcohol crystals formed clusters of dimensions of only few microns in the rubber matrix. Such clusters of polyvinyl alcohol served as conduits for transportation of moisture vapour through the film of natural rubber, while acting as an effective barrier for liquid water droplets.
