Jute fabrics develop wrinkle resistance to a satisfactory level through cross linking with common reagents like urea formaldehyde, melamine formaldehyde, dimethylol ethylene urea and dimethylol dihydroxyethylene urea in the presence of catalysts. The changes in properties of jute fabric, particularly the wrinkle resistance and tensile strength at various conditions of concentration of resin-catalyst systems, duration and temperature of curing, etc., were examined. The results, when compared with those of cotton fabrics, indicate that there are some common trends of relationship between wrinkle resistance and tensile strength of jute fabric, but with some deviations in the latter. The results of crosslinking experiments with the above-mentioned resins, using inorganic salts as catalysts, are discussed.</span>
