Abstract
An investigation is reported in which treatment of bleached jute (Corchorus olitorius) fabric was carried out with melamine/formaldehyde in a pad/dry/cure process, with magnesium chloride hexahydrate used as catalyst. The percentage resin add-on, total resin content, bound-nitrogen content, and bound-formaldehyde content of the treated fabrics were determined. Various physical properties of treated fabrics having different values of resin add-on were also studied and compared with those of the untreated fabrics. It was found that there exists a direct relationship between the resin add-on and (a) a significant improvement in the values of the dry and wet crease-resistance and (b) a reduction in the moisture-regain properties of the fabric. The losses in tensile strength and abrasion-resistance and the higher flexural rigidity of the fabric on treatment with the resin were found to be proportional to the level of applied resin on the fabrics.
