To test the durability of the finish wash fastness was evaluated and to maintain the durability, a laundry procedure was optimised. The flame retardant finish was developed by using the chemical Tetrakis (hydroxymethyl) phophoniun chloride (THPC) along with citric acid as binder and sodium hypophosphite as catalyst. The optimisation of pH, concentration of binder, concentration of catalyst and concentration of THPC was done by testing the effects of the finish at different variables on physical properties- tensile strength, flexural rigidity, thickness, GSM and whiteness index. The flammability was tested using Vertical Flammability tester. The results showed that for casement fabric, pH 7, binder concentration 10%, 0.75% concentration of catalyst and 30% concentration of THPC were considered optimum. On the other hand for the poplin fabric pH 8, binder concentration 8%, 0.75% concentration of catalyst and 40% concentration of THPC were considered optimum. At these conditions tensile strength decreased and flexural rigidity increased but in permissible limits. It was found that the developed finish was semi-durable and would last for 15-20 washing cycles. The optimised laundry procedure suggested that the flame retardant casement and poplin fabrics should be washed with non-ionic detergent with 2gm/L concentration at 25oC temperature to maintain its durability till 15-20 home launderings. The flame retardant fabrics were used for making household textile products such as kitchen apron, mitten, napkins and curtain.ennullThesis
