Fire is an important natural element. Fire has numerous constructive uses in both household and industries. The safety of human beings has become an issue of concern with rapid industrialization. To achieve the objective of the study, 100% white mercerized cotton fabric, Zirconium dioxide as flame retardant (FR) chemical (12% and 15%) and two binders .lamely SLN and PYA (5% each) and (2.5% each) were selected on review basis and used separately and in combination. Recipe was made on the weight of the fabric for making suspension of FR finish. To apply flame retardant fmish, pad-dry-cure method on padding mangle was used with 1 dip 1 nip, 2 dip 1 nip and 3 dip 1 nip systems. After application of FR finish, launderings was done 5, 10 and 15 times. Burning and flammability characteristics were assessed of treated and washed fabrics. Results interpret that after launderings, 5 per cent PYA binder gave best results with 15 per cent concentration of finish as compared to SLN binder. Flame resistance property of a material of exhibiting reduced flammability, it will not continue to burn or support a flame, but once ignited, it may continue to glow after source of ignition is removed. Flame retardant fabrics can be produced in two ways: 1. By making them of fibers which do not burn. 2. By chemically treating the fibers to produce the desired effect. Even after many decades of research and studies, the production of flame retardant textile is still a challenging subject. Every year thousands of people die of burns in India. India has had several tragedies due to fire in public places. Flame retardants reduce the likelihood of a fire starting by improving the resistance to ignition of potential fire sources. There is no doubt that they play an important role on textiles by providing safety and giving escape time from a potentials hazard. When a fire does start, flame retardants reduce the flame spread and the rate of fire development, providing valuable extra time in the early stages of the conflagration to extinguish the fire or make an escape. In abroad many studies have been done related to this area but not much work has been done in India. The present work on flame retardant finish on cotton is perhaps one of the vel3z few attempts made in this direction. Keeping this in mind present study has been investigated to assess the flammability characteristics of FR treated cotton fabric after launderings. [ABSTRACT FROM AUTHOR] |
