Purpose of this study is to establish improved conditions for PROBAN finish for both cotton and viscose fabrics with a special emphasis an the ammonia cure. The Fabrics thus finished were compared with those of Pyrobatex finish in their flame retardancy or other perfaramnces. In this study, the ammonia cure was effected by introducing ammonia gas into the evacuated curing chamber. Even 10 sec-exposure was found to be enough for the completion of ammonia cure. Cotton and viscose fabrics thus cured showed LOI values above 28, tensile strength as high as those of the unfinished samples and sufficient durability. The molar ratio of nitrogen: phosphorus was 2:1 and the critical amount of nitrogen for the flame retardancy was found to be 1.3-1.4 mmol/g. Formaldehyde was under the regulated level(75 μg/g sample).These were similar or better as compared with those finished by Albright & Wilson Co.
