Process for the flame-retardant treatment of textiles

摘要: A process for the flame-retardant treatment of a cellulosic fabric by impregnating with an aqueous solution tetrakis (hydroxyorgano) phosphonium (THP) and then at least partially drying it. The dried impregnated is passed speed 30 to 100 m/minute once through chamber containing ammonia single cure. Both moisture contained in water produced as by-product curing are volatilized condensed on interior wall flow down walls drain removal from apparatus. further includes measuring rate gas fed into chamber, determining content temperature within maintaining initial concentration 70% 90% volume ratio input THP composition range 1.2 1, basis phosphorus; withdrawing treated removing some chamber; recycling back chamber.
