What is THPC FR Functional

THPC-based  process, requires an ammonia gas curing in order to polymerize the applied finish into the internal fiber voids.
 
In this way the chemical condensate of tetrakis (hydroxy methyl) phosphonium chloride (THPC) and urea after padding and drying on to the fabric, is passed through a patented ammonia reactor which crosslinks the condensate to give an insoluble polymeric finish.
 
In order to increase the stability and hence durability of the finish, a subsequent phosphor oxidative “fixation” stage is required before finally washing off and drying.
