Coex is a biopolymer with flame-retardant properties derived from the functionalization of cellulosic fibers such as cotton, linen, jute, cannabis, coconut, ramie, bamboo, raffia palm, stipa, abacà, sisal, nettle and kapok. The treatment effectiveness was also proven on wood and semi-synthetic fibers such as cellulose acetate, cellulose triacetate, viscose, modal, lyocell and cupro. in 2015 the World Textile Information Network (WTiN) declared Coex the winner of the "Future material award" as best innovation for the Home Textile category.
