M'mafakitale ambiri, monga makampani opanga mankhwala, magetsi, mafuta, makina, migodi, mayendedwe, ukhondo, zomangamanga ndi malo ena, antchito nthawi zambiri amafunika kuvala yunifolomu yoletsa moto malinga ndi zosowa za malo ogwirira ntchito.
Pali mitundu yosiyanasiyana ya nsalu zotchingira moto zomwe zimagwiritsidwa ntchito, monga aramid, viscose yotchingira moto ndi polyester yotchingira moto. Polyester yotchingira moto ndi yoyenera kwambiri chifukwa cha mtengo wake wotsika, koma polyester wamba yotchingira moto pamsika imasungunuka ndi kugwa ikawotchedwa ndi moto.
EMT imagwiritsa ntchito ukadaulo wosintha wa FR wopangidwa ndi copolymer kuti ipange zinthu za FR zopanda halogen mu unyolo waukulu wa kapangidwe ka mamolekyu a polyester kuti ipange FR co-polyester. Kupanga zinthu zopangira ndi ukadaulo wapadera, ndi luso lopanga nsalu ya polyester yoletsa moto, yomwe ndi yoletsa kudontha. Poyerekeza ndi zinthu wamba zomwe zili pamsika, magwiridwe antchito a choletsa moto ali ndi zabwino zambiri.
Nsalu ya polyester yoletsa madontho a moto iyi ingagwiritsidwe ntchito kupanga suti yogwirira ntchito ya lalanje ya FR yowoneka bwino kwambiri, mtengo wake ndi wopikisana kwambiri. Chiŵerengero chachikulu cha polyester ya FR mu nsaluyi chikhoza kufika 80%.
Nsaluyi yangopangidwa kumene pamsika, yopangidwa ndi ukadaulo watsopano. Tikuyipereka kwa makasitomala, kuti tiwonetse mawonekedwe ake abwino komanso odabwitsa.
