E like me kekahi ʻano o ka hoʻopaʻa ʻana i ke ahi, hiki ke hoʻohana ʻia i ka hoʻololi ʻana i ka lapalapa ahi mau loa o ka polyester, a ʻo ka spinnability o ka polyester pale ahi e like me PET, no laila hiki ke hoʻohana ʻia i nā ʻano ʻōnaehana wili a pau, me nā hiʻohiʻona e like me ka wela wela. paʻa, ʻaʻohe decompound i ka wā wili a ʻaʻohe ʻala. Hiki ke hoʻohana ʻia i nā kahua noi āpau o PET e hoʻomaikaʻi i ka mana antistatic o polyester. ʻO ke ʻano no ka copolymerization o PTA a me EG he 2.5 ~ 4.5%, ʻo ka phosphorus assay o ka flame retarding polyester sheet he 0.35-0.60%, a ʻo ka LOI o nā huahana retarding ahi he 30 ~ 36%.
