本研究利用雙螺桿混煉機將磷系阻燃劑HM1100與PET進行熔融混摻，製成共混物，再利用TGA與DSC測試其熱性質，並以熱壓成型將其製成燃燒試片，進行UL94燃燒等級測試與LOI實驗。UL94燃燒等級測試可了解其阻燃性質以及是否產生熔滴與否，LOI可知其最低燃燒氧指數，其值越大表越不易燃燒、阻燃性質越好。POE-g-MA為polyethlyene-octene elasomter (POE)接枝maleic anhydride (MA)之共聚物(copolymer)，可增進阻燃劑與PET的分散性，亦可作增塑劑以增加其塑性，在PET與阻燃劑HM1100共混物內添加後可提升其流動性質，更利於加工，且能使共混物在燃燒後達到抗熔滴的效果。再將混摻物利用Melt Index測量其流動性質，由此結果可作為是否能進行熔融紡絲試驗的參考。最後我們利用sheath and core的方式進行紡絲測試且測試其纖維強度，再將紡絲纖維製成織襪帶且作物性強度以及LOI的測試。

In this study, the phosphorus flame retardant HM1100 was blended with PET using a twin-screw blender. Thermal properties of the blends were measured by TGA and DSC. Hot press was used to prepare flame film. Flame tests and flame retardant properties of the blends were performed according to the specifications of UL94 and LOI. POE-g-MA is a graft copolymer of polyethylene-octane elastomer (POE) and maleic anhydride (MA) that compatibilized the flame retardant and PET. POE-g-MA also served as a plasticizer in the blend to increase the flow properties, facilitating the processing of the blend. On combustion, the blend can achieve anti-droplet. Melt index was measured to represent flowability of the blends for the melt spinning. Finally, sheath and core spinning were performed and the strength of the resultant fiber was measured. Textile samples were woven from the fibers and werer characterized with physical strength and LOI test.
