中文摘要 | 本研究中,聚酯╱聚醯胺(PET/Nylon)複合超細纖維非織物是利用水軋法備製而成地。非織物中複合超細纖維的開纖程度,非織物的強伸度,抗彎剛度都與製程中水軋能量有關。SEM照片顯示,在水軋能量低於72kw/lm時,聚酯╱聚醯胺複合纖維僅部份開纖;當能量為72kw/lm時,複合纖維大部份都已開纖;當能量到達98kw/lm時,複合纖維幾乎已完全開纖化。值得注意的是非織物的拉伸強度與抗彎剛度在72kw/lm有一轉折現象存在,這現象可能是當水軋能量為72kw/lm時,能量大部份供給纖維的開纖化而無法提供纖維之間的糾結。故在提供更高的水軋能量時,纖維之間開始糾纏,而促使非織物的拉伸強度及抗彎剛度提高。 |
英文摘要 | In this study, the PET/Nylon ultrafine microfibre nonwoven fabric was prepared which then splitted by water jet method. Results obtained from the fiber splitting level, tensile properties, water absorption, and bending rigidity of produced nonwoven fabric were correlated with the water jet energy. According to SEM photographs, when the jet energy was smaller than 72kw/lm, the conjugate fibers were only partially fibrillated. At the energy level of 72kw/lm, the fibres were mostly fibrillated. When the energy reached 98kw/lm, nearly all of the conjugate fibers were splitted. It was note that the strength and bending rigidity dropped at the energy level of ca. 72kw/lm before rising again. A possible explanation was that the fibers fibrillated at 72kw/lm without much entanglement, at higher energy levels, the excessive energy caused the fibrillated fibers to entangle and thus increased the strength and bending rigidity. |
