Abstract:	目前國內的不織布工業中，以聚酯及聚丙烯不織布的產量最多；相對的，它所造成的廢料也最多。為了達到回收紡織廢棄物與環境保護的目的，我們擬回收聚酯與聚丙烯不識布之廢邊，並且將之再製成複合板材。在本研究中我們改變了熱壓時間、熱壓溫度以及篩網孔徑大小等實驗參數，以探討製程參數對其機械性質之影響。研究結果顯示，在熱壓壓力固定為60kgf/cm^2的條件下，本研究之最佳製程條件分別為：熱壓溫度190~200℃，熱壓時間5~10分鐘，平板的抗拉強度最大可達17MPa，而其抗拉伸度最大約為7%同時我們也發現，碎片顆粒的大小對平板的拉伸性質之影響並不顯著，這表示了板材的成形條件對其拉伸性質之影響，較其顆粒大小的分布更為重要。 The production and consumption of polyester and polypropylene nonwovens are the most, and so are their wastes. For recycling of textile wastes and environmental preservation, we planned to recycle polyester and polypropylene nonwoven selvages and produce plastic composites. In this study we changed some parameters included compressing temperature, time and the bore diameter of mesh to discuss the influence on their tensile properties. The results revealed that the optimum conditions of the manufacturing process were 190~200℃ for 5~10 minutes at the constant compressing pressure of 60 kgf/cm^2. The tensile strength of the plastic composites was about 17 MPa and their elongation at break was about 7%. At the same time, the effect of fragment size was not obvious on the tensile properties of plastic composites. This shows that the effect of forming conditions of plastic composites on their tensile properties was more important than that of fragments size.
