本研究的目的是提供另一種無土栽培介質的選擇和聚酯纖維回收後的再利用。方法是將聚酯非織物切成粒狀經高熱烘烤後再測其物性，結果顯示樣本約20min內吸水達飽和；EC值是1.6ms，pH值是6.5；在總體密度0.65~0.95g/cm□，液相分率是32.9%~37.8%，氣相分率是42.5%~53.2%，符合一般植物栽種環境條件。
The purpose of the study is to supply another choice of the soilless culture medium and to recycle polyethylene fiber. The method is to cut the polyethylene nonwoven cloth to be a lot of granule and to bake, then to measure the specimen's physicality. The result shows that in 20 minutes. sample is full of water. EC value is l.6ms and pH value is 6.5. Liquid percentage is among 32.9%-37.8%. air percentage is among 42.5%-53.2%.
