本研究係以聚酯纖維與嫘縈纖維為原料，經各種不同比例混合後再經高溫壓縮定 型作成固定體積之纖維集合體，進而探討其適用於無土栽培上之各項特性。由實驗結果顯示， 纖維集合體之密度在0.045g/cm�蠔伓�適用於無土栽培介質所要求之各項特性。而嫘縈纖維 所含比率，會影響其液相體積分率，體積變形率，氣相體積分率，孔隙率與水分散失速率。
This research is using polyester fiber and rayon fiber as material. Using rayon fiber to increase the water phase percent. After being mixed in different percentage, samples are compressed into a fixed volume by high temperature. We discuss the suitability on soildless culture medium. The research shows that when the density of fiber group is at 0.045 g/cm��, it is more suitable for soildless culture medium. The rayon percentage effects the water phase percentage, pore space percent, air capacity percent, volume reducing percent and water losing percent.
