本文係以不同基重之紡粘法聚酯纖維不織布為材料，經撥水處理後，來改善目前溫室常使用之防水效果不良的黑色格網為被覆材之缺點。在研究中針對撥水劑的效果及被覆角度的改變來進行探討。由實驗結果得知，不織布之被覆角度越小，其防雨性越佳；並且在所加的各式撥水劑中以氟素高分子化合物效果最佳，其次為矽油乳化物。
The nonwovens with different basis-weights made of spunbonded polyster fiber were used. These nonwovens were treated using water repellentcy to improve the disadvantages of the black sunblind empolyed as covering material for the Greenhouse. The effect of various water-repelling agents and the change of the coating angles on the waterproof properties of the nonwovens treated was investigated in this study. The results show that the smaller the coating angle, the better the waterproof property of nonwoven. The fluorine-contained agent has the best performance between the water-repelling agents, and the silicon-oil emulgent is the second.
