本研究是以聚乙烯與聚丙烯複合纖維不織布為原料，製成吸水性管材，以期用於地下灌溉之管材時，能解決一般非吸水性管件之無法涵水、吸水之功能。並討論改變成形條件，對此種吸水性管件埋於土壤時，其透水性之影響。
The PE/PP bicomponent fiber nonwoven was used as the material to produce waterabsorbing pipe. In the study, in order to improve the ordinary poor functions of non-water- absorbing pipe such as one unable to embrace and absorb water and to ventilate when using on the irrigation pipe. We also discuss the influence of changing the molding condition on the air permeability of this kind of material.
