ʻO ka fiber pōkole ʻAʻole i ulana geotextile he ʻano hana hana hou i hoʻohana ʻia i ka ʻenekinia kīwila.Hana ʻia ia me nā fibers PP a i ʻole PET e nā kaʻina hana kuʻi.ʻOi aku ka kiʻekiʻe o ka ikaika tensile o PP non woven geotextile ma mua o ka PET non woven.Akā ʻo lāua ʻelua he pale waimaka maikaʻi a he hana nui hoʻi: kānana, hoʻokahe a me ka hoʻoikaika.Loaʻa nā kikoʻī mai ka 100 grams no ka mika square a i ka 800 grams no ka mika square.
Nā hiʻohiʻona huahana:
1. He mea hale pili kaiapuni.
2.Good mechanical properties, maikaʻi wai permeability, corrosion kū'ē a me kaʻelemakule kū'ē.
3.Strong anti-kunu a me ka anti-corrosion hana, fluffy hale a me ka maikai drainage hana.
4.Good friction coefficient a me ka ikaika tensile, a he hana hoʻoikaika geotechnical.
5.Good ka hoʻomau holoʻokoʻa, ke kaumaha māmā a me ke kūkulu kūpono
6. He mea pervious ia, no laila he kānana maikaʻi a me ka hana hoʻokaʻawale a me ke kūpaʻa puncture ikaika,
no laila he hana pale maikaʻi.
