非織造無紡土工(gong)布的原(yuan)(yuan)料來源廣泛，包括滌綸(lun)、丙綸(lun)、錦綸(lun)、乙烯基和一些纖維，其中滌綸(lun)和丙綸(lun)由于價格(ge)低廉、性能好成為應用廣泛的原(yuan)(yuan)材料。

　　目前在我(wo)國，滌(di)綸(lun)無紡(fang)土(tu)工布(bu)(bu)是工程中應用廣泛的土(tu)工布(bu)(bu)滌(di)綸(lun)非織造土(tu)工布(bu)(bu)具有高(gao)(gao)強度、高(gao)(gao)熔點(dian)、良的韌性和(he)蠕變特(te)性，特(te)別是在抗紫外線和(he)抗老化性能(neng)方面，可以滿足工程要(yao)求。

　　但滌綸非織(zhi)造土工(gong)布也存在一定的缺點，如耐(nai)酸(suan)堿性能差(只有(you)耐(nai)弱酸(suan)、耐(nai)強酸(suan)和(he)弱堿才能使其分(fen)解)、熱收縮(suo)率大(da)、尺寸穩定性差等，限(xian)制了(le)其工(gong)程應用范圍。

　　與(yu)滌(di)綸(lun)無(wu)紡(fang)土(tu)工(gong)(gong)(gong)(gong)布相比，丙(bing)(bing)綸(lun)無(wu)紡(fang)土(tu)工(gong)(gong)(gong)(gong)布具有(you)高的(de)強度、好(hao)的(de)耐酸(suan)堿、耐磨、耐腐蝕、防霉(mei)變和好(hao)的(de)吸水效果(guo)。丙(bing)(bing)綸(lun)的(de)密(mi)度比滌(di)綸(lun)小30%，當丙(bing)(bing)綸(lun)無(wu)紡(fang)土(tu)工(gong)(gong)(gong)(gong)布與(yu)滌(di)綸(lun)無(wu)紡(fang)土(tu)工(gong)(gong)(gong)(gong)布的(de)固定重量相同(tong)時，丙(bing)(bing)綸(lun)無(wu)紡(fang)土(tu)工(gong)(gong)(gong)(gong)布的(de)纖維較多，其排水性(xing)(xing)和平(ping)排水性(xing)(xing)較好(hao)。由于這些特(te)性(xing)(xing)，聚(ju)丙(bing)(bing)烯(xi)(xi)無(wu)紡(fang)土(tu)工(gong)(gong)(gong)(gong)布在酸(suan)性(xing)(xing)地下(xia)環(huan)境和嚴寒等惡劣環(huan)境中具有(you)滌(di)綸(lun)無(wu)紡(fang)土(tu)工(gong)(gong)(gong)(gong)布不可替(ti)代的(de)地位。但聚(ju)丙(bing)(bing)烯(xi)(xi)抗紫(zi)外線(xian)性(xing)(xing)能較差，限制了聚(ju)丙(bing)(bing)烯(xi)(xi)非織造土(tu)工(gong)(gong)(gong)(gong)布在其應用領域的(de)應用。目前，在我(wo)國，工(gong)(gong)(gong)(gong)程中很(hen)少(shao)使用聚(ju)丙(bing)(bing)烯(xi)(xi)無(wu)紡(fang)土(tu)工(gong)(gong)(gong)(gong)布。
