土工布按照生產(chan)工藝如何分(fen)類：

土工布按制造方法不同，分為織造土工布（有紡(fang)）、非織(zhi)造土(tu)工(gong)布(bu)（無紡(fang)）、復合型土(tu)工(gong)布(bu)、濕法成網土(tu)工(gong)布(bu)。其中：

1、織造(zao)土工(gong)布(有紡)由合(he)成(cheng)纖(xian)維(wei)長絲(si)（丙綸、滌綸、錦綸、維(wei)綸、乙綸等）或(huo)塑料扁絲(si)、塑料裂膜絲(si)按(an)一定方向排(pai)列機織的土工(gong)織物；

2、非織造土工(gong)布（無(wu)紡）由短(duan)纖(xian)維或(huo)(huo)長絲(si)按隨(sui)機排列(lie)或(huo)(huo)定向排列(lie)制(zhi)成的薄絮墊(dian)，經機械結合、熱粘或(huo)(huo)化粘而(er)成的織物(wu)；

3、濕法成網土工(gong)布由短切聚酯纖維(wei)、玻璃纖維(wei)為原料(liao)在水中分散后，經抄取、脫水、施膠(jiao)、干燥等(deng)工(gong)藝過(guo)程(cheng)制造而(er)成；

4、復(fu)(fu)(fu)合(he)型土(tu)(tu)工(gong)布(bu)：以聚合(he)物為原料制成的(de)(de)長絲機(ji)織(zhi)土(tu)(tu)工(gong)布(bu)或裂膜絲機(ji)織(zhi)土(tu)(tu)工(gong)布(bu)（編織(zhi)土(tu)(tu)工(gong)布(bu)）與短纖(xian)針刺非(fei)織(zhi)種土(tu)(tu)工(gong)布(bu)經(jing)針刺復(fu)(fu)(fu)合(he)而成的(de)(de)土(tu)(tu)工(gong)織(zhi)物。具有(you)防護、加筋功能(neng)，主要用于軟土(tu)(tu)地基(ji)加筋補強、路堤基(ji)底加筋等工(gong)程(cheng)領域中。按產品(pin)結(jie)構分為二層復(fu)(fu)(fu)合(he)和三(san)層復(fu)(fu)(fu)合(he)。

5、土工布按原料不同，分為 ① 滌綸短纖針刺非織造土工布；② 聚丙烯短纖針刺非織造土工布；③ 聚酯長絲紡粘針刺非織造土工布；④ 丙綸長絲機織土工布；⑤
滌綸長絲(si)機織(zhi)土工(gong)(gong)(gong)(gong)布；⑥玄(xuan)武巖纖(xian)維機織(zhi)土工(gong)(gong)(gong)(gong)布；⑦聚丙烯(xi)裂膜絲(si)機織(zhi)土工(gong)(gong)(gong)(gong)布；⑧ 塑料(liao)扁絲(si)編織(zhi)土工(gong)(gong)(gong)(gong)布；⑨ 聚酯玻纖(xian)濕法(fa)非(fei)織(zhi)造(zao)土工(gong)(gong)(gong)(gong)布；⑩營養土工(gong)(gong)(gong)(gong)布。

6、復合土工布按材質組成分為：①長絲機織/短纖非織造復合土工布（FW/SNG)；②裂膜絲機織/短纖非織造復合土工布（SWG/SNG)；③
塑料扁絲編織/短纖非織造復合土工（GFW/SNG)；④ 短纖非織造/長絲機織/短纖非織造復合土工布（SNG/FW/SNG)；⑤
短纖非織(zhi)造/裂膜絲(si)機織(zhi)/短纖非織(zhi)造復(fu)合土工布（SNG/SWG/SNG)；⑥ 短纖非織(zhi)/塑料(liao)編(bian)織(zhi)扁(bian)織(zhi)/短纖非織(zhi)造復(fu)合土工布（SNG/SWG/SNG)。
