有紡土工布

有紡(fang)土(tu)(tu)(tu)工(gong)(gong)(gong)(gong)(gong)布(bu)(bu)是由至少兩(liang)組平行的(de)紗(sha)線（或扁絲(si)）組成，一(yi)組沿織(zhi)機的(de)縱（織(zhi)物行進的(de)方向）稱經紗(sha)，另一(yi)組橫(heng)向布(bu)(bu)置(zhi)稱為(wei)緯(wei)紗(sha)。用(yong)不(bu)(bu)同(tong)的(de)編制(zhi)編織(zhi)設備和工(gong)(gong)(gong)(gong)(gong)藝(yi)將經紗(sha)與緯(wei)紗(sha)交織(zhi)在(zai)一(yi)起織(zhi)成布(bu)(bu)狀(zhuang)，可(ke)根據(ju)不(bu)(bu)同(tong)的(de)使用(yong)范圍編織(zhi)成不(bu)(bu)同(tong)的(de)厚度與密(mi)實(shi)度，一(yi)般(ban)(ban)有紡(fang)土(tu)(tu)(tu)工(gong)(gong)(gong)(gong)(gong)布(bu)(bu)較薄縱橫(heng)向都(dou)具(ju)有相當(dang)強的(de)抗(kang)拉強度（經度大于(yu)緯(wei)度），具(ju)有很好的(de)穩定性能(neng)(neng)。有紡(fang)土(tu)(tu)(tu)工(gong)(gong)(gong)(gong)(gong)布(bu)(bu)根據(ju)編織(zhi)工(gong)(gong)(gong)(gong)(gong)藝(yi)和使用(yong)經緯(wei)的(de)不(bu)(bu)同(tong)分為(wei)加(jia)(jia)筋(jin)土(tu)(tu)(tu)工(gong)(gong)(gong)(gong)(gong)布(bu)(bu)和不(bu)(bu)加(jia)(jia)筋(jin)土(tu)(tu)(tu)工(gong)(gong)(gong)(gong)(gong)布(bu)(bu)兩(liang)大類，加(jia)(jia)筋(jin)土(tu)(tu)(tu)工(gong)(gong)(gong)(gong)(gong)布(bu)(bu)的(de)經向抗(kang)拉強度遠遠大于(yu)普通土(tu)(tu)(tu)工(gong)(gong)(gong)(gong)(gong)布(bu)(bu)。有紡(fang)土(tu)(tu)(tu)工(gong)(gong)(gong)(gong)(gong)布(bu)(bu)一(yi)般(ban)(ban)實(shi)際應用(yong)與土(tu)(tu)(tu)工(gong)(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)(gong)程項目(mu)的(de)加(jia)(jia)筋(jin)增強，主要(yao)功能(neng)(neng)是加(jia)(jia)固增強，具(ju)有平面(mian)隔離與保護功能(neng)(neng)，不(bu)(bu)具(ju)備平面(mian)排水(shui)功能(neng)(neng)可(ke)根據(ju)具(ju)體(ti)的(de)使用(yong)目(mu)的(de)選用(yong)。

土(tu)工布，又稱土(tu)工織物，它是由(you)合成(cheng)纖維(wei)通過針(zhen)刺(ci)或編織而成(cheng)的透水性土(tu)工合成(cheng)材料(liao)。土(tu)工布是新材料(liao)土(tu)工合成(cheng)材料(liao)其中的一種，成(cheng)品為布狀，一般寬度為4-6米(mi)，長度為50-100米(mi)。土工布分(fen)為有紡(fang)土工布和(he)無紡(fang)長絲土工布。

土工布特點:

1、強力高，由于使用塑(su)料纖維，在干濕狀態下都能保持(chi)充分(fen)的強力和(he)伸長。

2、耐腐(fu)蝕(shi)，在不同(tong)的酸(suan)堿度的泥土及水中能長久地(di)耐腐(fu)蝕(shi)。

3、透水(shui)(shui)性好(hao) 在纖維間有空隙，故有良(liang)好(hao)的滲水(shui)(shui)性能。

4、抗微生(sheng)物性好 對微生(sheng)物、蟲蛀均(jun)不(bu)受損害。

5、施工方便(bian)，由于材質輕、柔，故(gu)運送、鋪(pu)設、施工方便(bian)。

6、規格(ge)齊全： 幅寬可達(da)9米。是國內寬產(chan)品，單位(wei)面積質量：100-1000g/m2
