3, press code requirement, sutural anti-aging and corrosion resistance requires to reach the level of non-woven geotextile.In actual applications, the suture that reaches this requirement is difficult to find on market; Because sutural consumption is little, also is not suitable for confirming that as special detection it is anti-aging, corrosion resistance reaches requirement.In addition, even suture is anti-aging, the corrosion resistance ability is identical with non-woven geotextile,, aging, the corrosion relative velocity is fast because suture is trickleer.Under sun exposure, be easy to just wear out, easily fracture.
4, for for a long time exposed non-woven geotextile of needs, as the soot side slope top layer geotextiles of landfill waste not, big slit is arranged between the suture, wind passes from the slit when blowing, and enters the nonwoven fabric below geotextiles is lifted.
As meeting with aging seam, can cause non-woven geotextile to tear when 5, blowing from the seam large tracts of land, stripping, thus cause heavy losses.
Because the defective that the joint construction of above-mentioned existing non-woven geotextile exists, the design people is actively studied innovation, in the hope of founding a kind of non-woven geotextile of new structure, makes it have more practicality.
