PET heat setting short fiber needle punched nonwoven geotextile

PET heat setting short fiber needle punched nonwoven geotextile

 1.UsageUsed in the area of highway, railway, dam, lam fencing for filtration, separation drainage and protection.Also can be used as carpet in the car, for the cloth liner, glove, cleaning cloth, shoes liner.etc.2..Applications of geotextileA.FiltrationThe filtration layer of the dykes, river canal, seacoast, concrete slope, retaining walls. At the same time of preventing the clay granule from passing, it allows the water and the gas pass through freely.B. SeparationThe isolation of the railway dregs and the roadbed, roadbed and the soft base, surface of the airdrome and parking lot and the groundsill, different dam materials. It isolates the soil and the gravel of two kinds different granule pathway from the groundsill or other buildings. C. Adding muscleThe highway, railway, soil-stone dam, breakwater, airport, backfill soil of retaining wall, slope protection, etc in which distributes the earth stress, prevents the side-displacement of the earth body and improves the earth body stability. D.Protection It prevents the bank from being washed out, protects the bank and the bottom, prevents the water and soil from being washed away.3.Specification100GSM—800GSM4..PropertyGood flexibility,permeability,filtration, separation and easy for construction.

5.Size of packageWidth 2m-6m,length 50-100m (or at request).

6. Geotextile joints to connectGeneral Geotextile joints to connect there is overlap, welding and oversew three ways.Note:If geotextile joints to connect on the flat ground, overlap width30cm.If geotextile joints to connect not on the flat ground, overlap width50cm.
