High Strength Needle Punched Geotextile

Needle Punched Geotextile This geotextile uses polyester fibers or polypropylene fibers as raw material. It is produced with a needle-punch process. Fibers entangle with each other. Surface density is fairly uniform. Overall thickness is moderate. No other ingredients are added. The fibers themselves are common types. The needle-punch process does not use heat. Mechanical force makes fibers hold together. The fabric has no obvious warp or weft lines. It feels somewhat like felt. Thickness is not perfectly consistent. But batch-to-batch variation is small. Color is usually white or black. It depends on whether color masterbatch is added to the raw material. Polyester fibers and polypropylene fibers have different characteristics. Polyester fibers are slightly stiffer. Polypropylene fibers are lighter. Both are usable. Users choose according to project requirements. Needle punch density can be adjusted. Higher density makes the fabric tighter. Lower density allows faster water flow. Du…
