100% Polypropylene PP Staple Fiber Needle Punched Non Woven Geotextile

Description:

100% polypropylene Staple Fiber Needle punched non woven Geotextile. It has been characterized by high strength, maximum width (6 m) and UV resistant itself with inhibitor. It is resistant to commonly encountered soil chemicals, mildew and insects, and is non biodegradable.

Production process :

The production process of polypropylene non-woven geotextile mainly includes the following steps:

‌Opening‌:

loosen the polypropylene short fiber raw material to make it a loose fiber state.

‌Combing‌:

comb the opened fibers to make the fibers more neat and straight, and remove impurities and short fibers.

‌Web laying‌:

evenly lay the combed fibers into a fiber net of a certain thickness and width.

‌Needling‌:

repeatedly needle-punch the fiber net with a barb needle to make the fibers entangled and embraced

with each other to form a non-woven geotextile with certain strength and stability.

‌Consolidation and shaping‌:

hot pressing or chemical treatment of the geotextile after needle punching to further improve the

dimensional stability and mechanical properties of the geotextile‌

GEOTEXTILE INST ALLATION

To pave by roll with artifical method, the fabric must be level and appropriately leave the margins for

deformation. The inst lation method usually has overlapping, sewing and welding.

The overlapping part is generally more than 0.2m.

It should be welded or stitched for the exposed geotextiles.

AII sewing must be continuously carried out(for example, point-sewing is not allowed),

the geotextiles must be overlapped more than 200mm before overlapping.

The minimum distance between sewing needle and the fabric edge(the edge of exposed material) is at least 25mm.
