stitch bonded nonwoven Manufacturers

PP Non Woven Needle-Punched Sludge Filter is your good choice.Needle-punched non-woven fabrics are a kind of non-woven fabrics, which are made of polyester, polyester, and polypropylene raw materials, and are processed through multiple needle punching and proper hot pressing.

Stitch bonded fabrics are composed of directional or random fibers and are a new generation of environmentally friendly materials. It is called cloth because of its appearance and certain properties. A web structure is formed and then reinforced by mechanical, thermal bonding or chemical methods.

Geotextile is a protective layer of composite geomembrane to protect the impermeable layer from damage.

The composite geomembrane has high flexibility, and has excellent chemical and physical properties. These functions will help materials overcome various difficulties in different production areas and provide more feasible suggestions for industrial projects.

Repairs should be postponed to areas at least 30 cm outside the size of the damaged composite geomembrane.

The purpose of geomembrane is to use its anti-permeability effect. Geomembrane should be impermeable to the molecular structure and manufacturing process. However, due to the unevenness and defects in manufacturing, the commonly used geomembrane must not leak. It's just that it is relatively difficult to permeate and what is more important is whether the geomembrane can maintain its anti-seepage performance under the action of long-term water head when it contacts the actual soil (or other materials). Due to the uneven contact surface, rough soil particles, large local deformation of the soil, etc., the geomembrane may be broken or torn under the action of high water head, and its anti-seepage performance will be lost or weakened. Therefore, corresponding anti-seepage tests are also required.
