Non Woven Geotextiles
Yuan Da manufactures a range of non woven fabrics from 17g/m2 to 1500g/m2 with a variation of +/- 5%. Yuan Da's range of non woven fabrics includes: needle punched staple fibre geotextiles; continuous filament spunbonded geotextiles; and thermal embossed fabrics suitable for reusable carry bags. These fabrics can be laser bonded or laminated with a PE film, as required.
The geotexiles are available in 4 or 6 metre wide rolls wrapped in plastic with either cardboard or PVC cores.
The company's modern equipment, ISO9001 accreditation, continuous development and investment programme delivers textiles manufactured to the highest international standards. Each batch laboratory tested and certified.
Yuan Da's textile engineers can also help you design and manufacture a non woven fabric for your industrial or commercial application such as: healthcare and hygiene, cleaning, filtration, food packaging, home furnishings, agribusiness, environment protection and promotions.
Continuous filament, non woven, needle punched, geotextiles
Produced on Italian looms using all new materials Yuan Da's non woven needle punched continuous filament polyester and polypropylene geotextiles are manufactured from the extrusion of fibres which are then laid down on a manufacturing "bed" and then needle punched from both top and bottom to entangle the fibres to produce a dimensionally stable geotextile. Heat bonding can be applied to further strengthen the geotextile.

Staple fibre, needle-punched geotextiles
Our polyester and polypropylene staple fibre geotextiles are needle punched from the top/bottom/top and heat bonded to increase their strength. They are an economical alternative for protecting geomembrane liners against perforation and abrasion. The abrasion resistance of staple fibre, non woven geotextiles is particularly beneficial when only gravel fills are available.
Staple fibre geotextiles are particularly suited for drainage applications. They provide high through flow rates and excellent drainage performance while preventing fines migration. Their high elongation properties limit installation damage which ensures long term performance.
Paving Fabrics
Yuan Da's polyester, non woven, continuous filament, fibre-fired paving fabrics significantly reduce reflective cracking when used in pavements on concrete roads, for repairing existing road surfaces and for the construction of new roads. When saturated with bitumen these geotextiles provide stress relief, waterproofing and reduce reflective cracking in new and existing paved roads.

Advantages :
- Manufactured to ISO9001 standards using new polyester spun bonded continuous fibres, mechanically bonded by needle punching and fibre-fired.
- High melt temperatures. These pavement fabrics do not melt at temperatures below 250oC.
- The fibre-firing process enhances the stability of the fabric when hot bitumens/asphalt are applied. When exposed to hydrocarbons present in bitumen, the fabric is very stable and does not shrink or distort.
- Very strong. Manufactured using from long fibre, needle punched, non woven technology that results in higher tensile strengths for the same weight of fabric. High tear and puncture resistance.
- Minimal surface variation allows the paving fabric to rapidly absorb the applied bitumen and form a tight barrier with the road surface.
- Ease of use. Having one side of the material fibre-fired ensures that the paving fabric will not be lifted by vehicle tyres. Yuan Da's own manufacturing process guarantees the quality of the material when it is laid.
Our paving fabric is supplied in strong UV resistant packaging to prevent deterioration of the product during storage.
