Nonwoven

Nonwoven Fabric

With a shape created by random arrangement of fiber or short fiber, needle punching method is used in case of short fiber. For long fiber, spun-bonding method is used to accumulate about 200~800g/m2 and bonding is done using needle punching or heat fusion.
In general, fibers form random structures with excellent dynamic and mathematical characteristics. Polypropylene and polyester fibers are minly used, and nonwoven fabric performs functions like separation, reinforcement, protection, filter and drainage.

Characteristics and Effects

Light weight allows easy construction.
It shows permanent duration in soil layer and is also durable for deposit in soft ground.
Excellent flexibility and uniformity make it possible to apply this fabric to any structure.
Hydraulic function and filtering are effective for early stabilization of ground.

Use

Scour prevention of swsewage and lakeshore
Stabilization of soft ground and horizontal drainage
Reinforcement of ground for railroad and road constructions, separation between soil layers and absorption of partial impacts
Filtering of fine soil from entering pipes and drainage stones
Leakage prevention in tunnels and drainage function
Protection of waterproof sheet used to prevent leakage of pond and wastes
