Xavan® / Plantex® Weed Control Fabric

Xavan® is a four-layer span-bond nonwoven polypropylene fabric originally developed by DuPont™ in the United States. The durability is enough with the use of thick fiber.
With excellent water permeability and weather resistance, this weed control fabric smoothly lets rain (water) and liquid fertilizers through and thus can be used for various applications.

High weed control effect

Since thick fibers are fused together, the durability and dimensional stability are extremely high. This fabric controls the growth of Poaceae plants, such as plants with strong penetration force, such as the field horsetail, Congo grass, and reeds.

Water draining effect

The thin structure reduces clogging and effectively lets water permeate through the fabric. The fabric does not affect the soil condition as it provides good water draining effect and air permeability. This fabric also functions as a filter for underdrains in areas with poor water drainage.

Effect of preventing the subsidence of gravel

Gravel gradually subsides through snow accumulation, snowmelt, needle ice, and being walked on. The installation of this fabric prevents such subsidence and eliminates the need to refill the gravel. Since Xavan® weed control fabric has high durability and elasticity, this fabric prevents the subsidence of gravel, deformation of the base ground, and ruts that usually occur over a long period.

High durability

With the special production method of DuPont, Xavan® can remain in good condition for a long period even when it is constantly exposed to UV rays, and its effects are semi-permanent if it is installed in the shade without exposure to UV rays, such as underneath gravel. In addition, hydrolysis would not occur because Xavan® is entirely made of polypropylene.

Easy installation

Environmentally friendly material

Xavan® has been employed for many applications, including uses by the government sector.
