Geotextile Filter Fabric
Our company is a professional manufacturer/supplier of synthetic filter fabric in construction, made by polymers such as polyester(PET) and polypropylene(PP).Our filter fabric can be classified into two types: one is nonwoven needle punching filter fabric and the other is plastic woven monofilament filter fabric.
Filter Fabric Introduction
"Filter fabric" is a generic term used to describe geotextiles, the primary function of which is allowing water to pass while keeping soil fines from migrating through the fabric. Our company offers a complete line of geotextile filter fabric.

PP Filter Fabric
PP Monofilament Filter Fabric
There are two types of geotextile filter fabrics: needle punched nonwoven and woven monofilament. The most commonly used are needle punched nonwovens. These popular fabrics are used in applications such as wrapping a perforated pipe or the gravel in French drain. A typical silt fence consists of a piece of synthetic filter fabric (also called a geotextile) stretched between a series of wooden or metal fence stakes along a horizontal contour level. There are also nonwovens robust enough for heavy duty filtration applications such as placement under rip-rap for shoreline erosion control. The nonwoven filter fabrics are more robust in handling as compared to their woven counterparts, and therefore were often preferred in large-scale erosion protection projects.
In cases where fine grain sands (beach sands) are present, a woven monofilament is required. Monofilaments prevent the clogging that can occur when fine particles migrate into the matrix of a needle punched nonwoven and get stuck.
Nonwoven Filter Fabric
• Popular
• High Water Flow
• High strength and elongation
Woven Monofilament Filter Fabric
• Percent open area
• Resist clogging
• Very high strengths
In some cases, filter fabric is used wrongly to describe woven separation and stabilization geotextiles. While these products do allow water to pass, they can clog and do not have the flow rates and permittivity of true filter fabrics. In this case, ordinary woven geotextiles cannot be called filter fabric.
We supply 6 oz/8 oz, 140n, 160n, class c/d and another specific non-woven filter fabric. Where to buy filter fabric construction, we Yingfan brand is your good choice.
Applications
Filter fabric can be used in a lot of constructions such as for foundation drainage, silt fence, French drain, driveway, under concrete or pavers, in road construction, and so forth.
Our company have been ISO9001, ISO14001, OHSAS18001 certified. We are always dedicated to supply good quality and cost products to our products.
