Filter fabric is a type of textile that is used for filtering liquids and gases. It is made from a variety of materials, including polyester, nylon, and fiberglass. The fabric can be either woven or non-woven.
So, which is better &#; wovenvs non-woven filter fabric? Keep reading to find out!learn more(wikipedia)
Non-woven filter fabric is typically made from synthetic fibers that are tightly packed together using heat, chemicals or mechanical processes. This creates a web-like structure that can trap particles and impurities. Non-woven fabrics are often preferred for their high filtration efficiency, low pressure drop, and resistance to chemicals and abrasion. They are commonly used in applications such as air filtration, oil filtration, and water filtration.
Woven filter fabric, on the other hand, is made by weaving threads or yarns together in a specific pattern. The resulting fabric can have a variety of characteristics based on the type of weave used, the thread count, and the material used. Woven fabrics are often favored for their durability, strength, and ability to withstand high temperatures. They are commonly used in applications such as industrial filtration, where the filter must withstand harsh conditions and high pressures.
In terms of performance, both non-woven and woven filter fabrics have their strengths and weaknesses. Non-woven fabrics are generally more effective at filtering out smaller particles, while woven fabrics are more durable and can withstand higher pressures and temperatures. Ultimately, the choice between non-woven and woven filter fabric will depend on the specific needs of the application.
When choosing a filter fabric, there are other factors to consider besides its filtration efficiency and durability. For example, you may need to consider the cost of the fabric, its availability, and its environmental impact. Non-woven filter fabrics are generally more cost-effective and easier to produce than woven filter fabrics. They are also often made from recycled materials, making them a more environmentally friendly option. Woven filter fabrics, on the other hand, are often more expensive and may be harder to source, but they offer superior performance in harsh conditions.
It is also important to consider the maintenance requirements of the filter fabric. Non-woven filter fabrics can often be disposed of after use, while woven filter fabrics may need to be cleaned and maintained in order to prolong their lifespan. In addition, you may need to consider the compatibility of the filter fabric with other components of your filtration system, such as the filter housing and seals.
Choosing the right filter fabric is a critical decision that can impact the performance and lifespan of your filtration system. Whether you choose a non-woven or woven filter fabric will depend on your specific needs and requirements. By considering factors such as cost, availability, environmental impact, maintenance requirements, and compatibility, you can make an informed decision that will ensure the success of your filtration system.
There are many types of &#;dust collectors&#; and terms used for the dry technologies that collect particulate matter from a gas stream. These terms include: Pulse-Jet Dust Collector System (can be a fabric filter), Reverse Air Baghouse, Cyclone, Cartridge Collector, or Shaker Collectors. However, for this brief we will focus on fabric filters.
Dust laden gases come in contact with filter bags inside a baghouse. Depending on the type of fabric filter, dust comes in contact with the filter bag and either collects on the inside or outside of the bag.

Fabric filter is the technical term for what is commonly known as a baghouse or dust collector. A fabric filter is an air pollution control device that removes particulate matter from a process gas stream before it is emitted into the atmosphere.
There are several types of fabric filters, but they all have a few items in common:
In , Dustex (now known as LDX Solutions) started engineering and designing high efficiency cyclones in response to the food industry&#;s need for product collection. Since then, the design and engineering has evolved, and the market has a variety of collection equipment for a variety of application. Today, the Dustex® branded products include many types of our designed and engineered dust collectors and fabric filters.
For &#;fabric filters&#; or baghouses the main difference in the designs is how the filter bags are cleaned.
With a pulse-jet fabric filter, the bags are supported by metal cages and they hang from a tubesheet located at the top of the fabric filter. The process is such that as the dirty air enters the fabric filter, the dust/particulate matter is collected on the outside of the bags as the air passes from the outside to the inside; building up a dust cake. The now clean air then exits the fabric filter. Pulsing or short bursts of compressed air cleans the bags of the dust buildup at regular intervals; intervals can be determined by system differential pressure or time. Cleaning can be online, meaning this occurs while the fabric filter is still in operation, or offline, meaning the compartment no longer has process air flowing through it during the cleaning cycle.
A reverse air baghouse cleans at a lower pressure than a pulse-jet baghouse. Instead of using compressed air, cleaning air is generated by a low pressure/high volume fan which blows reverse air into the clean air plenum to remove the dust. Reverse air baghouses are typically cleaned offline.
A reverse air fabric filter collects dust on the inside of the bags (as opposed to the outside of the filter bags as seen on pulse jet units). No cages are supporting the bags so as the dust cake cuts off the inflow of dirty air, it uses the reverse flow of clean air to remove the dust. The bags partially collapse and remove the dust.
In the past, the argument for reverse air baghouses in lieu of a pulse-jet baghouse was that the high pressure and compressed air led to higher operating costs with a pulse-jet fabric filter. However, if designed properly for your operation, this cost can be kept in check. Improperly sizing a fan for a reverse air baghouse can be just as costly from an operational expense.
The shaker baghouse bags usually hang from the top of the unit and attach to the tube sheet at the bottom. The cleaning process is mechanically shaking the bags. Generally, the dirty air enters the baghouse from the bottom and is pulled through the inside of the bags, where the dust is collected. The cleaning process is off-line, meaning that the system must be shut off for the shaker to remove the dust.
Note: There is a science to designing a system that meets your operation&#;s process conditions. It is important that you carefully consider an experienced and successful supplier with a long history of operating installations. A properly sized fabric filter and properly prescribed filter media or bags, can provide you with a high efficiency filtration system and long bag life.
Today, fabric filter technology is often prescribed as part of a solution for a plant process that not only has particulate matter in its process but also includes NOx, SOx, Mercury or some other form of gas pollutant.
