Component Supply&#;s stock of filter mesh is a versatile material used in multiple industries and in a variety of applications. To assist researchers and product designers in choosing the best mesh for their applications, we want to define and explain the different properties of our mesh and how they impact each other.

There are seven major attributes of mesh: 1) mesh opening, 2) open area, 3) mesh count, 4) thread diameter, 5) weight, 6) thickness and 7) air permeability. At Component Supply, we don&#;t list weight, thickness or air permeability in our product information because, unlike the first four specifications, these three are not typically relevant in determining mesh use most applications. However, to give you a full picture of mesh properties, we will provide a simple definition for those terms as well.

Mesh Attributes

1)     Mesh Opening refers to the actual size of the opening. In the charts on our site, this is measured in microns. Mesh opening is typically the most critical attribute because it determines the size of the particles it will capture and the size of the particles it allows to pass through. This attribute is specified in microns, which is a metric measurement equaling one thousandth of a millimeter.

2)   Open area indicates the percentage of a specified area that is open. Open area can help determine what sort of flow restrictions might occur because of the filter. If we take a square piece of mesh screening that is exactly one inch by one inch and move all the lateral and horizontal fibers (warp and weft &#; we will cover this in another post or video) up and to one side we will be left with some part of the square that is solid (covered by the threads) and some part that is now open. With a mesh that has a 25% open area the square inch will be segmented into four parts, three (75%) will be covered by the threads and one (25%) will be open.

3)     Mesh count is the number of threads in a linear inch and is fairly easy to determine. For example, if you were to lay out a piece of mesh and place a ruler on top, then count the horizontal threads from the beginning of the ruler to the one inch mark that would give you the mesh count. Of course, this is a simple task for mesh sizes like microns, which has 19 threads per inch. But it is daunting or even flat out impossible for some of the smaller mesh sizes. For mesh sizes down to about 200 microns you can count, or at least count one quarter of an inch and multiply. For sizes much smaller than that, it becomes difficult without some magnifications and a good bit of patience.

4)     Thread diameter is the diameter of the thread measured in microns.

5)     Weight is the weight of the material typically measured in ounces per square inch.

6)     Thickness is the overall thickness of the mesh and measured in microns.

7)     Air permeability measures the rate of air flow passing perpendicularly through the mesh and, for our mesh, is measured liters (l)/square meter (sq. m.)/second (s).

The Relationship between Mesh Attributes

When selecting the appropriate mesh for an application it is important to know how these attributes are related to each other. Let&#;s use an example of mesh that has a 500 micron mesh opening, a 50% open area, a thread count of 20 and a thread diameter of 250 microns. If we were to change just one of these attributes, it would completely alter the product you&#;d be using. For example, if we decreased the thread diameter but left the mesh count constant, we would wind up with a larger mesh opening and open area. If we needed to capture smaller particles with a smaller mesh size, but wanted a similar open area for flow restriction reasons you could find a mesh that has the same thread diameter and a higher mesh count, or you could find a mesh that has an increased thread diameter and keep the thread count constant.

Conclusion

Understanding the attributes of mesh and how they relate, makes selecting it for a specific application less daunting. That being said there are not an infinite number of possibilities available. This mesh is woven on looms that produce as much as 10,000 meters at a time, so only very large filtration and screen printing applications get to &#;choose&#; what they really want in terms of mesh properties. While there may be other sizes, and we encourage you to ask about them, the specifications on our site represent most of what is available. Understanding the properties of mesh and how they are related and then purchasing based on that information is more effective and realistic than trying to customize your own mesh.

Its unique properties make it an ideal choice for applications ranging from water and air filtration to use in the food and beverage industry. This guide delves into the world of polyester filter mesh, exploring its types, applications, benefits, and much more.

What is Polyester Filter Mesh?

Composition and Structure

Polyester filter mesh is made from polyester fibers woven into a mesh structure. This structure can vary in terms of the density of the weave, which determines the mesh size and, consequently, its filtration capabilities.

Key Characteristics

Polyester filter mesh is known for its strength, durability, and resistance to chemicals. It is lightweight yet robust, making it suitable for various filtration tasks.

Types of Polyester Filter Mesh

Monofilament Mesh

Monofilament polyester mesh is made from single strands of polyester. It offers precise filtration and is easy to clean, making it ideal for applications where accuracy and hygiene are paramount.

Multifilament Mesh

Multifilament polyester mesh, on the other hand, is woven from multiple strands of polyester. It provides a greater surface area for filtration but can be more challenging to clean compared to monofilament mesh.

Manufacturing Process

Raw Material Selection

The quality of the raw polyester fibers is crucial. High-grade polyester ensures that the resulting mesh has the desired properties of strength and chemical resistance.

Weaving Techniques

The weaving process involves interlacing the polyester fibers in specific patterns to create the mesh. The technique used can affect the mesh's filtration efficiency and durability.

Finishing Treatments

Post-weaving treatments can enhance the properties of the mesh. These treatments may include heat-setting to stabilize the mesh and surface treatments to improve its chemical resistance.

Applications of Polyester Filter Mesh

Water Filtration

Polyester filter mesh is extensively used in water filtration systems, from household filters to large-scale industrial setups. Its ability to remove impurities efficiently makes it a popular choice.
