Industry Knowledge

What is filter fabric?
Filter fabric, also known as filtration fabric or filter media, refers to a specialized material designed to remove impurities, particles, or contaminants from fluids (liquids or gases) by allowing the fluid to pass through while retaining the unwanted substances. It is commonly used in various filtration applications across industries.
Filter fabrics are typically constructed using woven or non-woven materials with specific properties that make them effective for filtration purposes. They are engineered to have a porous structure with precise pore sizes and sufficient strength to withstand the filtration process.
The main function of filter fabric is to capture and retain particles or impurities based on their size or other characteristics. As the fluid flows through the fabric, the particles larger than the pore size are trapped, while the fluid or filtered substance passes through.
The pore size of the filter fabric plays a crucial role in determining the filtration efficiency. Smaller pore sizes can capture smaller particles, resulting in finer filtration. The choice of filter fabric depends on the specific application requirements, including the desired filtration level, fluid type, temperature, chemical compatibility, and flow rate.
What is the filtration efficiency of filter fabrics?
The filtration efficiency of filter fabrics refers to the ability of the fabric to capture and retain particles or impurities from a fluid stream. It is a measure of how effectively the filter fabric can perform its filtration function.
Filtration efficiency is typically expressed as a percentage and represents the proportion of particles or impurities that are captured by the filter fabric. The higher the filtration efficiency, the greater the ability of the fabric to remove contaminants from the fluid.
The filtration efficiency of filter fabrics is influenced by several factors, including:
Pore Size: The size of the pores or openings in the filter fabric determines the range of particle sizes that can be effectively captured. Smaller pore sizes can capture smaller particles, resulting in higher filtration efficiency for finer filtration.
Fiber Diameter: The diameter of the fibers used in the filter fabric can impact the filtration efficiency. Finer fibers can create smaller gaps and increase the likelihood of capturing smaller particles.
Fabric Thickness and Density: The thickness and density of the filter fabric can affect the filtration efficiency. Thicker or denser fabrics may provide more filtration surface area and increase the chances of particle capture.
Surface Charge or Electrostatic Properties: Some filter fabrics may have inherent electrostatic properties or be treated with additives to enhance filtration efficiency. These properties can attract and capture charged particles more effectively.
Flow Rate: The flow rate of the fluid passing through the filter fabric can influence filtration efficiency. Higher flow rates may reduce the contact time between particles and the filter fabric, potentially affecting the capture efficiency.
Filter Cake Formation: In some filtration applications, a filter cake can form on the surface of the filter fabric as particles accumulate. This filter cake can enhance the filtration efficiency by providing an additional layer of particle capture.
