Acrylic Needle Felt Filter Cloth
Acrylic Needle Felt Filter Cloth is a type of non-woven filter media made from 100% homopolymer acrylic fibers.
Product Details
Acrylic Needle Felt Filter Cloth is a type of filtration media made from acrylic fibers, which are synthetic fibers composed of polymers derived from acrylonitrile. The “needle felt” designation refers to the manufacturing process where the fibers are felted together through the mechanical action of barbed needles. This process creates a dense, non-woven fabric with a high surface area that’s suitable for filtering particulates from gases or liquids.
Key characteristics of Acrylic Needle Felt Filter Cloth include:
- Hydrolysis Resistance: Acrylic fibers are highly resistant to degradation from hydrolysis, making this filter cloth suitable for moist or humid conditions where other materials might break down.
- Chemical Resistance: It has good resistance to acids and alkalis, as well as to most oxidizing agents, which makes it useful in a variety of chemical environments.
- Thermal Stability: Acrylic filter cloth can operate in medium-temperature applications, generally up to about 125°C (257°F).
- Dimensional Stability: The fabric maintains its shape and size during use, which is important for the consistent performance of the filtration system.
- Self-Extinguishing: Acrylic fibers tend to self-extinguish when removed from a flame source, adding a measure of safety in applications with potential fire hazards.
- Ease of Cleaning: The surface properties of the fibers facilitate the release of dust cake during cleaning cycles, maintaining air flow and filtration efficiency.
Acrylic Needle Felt Filter Cloth is frequently used in dust collector systems in industries such as chemical processing, waste management, food and beverage production, and any application where performance in moist or acidic gas streams is required. It is typically fashioned into filter bags or other types of filters used within baghouse dust collectors and similar filtration equipment.

Acrylic Needle Felt Filter Cloth is crafted from homopolymer acrylic fibers and is noted for several features that make it suitable for a variety of industrial filtration applications. Here are some of the prominent features of Acrylic Needle Felt Filter Cloth:
- Hydrolysis Resistance: Acrylic fibers are resistant to hydrolysis, meaning they can withstand exposure to water and steam without deteriorating. This makes the filter cloth well-suited to environments with high humidity or wet processes.
- Chemical Resistance: It offers good resistance to most organic and inorganic acids, as well as to alkaline materials, making it applicable in a range of chemical environments.
- Moderate Temperature Tolerance: Acrylic filter cloth can operate continuously in environments with temperatures up to approximately 125°C (257°F), which is suitable for medium-temperature applications.
- Dimensional Stability: The needle felt maintains its form and size under typical operating conditions, which is essential for the consistent performance of the filter bags made from it.
- Self-Extinguishing: Acrylic fibers have flame-retardant properties, meaning they tend to self-extinguish when the flame source is removed, reducing the risk of fire in the filtration system.
- Good Dust Release: The structure and properties of the fibers allow for effective dust cake release during the cleaning cycles of the dust collector, which is important for maintaining airflow and system efficiency.
- Durability: Acrylic needle felt is known for its durability and ability to withstand wear and tear, which translates to a longer service life for the filter media.
- Antistatic Options: Some acrylic needle felts are available with antistatic treatments or fibers to reduce the risk of static charge build-up, which is important in certain explosive or flammable environments.
- Ease of Fabrication: The material can be easily fabricated into various shapes and sizes, making it versatile for different types of filtration systems, including filter bags and cartridges.
Acrylic Needle Felt Filter Cloth is commonly used in waste incineration, chemical processing, food and beverage manufacturing, pharmaceuticals, and any industry where filtration systems need to perform reliably in the presence of moisture or acidic gases. It is often used in the form of filter bags within baghouse dust collectors.
