What is industrial felt and how is it produced?

Industrial felt is one of the oldest fabrics that humans have used for various purposes. Felt is a non-woven fabric that has a very high density, while today fabrics are “woven”.
That is, they are produced with the help of various machines such as knitting and spinning machines. One of the types of felts that are offered in the market is industrial felt, which has wide applications due to its very special properties.

How is industrial felt produced?

In the past, felts were made by hand, but industrial felt is produced by advanced machines and equipment.
When different combinations of different and high quality wools are pressed into nylon and polyester fibers, the result is a very dense product called industrial felt.
Weaving method is not used to prepare industrial felt, but the following operations are performed in the manufacturing process of this product:

to heat
Create moisture

Types of industrial felts

Industrial felt is produced in two types, each of which has its own application and characteristics, and in order to use it, one must pay attention to its type. These two types include compact and semi-compressed industrial felt. The shape of these felts is in two types of round and laminated. Industrial felts are also divided into different types such as refractory felt and filter felt according to their type of application.

Properties of industrial felts

The features of these products are very significant and have made them suitable for use in a variety of industries and factories. These features are as follows:

  • High energy absorption capability (used as sound insulation)
    Prevent the entry and exit of thermal energy (thermal insulation)
    High resistance to the effects of chemicals, water or oil
    Ability to absorb and transfer various fluids
    Very good response to oxidation
    High flash point, which is more than 500 degrees Celsius.
    Ability to be in special environments (non-polar solvents or ultraviolet rays)
    One of its good features is the replacement of damaged parts. In this way, if a part of the felt is removed, it can be easily replaced with another similar piece without any problem.
    Ability to filter suspended liquids in gases
    High flexibility and return to original size after compression
    Use to transmit sound at desired speed
    Insulation against sound transmissions and noise
    High resistance to factors such as abrasion and tension
    Very high durability

Types of industrial felt applications

This product is used to make various industrial parts.
Such as the types of components used for air filtration, thermal insulation, sound insulation, oil absorption, various gaskets, dusters and shock absorbers. One of the industries in which industrial felt is very important is the automotive industry. Other applications of industrial felt include the following:

Application in automotive industry as thermal, acoustic and anti-vibration insulation
Used in the manufacture of filters to prevent the entry of pollutant particles such as dust
Application in machine industry such as lubrication and sealing machines for the production of gaskets or gaskets
Application in insulation for sound insulation, thermal insulation and water absorber
Application in various industries such as automotive, petrochemical, paper, refueling tanks and power plants
Used as sound insulation and reducing the transmission of sound and noise
Ability to filter air and dust in factories such as spring factory, flour factory and cement factory
To prepare parts such as felt bowls, polishing felt and sandpaper
