What Are Nonwoven Filters, and How Are They Are Applied in Construction Industries?

In the manufacturing industry, filtration is a crucial process to get rid of unwanted contaminants in the air, sound, liquids, and so on. You carry out the process of filtration by using a filter. Textile materials play a key role in producing industrial filters. The most commonly used textile materials are woven, knitted, and nonwoven fabrics. The most widely adopted method of making a nonwoven filter is needle punching. However, you can design these filters by any chosen approach - thermal, chemical, and mechanical, depending on your desired function.


Filtration is widely used in different industries like including the automotive industry and construction industry. Air and liquid filtration need filters. Some construction filters can be made by laminating nonwovens.

So, what is the essence of laminating?

Lamination gives them the ability to filter out contaminants of various sizes, depending on the type of filter used. For example, a coffee filter only has to filter out the coffee grounds and permit the passage of water. But, an air filter should filter out the smallest particles of dust and some other contaminants to make sure that it is pure. Coffee filters, water filters, air and aquarium filters, vacuum cleaner filters, oil filters, and others, are all products of nonwoven lamination.

Lamination is useful in manufacturing filters in multiple layers using a nonwoven product. This process combines the physical and mechanical properties of each layer to make a more resilient filter. You can laminate nonwoven filters with other components - like foil, knit, and so on, mechanically by needle punching or thermally by thermal bonding (or heat bonding/melt bonding).

How Are Filters Applied in Construction Industries?

Nonwovens filters are highly essential parts of the homes and buildings undergoing construction, and they bring many benefits to the construction market.

Around 2016, the fastest growth of nonwoven filter was noticed in the construction markets, which made up about twenty-nine percent of nonwovens sales.

Roof insulation

The metal construction industry solely depends on filters that are formed by laminating nonwoven materials. The metal construction industry uses these filters in roof insulation to solve the issue of condensation on uninsulated metal roofing economically. Also, with the help of filters, they can use a self-adhesive acoustic absorber on the roof. This absorber helps to minimize rainfall noise and noise due to some indoor activities.

Furthermore, the metal construction industry uses adhesive tapes that are made from non-wove filters for cable insulation and other specific purposes. These tapes shield materials from acoustic and thermal disturbances. It also regulates their burning behavior.
