What Are the Methods to Produce Non Woven Filter Media?

Filters have been part of our daily routine. The morning coffee is made using a filter to water purified with filters to the filter in the vehicle; this has been an essential component of our day-to-day lives. We require filters to refine the air and water, and our cars and machinery require top-quality filter media for smooth functioning. The industry is shifting towards technological advancement; filter media is still rapidly growing and is estimated to grow to 50 billion USD. This prediction reflects the prosperous future of the filtration industry. 

Lets Us Understand What is a Nonwoven Filter Media

The purpose of filtration is to purify the air and water to be used for safe consumption, industrial use or other utility. Filters are made in different shapes and sizes that serve various purposes. The filters can be of two types which are woven and non-woven. The woven filter comprises intertwined single strands of desired material like monofilament or fibrillated yarn. The nonwoven filters are prepared in a procedure which includes merging the fibre in an order or a random pattern and joining the layers of the unwoven with the help of a polymer. In this way, the filter media is prepared.

Following Are the Methods to Produce a Nonwoven Filter Media.

The filter fabric manufacturer in India uses many methods to produce non-filters that depend on the filtration needed. Shankar Techx is one of the best filter fabric manufacturer that delivers top-quality filter media solutions. Here are a few of the methods used for non woven filtration:

  • The Carding Method

This method of non woven filter is commonly used for the filtration of masks, filtering cooking oil or milk. The carding filter media is a traditional method that involves merging different types of material either by resin or heating.

  • Wet-Laid Filter

Many Agro tech products suppliers use this method to make swimming pools, HEPA, or coffee filters. These filters are made by a process similar to paper making, using a mix of either handmade or natural or fibreglass that is transformed into a paper-like media filter. 

  • Melt-blown Filter Media

This type of filter media is appropriate for the filtration of small particles such as dust, dirt or smoke. These kinds of filters are usually found in respirators, and these filters can be mass-produced. In the melt-blown method, fibres are not used; the polymer is heated and melted to make these filters.

  • Spun-bonded Filter Media

These are super light filter media that can filter and purify water or air. Like the meltdown filter, this filter media is prepared without fibres. Instead, spun nylon or spun polyester makes it super light and heat-resistant.

  • Lamination

The lamination methods include using different techniques to merge different layers of the nonwoven filter media with polymers to transform into a composite, which has the properties of all the used materials. 

The non woven filters offer numerous advantages to the customers and industries that use them. It is used for air, water, automotive, and speciality filtration. Shankar Techx is a leading textile manufacturer that produces a wide range of filtration media and many agro tech products suppliers  to customers and other industries. They export and manufacture filtration fabrics that serve multiple purposes.
