The difference between non-woven fabric and filter cotton, can we use non-woven fabric instead of filter cotton

Can non-woven fabrics be used instead of filter cotton? On this issue, we first need to understand the process of non-woven fabric and filter cotton.

As the name implies, non-woven fabrics have different production processes from textile fabrics. They are made of fibers through non-woven processes. According to the processes, they can be divided into: Spun laced non-woven fabrics, heat sealed non-woven fabrics, pulp air laid non-woven fabrics, wet non-woven fabrics, spun bond non-woven fabrics, melt blown non-woven fabrics, needle punched non-woven fabrics and hydrophilic non-woven fabrics. The main materials are polypropylene fiber, polyester fiber, nylon fiber, viscose fiber, ethylene fiber and chlorine fiber. For example,thenon-woven PPS filter cloth filter

Non-woven fabrics are widely used in medical, household, clothing, agriculture, industry, packaging, civil engineering and so on.

Each kind of non-woven fabric has its own advantages, so the non-woven fabric used in different occasions is different.

Filter cotton is also a kind of non-woven fabric, so non-woven fabric is a big category, and filter cotton is one of the subdivisions.

The production process of filter cotton is mainly divided into heat sealing and needling. Heat sealing is to fuse fibers of various fineness and hot melt fibers through high temperature heating to form products with fixed thickness and density. Because of its good permeability and filtration effect, it is mainly used for primary filtration in various occasions where clean environment is required. Dust can be blocked on the fibers of air inlet filter cotton. Needling refers to that the fibers of various fineness are laid on the net and then needled to make them closely together. The air permeability ofneedled filter cottonand heat sealing filter cotton with the same thickness is different. The air permeability of needled filter cotton is relatively small, but its advantage is that it can be cleaned more times and the cost is low, so it is also widely used in the production of air filter bags,for example ,theglass filter mediaair filter

No matter which process the filter cotton has its function.

Filter cotton is one of the non-woven fabrics. However, because the non-woven fabrics of different processes have different uses, non-woven fabrics cannot replace filter cotton.

Our company SFFILTECH can produce various thickness of primary effect filter cotton and medium effect filter cotton, which are used for primary effect air filtration in automobile factories, furniture factories, hospitals, schools, various squares, electronic factories, chip factories, spray paint rooms, etc. it is the pre filter device of medium effect filter bags, which can effectively block dust above 5 microns, greatly extend the life of the rear medium and high efficiency filter, and reduce the operating cost.

Medium and low efficiency filter cotton can be cut and packed according to customer’s requirements.
