Filtration nonwovens make a mechanical barrier to harmful substances, filter liquids and they clean the air. The filtration process is used in every industry at different stages of the production process.
The most popular are nonwovens for the filtration of liquids. These are mostly spunlace and chemobond nonwovens used as a single layer, as well as filtering systems. Waddings and needle-punched nonwovens are used for air filtration in the pre-filters. Taking into consideration the protection, in the production of respirators spunlace and needle- punched nonwovens are recommended.
