Nonwoven filtration fabrics are one of the largest market segments in the nonwovens industry. This segment uses mainly man-made polymer and inorganic fibers to produce the filters. Polyester and polypropylene dominate; with nylon, fiberglass, meta-aramids and other polymers also used because of their special properties. Fibers are used in increasing volumes where disposable filters are found such as spunbond and meltblown fabrics in vacuum cleaner bags as well as a broad range of performance applications, including coffee and teabag filters. Procotex offers a wide range of sustainable fibres which can be applied for filter applications.
Fibres
- Aramid: Heat resistant non-woven applications
The para-aramid and meta-aramid fibres are very heat resistant. They find application in heat resistant air filters. Generally they are used for applications up to 180°C. Procotex Corporation, and its daughter company Apply Carbon (FR), is a leading manufacturer of sustainable para-aramid fibres for the filter industry
