Importance of Technical Textiles as Filtration Media-A Review

Abstract

Textiles are widely used in our day-to-day needs like filtration of air, liquids, food
preparation as well as industrial production in large to keep us healthier from the
surrounding environment. A variety of fibres, yarns and fabrics both in woven and nonwoven
types are used in the field of filtration techniques. The innovative applications of textile
filtration fabrics is widely accepted in the pharmaceutical industry in the process of
separation of liquids, gases, powders and suspensions involved in the filtration processes.
Textile materials in any form play an important role the industrial filtration. In the present
industrial processes, there is hardly any process is left where filtration is not involved. In the
filtration process, where any textile material used it is called as the filter media or medium.
In general filter media is used either in the solid-gas and/or solid-liquid separation. The use
of latest technologies with filters and filtration media, the effective time in filtration is
reduced and better quality of products are obtained in pharmaceutical industry. The use of
textile filtration materials helps maximum separation of particles from the liquids, although
absolute clarity is not always required. The use of membrane filtration fabrics in water
filtration process has improved the membrane science.
