Textile dust, or textile fibres, is divided into vegetable fibres, animal fibres and inorganic fibres. For our purpose, we use only textile dust. Textile dust arises from the production process of any fabric. The production processes in the textile industry can be divided into two basic groups: mechanical operations (spinning, weaving, knitting) and refining (wet processing, where the main utility properties of the textile are restored). Significant emissions of dust particles also occur in industrial laundries, mainly during the drying process. 

Conventional filter units cannot be used for the filtration or separation of textile dust, as textile fibres tend to clump together and form a blanket when they touch each other. In a conventional filtration unit, the clumps of textile fibres would fill the space between the filter elements and permanently clog the filtration unit. The textile dust is separated by rotary filters, with continuous regeneration of the filter drum by the vacuum system.
