This BREF addresses installations for the pretreatment (operations such as washing, bleaching, mercerisation) or dyeing of fibres or textiles. Particular attention is given to the following processes:
• fibre preparation
Upstream processes which may have a significant influence on the environmental impact of the subsequent wet processing activities are also briefly described. The backing of carpets is also included.
All main textile fibre types, namely natural fibres, man-made fibres derived from natural polymers such as viscose and cellulose acetate as well as man-made fibres derived from synthetic polymers are described, including their blends.
