Air humidification for yarns and fabrics
Very sensitive materials react quickly to dry or excessively humid air. Fibres become brittle, textile fabrics contract or expand. This leads to considerable loss of quality already during production.
In addition, the static charge also damages the further processing of yarns and fabrics, in that charged fibres strive apart, are difficult to card or comb and stick to the guide eyelets.
