Additional Technical Information:
Two wet spinning pilots for cellulose based textile fibres. 1) Large pilot plant with capacity of 50-100 kg staple fibre per day. Equipped with dissolving, filtration, fibre spinning, staple fibre cutter, washing and post treatment unit, and dryers. Mainy for cellulose carbamate, not for viscose spinning. 2) A smaller semi-pilot scale fibre spinning line (1-5 kg/day) with dissolving and filtration units. The smaller line has possibility for carbamate, alkali dissolved cellulose and viscose spinning.
Both pilot lines are supported by versatile analytics for the solution and fibre charcterisation. Supported by chemical laboratories and pilots for cellulose modifícation, such as celluose pre-treatmets, carbamation or viscose synthesis.
