Viscose, modal and polynosic fibres Viscose Normal viscose fibres have a low molecular weight. The viscose DP is only 300-400, for example, bleached cotton can have a DP of about 2000. In conventional viscose wet spinning, cellulose regenerates relatively quickly in the spinning bath and the stretch ratio remains low. As a result, the order
