Abstract (en)
[origin: WO9617118A1] Described is a method of producing shaped cellulose bodies in which a solution of cellulose in a tertiary-amine N-oxide and, optionally, water is warm-shaped and the shaped solution cooled with air before being passed into a coagulation bath. The cooling is carried out using conditioned air with a water content of 0.1 to 7 g of water vapour per kg of dry air and a relative humidity of less than 85 %.
