Document Type and Number:
Japanese Patent JPH06507936
Kind Code:
A
Abstract:
To give a cellulose marked body, a cellulose soln. is shaped while hot in a tert. amine oxide and the shaped soln. is fed to a pptn. bath. Before the hot and shaped soln. is passed to the bath, it is cooled directly after shaping. An appts. has a feed for cooling gas directly below the openings of a spinnerette to cool the cellulose filaments. A gas stream (6) is used to cool the warm material, at right angles to it, or the film formation is at right angles to the gas stream. Two gas streams (6) are used for cooling, from opposite sides of the warm material. In another form, one gas stream can be directed radially inwards at the material and the other stream radially outwards. For the cooling action, heat is extracted from the material at least at 20 kj/kg of soln. and pref. 20-350 kj/kg of soln.
