METHOD OF MAKING CELLULOSE FIBRE Russian patent published in 2009 - IPC D01F2/02 D01F2/00 

FIELD: textile; paper.

SUBSTANCE: invention relates to the technology of making cellulose fibre and can be used in the textile industry for making clothes, as well as making reinforcement materials for rubber objects, such as tyres and belts. A cellulose solution is prepared, which is homogeneous at low temperatures, by dissolving a small amount of cellulose powder in concentrated liquid N-methylmorpholine-N-oxide so as to lower solidification temperature. A low-temperature concentrated liquid solution with cellulose and cellulose powder dissolved in it is fed into a kneading machine, mixed until cellulose swells in the kneading machine without reducing pressure obtaining a paste. The paste is fed into an extrusion machine for dissolving so as to obtain a homogenised solution. The solution is extruded through an extrusion nozzle and an air layer in a solidification tank to form a thread. The thread is then washed, dried and treated with oil and wound.

EFFECT: obtaining cellulose fibre.
