METHOD OF CONTROL OF FIBRE PRODUCTION PROCESS Russian patent published in 1994 - IPC

Abstract RU 2015214 C1

FIELD: production of chemical fibre. SUBSTANCE: the point of invention consists in the fact that in the course of fibre production melt supply to spinning head is controlled depending upon melt pressure in the spinning unit, cooling air supply to the spinning column is controlled depending upon index of blow off condition of fibre thread supplied to receiving device, depth of vacuum in polycondenser is controlled depending upon viscosity of melt at polycondenser outlet. In addition, index of double reflection of formed fibre before receiving device is measured, viscosity of melt being corrected by the value of deviation of measured value of index of double reflection from preset value. EFFECT: enhanced efficiency of production of chemical fibres. 1 dwg
