Spining technology for viscose rayon continuous spinning machine

Abstract

The spinning process for viscose rayon continuous spinning machine includes the following steps: making the viscose pass through viscose tube, metering pump, filter, spinneret seat and spinneret and jet from die-spinning nozzle, solidifying in setting bath to obtain thread-line, after formed, spirally window said thread-line along its axis from one end of paired rollers formed from common roller and small diameter roller which have a certain included angle from axis, and winding out from another end, and making it pass through yarn guide and wind around bobbin to form bobbin, then making the three-line undergo the processes of continuous setting, washing unit water, oiling and drying. The described paired rollers are formed from one common roller and at least two small diameter rollers which are respectively two-by-two combined.

Description

Technical field: [0001] The invention relates to a spinning process of a viscose rayon continuous spinning machine. Background technique: [0002] The existing viscose rayon continuous spinning process is as follows: the viscose is sent from the viscose tube to the metering pump-filter-the spinneret seat-the spinneret, and the viscose is ejected from the spinneret hole of the spinneret , solidified into filaments in a coagulation bath, and the filaments are formed in a forming tube filled with a coagulation bath, and the filaments coming out of the forming tube are wound on a common roller and a small-diameter roller with a certain angle between the axes after passing through the acid scraping device On the formed pair of rollers, due to the included angle between the axes of the pair of rollers, the filament is wound from one end of the pair of rollers, spirally wound to the other end of the pair of rollers, and wound out from the other end of the pair of rollers, It is wo...

AI Technical Summary

Problems solved by technology

The disadvantage of this spinning process is that if you want to increase the number of spinning filaments, you must increase the number of small-diameter rollers, which makes the equipment have disadvantages such as large investment, large floor space, low output, and high production costs.
