TH17572EX - Extruded cellulose fiber production using solvents and quality control equipment. - Google Patents

Abstract

A detection device is provided in a method for making long strands of solvent extruded cellulose to detect "waste" or other unwanted materials on long fibers. Provide a method for doing The fiber clusters of a continuous filament of cellulose extruded using a solvent in which i) the cellulose was dissolved in amine oxide solvent to Hot cellulose solution was obtained. Ii) The hot cellulose solution was extruded through the parent assembly. And iii) the fibers are moved through a water bath for Removes amine oxides where enhancement includes iv) moving the fibers of long fibers. V) A detector consists of a beam of light projected through a group of fibers. And there is a receiving device on the opposite side of the fiber bundle by the device The light receiver has been calibrated to give it a start. The signal when blocking the beam by the fiber group changes too much. Preset volume A machine with a detection device is also provided.

Claims (1)

1. A machine for producing cellulose short fibers from extruded solvent. Which includes equipment for mixing Cellulose and solvent for forming cellulose solutions are heated up, equipment for long multi-fiber clusters. (multi-filament tow) of continuous strands made up of hot dissolving agent, a water bath for washing solvent from the fiber group. Device for moving the fibers of the long fibers through the bath, cutting device at the end of the cutting bath. The fibers of the long fibers are washed into short fibers.
