Manufacture of fiber and solvent-spun cellulose detection means used in the quality control thereof.

摘要

USED ​​detector elements in a method for the manufacture CONTINUOUS FILAMENT spun cellulose solvents for the presence of "WASTE" OR OTHER MATERIAL UNWANTED IN FILAMENTOS. Accordingly, it presents a method for producing a tow of continuous filaments spun cellulose DISOLVENTES which states: I) the cellulose is dissolved in a solvent amine oxide to obtain a solution PULP HOT, II) THE SOLUTION PULP hot extruded through a die assembly for forming a tow filaments and III) is passed BAST THROUGH a water bath to leach out the amine oxide, wherein the improvement comprises: IV ) DO HAPPEN TO BAST Continuous Filament THROUGH detector elements, V) sensing elements comprise MAKE extends through BAST AND HAVE AN ELEMENT OF RECEIVING IN THE OPPOSITE SIDE OF BAST, WHERE the housing element is calibrated so that it generates a signal if the obscuration BEAM BY VARIOUS ESTOPA in an amount greater than a predetermined. Also it disclosed an apparatus including the sensing elements.
