METHOD AND DEVICE FOR CLEANING SPINNERETS WHILE PRODUCING CELLULOSE SPUNBONDED NONWOVEN FABRIC

The invention relates to a method for cleaning a spunbond spinneret for producing a cellulose spunbonded nonwoven fabric from a solution of cellulose in an aqueous organic solvent by extruding the solution through spinneret holes of the spunbond spinnerets in order to form filaments and stretching the filaments in the extrusion direction using a gas flow, wherein impurities containing cellulose accumulate on the spinnerets surface during the method. The method according to the invention has the steps of a) spraying the impurities with a water-containing fluid which precipitates the cellulose; and b) releasing and transporting the impurities away using the gas flow. 本发明涉及一种用于借助于气流对非织造织物喷嘴进行清洗的方法，所述非织造织物喷嘴用于由在含水分的有机溶剂中的纤维素的溶液借助于通过所述非织造织物喷嘴的喷嘴孔挤压所述溶液以形成长丝并且沿挤压方向拉伸所述长丝来制造纤维素非织造织物，在所述方法中，在喷嘴表面处积存包含纤维素的污染物。根据本发明的方法包括下述步骤：a）借助于析出纤维素的、含水的流体对污染物进行喷射；b）借助于所述气流剥离并且运走污染物。
