Apparatus for making spunbonded fabrics
Abstract
Abstract A PROCESS FOR PRODUCING SPUNBONDED NONWOVENFABRICS IS DISCLOSED, WHEREIN CONTINUOUS FILAMENTS OF ORGANIC POLYMERS ARE EXTRUDED, STRETCHED TO ORIENT SAME, AND THEN ARRANGED IN FABRIC FORM ON A MOVING CONVEYOR. THE FILAMENTS ARE ARRANGED OR DISTRIBUTED ON THE MOVING CONVEYOR BY IMPACT FROM A DEFLECTOR SURFACE, WITH A FLUID JET OPERATING UPON THE POINT OF IMPACT FORM A LOCATION IN FRONT OF THE POINT OF IMPACT IN RELATION TO THE DIRECTION OF THE DEFLECTED FILAMENTS, AND IN THE SAME PLANE AS THE AXIS OF THE FILAMENTS BEFORE AND AFTER IMPACT WITH THE DEFLECTOR SURFACE. THE SUPNBONDED NONWOVEN FABRIC PRODUCED BY THE DISCLOSED PROCESS ARE MORE HOMEGENEOUS THAN PRIOR SPUNBONDED NON-WOVEN FABRICS, AND ARE SUITABLE FOR KNOWN USES OF SUCH BABRICS, SUCH AS APPAREL BACKING PADDING AND THE LIKE.
