TH57374B - Methods and equipment for producing long fibers - Google Patents

Abstract

The method of making spunbonded textiles from long fibers of the polymer textiles has been commonly disclosed. Bonds are made by extruding polymers in a molten form from holes in the fiber-forming plate to produce long fibers. Filament builder sheet, cooling air flow transverse with long fibers, when long fibers have been pulled out of flow from the fiber generator Long fiber accumulation When long fibers emerge From the pulling device on the conveyor to form Shaped as a mat of long fibers. And making practice work On the mat to join together the long fibers In the fabrication method, long fibers were pulled at speeds greater than 400 meters per minute from the body. Building long fibers A hole in the fiber builder has a close cross-section of a C-shape to approximate the cross-section of the extruded long fibers, have a C-shape and a vented airflow. Heat brought to the C-shaped opening of the long fiber cross section.
