First, pour the slices into the chute, then into the hopper, and finally slice into the screw extruder. The sleeve of the extruder is heated in sections, the slices are extruded and melted in the extruder, then enter the continuous pre-filter, and then enter the spinning box. The melt enters the spinning head through a metering pump, and the melt is quantitatively fed into the spinneret by means of accurate metering pump, and is sprayed out through the spinneret hole to form a continuous stream of melt, ie, primary fiber. The primary fibers are then absorbed by monomers, cooled by cold air and drawn by air, and finally formed into filaments. The filament bundle is reciprocated by the cycloid roller and the suction of the positive and negative pressure airflow is evenly laid on the net curtain to form a fiber web. Sticky non-woven fabric . In spunbond production, the stretching and web forming processes are the core of spunbond nonwoven technology, which can reflect the level of spunbond technology. Air drafting is a distinguishing feature of spunbond nonwoven technology that differs from chemical fibers. In the draw shaft of the spunbond equipment, because the airflow speed is much greater than the speed of the wire extruded from the spinneret, the frictional resistance of the wire to the airflow is the main force acting on the wire Under the action of friction, it accelerates and reaches the maximum speed at the slit, so the stretching of the thread is completed between the spinneret and the slit, and the thread is completed under the action of the airflow. Stretch into fiber. "Puzzle 3D Eraser Bulk,Puzzle 3D Eraser,Building Blocks Eraser,Toppers Cute Erasers " Yiwu Shengshang Stationery Co., Ltd. , https://www.ss-stationery.com
