Abstract
The invention relates to the field of masks, in particular to a preparation method of a melt-blown non-woven fabric. The preparation method comprises the following steps of step 1, heating a polypropylene slice into a molten state and then extruding to reach a nozzle, then spraying through the nozzle, spraying to a net coagulating device, arranging an annular blowing opening with a notch in the circumferential side of the nozzle, and forming an air curtain with a notch around the nozzle by the annular blowing opening; step 2, arranging a short fiber spinneret device between the nozzle and thenet coagulating device and at the gap of the air curtain, and enabling non-coagulated polypropylene fiber to be subjected to superposed spinneret by the short fiber spinneret device; and step 3, setting an arc-shaped air blowing port below the short fiber spinneret device and used for realizing the closing of the air curtain with the notch, thereby achieving guiding of the composite wire, and arranging a horizontal shielding air blowing port above the short fiber spinneret device, so that the air flow is blown to the gap of the air curtain from the outside. The technical problem in the prior art that poor effect is generated when the short fibers are added to hot melt fibers is solved.
Description
technical field [0001] The invention relates to the field of masks, in particular to a method for preparing a meltblown nonwoven fabric. Background technique [0002] At present, the processing of melt-blown non-woven fabrics usually uses a melt-extrusion mechanism for spinning, and then forms on a condensation mechanism, which is often made of polypropylene material. The processing equipment of existing melt-blown non-woven fabric can refer to a kind of melt-blown non-woven fabric processing machine disclosed in CN200810020638.6, which belongs to the technical field of non-woven machinery, and it includes a first frame; A melting extrusion mechanism that is used to process plastic particles into hot-melt fibers at the rear end of the first frame in a state; one is used to guide short fibers to the front of the spinneret of the melting extrusion mechanism and force Short fibers and the hot-melt fibers ejected from the spinneret merge to form a short fiber conveying mechanis...
