Abstract

The invention relates to the technical field of melt-blown cloth production, in particular to a preparation method of a hydrophobic melt-blown cloth. A method for preparing a hydrophobic melt-blown cloth, comprising the following steps: step 1, adding a stock solution: adding a raw material solution, and spraying the raw material solution; step 2, drawing: high-temperature airflow draws the raw material solution to form ultrafine fibers; step 3, Cooling: The sprayed ultra-fine fibers are bonded under the action of self-bonding, and the cooling airflow makes the sprayed ultra-fine fibers form a melt-blown cloth; Step 4, transportation: The melt-blown cloth is transported to the next station; Step 5 , Adjust the angle: adjust the angle of the high-temperature airflow to obtain a melt-blown cloth with good fiber shape; the above-mentioned hydrophobic melt-blown cloth preparation method also involves a hydrophobic melt-blown cloth preparation device; The hydrophobic melt-blown cloth preparation device includes a melt-blown mold The head assembly, the extrusion discharging device, the high temperature air flow generator assembly, the angle adjustment device, the cooling air flow generator and the receiving device, and the melt blowing die head assembly is arranged on the receiving device.

Description

technical field [0001] The invention relates to the technical field of melt-blown cloth production, more specifically, a method for preparing hydrophobic melt-blown cloth. Background technique [0002] The patent number is CN201410524317.5, a method for preparing fluffy melt-blown cloth, the invention relates to a method for preparing fluffy melt-blown cloth; raw materials are heated, melted and extruded through a screw extruder, filtered through a filter, and then transported through a pipeline The melt is measured by the metering pump, and then sent to the die head, and fine fibers are formed under the drafting action of high-speed hot air. Under the action of negative pressure, the fiber is laid on the web forming table to form a non-woven fabric; it solves the problems of hard hand feeling of the cloth surface, poor fluffy performance of the fiber, and thin cloth surface thickness; it is fluffy, tough and soft to the touch. But this device can't change the jet angle of ...
