specific Embodiment approach 1

[0033] Combine below Figure 1-9 To illustrate this embodiment, a method for preparing a hydrophobic melt-blown cloth comprises the following steps:

[0034] Step 1, stock solution addition: add raw material solution, and the raw material solution is sprayed out;

[0035] Step 2, drafting: high-temperature airflow drafts the raw material solution to form ultrafine fibers;

[0036] Step 3. Cooling: the ejected ultrafine fibers are bonded under the action of self-bonding, and the cooling airflow makes the ejected ultrafine fibers form a melt-blown cloth;

[0037] Step 4, transportation: the melt blown cloth is transported to the next station;

[0038] Step 5. Adjust the angle: adjust the angle of the high-temperature airflow to obtain a melt-blown cloth with good fiber shape;

[0039] The method for preparing hydrophobic melt-blown cloth also relates to a preparation device for hydrophobic melt-blown cloth;

[0040]The hydrophobic melt-blown cloth preparation device includes...

Abstract

The invention relates to a technical field of melt-blown fabric production, and more specifically, discloses a hydrophobic melt-blown fabric preparation method. The hydrophobic melt-blown fabric preparation method comprises the following steps: step 1, stock solution adding: adding raw material solution, and spraying out the raw material solution; step 2, drafting: drafting the raw material solution with high temperature to form a superfine fiber; step 3, cooling: adhering the superfine fiber sprayed out through own adhesive action, making the superfine fiber sprayed out form a melt-blown fabric through a cooling air flow; step 4, transporting: transporting the melt-blown fabric to next work station; step 5, angle adjustment: adjusting angle of the high temperature air flow, and obtainingthe melt-blown fabric with good fiber morphology. In the hydrophobic melt-blown fabric preparation method above, a hydrophobic melt-blown fabric preparation apparatus is also related; the hydrophobicmelt-blown fabric preparation apparatus comprises a melt-blown die head component, an extrusion discharging apparatus, a high temperature air flow generator component, an angle adjustment apparatus, acooling air flow generator and a receiving apparatus, wherein the belt-blown die head component is arranged on the receiving apparatus.

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 ...
