Hyaluronate nonwoven fabric and manufacturing method therefor

A method for manufacturing a hyaluronate nonwoven fabric, the method comprising the steps of:

• preparing a spinning solution by dissolving hyaluronate with a molecular weight of 50,000 to 100,000 Da at a concentration of 15 to 35%;
• defoaming the spinning solution in a storage tank maintained at 80 to 100° C. to improve the fluidity of the spinning solution;
• forming a hyaluronate fiber bundle by discharging a fixed amount of the spinning solution as a coagulating solution through a nozzle by using a gear pump;
• passing the coagulated hyaluronate fiber bundle through an alcohol tank to clean impurities;
• passing the hyaluronate fiber bundle through an emulsion bath containing glycerin, followed by passing through a heater at 100 to 150° C. for drying and winding on a winder to improve the coherence between the fibers within the fiber bundle;
• cutting the hyaluronate fiber bundle into 1 to 5 mm by using a cutting machine;
• beating the cut hyaluronate fiber in a dissolution tank containing a mixture of alcohol and water at a concentration of 0.1 to 0.5%;
• injecting the beaten hyaluronate fiber-containing solution into a papermaking machine, followed by extracting solution to prepare a sheet shape;
• and
• compressing the sheet shape hyaluronate fiber at 100 to 120° C., followed by fusing and drying to prepare a wet-laid nonwoven fabric.
