Provided are environment-friendly and biodegradable non-woven fabric, and an apparatus and a method for producing same, the method for producing the non-woven fabric according to an embodiment of the present invention comprising: step S10 for producing a first PLA fiber and a second PLA fiber by inserting biodegradable PLA into respective extruders of first and second fiber-producing machines and melting, spinning by means of a spinning nozzle having hundreds of small orifices, and fiberizing by elongating and cooling by means of heated high-pressure air sprayed from both sides of the spinning nozzle at high speeds; step S20 for spraying the first PLA fiber produced from the first fiber-producing machine on a first mesh drum to accumulate into a web, and spraying the second PLA fiber produced from the second fiber-producing machine on a second mesh drum to accumulate into a web; step S30 for supplying and interposing pulp in between the first PLA fiber and second PLA fiber accumulated into webs; and step S40 for combining the first PLA fiber, pulp and second PLA fiber by thermal bonding. According to an embodiment of the present invention, the smoothness, absorbency and volumetric characteristic of the pulp are preserved by interposing pulp having smoothness, absorbency and volumetric characteristic in between the first and second PLA fibers having superb physical characteristics, non-woven fabric having superb product quality can be effectively produced as the first and second PLA layers hold and protect the pulp layer to impart the necessary mechanical strength during actual use, and the production cost can be reduced by means of a simplified process. |
