The present invention relates to an antibacterial non-woven fabric dressing which comprises: a first cover member including a plurality of pores and brought into contact with a wound; an antibacterial membrane laminated on the first cover member, including a plurality of pores, and formed by the accumulation of nanofibers containing water-soluble polymers dissolving in exudate secreted from the wound, synthetic polymers, and antibacterial substances released by means of dissolution of the water-soluble polymers; and a second cover member laminated on the antibacterial membrane, including a plurality of pores, and exposed to the air. The antibacterial membrane includes: a support member; a first membrane member disposed close to the wound, and formed on one surface of the support member by the accumulation of nanofibers containing water-soluble polymers, synthetic polymers, and antibacterial substances; and a second membrane member preventing the exudate secreted from the wound from passing through while enabling only the external air to pass through, and formed on the other surface of the support member by the accumulation of nanofibers containing synthetic polymers. The first membrane member is formed in a multi-layered structure and each layer is formed by the accumulation of nanofibers containing water-soluble polymers, synthetic polymers, and antibacterial substances. The amount of the water-soluble polymers increases as the layer is getting closer to the wound. 본 발명은 다수의 기공이 형성되고, 상처에 접촉되는 제1커버부재;상기 제1커버부재에 합지되어 있고, 다수의 기공이 형성되어 있고 상기 상처에서 분비되는 삼출물에 용해되는 수용성 고분자, 합성 고분자 및 상기 수용성 고분자의 용해로 릴리즈(release)되는 항균 물질을 함유하는 나노섬유가 축적되어 만들어진 항균 멤브레인; 및 상기 항균 멤브레인에 합지되어 있고, 다수의 기공이 형성되어 있으며, 외기에 노출되는 제2커버부재; 를 포함하고,상기 항균 멤브레인은, 지지부재; 상기 지지부재의 일면에 수용성 고분자, 합성 고분자, 항균 물질이 함유된 나노섬유가 축적되어 만들어진 것으로, 상기 상처에 근접하여 배치되는 제1멤브레인 부재; 및 상기 지지부재의 타면에 합성 고분자로 이루어진 나노섬유가 축적되어 만들어진 것으로, 상기 상처에서 분비되는 삼출물은 통과하지 않고 외부 공기만 통과할 수 있도록 하는 제2멤브레인 부재로 구성되고,상기 제1멤브레인 부재는 다층 구조로 형성되고 각각의 층이 수용성 고분자, 합성 고분자, 항균 물질이 함유된 나노섬유가 축적되어 만들어진 것이며, 상기 상처에 근접하는 층일수록 수용성 고분자의 함량이 많아지도록 한것을 특징으로 하는 항균 부직포 드레싱에 관한 것이다.
