Definitions

  • the upper sheet has the largest surface area in contact with the wearer's skin, and when the contact surface with the skin is formed with synthetic materials, the hydrophobic properties of the synthetic materials need to be converted to hydrophilic properties, and the hydrophilic emulsion used in this process is composed of surfactants that are harmful when in contact with the skin.
  • a disposable absorbent product using natural cotton is registered in the Republic of Korea Patent Publication No. 10-0860099 (September 25, 2008).
  • the technical problem of the present disclosure is to provide an absorbent article equipped with a natural cotton mesh, which has excellent wearing comfort (touch) when natural cotton comes into contact with the skin of a wearer or a pet, and has a mesh structure that allows smooth ventilation, thereby preventing the skin of the wearer or pet from being irritated or inflamed by secretions, thereby keeping the skin clean.
  • Another technical problem of the present disclosure is to provide an absorbent article having a natural cotton mesh that can prevent body fluids (urine, menstrual blood, secretions, etc.) of a wearer or a pet from leaking from the absorbent article by means of wing-shaped side gathers formed to face the side.

  • the present disclosure provides an absorbent article equipped with a natural cotton mesh, in one embodiment, comprising: a natural cotton layer formed in a mesh shape to come into contact with the skin of a wearer and allow body fluid (secretion) to pass through; an absorbent layer having upper non-woven fabric and lower non-woven fabric formed on the upper and lower surfaces, in which body fluid passing through the natural cotton layer is absorbed and retained; a liquid-impermeable back sheet for preventing body fluid from leaking out from the absorbent layer; first and second elastic bands formed on the left and right edges to have elasticity when worn by the wearer; and a fixing means for removably fixing the absorbent article to the wearer, wherein the absorbent layer comprises a superabsorbent material.
  • a urine line formed on one side of the underside of the back sheet may be further included.
  • FIG. 1 is a perspective view of an absorbent article equipped with a natural cotton mesh according to one embodiment of the present disclosure.
  • Figure 2 is a schematic cross-sectional view of an absorbent article provided with the natural cotton mesh illustrated in Figure 1.
  • FIG. 4 is an enlarged cross-sectional view of another embodiment of an absorbent article provided with the natural cotton mesh illustrated in FIG. 2.
