[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0015] Example 1

[0016] Combine Figure 1 This embodiment is described in detail. A hot air non-woven fabric containing natural dry flower petals comprises: a non-woven fabric body, wherein the non-woven fabric body comprises a first hot-melt fiber layer 1 and a second hot-melt fiber layer 2; natural dry flower petals 3 are spread between the first hot-melt fiber layer 1 and the second hot-melt fiber layer 2; the natural dry flower petals 3 are fixed between the first hot-melt fiber layer 1 and the second hot-melt fiber layer 2 by hot air bonding; the first hot-melt fiber layer 1 and the second hot-melt fiber layer 2 are both low-melting-point polyester composite fiber layers; plant extracts are sprayed on both sides of the non-woven fabric body.

[0017] Furthermore, the fibers used in the low-melting-point polyester composite fiber layer are low-melting-point polyester composite fibers; these fibers have a core-sheath structure, with the core layer being polyester fibers and the sheath layer being low-melting-point polyester fibers, with the melting point of the low-melting-point polyester fibers being between 130-140°C. Hot air bonding refers to a production method in which hot air is used to penetrate a web on a drying machine, causing it to melt and bond. In this embodiment, the low-melting-point polyester composite fibers are used. The low-melting-point polyester fibers in the sheath layer melt quickly upon heating, creating a bond between the fibers and securing the natural dried petals 3 between the first and second hot-melt fiber layers 1, 2. The hot-air bonded nonwoven fabric body exhibits an effective point-bonding structure, resulting in a fluffy and soft appearance.

[0018] Furthermore, chitosan powder is attached to the surface of the natural dried petals 3. Specifically, the chitosan powder is water-soluble chitosan with a degree of deacetylation of 90%. Its molecules contain active polar groups such as hydroxyl and amino groups, which have high reactivity and have a significant effect on inhibiting the growth and reproduction of microorganisms, especially Escherichia coli and Staphylococcus aureus.

[0019] Furthermore, the natural dried petals 3 are dried rose petals, dried marigold petals, or dried chrysanthemum petals.

[0020] Furthermore, the plant extract is an extract of Qingfengteng from western Hubei, Qingfengteng with gray back, or Qingfengteng with small flowers. Specifically, the plant extract is an extract of Qingfengteng from western Hubei. Qingfengteng from western Hubei, Qingfengteng with gray back, and Qingfengteng with small flowers all belong to the genus Qingfengteng of the family Qingfengceae. The low-polarity components in the plant extracts are mostly concentrated in the petroleum ether extraction site, and the main structural types are mostly long-chain fatty hydrocarbons, monoterpenes, sesquiterpenes, etc., with a wide variety and small structural differences. The monoterpenes, sesquiterpenes, and diterpenes in Qingfengteng from western Hubei have anti-inflammatory effects. The fatty acid component ethyl palmitate in Qingfengteng with small flowers can reduce the release of inflammatory factors tumor necrosis factor α and interleukin 6 in the plasma of rats with lipopolysaccharide-mediated endotoxemia model. D-α-tocopherol and γ-tocopherol in Qingfengteng with gray back may be its main anti-inflammatory components; in addition, the pentacyclic triterpenoid component moretinol in Qingfengteng with gray back has also been shown to have good anti-inflammatory activity. Extracts of Qingfengteng from western Hubei, Qingfengteng from gray back, or Qingfengteng from small flowers all have anti-inflammatory effects.

[0021] Example 2

[0022] Combine Figure 2This embodiment is described in detail. On the basis of the first embodiment, the non-woven fabric body further includes a two-component sheath-core structure polylactic acid fiber layer 4, and the two-component sheath-core structure polylactic acid fiber layer 4 is arranged on the side of the first hot-melt fiber layer 1 away from the natural dry petals 3. The two-component sheath-core structure polylactic acid fiber layer 4 is compounded with the first hot-melt fiber layer 1 by hot air bonding. The sheath layer of the two-component sheath-core structure polylactic acid fiber is PDLLA type polylactic acid with a melting point of 120-130°C, and the core layer is PLLA type polylactic acid with a melting point of 170-180°C. The surface of the PLA fiber contains trace amounts of lactic acid, which has an antibacterial effect and can kill Escherichia coli and Staphylococcus aureus, thereby improving the safety of disposable sanitary products.

[0023] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology should be within the scope of protection defined by the claims.
