DETAILED DESCRIPTION

[0023] The present invention will now be described more fully below with reference to the accompanying drawings, in which the present invention is shown in its currently preferred embodiments. However, the present invention can be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and these embodiments fully convey the scope of the present invention to the skilled person.

[0024] Example 1: An antibacterial nonwoven fabric, see Figure 1-Figure 3 As shown, it includes a non-woven fabric base layer 1, an antibacterial fiber layer 2, an activated carbon fiber layer 3 and a breathable layer 4. The bottom of the non-woven fabric base layer 1 is paved with an antibacterial fiber layer 2 for antibacterial and antimicrobial purposes, the bottom of the antibacterial fiber layer 2 is paved with an activated carbon fiber layer 3 for absorbing impurities and moisture, the bottom of the activated carbon fiber layer 3 is paved with a breathable layer 4 for ventilation, and a plurality of breathable holes 401 are evenly arranged on the breathable layer 4. It also includes a flame retardant coating 5. The side of the non-woven fabric base layer 1 away from the antibacterial fiber layer 2 is coated with a flame retardant coating 5 for flame retardancy. The flame retardant coating 5 is made of phosphorus or silicon flame retardant substances. The phosphorus flame retardant substances form phosphorus-containing compounds through hydrolysis reaction to absorb heat and prevent the spread of flames. The silicon flame retardant substances prevent the combustion of substances and the spread of fire through organic silicon compounds.

[0025] See also Figure 4 As shown, the antibacterial fiber layer 2 is composed of a nanosilver fiber layer 201, a kapok fiber layer 202 and a chitosan fiber layer 203. The nanosilver fiber layer 201 is provided with a kapok fiber layer 202, the nanosilver fiber layer 201 is bonded to the non-woven fabric base layer 1, the kapok fiber layer 202 is provided with a chitosan fiber layer 203, and the chitosan fiber layer 203 is bonded to the activated carbon fiber layer 3.

[0026] When the non-woven fabric is used to bandage the patient's wound, the breathable layer 4 is applied to the patient's wound. The breathable layer 4 can keep the wound in a permeable environment to avoid the growth of bacteria and contamination of the wound; the activated carbon fiber layer 3 can filter moisture and particulate impurities from the outside to avoid wound infection; the nanosilver fiber layer 201 in the antibacterial fiber layer 2 can continuously release nanosilver particles to exert its antibacterial properties, the kapok fiber layer 202 in the antibacterial fiber layer 2 can effectively kill bacteria such as Escherichia coli, and can effectively repel mites, and the chitosan fiber layer 203 in the antibacterial fiber layer 2 has good affinity and non-toxicity to proteins, has good antibacterial effects on various bacteria and fungi, inhibits bacterial growth, and interferes with normal cell metabolism; when a fire occurs, if the fire source is contaminated with the non-woven fabric, the flame retardant coating 5 can effectively slow down the fire and avoid the non-woven fabric from burning, preventing the fire from spreading and harming the patient.

[0027] Example 2: Based on Example 1, refer to Figure 2 and Figure 3As shown, it also includes an antistatic layer 6 coated on the top of the flame retardant coating 5 , and also includes an anti-ultraviolet coating 7 coated on the top of the antistatic layer 6 .

[0028] When using non-woven fabric, due to the friction generated by the non-woven fabric, the anti-static layer 6 can isolate the generated static electricity outside the non-woven fabric. When outdoors, the anti-ultraviolet coating 7 can reflect and absorb the ultraviolet rays in the sunlight to prevent the ultraviolet rays from penetrating the non-woven fabric.

[0029] See also Figure 2 and Figure 3 As shown, the bottom of the anti-ultraviolet coating 7 is coated with a wear-resistant layer 8 for protecting the non-woven fabric. The wear-resistant layer 8 is composed of a polyurethane coating. The polyurethane coating is soft and elastic, suitable for the use of non-woven fabrics, and has the characteristics of wear resistance, moisture resistance, and dry cleaning resistance; the top of the wear-resistant layer 8 is paved with a printing layer 9.

[0030] When the non-woven fabric rubs against the outside world, the wear-resistant layer 8 can protect the non-woven fabric body to prevent the non-woven fabric from being worn and penetrated. The printed layer 9 can be used to print flowers to make the non-woven fabric more beautiful and meet the individual needs of users.
