Technical Field

The invention relates to the field of medical dressing materials, in particular to antibacterial reticular gauze for burns and scalds.

Background

Clinically, burn and scald wounds are often characterized by much seepage, easy infection and difficult healing, which is caused by the fact that the surfaces of the burn and scald wounds are a warm and humid environment and pathogens such as staphylococcus aureus, candida albicans, escherichia coli and the like are rapidly propagated on the wounds. In order to control bacterial reproduction of burn and scald wounds and prevent wound infection, a large number of medical dressings are widely used, and antibiotics or various antibacterial materials are considered to be added to assist in protecting the wounds, reducing infection, absorbing secretion, keeping the body mild and promoting wound healing. Among them, the silver-based antibacterial agent has been widely regarded for its excellent antibacterial property, no drug resistance and biocompatibility, and its application in medical dressing for burn and scald is widely appreciated.

Although the silver-containing antibacterial gauze mesh is applied to the treatment of burn and scald wounds, the characteristic of easy adhesion exists in the use process because the hairiness rate on the surface of gauze yarns is not considered; the selection of a processing technology is not considered, and the characteristics of high impurity content of the mesh gauze are high; the problems of seepage and the like are not considered due to the size of meshes, even the antibacterial effect cannot meet the expected requirement and the like, and the popularization and application of the silver-containing antibacterial reticular gauze are influenced to a certain extent. Therefore, aiming at the problems, silver-containing antibacterial gauze with low impurity content, small adhesion, easy seepage of seepage liquid, proper hardness and softness and excellent antibacterial performance needs to be designed and prepared so as to meet the requirements of treating burn and scald wounds.

Disclosure of Invention

The invention aims to provide silver-containing antibacterial mesh gauze which is low in impurity content, small in adhesion, easy to seep seepage liquid, proper in hardness and softness and excellent in antibacterial performance after nano silver particles or silver ions are adsorbed on the surface of a 21s or 40s compact spinning pure cotton yarn and a 24 × 20 or 36 × 18 warp-weft density woven pure cotton gauze which is used as a base material.

The invention is mainly realized by the following technical scheme: the antibacterial reticular gauze for burns and scalds adopts pure cotton gauze as a base material, and nano silver particles or silver ions of 800-2000 mg/kg are adsorbed on the surface of the gauze. The pure cotton gauze is woven by 21s or 40s yarns, and the yarns are spun by a compact spinning process by taking high-quality long stapled cotton as a raw material; weaving by adopting a twisting weaving process at a warp and weft density of 24 multiplied by 20 or 36 multiplied by 18; the warp yarns are prepared by adopting a pure starch sizing process in the weaving process and adopting a biological enzyme desizing process after weaving is finished. The antibacterial reticular gauze for burns and scalds is obtained by dipping or padding the pure cotton gauze in silver-containing antibacterial solution and drying.

Because the antibacterial reticular gauze for burns and scalds adopts the compact spinning process to spin yarns and adopts the pure starch sizing and biological enzyme desizing processes, the antibacterial reticular gauze is purer, and has low hairiness rate and less wound adhesion; the appropriate yarn thickness ensures the softness and certain rigidity of the antibacterial reticular gauze; the proper longitude and latitude density ensures the seepage of the exudate on the surface of the burn wound; the nano silver particles or silver ions adsorbed on the surface endow the mesh gauze with excellent antibacterial performance.

The structure of the present invention will be further described by way of examples with reference to the accompanying drawings.

Example (b): as shown in figure 1, the invention relates to antibacterial reticular gauze for burns and scalds, which is prepared by using high-quality long stapled cotton as a raw material, spinning 21s or 40s yarns by adopting a compact spinning process, and weaving by using a 24 x 20 warp-weft density twisting process, wherein the 21s compact spun yarns are used as weft yarns 2, the 40s compact spun yarns are used as warp yarns 1, and pure starch sizing and biological enzyme desizing processes are adopted in the weaving and desizing processes to obtain pure cotton reticular gauze. And (3) padding 500mg/kg of silver-containing antibacterial solution on the pure cotton mesh gauze obtained by the process, and drying to obtain the antibacterial mesh gauze for burns and scalds. The antibacterial gauze for treating burn and scald can be used for treating burn and scald wound by cutting, packaging, and sterilizing.

The foregoing is not intended to limit the practice of the present application to the particular forms set forth herein. For those skilled in the art to which the present application pertains, several simple deductions or substitutions can be made without departing from the inventive concept of the present application, but all of them belong to the protection scope of the present invention.
