Problems solved by technology

The traditional absorbent cotton gauze itself has no antibacterial and wound healing functions. Only after adding drugs on the surface of the absorbent cotton gauze, the absorbent cotton can disinfect and promote wound healing, but this additional effect is short-lived; and the absorbent cotton is in the process of preparation It needs to be treated with acid and alkali, which is highly corrosive and will cause great harm to the environment.
[0003] The existing patent document CN 106421872 A discloses a preparation method of medical gauze for promoting healing. It specifically discloses that a variety of inorganic raw materials are processed to make ceramic powder and then added to polyethylene terephthalate, and then melt-extruded The gauze is spun and then spun into gauze. The gauze in the patent document is the addition of inorganic materials to the chemical resin. If the chemical resin is used completely, it will easily cause allergies to the wound, and the added inorganic material is tightly wrapped in the chemical resin. The contact with the wound The area is small, so the effect of promoting healing is not obvious

Abstract

The invention relates to the technical field of processing of absorbent cotton and discloses absorbent cotton gauze to promote wound healing. The absorbent cotton gauze is made with 37-39 parts of cotton fiber, 11-13 parts of algal carbon fiber, 7-9 parts of chitosan fiber, and 5-7 parts of titanium dioxide suspension. The absorbent cotton gauze has an antibacterial rate of up to 92.1%, can avoidwound infections, promote blood circulation and quicken wound healing, enables wound healing time to be shortened by 20-25%, and allows therapeutic pain in a patient to be evidently relieved. Cotton fiber is soaked to quickly soften the surface fat and colloidal component of the cotton fiber, thereby facilitating late treatment and improving cotton fiber smoothness; an enzyme complex is added to carry out high temperature ultrasound treatment, lipase and pectinase are added to the enzyme complex, the surface fat and colloidal component of the cotton fiber are removed in mute state, and cottonfiber damage and environmental damage due to the use of traditional defatting methods using strong acids and alkalis are avoided; the absorbent cotton gauze is green; cotton fiber strength is improved.

Description

technical field [0001] The invention mainly relates to the technical field of absorbent cotton processing, in particular to an absorbent cotton gauze for promoting wound healing. Background technique [0002] Absorbent cotton refers to cotton that has been chemically treated to remove fat. It is made from raw cotton after removing impurities, degreasing, bleaching, washing, drying, and finishing. Absorbent cotton is easier to absorb liquid than ordinary cotton. It is a sanitary product and is also used to make nitrocellulose. Also known as cotton wool. The traditional absorbent cotton gauze itself has no antibacterial and wound healing functions. Only after adding drugs on the surface of the absorbent cotton gauze, the absorbent cotton can disinfect and promote wound healing, but this additional effect is short-lived; and the absorbent cotton is in the process of preparation The medium needs to be treated with acid and alkali, which is highly corrosive and will cause great ...
