Abstract
The utility model relates to medical or civil chitosan antibacterial functional gauze, which comprises common gauze and a chitosan functional material coating layer, and the chitosan functional material coating layer formed by medical chitosan functional finishing agent through finishing is coated on the entire surface of the common gauze. Te chitosan antibacterial functional gauze has the technical points that the chitosan multifunctional finishing agent is prepared by chitosan, as well as cross-linking agent solution, and water in a volume ratio of 1:80 to 120; the gauze receives rolling, dehydration, and primary drying after being soaked in the solution (with a temperature of 25 to 40 degrees) for 2 to 10mins; and then the gauze receives rolling, dehydration, and secondary drying after being soaked in alkali surface-active agent (with a pH value of 9 to 11) solution (with a temperature of 25 to 40 degrees) for 2 to 10mins. The utility model has the advantages of bacteriostasis, comfort and softness, air-permeability and moisture absorption, deodorization, anti-ultraviolet function, innocuity, no stimulation, no corrosion, zero contamination, simple manufacturing technology, low cost and low product price.
Description
Technical field
This utility model relates to a kind of medical or civilian antibiotic multifunction gauze, the multi-functional gauze of a kind of specifically chitosan anti-bacteria.
Background technology
Chitosan [(1; 4)-and 2-amino-2-deoxidation-β-D glucosan] be chitin [(1; 4)-and 2-acetylaminohydroxyphenylarsonic acid 2-deoxidation-β-D glucosan] the natural biological polysaccharide molecule made through the alkali treatment deacetylate, be alkaline aminopolysaccharide unique in the natural polysaccharide, be a kind of Renewable resource.Contain great amount of hydroxy group and free amine group in its structure, have unique physiologically active and graceful function effect, but human body immunity improving power, the anti-infection ability of enhancing body.In addition, chitosan is by positively charged NH
3 +Adsorb electronegative cell wall, make chitosan be adsorbed on surface of cell membrane and form one deck polymeric membrane, changed the selection permeability of cell membrane, stop nutrient substance to intracellular transportation, cause Cytoplasm to run off, cell plasmolysis, thus play antibacterial and bacteriostasis.Therefore,, have good antibacterial bacteriostatic, ventilative moisture absorption, deodorization, anti-ultraviolet function, also can get rid of heavy metal, eliminate noxious substances such as formaldehyde, aromatic amine through the comfortable softness of gauze that the chitosan finishing agent is handled.
Chitosan is described as " biomaterial of 21st century ", and therefore fully the development and use chitosan is significant.Also occurred on the market in recent years utilizing the chitosan fibre forming property, spun out chitin fiber, made various fabrics such as gauze, its anti-microbial property excellence, but cost is high, has hindered the application of chitosan greatly, and the market share is also extremely low.
Summary of the invention
Technical problem to be solved by this invention is to overcome above-mentioned existing in prior technology weak point, and a kind of chitosan anti-bacteria function gauze is provided.
The technical solution used in the present invention is: a kind of chitosan anti-bacteria function gauze, its composition comprise common gauze and chitosan functional material clad, it is characterized in that the surface of described common gauze all is coated with chitosan anti-bacteria functional material clad.Chitosan and cross-linking agent solution and water are joined by volume 1: 80～120 make the chitosan multifunction finishing agent, gauze is at this solution (25 ℃～40 ℃), rolling, take off liquid, first drying; Again gauze is soaked 2～10min in basic surface activating agent (pH is 9～11) solution (25 ℃～40 ℃), rolling, take off liquid, stentering forming, secondary drying.
The invention has the beneficial effects as follows: (1) antibacterial bacteriostatic effect is obvious, and the bacteriostasis rates of antibacterials such as staphylococcus aureus, Klebsiella pneumonia is reached more than 99.9%, can effectively reduce the wound infection rate, promotes wound healing; (2) comfortable softness has high ventilation moisture absorption, deodorization, anti-ultraviolet function, also can get rid of heavy metal, eliminates noxious substances such as formaldehyde, aromatic amine; (3) pH is neutral, in use can effectively avoid causing nerve injury, and nontoxic, tasteless, non-stimulated, do not have corrosion, pollution-free, belong to environmentally friendly, the medical grade product; (4) the low-molecular weight chitoglycan auxiliary agent of this utility model employing is the pure-natural biological matter of extracting from the shrimp Eriocheir sinensis, and environment-friendly high-efficiency does not have any injury to human body, and raw material sources are abundant; (5) this utility model technology is simple, practical, need not to purchase large number quipments, and cost is low, easily realizes extensive industrialization, and product price is cheap.
