Embodiment 1
[0028] A method for arranging cotton bandages with antibacterial and antifouling microcapsules is characterized in that it comprises the following steps, and the following raw materials are by weight:
[0029] (1) Fluorosilane treatment process for cotton bandages:
[0030] Mix 1 part of low surface energy finishing agent 1H, 1H, 2H, 2H-perfluorooctyltriethoxysilane, 99 parts of absolute ethanol and 100 parts of deionized water, add dropwise glacial acetic acid to adjust the pH to 3, After hydrolysis for 30 minutes, soak the cotton bandage treated with alkali reduction at a bath ratio of 1:40, shake it in a water bath at 90°C for 2 hours, and take out the cotton bandage treated with fluorosilane;
[0031] Among them, the alkali reduction treatment process of cotton bandages: heating the sodium hydroxide solution with a mass concentration of 25g / L to 75°C in a water bath, immersing the pretreated cotton bandages in it at a bath ratio of 1:30, and adding 1 part of accelerator 2g...

Abstract
The invention discloses a method for finishing a cotton cloth bandage through antibacterial antifouling micro-capsules. A finishing agent with low-surface-energy, absolute ethyl alcohol and deionizedwater are sufficiently mixed, after glacial acetic acid is dropped for hydrolysis, the cotton cloth bandage treated by alkali decrement is soaked with the mixture, and water bath oscillation is performed to obtain the cotton cloth bandage treated by fluoroalkyl silane; an arabic gum powder solution is added into barbaloin std-graphene oxide-glycine betaine composite gel to be stirred and dissolved, a water-soluble chitosan solution is dropped, magnetic stirring is performed in a constant temperature water bath, distilled water of the same temperature and same volume is added and mixed to be uniform, constant temperature stirring and composite cohesion are performed, cooling is performed, glutaraldehyde is added for a cross linking curing reaction, standing filtering and vacuum freeze drying are performed to obtain antibacterial antifouling micro-capsules; the antibacterial antifouling micro-capsules are added into water, magnetic stirring is performed in the water bath, a penetrant isadded to obtain an antibacterial antifouling finishing solution, and the cotton cloth bandage treated by fluoroalkyl silane is subjected to dipping, rolling, secondary dipping, secondary rolling, pre-baking, baking, soaping, washing and natural drying in the finishing solution to obtain the cotton cloth bandage obtained after antibacterial antifouling finishing.
Description
technical field [0001] The invention belongs to the field of bandages, and in particular relates to a method for arranging cotton bandages with antibacterial and antifouling microcapsules. Background technique [0002] In orthopedic treatment, "immobilization" with bandages is an important surgical measure. At present, plaster bandages have been widely used for more than 100 years, but there are still many shortcomings in clinical application of plaster bandages, such as slow curing, bulky and fragile, poor air permeability and X-ray permeability, and cannot enter water after hardening Wait. Therefore, foreign countries have developed "medical polymer bandages" to replace traditional plaster bandages since the 1970s, and have achieved good results in clinical use. The medical polymer bandages in the prior art have the defects of poor stain resistance and antibacterial effect, and are easily polluted by stains during use, thereby easily causing wound infection.
