Abstract
The invention discloses a method for preparing an anti-flaming silk. The method comprises the following steps: preparing dioscorea cirhosa extract; utilizing a dipping adsorption method to absorb thecondensed tannin in the dioscorea cirhosa extract to a silk fabric, thereby acquiring a dioscorea cirhosa extract modified silk fabric; utilizing the dipping adsorption method to absorb a polypropylene imine dendrimer to the dioscorea cirhosa extract modified silk fabric under a weak alkaline condition, thereby acquiring the anti-flaming silk. According to the invention, the cross-linking reactionof the condensed tannin in the dioscorea cirhosa extract and the polypropylene imine dendrimer on the silk fabric under the weak alkaline condition is utilized to effectively promote the flame resistance of the silk fabric. The silk fabric finished according to the method provided by the invention has a durable anti-flaming function.
