Flame-retardant silk and its preparation method and application

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.

Description

technical field

[0001] The invention relates to the technical field of textile finishing, in particular to a method for improving the flame-retardant performance of silk, flame-retardant silk and applications thereof. Background technique

[0002] Nearly half of the fires in the world are caused by the burning of textiles, and the fire fatalities caused by textiles and interior decorations rank first. Silk is a natural protein fiber, which has the characteristics of moisture absorption, breathability, softness and smoothness, soft luster, elegance and gorgeousness, and comfortable wearing, so it is very popular and loved by people. Silk fiber is often widely used to make high-grade bed textiles, interior decoration fabrics, carpets, curtains, wall coverings and textile artworks, etc. These silk products have certain requirements for flame retardancy. Although silk itself has a certain flame retardancy compared with cellulose fiber, its limiting oxygen index is generally onl...
