Document Type and Number:
WIPO Patent Application WO/2020/097981
Kind Code:
A1
Abstract:
Disclosed in the present invention are flame-retardant silk prepared from flavone and a metal salt, a preparation method therefor, and application thereof. The method comprises the following steps: selecting a natural micromolecular flavone compound of which the structure at least meets one of three conditions that ring C contains 3-hydroxy, ring A contains 5-hydroxy, and ring B contains 3'-hydroxy and 4'-hydroxy, and treating silk at 2.5-3.5 pH and 70-90°Ϲ with a dipping adsorption method; and then dipping the silk into a metal salt solution having a 1-5 g/L concentration, treating the silk at 50-70°Ϲ with the dipping adsorption method, and performing washing and drying after the treatment is completed, thereby obtaining durable flame-retardant functional silk. In the present invention, a silk fabric having good flame-retardant performance is prepared from a natural plant extract and a metal salt, so as to avoid environmental pollution caused by using a traditional flame retardant containing nitrogen, phosphorus and halogen elements in production and use processes. The present invention has the advantages of being efficient, environmentally friendly, simple, and feasible.
