Abstract
(EN)
Disclosed is a method for preparing a flame retardant silk, the method comprising the following steps: soaking silk in a tannic acid solution with a pH value of 3-4, and raising the temperature to 80-90℃ for a temperature holding treatment; and soaking the treated silk in a 2-6 g/L metal salt solution, and raising the temperature to 50-70℃ for a treatment to obtain the flame retardant silk. The method of the present invention endows silk with excellent flame retardant properties without adding any traditional flame retardants containing nitrogen, phosphorus or a halogen element, and can avoid the environmental pollution problems caused by nitrogen, phosphorus and a halogen element during the production and use of a flame retardant silk and after the flame retardant silk is abandoned due to the use of a traditional flame retardant. The method has the advantages of being environmentally friendly, highly efficient, and simple and easy to operate.

La présente invention concerne un procédé de préparation d'une soie ignifuge, le procédé comprenant les étapes suivantes : tremper la soie dans une solution d'acide tannique avec une valeur de pH de 3-4, et élever la température à 80-90 °C pour un traitement de maintien de température ; et tremper la soie traitée dans une solution de sel métallique de 2 à 6 g/l, et élever la température à 50-70 °C pour un traitement permettant d'obtenir la soie ignifuge. Le procédé de la présente invention confère à la soie d'excellentes propriétés ignifuges sans ajouter d'agents ignifuges classiques contenant de l'azote, du phosphore ou des halogènes, et permet d'éviter les problèmes de pollution environnementale provoqués par l'azote, le phosphore et les halogènes pendant la production et l'utilisation d'une soie ignifuge et après que la soie ignifuge est abandonnée en raison de l'utilisation d'un retardateur de flamme classique. Le procédé présente les avantages d'être respectueux de l'environnement, extrêmement efficace, simple et facile à utiliser.
