Abstract

Une solution de filage d'une fibre contenant des protéines, absorbant les ondes, faisant écran et absorbant la chaleur est composée d'une ou plusieurs protéines, d'un ou plusieurs alcools polyvinyliques, d'un ou plusieurs composés hétérocycliques et d'une ou plusieurs substances contenant un métal. La composition de la solution de filage est de 1-90 parties en poids d'une ou plusieurs protéines, 99-10 parties en poids d'un ou plusieurs alcools polyvinyliques, 0,001-23 parties en poids d'un ou plusieurs composés hétérocycliques et 0,001-23 parties en poids d'une ou plusieurs substances contenant un métal. L'invention concerne également des procédés servant à préparer la solution de filage. La fibre formée à partir de ladite solution de filage a des propriétés avantageuses, telles qu'une conductivité de l'humidité agréable pour la peau et une résistance à l'usure, en plus des propriétés d'absorption des ondes, d'écran et d'absorption de la chaleur. Les produits peuvent supporter une longue durée d'utilisation ou de multiples cycles de lavage sans dégradation de leurs propriétés fonctionnelles.
