Abstract

La présente invention concerne un agent de traitement de fibre pouvant être utilisé pour traiter la surface d'une fibre qui comporte une membrane coquille d'oeuf soluble et un composé organique réactif ayant un groupe réactif. Lorsqu'une fibre est traitée avec l'agent de traitement de fibre ayant la constitution décrite ci-dessus, ladite fibre peut conserver les caractéristiques de la membrane coquille d'oeuf même après un usage prolongé sans perte des composants de la membrane coquille d'oeuf. Ainsi, la fibre peut présenter de manière continue une bonne tolérance et des caractéristiques avantageuses de rétention de l'humidité, d'absorption de l'eau, d'absorption de l'humidité, de traitement des plaies ainsi qu'une bonne caractéristique antistatique.
