ABSTRACT:
According to the present invention, an animal hair fiber can significantly be modified by fixing the supercontraction of the fiber which is a disadvantage in itself. The process for modifying the animal hair fiber according to the present invention comprises pretreating the animal hair fiber with a cleaving reagent for crosslinkage of the fiber and then treating the pretreated fiber with an supercontracting reagent. Furthermore, the process for preparing a bulky wool yarn according to the present invention comprises treating an mixed yarn with the supercontracting reagent, said mixed yarn consisting of the pretreated animal hair fiber with the cleaving reagent for crosslinkage of the fiber and a non-pretreated animal hair fiber.
