The present invention belongs to the technical field of
fiber materials, and relates to a composite
fiber containing nano natural tea fibers, and a preparation method and application thereof. The raw materials for preparing the composite
fiber include nano natural tea fibers and basic fiber pulp, and the nano natural tea fibers are mate nano fiber microemulsions. The present invention integrates
nanotechnology into the preparation of natural tea fibers, and adopts a
microemulsion method to simultaneously and evenly disperse a variety of effective ingredients in tea in the mate nano fiber
microemulsion, so that the multifunctionality of the fabric can be effectively exerted; the
microemulsion system has high uniformity and long-term stability, and during the
spinning process, the nano tea fibers can be highly dispersed in the
spinning solution without the need for additional surfactants, and the effect of the functional fabric finally obtained can be long-lasting. In addition, mate tea is rich in tea polyphenols and unique yerba mate alkaloids, which can further improve the comprehensive performance of the composite fiber.
