▎ 摘　　要

NOVELTY - Post-processing fiber product comprises dipping the fiber product into graphene material dispersion liquid, raising temperature to high elastomeric state temperature of the fiber material and constant temperature for composite processing, taking out, cooling and drying to obtain composite fiber product. USE - The product is useful for producing textile, underwear, protective clothing, thermal clothes and socks (claimed). ADVANTAGE - The method: improves conductivity of fiber product; enhances far infrared performance of fiber product; and realizes graphene uniformly distributed on the fiber.
