The present invention discloses a
polymer composite function fibers containing partial
graphene, and a preparation method thereof. The fibers comprise a component A and a component B, wherein the component A and the component B are combined in a partial exposing manner, side-by-side manner or
skin-core manner, and 20-100% of the outer area of each
fiber is the component B. The method comprises: crystallizing a
polyester containing 0.1-1 wt% of partial reducing
graphene and a
polyester containing 4-20 wt% of a nanometer composite filler containing partial reducing
graphene and TiO2,
drying, carrying out melt composite
spinning, and carrying out drawing and relaxation
heat setting at a temperature of 80-160 DEG C, and reducing the partial graphene in the fibers to achieve the carbon /
oxygen atom ratio of 9 / 1-15 / 1 through the reducing treatment. According to the present invention, the prepared fibers can be produced at the high
spinning speed, and the production efficiency is high; and the fibers have characteristics of low single
fineness, high strength and lower resistivity, meets the antistatic requirement, and further has characteristics of anti-bacterial property and
flame retardant property so as to provide good application prospects.
