Abstract: The invention relates to composite fibers of polypeptide and chemical fibers and a preparation method of the composite fibers. The preparation method comprises the steps of extracting polypeptide from a natural protein raw material or synthesizing polypeptide artificially; uniformly mixing dry polypeptide powder or particles with chemical fiber spinning raw material powder or particles with melt spinnability; performing melt blending to prepare a composite of polypeptide and the chemical fiber spinning raw material; preparing the composite fibers of polypeptide and chemical fibers through a melt spinning process. The invention also provides the composite fibers of polypeptide and the chemical fibers, wherein the weight percentage of the polypeptide is 0.01-50%. The composite fibers disclosed by the invention are suitable for a variety of polypeptides and are low in raw material price; during melt blending spinning, other additives or solvents are not required to be added, so that the environmental pollution is small; the preparation method is simple in process, and the production cost is low; an environment-friendly composite and fibers containing natural pigments can be produced; by selecting different polypeptides and chemical fiber raw materials, a wide variety of composites, staple fibers and filaments can be produced.
