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.
本发明涉及一种多肽与化学纤维复合纤维及其制备方法,包括以下步骤:从天然蛋白原料中提取多肽或者人工合成多肽;将干燥的多肽粉末或者颗粒与具有熔融可纺性的化学纤维纺丝原料粉末或者颗粒混合均匀;经过熔融共混,制得多肽与化学纤维纺丝原料复合物;通过熔融纺丝工艺,制得多肽与化学纤维复合纤维。本发明还提供了一种多肽与化学纤维复合纤维,多肽的重量百分比为0.01-50%。本发明适用于多种多肽,原料价格低廉;在熔融共混纺丝过程中,不需要添加其他添加剂和溶剂,环境污染小,制备方法工艺简单,生产成本低;可生产含天然色素的绿色环保型复合物及纤维;选用不同的多肽和化学纤维原料可生产出种类繁多的复合物、短纤维和长丝。
