The invention relates to the technical field of textile, and particularly discloses an ultra-smooth composite short fiber and a preparation method and application thereof.The ultra-smooth composite short fiber is prepared from, by weight, 40-60 parts of PE master batch and 40-60 parts of smooth PET master batch; the smooth PET master batch is prepared from porous PET resin and a slipping agent. According to the invention, the slipping agent is adsorbed by the porous PET resin, so that the smoothness and hydrophilicity of the PET master batch are improved, and the smoothness and hygroscopicity of the super-smooth composite short fiber are further improved. 本申请涉及纺织技术领域，具体公开了一种超爽滑复合短纤维及其制备方法及应用，超爽滑复合短纤维，包括以下重量份的原料：PE母粒40-60份，爽滑PET母粒40-60份；所述爽滑PET母粒为多孔PET树脂与爽滑剂制备而成。本申请通过多孔PET树脂吸附爽滑剂，改善PET母粒的滑爽性和亲水性，进而提高了超爽滑复合短纤维的滑爽性、吸湿性。
