本发明涉及种超短牛皮纤维的混纺包芯纱线、皮革基布及其生产方法，其纱线生产方法包括对牛皮边角料的纯物理打磨、揉搓及剥取，获得2-10mm的超短牛皮纤维，将该牛皮纤维合理预调湿后先与热熔纤维形成混合纤维层，然后利用无纺的铺层方式在该混合纤维层上下均铺涤纶短纤维层，最后进行截取开松，使三组分纤维混合均匀，再经梳理、分割、搓条成粗纱、粗纱并合后采用分梳摩擦加捻纺将该粗纱作为外包纱与低伸高强涤纶长丝形成该包芯纱线，其外包纱中超短牛皮纤维、热熔纤维及涤纶短纤维占混合纤维质量百分比为80-95％：2-10％：1-10％，该纱线织得的皮革基布经热压处理后具有良好的拉伸性能及撕破强力，其纵横向强力均匀稳定。 The invention relates to blended core-spun yarn made of ultra-short cowhide fibers, leather base cloth and production methods of the blended core-spun yarn and the leather base cloth. The production method of yarn includes: performing pure physical grinding, rubbing and stripping on cowhide leftovers to obtain the ultra-short cowhide fibers of 2-10mm, reasonably pre-conditioning the cowhide fibers, mixing the cowhide fibers with hot-melt fibers to form a mixed fiber layer, laying a polyester short fiber layer on each of the upper surface and the lower surface of the mixed fiber layer in a non-woven manner, cutting and opening to allow three kinds of fibers to be evenly mixed, carding, cutting and rubbing to obtain r
