摘要：对比分析了新疆机采棉与手采棉的质量差异，以及二者在清梳联、梳棉、精梳及成纱中存在的质量控制指标差异；指出：新疆机采棉虽然采摘成本降低，但是异性纤维多，短绒率高，在相同的工艺条件下无论是生产普梳纱还是精梳纱，其质量都远远落后于手采棉；进一步弄清新疆机采棉在纺纱过程中与手采棉的差距，是改进新疆机采棉在实际纺纱生产中存在问题的主要手段，也是调整采棉工艺参数、优选纺纱器材专件的关键；在特殊纺织品面料生产时，合理制定纺纱工艺，充分发挥新疆机采棉特点，亦是指导新疆机采棉进行改进、发展的重要手段。

  Abstract:Quality comparative analysis is done of the differences in Xinjiang machine-picked cotton and hand-picked cotton,as well as the index difference in quality control in the processes of clear-carding combination,carding,combing and the resultant yarn.It is pointed out that the Xinjiang machine-picked cotton is of low cost in harvest,but there are varieties of foreign fibers with high rate of staple fiber.Under the same conditions,production of either carded yarn or combed yarn prove that the Xinjiang machine-picked cotton is far inferior to the hand-picked cotton in yarn quality.Making clear the difference in-between is the key to the solution of the problems existing in the yarn production practice.It is also important in regulating the index of cotton picking and the optimization of textile accessories. Another important means guiding modification and development of Xinjiang machine -picked cotton lies in proper deciding spinning process and making full play of Xinjiang machine-picked cotton in production of special textile materials.
Key Words:Xinjiang machine-picked cotton;hand-picked cotton;clear-carding combination;carding;combing;harmful fiber;anisotropic fiber film
