【摘要】 本文通过对摩擦纺前纺工艺试验研究，探讨了摩擦纺的成纱质量与前纺工艺的关系，揭示了摩擦纺原料及前纺棉条的性能对成纱质量的影响不同于环锭纺的特殊规律。从而得出摩擦纺生产中可以用生条代替二并条甚至精梳条，而不会影响成纱质量。更多还原

【Abstract】 Relations between yarn quality and pre-spinning preparation are analysed here for frictionalspinning,from that,the paper reckons out a special yarn quality regularity affected by assortmentof raw materials and sliver,and concludes that card sliver could be used in stead of intermediate orcombed sliver更多还原
