摘　　要：探讨后区竹节纱纺制方法。从纺制方法、影响成纱风格机理、工艺参数配置、纺纱技术要点等方面对后区竹节纱纺制方法进行了分析与探讨。指出:后区竹节纱是区别于普通竹节纱的一种新型竹节纱,其特点是采用主、辅双粗纱分区喂入,通过控制后区牵伸倍数使辅粗纱产生竹节效果,然后与主粗纱并合牵伸形成一种新颖的竹节纱。与普通竹节纱相比,其织物具有新颖的模糊风格和色彩变幻特色。通过采用错位纺、合理选择后牵伸形式、遵循后牵伸最小原则以及主辅纱工艺各有侧重点等技术措施,可以获得较好的纺纱效果。Spinning method of back zone slub yarn was discussed. From aspect of spinning method,principle of effecting finish yarn style,setting of processing parameter,spinning technology key points et al, spinning method of back zone slub yarn was analyzed and discussed. It is pointed out that back zone slub yarn is one new style slub yarn and different to common slub yarn,the characteristic is adopting main and auxiliary double roving feeding, slub yarn effect was got from controlling back zone draft multiple of auxiliary roving then doubling with main roving to form a new style slub yarn. Comparing to common slub yarn,the fabric is new fuzzy style and the color is changing. Through adopting dislocation spinning and selecting proper back zone draft form, following principle of back zone draft least and focusing on different area to main ＆ auxiliary roving et al measures,better spinning effect could be got.
