To provide a method for producing blended yarns by ring spinning with mixed raw materials of kapoks.
In the method the mixed raw materials of kapok fibers and other fibers are subjected to the processes of scutching, carding, drawing, roving, spinning, etc., and a device of guiding cotton sliver is provided after a carding procedure, wherein the spinning adopts a double-short-apron drafting mode, the carding is performed twice, and the drawing is performed twice. The blended yarns produced according to the inventive method have the superior technical indexes in terms of the single yarn breaking tenacity, single yarn elongation at break, etc. which are better than the industrial standard of cotton berber yarn. And the fabric produced from the product of the invention has the superior technical indexes in terms of the fabric heat retention, fabric moisture vapour transmission, fabric touching cold-warm feeling, fabric bulking intensity, fabric compressive elastic recovery ratio and fabric soft draping property, etc. which are better than those of the similar products such as the pure cotton and polyester cotton, etc.
