The invention relates to a super-draft spinning method. Twisted fiber ribbons sequentially pass through a rear draft region, a middle draft region and a front draft region; double-rubber-ring draft isrespectively adopted in the rear draft region and the front draft region, simultaneously, aggregation is carried out in the middle draft region and a draft multiple of the middle draft region is controlled into 1 to implement super draft; a free region is formed between a rear roller jaw and a double-rubber-ring jaw in the rear draft region; a free region is formed between a front roller jaw andthe double-rubber-ring jaw in the front draft region; the free regions mean regions which are not applied with friction; and a double-rubber-ring draft system mainly comprises an upper pin frame and alower pin rod which are arranged up and down and matched with each other, a tensioner arranged laterally below the lower pin rod, an upper rubber ring sleeving a middle leather roller and the upper pin frame, and a rear lower rubber ring sleeving a middle roller, the lower pin rod and the tensioner. The method disclosed by the invention implements super draft of yarns in the premise of ensuring yarn quality, and has very high popularization value.
