The invention discloses a production technology of air spinning cotton core filament covering yarn.The production technology comprises the following technological steps that 1, core filament fibers are prepared into core filaments through cotton opening and scotching, cotton carding, drawing and doubling and air spinning; 2, outer wrapping fibers are prepared into skin yarn through cotton opening and scotching, cotton carding, drawing and doubling and rough yarn obtaining; 3, the core filaments obtained in the step 1 and the skin yarn obtained in the step 2 are fed into a covering yarn device arranged in ring spun yarn equipment to be prepared into covering yarn; 4, the covering yarn is prepared into the finished air spinning cotton core filament covering yarn through a winding process, wherein cotton fibers are adopted as the core filament fibers.According to the preparation technology of the covering yarn, air spinning cotton yarn is adopted as the core filaments, and therefore the finished yarn is high in hygroscopicity, good in dyeing performance, soft in handfeel, comfortable to wear, simple in appearance, not prone to worm damage, firm and durable; due to the fact that the air spinning yarn is high in fluffy degree, the finished yarn obtained by wrapping the air spinning yarn through ring spinning has the unique style of being soft outside and rigid inside, and a fabric is stiff and smooth and comfortable.
