description The invention relates to a manufacturing process of a coarse denier air covered yarn, which comprises the following steps that: spandex is stretched through two draft rollers, the drafting ratio is 1.5 to 3.0, and the drafting tension is 8 to 15CN; at the same time, coarse denier spandex filament yarns are added and are stranded by a yarn guide, the stranded yarns enter an air interlacing jet for cohesion, the interlacing air pressure is 2.0 to 4.0 Pa, and the number of interlacing points is controlled between 75 and 100 per m; and after cohesion, the yarns are coiled to be molded, and the coiling speed is between 200 and 400 m/min. The coarse denier air covered yarn manufactured by the invention is 300 to 1200 denier, and is mainly used for manufacturing canvas or denim, and the fabric is thicker and more durable.
