Vortex spinning process

The invention relates to the technical field of cotton spinning, and provides an air vortex spinning technology which comprises the steps that raw cotton is grabbed through a cotton grabbing machine, and bunchy fibers are obtained; carding the bundle-shaped fibers through a carding machine to obtain strip-shaped fibers; uniformly mixing the strip-shaped fibers through a drawing frame to obtain strip-shaped cotton; cleaning the surface of the strip-shaped cotton through a water tank, stretching the cleaned strip-shaped cotton through a traction device, and standing; the strip-shaped cotton obtained after standing is guided into a vortex spinning machine to be spun, and vortex yarn is obtained; and the guided-out vortex yarn is dried through drying equipment. The strip-shaped fibers are cleaned through clean water, dust, defects and velveteen on the surfaces of the strip-shaped fibers can be further removed, meanwhile, the fiber velveteen on the surfaces of the wet strip-shaped fibers can be attached to strip-s
