Almost all fiber materials and their mixtures can be bleached and dyed. The biggest feature of the air-flow dyeing machine is that it greatly reduces the consumption of dyes, chemical auxiliaries and energy.

[0003] In the related art, reference can be made to the Chinese utility model patent with the authorization announcement number CN208933680U, which discloses an air-flow dyeing machine including a machine cylinder with a fabric discharging port.
