The invention relates to the technical field of sock production processes, in particular to a production process of sweat-absorbent breathable sports socks. The production process of the sweat-absorbent breathable sports socks comprises the following steps that 1, yarn is prepared; 2, the yarn is softened; 3, the socks are prepared; 4, the socks are disinfected; 5, afterfinishing is carried out on the socks; 6, the socks are checked and packaged. The sports socks are reasonable in design, fine, smooth and soft in hand feeling and good in comfort, deodorization and wear resisting are achieved better, and friction force is reduced; the socks are ultrathin and breathable, super-good elasticity is achieved, sweat absorption and wet permeability are better, the feet are not covered tightly, and the socks are easy to wash and fast to dry, solid and durable, and not likely to deform.
