(2) Washing the treated cotton-containing fabric obtained in the step (1) with water for 4-15 min at 40-70 ℃, washing the fabric with water for 4-15 min, repeatedly washing the fabric with water for 2-5 times, and performing scouring bleaching, wool etching and dyeing treatment on the fabric to obtain the cotton-silk-containing smooth fabric;
the mercerizing agent is mercerizing agent solution;
the mercerizing agent comprises a combination of sodium hydroxide and a penetrating agent;
the concentration of sodium hydroxide in the mercerizing agent solution is 8-30 Baume degrees.
2. The method of claim 1, wherein the osmotic agent is a strong base resistant osmotic agent.
3. The production method according to claim 1, wherein the mass content of the penetrating agent in the mercerizing agent solution is 0.3-2 g/L.
