The invention discloses a production process of a knitted fabric. The production process comprises the following steps: adding 1 to 5 parts by mass of hydroxypropyl methyl cellulose, 3 parts by mass of a guanidine antibacterial, 5 parts by mass of polyoxyethylene polyamine, 2 parts by mass of nano magnesium hydroxide into 20 to 50 parts by mass of deionized water, mixing, and uniformly stirring; then slowly adding one part by mass of sorbitan fatty acid ester, 2 parts by mass of herba schizonepetae volatile oil, 3 parts by mass of tetramethylolphosphonium chloride and one part of aloe rheochrysin, continuously stirring, sufficiently and uniformly mixing to obtain a finishing solution; and performing the antibacterial treatment. By adopting a post-production process of a hat knitted fabric,the finished fabric has excellent flame-retardant performance, antibacterial performance, anti-crease performance and antistatic performance and high washing fastness, can improve the antibacterial performance of the fabric, has good antibacterial effect and is long in service life.
