The invention provides a strong quick-dry pure-cotton knitted fabric and a production process thereof. The production process of the pure-cotton knitted fabric includes the steps: A, yarn treatment: dividing yarns into two parts, performing hydrophilic treatment on one part of yarns, and performing waterproof treatment on other part of yarns; B, weaving: weaving the treated yarns by the aid of a gross waterproof yarn and a gross hydrophilic yarn at intervals to obtain gray cloth; C, dyeing and finishing: performing gray cloth sizing, dyeing, soaping, drying and finished product sizing on the woven gray cloth to obtain the strong quick-dry pure-cotton knitted fabric. According to the production process, hydrophilic treatment and waterproof treatment of the yarns are performed, hole suction effects are formed by the aid of the weaving process of the gross waterproof yarn and the gross hydrophilic yarn at intervals, strong quick-dry effects are achieved by matching a dyeing and finishing process and additives, residual moisture is 10% 60 minutes before water washing, residual moisture is 10% after bearing washing for 10 times, and drip diffusion time is within 3 seconds before water washing and after water washing for 10 times.
