The invention discloses a school uniform fabric production technology. The technology comprises pretreatment, polyester dyeing, first reduction cleaning, drainage, hot washing, water washing, second reduction cleaning, hot washing, cotton dyeing, fixation, softening, scutching wool washing machine-based water washing, drying, setting, detection, final inspection, and packaging/warehousing. A low temperature scouring and bleaching agent TF-189 is used, a treatment temperature is reduced by 25 DEG C from a high temperature 110 DEG C to a low temperature of 85 DEG C, a hot washing process is avoided, after treatment, whiteness, hair effects and dyeing effects are similar to those of the traditional oxygen bleaching process, energy consumption is reduced, polyester dying and reduction cleaning processes are combined because of the complementarity, the traditional sodium hydrosulfite alkaline reduction cleaning method is replaced by the technology provided by the invention, sodium hydrosulfite-caused pollution and damage are reduced, environmental friendliness is realized and energy saving and emission reduction effects are obtained.
