The invention discloses a production technology of a fluorescent cotton fabric. The production technology is characterized by comprising the steps of 1, modification treatment of the cotton fabric, wherein the cotton fabric is immersed in a 18 g / L modifying agent solution, the pH is 10, the bath ratio is 30:1, the initial temperature is 30 DEG C, heating is conducted to 70 DEG C at the speed of 5 DEG C / min, the temperature is kept for 20 min, heating is conducted to 90 DEG C at the speed of 1 DEG C / min, the temperature is kept for 20 min, and the treated cotton fabric is taken out, washed with water and air-dried at
room temperature; 2, treatment, wherein the cotton fabric is immersed in
warm water of 60 DEG C for 30 min, and then the cotton fabric is taken out and air-dried at
room temperature; 3, dye preparation, wherein
sodium carboxymethylcellulose is added into water, stirring is conducted for 12 h to 24 h, water-soluble fluorescent dye is slowly added, and the materials are stirred and mixed to be uniform; 4, fluorescent
dyeing, wherein the cotton fabric treated in the second step is immersed into dye prepared in the third step for
dyeing, the pH ranges from 5 to 6, the bath ratio is 30:1, the initial temperature is 30 DEG C, heating is conducted to 60 DEG C at the speed of 5 DEG C / min, the temperature is kept for 20 min, heating is conducted to 90 DEG C at the speed of 1 DEG C / min, the temperature is kept for 50 min, and then the cotton fabric is taken out and air-dried.
