Embodiment 1
[0018] A kind of fluorescent yellow dyeing and multifunctional finishing method of acrylic fiber fabric, its process is as follows:
[0019] (1) Modification of acrylic fibers: Add modifier triethylenetetramine into treatment bath A, then put acrylic fibers into the above solution at a bath ratio of 1:10, and then raise the temperature to 120°C at a heating rate of 2°C / min , keep warm for 90 minutes, then cool down to 60°C at a cooling rate of 2°C / min, fully wash with water until the pH value is neutral, and dry or dry in the air;
[0020] (2) Dyeing and finishing the modified acrylic fiber: add acid fluorescent yellow 0.65% owf, berberine 2% owf, anionic ultraviolet absorber 2% owf, anti-precipitation agent 2g / L in treatment bath B, and adjust the pH to 4. Put the acrylic fiber modified in step (1) into the treatment bath at a bath ratio of 1:20, raise the temperature to 90°C at a heating rate of 3°C / min, keep it warm for 40 minutes, and cool down to 50°C at a cooling rate of...

Embodiment 3
[0042] A kind of fluorescent yellow dyeing and multifunctional finishing method of acrylic fiber fabric, its process is as follows:
[0043] (1) Modification of acrylic fiber: add modifier diethylenetriamine in treatment bath A, then put acrylic fiber into the above solution at a bath ratio of 1:30, and then raise the temperature to 110°C at a heating rate of 1°C / min , keep warm for 120min, then cool down to 60°C at a cooling rate of 1°C / min, fully wash with water until the pH value is neutral, and dry or dry in the air;
[0044] (2) Dyeing and finishing the modified acrylic fiber: add acid fluorescent yellow 0.85% owf, berberine 4% owf, anionic ultraviolet absorber 5% owf, anti-precipitation agent 4g / L in treatment bath B, adjust the pH to 4.5. Put the acrylic fiber modified in step (1) into the treatment bath at a bath ratio of 1:50, raise the temperature to 95°C at a heating rate of 3°C / min, keep it warm for 30 minutes, and cool it down to 50°C at a cooling rate of 4°C / min....
