Embodiment 1
[0036] A high-efficiency dyeing and finishing process for aramid fabrics, comprising the following steps:
[0037](1) Modification treatment: Put the aramid fabric into the plasma equipment for plasma treatment, the discharge power is 100W, the discharge frequency is 13.56MHz, and the treatment time is 3min; then put it in a water bath for treatment, 2,3- Epoxypropyltrimethylammonium chloride 20g / L, montmorillonite 3g / L, chitosan 5g / L, sodium hydroxide 8g / L, isopropanol 15g / L, ultrasonic at 40℃ Ultrasonic treatment was carried out in a water bath for 1 min, the bath ratio was 30:1, and the ultrasonic frequency was 45 Hz. After the treatment, clean water was re-injected for 2 washes, and then dried;
[0038] (2) Scouring and dyeing in the same bath: Dye the aramid fabric after low-temperature freezing treatment, specifically: immerse the fiber fabric in the clear water of the dyeing machine at room temperature, and then add penetrant JFC 1.5g / L to the water bath to diffuse DN ...
