The invention discloses a nylon fabric
dyeing process which comprises the following steps: (1) performing cold pad-batch treatment on a fabric; (2) performing
desizing treatment; (3) performing cold impregnation; (4) feeding the fabric subjected to cold impregnation into a
dyeing machine, and
dyeing; (5) fixing the dyed fabric, wherein the initial temperature is 30-40 DEG C, the fixing temperature is 80 DEG C, the fixing time is 20-25 minutes, a fixing agent is A-12 and NS-1, and the concentration of the fixing agent is 2-4g / L; and (6) finally setting, wherein the setting temperature is 145-155 DEG C, and the
setting time is 0.5-1 minute. According to the invention, a fabric can be directly put in a dye vat and dyed, the fabric can not be creased or scratched in the dyeing process so as to avoid crease marks, the traditional wrapping method does not need to be used, and the production efficiency is greatly improved; and the fabric has better dyeing effect, and the dye has better permeability in the fabric. Thus, the finished product has less
color difference, thereby omitting the reworking and shading step, saving manpower and
material resources and improving the quality of the finished product.
