Embodiment Construction
[0015] The technical solutions of the present invention will be described in further detail below in conjunction with specific embodiments.
[0016] The silk cold pad-batch dyeing method provided by the present invention can be specifically refined as: dye liquor preparation—dye liquor transportation (fabric preparation at the same time)—dye liquor padding—open width winding—coating—stacking ——Finishing; Among them:
[0017] 1. Dye solution preparation: the dye solution is dye solution and other auxiliaries:
[0018] 1) Dye liquid: the content of reactive dye is 1-200g / l, the dye is used according to the amount required for dyeing, and then put in the liquid storage barrel for later use.
[0019] 2) Auxiliary agent liquid: including penetrant 0~30g / l, cosolvent 0~100g / l, dyeing accelerator 0~200g / l, alkali agent 5~500g / l, according to the required amount of the dyeing process After softening the water, put it in another liquid storage bucket for use.
[0020] The penetrant ...
