The correct method using fixing agents
Non-formaldehyde fixing agent property is evaluated according to the fixing result of dyed fabric: Dyeing and sampling→ fixing → the evaluation on the fixing agent: ①color changes in hue ②Wet fastness ③soap washing fastness ④perspiration fastness. ⑤crock-fastness ⑥chlorine fastness ⑦wet iron fastness ⑧light fastness ⑨ the influence of storage on the activated dyeing color fastness-quick test (Cribbage methods) 1. Dyeing and sampling: dye:2%(o.w.f) (commonly choose red, black and orchid); fabric : preliminary treated woven plain. Dyeing agent is according to the dyeing and sampling method. If it is applicable test in the factory, we can choose fabric with the lower fastness in the workshop. 2. Fixing: fixation process: fixing agent: 2%-4%(o.w.f) bath ratio:1:20, temperature: 40℃～60℃(according to the actual conditions in the fabric or the suggested using index of fixing agent); time: 20min; PH value: some fixing agent need correct PH value to ensure the best fixin...
