直接染料染色工艺Dyeing Process of Direct Dyes

■匀染剂：雷米邦A(或净洗剂613)用量      ■Dosage for levelling agent of Leimibang A (or detergent 613)

●浅色: 1.5-2.0, g/l                                     ●Pale: 1.5-2.0, g/l

●中色: 1.0-1.5, g/l                                      ●Medium: 1.0-1.5, g/l

●深色: 0.5-1.0, g/l                                      ●Deep: 0.5-1.0, g/l

■平平加也可以作为匀染剂，但用量须减少1/2。无论使用何种匀染剂，最好在加入染料之前加入，以确保染色均匀。

■Reduce the dosage by 1/2 when using Pingpingia as a levelling agent, and add the levelling agent before dyestuff to avoid dyeing defect.

■促染剂(元明粉)的用量                                 ■Dosage of Accelerating agent(Na2SO4)

●浅色: 2.0-5.0, g/l                                     ●Pale: 2.0-5.0, g/l

●中色: 5.0-10, g/l                                       ●Medium: 5.0-10, g/l

●深色: 10-20, g/l                                        ●Deep: 10-20, g/l

■促染剂最好在染色中加入，以免造成初染率过高而产生色花。有时，也可以用食盐，但用量须减少1/2-1/3。

■Add the accelerating agent in the halfway of dyeing to avoid a high initial dyeing-rate, which may cause dyeing defect. Sodium Chloride can be used as an accelerating agent sometimes, but the dosage must be reduced by 1/2-1/3.

■固色处理                                                    ■Color fixing

●固色剂用量: 0-4.0% (o.w.f.)                         ●Dosage of Color fixing agent: 0-4.0% (o.w.f.)

●浴比: 1:10-20                                             ●Bath ratio: 1:10-20

●PH(用HAC调节): 6.0                                  ●PH(to adjust with HAC):6.0

●温度与时间: 50℃ & 20Min.                      ●Temperature & Time: 50℃ & 20Min.

●染色后织物上的浮色必须充分洗净，避免在带有碱性的情形下固色。
