摘要
以天然植物石榴皮染料为原料,对蚕丝欧根纱的染色工艺进行探索,通过比较5种染色法,确立大生产采用三步法染色工艺。改性工艺为：浴比1∶40,改性剂质量分数10%（omf）,pH 7,升温至85℃,保温30 min,清水洗涤2次。染色工艺为：浴比1∶40,秋香黄染料质量分数为4%（omf）,纯碱质量浓度0.5 g/L,pH 7-8,升温至85℃,保温30 min,清水洗涤。皂洗过程工艺为：浴比为1∶40,中性皂洗剂质量浓度1 g/L,升温至60℃,皂洗10 min,水洗。三步法工艺的实验室小样与工业化大样生产同效,重现性好。
The natural plant pomegranate peel dye is taken as raw material, the dyeing process of silk organza is explored. By comparing five dyeing methods, the three-step dyeing process is established for large-scale production. The modified process is as follows： bath ratio1 ∶ 40, modifier dosage 10%（omf）, pH value 7, modification at 85℃ for 30 min, following by twice washing. The dyeing process is asfollows： bath ratio 1 ∶ 40, dyestuffs 4%（omf）, soda ash 0.5 g/L, pH value 7- 8, dyeing at 85℃ for 30 min. The soaping process is asfollows： bath ratio 1 ∶ 40, neutral soap lotion 1 g/L, soaping at 60℃ for 30 min. The three-step process of the laboratory sample and the industrialization of large-scale production have the same effect and good reproducibility.
