双色仿牛仔织物液体硫化染整工艺

Wet processing of denim-like fabric with liquid sulfur dyes

介绍了纯棉织物仿牛仔染整工艺,采用连续平幅前处理工艺,注意酶退浆的化料温度、pH值和用水硬度;阳离子改性剂PNT改性时,注意逐步升温焙烘;采用液体硫化Diresul RDT系列染料染色,在保持牛仔仿旧感、丰富其色彩的同时,解决了其色牢度差的问题,还可节省染料、蒸汽和水,体现了节能减排、清洁生产的特点。

Wet processing of denim-like fabric was introduced. Denim-like fabric was pretreated in continuous open-width form, modified with cationic modification agent PNT, and dyed with liquid sulfur dyes Diresul RDT. Worn-out appearance of denim-like fabric was kept and color varieties were enriched after the treatment. This process not only saved dyes, steam and water, but also showed characteristics of energy saving, emission reducing and clean production.
