Abstract

The invention belongs to the technical field of reactive dyes, and particularly relates to a navy reactive dye formula with high color fastness to light, high composite color fastness to light and sweat and high color fastness to wet rubbing. After the navy blue reactive dye is used for dyeing, the prepared fabric is high in single-color light fastness, the CS color change grade of perspiration fastness acid perspiration, cotton staining and perspiration fastness alkali perspiration CS color change grade is high; the fastness to dry and wet rubbing is high; the dark blue reactive dye is low incost; brilliance of garment fabric is improved, compared with reduced (indanthrene) dye, the dye pollution is lower, the wastewater treatment pressure is lower, the overall production and applicationprocess is reasonable, effective, simple and rapid, and the dye can be efficiently and stably used on all-cotton fabric, cotton fiber and polyester fiber blended fabric and cotton fiber and polyesteramide fiber blended fabric.

Description

technical field [0001] The invention belongs to the technical field of reactive dyes, and in particular relates to a navy blue reactive dye formulation with high light fastness, high light-perspiration composite color fastness and high wet rubbing color fastness. Background technique [0002] Existing cotton fabrics, cotton fiber and polyester fiber blended fabrics, cotton fiber and polyamide ester fiber blended fabrics are the main types of clothing fabrics. At present, in addition to national flag red and other colors that require high brightness, the medium and dark fabric color solutions are only Dyed with vat (shihlin) dyes. [0003] But on the other hand, vat (shihlin) dye itself is insoluble in water and cannot be directly used for dyeing fabrics. It needs to be reduced to the sodium salt of leuco with a reducing agent such as hydrosulfite under alkaline conditions, and then absorbed On the fiber, and then oxidized by air or other oxidants to develop color, the leuc...
