Example Embodiment

[0026] Example 1

[0027] Cotton fabric 63"32*32 130*70 Twill tooling fabric with high light fastness navy blue reactive dye formula, including the following components by weight: Incai Clone Navy PL-N 43g / L, Incai Clone Crimson SF 7.2 g / L and Yingcai Clone Orange CD3.96g / L. The navy blue reactive dye is used to dye cotton fibers in the fabric, and the dyeing process includes fabric pretreatment, fabric dyeing, and fabric post-finishing. Dyeing includes the steps of pad dyeing, pre-drying, steaming, soaping, fixing and drying.

[0028] In this embodiment, the pre-treatment of the fabric includes desizing, scouring, oxygen bleaching, singeing and mercerizing, which are all performed according to the existing technology. In the pad dyeing and coloring step, the blended fabric is in the dye bath The relative moving speed of the intermediate dye bath is 50 yards / min, the temperature in the pre-drying step is 78°C, the temperature in the drying step is 90°C, and the temperature differe...

[0042] Example 3

[0043] Cotton 60%, polyester 40% fabric 63”20*16 128*60 3 / 1 tooling fabric high light fast navy blue reactive dye formula, the coloring step is to dye the polyester fiber with disperse dye first, and then use Reactive dyes dye cotton fibers to achieve the same two colors. The disperse dyes include the following components by weight: Yingcaixiu Navy Blue HSF-N14g / L, Yingcaixiu Yellow Brown HSF01 2.4g / L, British Caixiu Black HSF01 2.4g / L. The dyeing process includes fabric pre-treatment, fabric dyeing, and fabric post-finishing. The fabric dispersion dyeing includes pad dyeing, pre-drying, steaming, soaping, fixing and drying. Dry steps.

[0044] The reactive dye includes the following components by weight: Yingcai clone navy blue PL-N 24.5g / L, and Yingcai clone deep red SF 7.7g / L. The dyeing process successively includes the steps of pad dyeing, pre-drying, steaming, soaping, fixing and drying, so that the two colors are consistent.

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...
