Problems solved by technology

[0002] The pad dyeing process in the traditional dyeing method is to chemicalize the material at 70-90°C, filter it and transfer it to a stainless steel vat, and then carry out cloth feeding→rolling material→pre-baking→pre-baking→drying cylinder→cradle car→pad color fixing→ Steaming→cold water washing→cold water washing→soaping→soap washing→cold water washing→drying drum→cloth output, the above process contains 4 cold water, 4 hot water and then drying, the process is long, energy consumption is large, and the dye is only Adsorbed on the surface of the fabric, it is easy to produce color difference between the side and the front and back during the pre-drying and steaming process, and the waste of water, electricity and steam is large

Embodiment 1

[0024] Example 1 4.0×4.0 / 133×72

[0025] A high-efficiency and energy-saving dyeing process, said process comprising the steps of:

[0026] (1) Pre-treatment, singeing → desizing → oxygen bleaching → mercerizing of the fabric;

[0027] (2) Dyeing, the fabric is placed on the cold pad-batch dyeing equipment for cloth feeding→rolling→rolling;

[0028] (3) Stacking, placing the fabric dyed in step (2) at a temperature of 45°C and a humidity of 30% in a factory shed for 8-10 hours;

[0029] (4) Water washing, put the fabric treated in step (3) in 2 cold water washes, 3 hot water washes and then dry, that is, wash in cold water at room temperature → cold water at room temperature → wash in hot water at 95±2°C → 95±2°C Washing in hot water→washing in hot water at 95±2℃→drying;

[0030] (5) Weft adjustment, stretching, pre-shrinking.

[0031] Dyestuffs used for dyeing in the described step (2) include: Ciba G black 45g / L, Ciba S-4R orange 4g / L, Ciba S-D red 5g / L, chelating disper...

Embodiment 2

[0039] Example 2 60×60 / 90×88

[0040] A high-efficiency and energy-saving dyeing process, said process comprising the steps of:

[0041] (1) Pre-treatment, singeing → desizing → oxygen bleaching → mercerizing of the fabric;

[0042] (2) Dyeing, the fabric is placed on the cold pad-batch dyeing equipment for cloth feeding→rolling→rolling;

[0043] (3) Stacking, placing the fabric dyed in step (2) at a temperature of 30°C and a humidity of 35% in a factory shed for 8-10 hours;

[0044] (4) Water washing, put the fabric treated in step (3) in 2 cold water washes, 3 hot water washes and then dry, that is, wash in cold water at room temperature → cold water at room temperature → wash in hot water at 95±2°C → 95±2°C Washing in hot water→washing in hot water at 95±2℃→drying;

[0045] (5) Weft adjustment, stretching, pre-shrinking. The performance test results of the obtained fabrics are shown in Table 1.

Abstract

The invention discloses an energy-efficient dyeing technique. The technique comprises the following steps: (1) pretreatment; (2) dyeing; (3) stacking; (4) water washing; and (5) weft straightening, stentering and preshrinking. The dyeing technique has the characteristics of short dyeing process and step saving, improves the chromatic aberration and the color shading of the side and center before and after, and greatly enhances the water washing effect of fabrics (more obvious for deep color series).

Description

technical field [0001] The invention relates to the technical field of printing and dyeing, in particular to a dyeing process that reduces energy consumption by saving procedures. Background technique [0002] The pad dyeing process in the traditional dyeing method is to chemicalize the material at 70-90°C, filter it and transfer it to a stainless steel vat, and then carry out cloth feeding→rolling material→pre-baking→pre-baking→drying cylinder→cradle car→pad color fixing→ Steaming→cold water washing→cold water washing→soaping→soap washing→cold water washing→drying drum→cloth output, the above process contains 4 cold water, 4 hot water and then drying, the process is long, energy consumption is large, and the dye is only Adsorbed on the surface of the fabric, it is easy to produce color difference between the side and the front and back during the pre-drying and steaming process, and the waste of water, electricity and steam is large. [0003] In the general dyeing process,...
