Embodiment 1

[0051] 1) Before dyeing, according to figure 1 The schematic diagram of the vat washing process curve is shown, the bath ratio is controlled to 1:8, and the degreaser and soda ash are added to the main tank from the auxiliary vat according to the cleaning solution containing 0.5g / L of degreaser and 0.5g / L of soda ash. After the vat, quickly raise the temperature to 72°C and keep it warm for 5 minutes, then raise the temperature to 90°C at a heating rate of 2°C / min, keep it warm for 25 minutes, then cool down to 80°C to drain the liquid, then wash the dyeing vat with clean water for 10 minutes once, and drain the liquid.

[0052] 2) Put the knitted fabric in a clean dye vat for pre-treatment scouring, dyeing and post-treatment soaping to obtain semi-finished dyed fabric.

[0053] 3) After soaping, follow figure 2 The schematic diagram of the over-softening and color-fixing process curve is shown, the bath ratio is controlled at 1:6, and the required acetic acid is added from ...

Embodiment 2

[0056] 1) Before dyeing, according to figure 1 The schematic diagram of the cleaning process curve shown in the figure shows that the bath ratio is controlled to be 1:9, and the cleaning solution contains 1.2g / L of degreaser and 1.2g / L of soda ash, and the required degreaser and soda ash are added from the auxiliary tank to the main tank After the vat, quickly raise the temperature to 75°C and keep it warm for 5 minutes, then raise the temperature to 95°C at a heating rate of 5°C / min, keep it warm for 20 minutes, then cool down to 85°C to drain the liquid, and then wash the dyeing vat with clean water for 10 minutes, once, and drain the liquid.

[0057] 2) Put the knitted fabric in a clean dye vat for pre-treatment scouring, dyeing and post-treatment soaping to obtain semi-finished dyed fabric.

[0058] 3) After soaping, follow figure 2 The schematic diagram of the over-softening and color-fixing process curve is shown, the bath ratio is controlled to 1:7, and the pH of the ...

Embodiment 3

[0061] 1) Before dyeing, according to figure 1 The schematic diagram of the cleaning process curve shown in the tank, the bath ratio is controlled at 1:10, according to the cleaning solution containing 2g / L of degreaser and 2g / L of soda ash, add the required degreaser and soda ash from the auxiliary tank to the main tank , quickly raise the temperature to 78°C and keep it for 10 minutes, then raise the temperature to 95°C at a heating rate of 5°C / min, keep it for 15 minutes, then cool down to 85°C to drain the liquid, then wash the dyeing vat with water for 10 minutes, once, and drain the liquid.

[0062] 2) Put the knitted fabric in a clean dye vat for pre-treatment scouring, dyeing and post-treatment soaping to obtain semi-finished dyed fabric.

[0063] 3) After soaping, follow figure 2 The schematic diagram of the oversoftening and color fixing process curve is shown, the bath ratio is controlled to 1:8, and the pH of the solution is adjusted to 5-6. First, the required a...

Abstract

The invention discloses a fabric dyeing method. The method comprises the following steps: placing a fabric in a dye vat for dyeing to obtain a semi-finished yarn dyed fabric; placing the semi-finishedyarn dyed fabric into an acetic acid solution being 5 to 6 in pH, preserving heat at the temperature of 42 to 48 DEG C for 5 to 15 minutes, then adding a softener and continually preserving heat for5 to 15 minutes; adding a hydrophilic fixing agent, continually preserving heat for 10 to 20 minutes, discharging and drying to obtain the yarn dyed fabric. By adopting the method, the hydrophilicityof the yarn dyed fabric can be remarkably improved, and the hydrophilicity percent of pass of the obtained yarn dyed fabric is 97 percent or more.

Description

technical field [0001] The invention relates to the technical field of fabric dyeing production, in particular to a fabric dyeing method and colored fabrics. Background technique [0002] In the dyeing production process and functional finishing of knitted fabrics, knitted fabrics are required to have good permeability and hydrophilicity, so that chemical materials can be attached to the fabrics through the medium, and dyeing and functional finishing can be completed, thus improving the quality of fabrics. The hydrophilic effect is very important. [0003] At present, there are two main types of research on improving the hydrophilic properties of knitted fabrics: one is physical methods: improving the hydrophilicity of fibers by blending with hydrophilic substances or composite spinning, or performing microporous treatment of fibers and shaping fiber cross-sections. The second is the chemical method: through the introduction of hydrophilic monomer block copolymerization to ...
