Embodiment 1

[0011] A method for printing and dyeing textiles, comprising the steps of:

[0012] Put the natural fiber into a dye vat with a liquor ratio of 3:7, raise the water temperature to 75°C, add 10g / L ethyltriethoxysilane, 25g / L aluminum sulfate, 20g / L ferrous sulfate, and heat up To 94 ℃, keep warm for 2 hours to complete the ion modification of natural fibers;

[0013] Put the modified natural fiber into a dye vat with a bath ratio of 2:7. When the water temperature rises to 55°C, add 5g / L of triethanolamine, 30g / L of natural dye, and 10g / L of salt, and adjust the pH to 2.5, heat up to 65°C at a heating rate of 20°C / min, and keep it warm for 4 hours to complete the dyeing.

Embodiment 2

[0015] A method for printing and dyeing textiles, comprising the steps of:

[0016] Put the natural fiber into a dye vat with a bath ratio of 3:7, raise the water temperature to 65°C, add 5g / L ethyltriethoxysilane, 20g / L aluminum sulfate, and 15g / L ferrous sulfate, and heat up To 92 ℃, keep warm for 1 hour to complete the ion modification of natural fibers;

[0017] Put the modified natural fiber into a dye vat with a bath ratio of 2:7. When the water temperature rises to 50°C, add 5g / L of triethanolamine, 30g / L of natural dye, and 10g / L of salt, and adjust the pH to 2. Raise the temperature to 60°C at a heating rate of 15°C / min and keep it warm for 3 hours to complete the dyeing.

Embodiment 3

[0019] A method for printing and dyeing textiles, comprising the steps of:

[0020] Put the natural fiber into a dye vat with a bath ratio of 3:7, raise the water temperature to 68°C, add 7g / L ethyltriethoxysilane, 23g / L aluminum sulfate, and 18g / L ferrous sulfate, and heat up To 93 ℃, keep warm for 1.5 hours to complete the ion modification of natural fibers;

[0021] Put the modified natural fiber into a dye vat with a bath ratio of 2:7. When the water temperature rises to 52°C, add 5g / L of triethanolamine, 30g / L of natural dye, and 10g / L of salt, and adjust the pH to 2.3. Raise the temperature to 64°C at a heating rate of 18°C / min and keep it warm for 3.5 hours to complete the dyeing.

Abstract

The invention discloses a textile dyeing and printing method, which comprises the steps of: placing natural fiber in a dye vat with a bath ratio of 3:7, raising the water temperature to 65-75DEG C, adding 5-10g / L ethyl triethoxysilane, 20-25g / L aluminum sulfate and 15-20g / L of ferrous sulfate, raising the temperature to 92-94DEG C, and conducting heat preservation for 1-2 hours to complete modification of natural fiber ions; putting the modified natural fiber into a dye vat with a bath ratio of 2:7, raising the water temperature to 50-55DEG C, adding 5g / L triethanolamine, 30g / L of a natural dye and 10g / L of a salt, adjusting the PH to 2-2.5, raising the temperature to 60-65DEG C at a rate of 15-20DEG C / min, and performing heat preservation for 3-4 hours, thus completing dyeing. The textile printed and dyed by the method provided by the invention has the advantages of environmental protection, uniform dyeing, and color fastness.

Description

technical field [0001] The invention relates to a textile printing and dyeing method. Background technique [0002] The use of natural dyes to dye textiles requires multiple use of modifiers and dyeing aids. The process is complicated and the cost is high. Most of the modifiers contain heavy metals, which are harmful to the human body and the dyeing effect is not good. Discoloration, uneven dyeing. Contents of the invention [0003] The purpose of the present invention is to provide a textile printing and dyeing method, the textiles printed and dyed are environmentally friendly, and the dyeing is even and does not fade. [0004] In order to achieve the above object, the technical solution of the present invention is to design a textile printing and dyeing method, comprising the steps of: [0005] Put the natural fiber into the dye vat with a liquor ratio of 3:7, raise the water temperature to 65-75°C, add 5-10g / L ethyltriethoxysilane, 20-25g / L aluminum sulfate, 15-20g / ...
