Problems solved by technology

[0002] Natural isatis root, horse indigo, indigo indigo, wood indigo and other fermented and extracted plant dyes are commonly used in dyeing dark fabrics and clothing, with poor soaping fastness and wet and dry rubbing color fastness.
The conventional process is to use chemical soaping agent to wash with water for many times, and more to do sand washing for clothing. Both methods will generate a large amount of sewage and cause environmental pollution.

Embodiment 1

[0027] The ultrasonic circulation soaping method that is used for Radix Radix Radix Vegetable Dye dyeing comprises the following steps:

[0028] 1) Add 40kHz ultrasonic waves to the stainless steel soaping equipment made of SUS304 or SUS306, and the ultrasonic intensity is 0.8W / cm 2 . Bath ratio 1:30 (relative to the weight of the fabric and clothing) is added to tap water or demineralized water, and ozone is introduced at the same time. The dosage of ozone is 1mg / L. The dyeing solution uses Radix isatidis vegetable dye.

[0029] 2) Add 0.5g / L hydrogen peroxide to the aqueous solution, add 1g / L natural soaping agent HO, and turn on the ultrasonic wave and ozone generator at the same time Soap at 20°C for 10 minutes;

[0030] 3) Fabrics and garments dyed with Radix isatidis plant dyes are subjected to enhanced micro-nano ozone ultrasonic soaping, and the soaping solution can be recycled. Each time, add clean water to the liquid level, add 0.5g / L of hydrogen peroxide, and add ...

Embodiment 2

[0034] The ultrasonic circulation soaping method that is used for Radix Radix Radix Vegetable Dye dyeing comprises the following steps:

[0035] 1) Add 40kHz ultrasonic waves to the stainless steel soaping equipment made of SUS304 or SUS306, and the ultrasonic intensity is 1.5W / cm 2 . Liquor ratio 1:30 (to the weight of fabrics and clothing), add tap water or demineralized water, and pass in ozone at the same time, and the dosage of ozone is 1.5mg / L;

[0036] 2) Add 1g / L hydrogen peroxide to the aqueous solution before putting the fabrics and clothes dyed with isatidis plant dye into the ozone ultrasonic soaping equipment, and turn on the ultrasonic wave and ozone generator at the same time, and soap them at 20°C for 10 minutes

[0037] 3) Fabrics and clothing dyed with Radix isatidis plant dyes are subjected to enhanced micro-nano ozone ultrasonic soaping, and the soaping solution can be recycled. Each time, add clean water to the liquid level, add hydrogen peroxide 1g / L, an...

Embodiment 3

[0041] The ultrasonic circulation soaping method that is used for Radix Radix Radix Vegetable Dye dyeing comprises the following steps:

[0042] 1) Add 40kHz ultrasonic waves to the stainless steel soaping equipment made of SUS304 or SUS306, and the ultrasonic intensity is 1.2W / cm 2 . Liquor ratio 1:30 (to the weight of fabrics and clothing), add tap water or demineralized water, and pass in ozone at the same time, and the dosage of ozone is 1mg / L;

[0043] 2) Add 1g / L hydrogen peroxide to the aqueous solution, add 0.5g / L natural soaping agent HO, and turn on the ultrasonic wave and ozone generator at the same time Soap at 20°C for 10 minutes

[0044] 3) Fabrics and garments dyed with Radix isatidis plant dyes are subjected to enhanced micro-nano ozone ultrasonic soaping, and the soaping solution can be recycled. Add clean water to the liquid level each time, add hydrogen peroxide 1g / L, and add 0.2g / L natural soaping agent HO.

Abstract

The invention relates to an ultrasonic circulating soaping method used for dyeing by adopting isatis root plant dye. In soaping equipment, ultrasonic waves are adopted, and ozone is introduced; beforefabrics and clothes which are dyed by the isatis root plant dye are put in the soaping equipment, hydrogen peroxide is added into an aqueous solution, and a natural soaping agent HO is added for soaping for 2-20 minutes; a soaping solution is recyclied, and hydrogen peroxide and a natural soaping agent HO are supplemented. The method has the advantages that surface dyeing of dyed textile by adopting the plant dye can be greatly removed, all plant pigments are thoroughly oxidized, parts of water-soluble pigments can be degraded and mineralized, the soaping fastness of the textile dyed by the isatis root plant dye is improved to reach 1-2 grade, and the dry-wet color fastness to rubbing is improved to above 1 grade.

Description

technical field [0001] The invention belongs to the field of dyeing of isatidis plant dyes, and in particular relates to an intensified micro-nano ozone ultrasonic cycle soaping method for dyeing of isatid root plant dyes. Background technique [0002] Natural isatis root, horse indigo, indigo indigo, wood indigo and other fermented and extracted vegetable dyes are generally poor in soaping fastness and dry and wet rubbing color fastness when dyeing dark fabrics and clothing. The conventional process is to use chemical soaping agent to wash with water for many times, and more to do sand washing for clothing. Both methods will generate a large amount of sewage and cause environmental pollution. [0003] In order to reflect the environmental protection properties of natural plant dyes, it is best to achieve zero drainage in the entire production process. To this end, the enhanced micro-nano ozone ultrasonic cycle soaping method with natural soaping agent and a small amount of...
