Problems solved by technology

[0004] However, natural dyes are prone to poor color fastness and uneven dyeing in dyeing
In the prior art, the poor color fastness is usually improved by increasing the amount of dye, which will lead to high production cost and low utilization rate of dye

Embodiment 1

[0028] This embodiment includes the following steps:

[0029] (1) Extraction of vegetable dyes:

[0030] Extraction of plant pigments by ultrasonic method: First, the red vine is soaked in alcohol for 6 hours, the alcohol concentration is 50%, the extraction time is 40 minutes, and the ratio of solid to liquid is 1:12. Then put it into the ultrasonic wave, set the temperature at 50°C, the microwave power at 1000w, and the ultrasonic time at 20min, filter with an 80-mesh filter, put the filtrate in an oven at 150°C, and dry it for 12h to evaporate the water to obtain a concentrated solution . The vegetable dye raw material is red rattan.

[0031] (2) Synthesis of modifiers:

[0032] In a 500ml round-bottomed flask, add 5g of epichlorinated yeast derivatives of 2,3-epoxypropyltrimethylammonium chloride, then add 200ml of water, stir to dissolve, and add 1mol / l of Sodium hydroxide solution, after reacting for 5 hours, adjust the pH of the solution to 7 with 1.5 mol / l hydrochl...

Embodiment 2

[0039] This embodiment includes the following steps:

[0040] (1) Extraction of vegetable dyes:

[0041] Extraction of plant pigments by ultrasonic method: First, the red vine is soaked in alcohol for 7 hours, the alcohol concentration is 50%, the extraction time is 60 minutes, and the ratio of solid to liquid is 1:12. Then put it into the ultrasonic wave, set the temperature at 70°C, the microwave power at 1200w, and the ultrasonic time for 25min, filter with a 100-mesh filter, put the filtrate in an oven at 130°C, and dry it for 18h to evaporate the water to obtain a concentrated solution . The vegetable dye raw material is gardenia.

[0042] (2) Synthesis of modifiers:

[0043]In a 500ml round-bottomed flask, add 5g of epichlorinated yeast derivatives of 2,3-epoxypropyltrimethylammonium chloride, then add 200ml of water, stir to dissolve, and add 1mol / l of Sodium hydroxide solution, after reacting for 5 hours, adjust the pH of the solution to 7 with 1.5 mol / l hydrochlor...

Abstract

The invention relates to a method for dyeing a baby fabric by using a vegetable dye. The method comprises the following steps: (1) extracting a plant dye: extracting a plant pigment through an ultrasonic method, firstly soaking selected plant dye raw materials in alcohol for 6-8 hours, controlling the alcohol concentration to be 50%, controlling the extraction time to be 40-70 minutes, and controlling the material-liquid ratio to be 1: 12; the preparation method comprises the following steps of: putting the raw materials into ultrasonic waves, setting the temperature to be 50-80 DEG C, the microwave power to be 1000-1300w and the ultrasonic time to be 20-25min, filtering by adopting a 80-130-mesh filter screen, putting filtrate into a drying oven at the temperature of 100-150 DEG C, and drying for 12-24h, so that water is evaporated to obtain a concentrated solution; (2) synthesizing a modifier; and (3) dyeing the fabric with a vegetable dye.

Description

technical field [0001] The invention relates to a fabric, in particular discloses a method for dyeing baby fabrics with vegetable dyes. Background technique [0002] In recent years, the government and the public have continued to pay attention to environmental issues, and ecology, environmental protection, and sustainable development have become themes of social development. In environmental pollution, dyeing factories account for a large proportion. Due to the use of chemical dyes for dyeing, the pollution of the environment is serious. Natural dyes have the advantages of good compatibility with the ecological environment, biodegradability, low toxicity, and renewable raw materials, and the dyed fabric has natural color and fragrance. Some natural dyes also have antibacterial and anti-ultraviolet effects, which are not irritating to the skin. Small, ideal for dyeing fabrics for babies and toddlers. With the development of the national two-child policy, the society's dema...
