specific Embodiment 1

[0019] A method for dyeing dandelion fibers without dye, comprising the following steps: dipping—heating—washing, dehydration—drying—measuring the color fastness to washing;

[0020] In the soaking step: because the dandelion fiber is light and thin, and is wrapped with a layer of water-repellent substance, the dandelion is soaked in water at a temperature of 20° C. for 15 minutes before heating.

[0021] The water temperature is raised from 20°C to 50°C at a heating rate of 2°C / min, which takes 15 minutes and is kept at 50°C for 20 minutes to make the fiber gradually turn into ginger yellow.

[0022] In the washing and dehydration steps: wash with water at a normal temperature of 20° C. for 10 minutes, and then dehydrate.

[0023] In the drying step: the drying temperature is 70° C., and the drying temperature is 10 minutes.

[0024] In the step of measuring the color fastness to washing: the color fastness to washing is measured to be 3.5 grades.

specific Embodiment 2

[0026] A method for dyeing dandelion fibers without dye, comprising the following steps: dipping—heating—washing, dehydration—drying—measuring the color fastness to washing;

[0027] In the soaking step: because the dandelion fiber is light and fine, and is wrapped with a layer of water-repellent substance, the dandelion is soaked in water at a temperature of 30° C. for 20 minutes before heating.

[0028] The water temperature is raised from 30°C to 60°C at a heating rate of 1.5°C / min, which takes 20 minutes and is kept at 60°C for 30 minutes to make the fiber gradually turn into ginger yellow.

[0029] In the washing and dehydration steps: wash with water at a normal temperature of 30° C. for 15 minutes, and then dehydrate.

[0030] In the drying step: the drying temperature is 80° C., and the drying temperature is 15 minutes.

[0031] In the step of measuring the color fastness to washing: the color fastness to washing is measured to be grade 4.

specific Embodiment 3

[0033] A method for dyeing dandelion fibers without dye, comprising the following steps: dipping—heating—washing, dehydration—drying—measuring the color fastness to washing;

[0034] In the soaking step: because the dandelion fiber is light and fine, and is wrapped with a layer of water-repellent substance, the dandelion is soaked in water at a temperature of 24° C. for 18 minutes before heating.

[0035] The water temperature is raised from 24°C to 57°C at a heating rate of 1.9°C / min, which takes 17 minutes, and is kept at a temperature of 50°C-60°C for 26 minutes to make the fiber gradually turn into ginger.

[0036] In the washing and dehydration steps: wash with water at a normal temperature of 24° C. for 11 minutes, and then dehydrate.

[0037] In the drying step: the drying temperature is 73° C., and the drying temperature is 12 minutes.

[0038] In the step of measuring the color fastness to washing: the color fastness to washing is measured to be grade 4.

Abstract

The invention discloses a dandelion fiber non-dye dyeing method, which includes the steps of: dipping, heating, washing, dehydration, drying, and determination of colour fastness to washing. Specifically, in the heating step, the water temperature is raised from 20DEG C-30DEG C to 50DEG C-60DEG C at a rate of 1.5-2DEG C / min for 15-20min, heat preservation is conducted at 50DEG C-60DEG C for 20-30min to make fiber change into ginger colour gradually. The method provided by the invention has no need of adding any chemical dye, plant dye and assistant, fiber is processed to present ginger colour by itself so as to be comparable with natural colored cotton and natural colored silk. The method develops and utilizes novel pure natural yellow dandelion fiber material, makes waste profitable, and is low in processing cost. Being convenient to collect, the pure natural yellow dandelion fiber material also has the characteristics of pure naturalness, green, environmental protection, high water absorption and health care effect.

Description

technical field [0001] The invention belongs to the field of fiber fabrics, and in particular relates to a dye-free dyeing method for dandelion fibers. Background technique [0002] Dandelion's edible value, medicinal value, and nutritional value have been highly appraised and affirmed in "Compendium of Materia Medica", "Ci Hai" and ancient medical encyclopedias. Dandelion contains various nutrients such as dandelion alcohol, choline, organic acid, inulin, glucose, Vc, Vd, carotene, etc. It is also rich in trace elements, the most important of which is a large amount of iron, Ca, etc. needed by the human body. minerals. Its Ca content is 2.2 times that of guava and 3.2 times that of Rosa roxburghii, and its iron content is 4 times that of Rosa roxburghii and 3.5 times that of hawthorn. From the point of view of food nutrition, the inorganic elements most likely to be deficient in the human body are only Ca and iron. Therefore, dandelion has very important nutritional valu...
