Embodiment 1

[0052] In the specific embodiment of the present application, the preparation method of each raw material component of the plant-based light fastness improving agent is as follows:

[0053] Scutellaria baicalensis extract is the water extract of Scutellaria baicalensis root; the mass ratio of Scutellaria baicalensis root to water is 1:10, the extraction temperature is 60°C; the extraction time is 2h; the extract is filtered, concentrated, separated, and dried to obtain a solid powder.

[0054] Turmeric extract is the water extract of turmeric rhizome. When extracting turmeric extract, the mass ratio of turmeric rhizome to water is 1:10, the extraction temperature is 60°C, the extraction time is 2h, and the extract is filtered, concentrated, separated and dried , to obtain solid powder.

[0055] Sophora japonica extract is the water extract of acacia flower. When extracting the extract, the mass ratio of acacia flower to water is 1:10, the extraction temperature is 65°C, the pH...

Embodiment 2

[0060] The raw material components in Example 1 were mixed according to the following proportions to prepare a plant-based light fastness improving agent:

[0061]

[0062] The plant-based light fastness improving agent in the present embodiment is used as improving the light fastness on textiles; Textiles are put into the padding tank that is filled with padding liquid with ultrasonic generator and carry out padding treatment; Padding After the treatment, the textile is steamed and dried; the ultrasonic frequency of the ultrasonic generator is 20kHz, and the ultrasonic time is 5min. During the padding treatment, one dipping and one rolling are adopted. The liquid carrying rate of the padding treatment is 50%, and the steam treatment time is 5min, the drying temperature is 100°C.

[0063] Wherein, the padding solution includes:

Abstract

A plant-based light fastness improving agent and its preparation method and application. The plant-based light fastness improving agent includes the following raw material components and parts by weight: 0.5-3 parts by weight of Scutellaria baicalensis extract, 1.5-3 parts by weight of turmeric extract 2 to 5 parts by weight of Sophora japonica extract, 2 to 10 parts by weight of mango leaf extract, 1 to 4 parts by weight of pineapple leaf extract, and 1 to 8 parts by weight of cactus extract; water extract; the turmeric extract is the water extract of turmeric rhizome; the Sophora japonica extract is the water extract of Acacia flower; the cactus extract is the water extract of cactus; the pineapple leaf extract is The acetone extract of pineapple leaves; the mango leaf extract is the extract of mango leaves in ethanol aqueous solution. The light fastness improving agent penetrates into the interior of the cotton fabric under the action of ultrasonic waves to obtain a fabric with good light fastness.

Description

technical field [0001] The invention relates to a light fastness improving agent applied to textiles, in particular to a plant-based light fastness improving agent and its preparation method and application. Background technique [0002] Vegetable dyes are the dyes with the longest and most widely used history among natural dyes, and are deeply loved by consumers. Due to the poor light fastness of plant dyes, their application range is limited. Most of the existing light fastness improving agents are chemically synthesized, which do not conform to the natural environmental protection concept of vegetable dyes, so it is imperative to develop green light fastness improving agents for textiles dyed with vegetable dyes. [0003] When exposed to sunlight, it is the main ultraviolet component that can damage dyes. After shielding ultraviolet rays, the light fastness of textiles will be greatly improved. The wavelength of ultraviolet electromagnetic waves is 100-400nm, which can b...
