Embodiment 1

[0034] Biomido auxiliary formula is as follows (% by weight):

[0035] Chitosan 1%

[0036] 0.12% of acetic acid

[0037] Tea polyphenol 0.3%

[0038] 1% of sodium sulfate / water sodium sulfate (mass ratio 3: 1)

[0039] The remaining amount is deionized water.

[0040] The biological auxiliary method is as follows:

[0041] Step (1): Accurately weigh a certain amount of chitosan, and a solution containing 1% solids with a deionized water of 50 ° C;

[0042] Step (2): 0.12% of the acetic acid was added to the chitosan solution in step 1 to promote the dissolution of the chitosan solution and the viscosity was 12 MPa.s.

[0043] Step (3): 0.3% of the tea polyphenols, and 1% after potassium sulfate / sodium chloride were added to the magnetic stirrer and stir well.

Embodiment 2

[0070] Biomass Auxiliary Auxiliary Anti-Embodiment 1, distinguishing between: Adjusting the proportion of the chitosan in the biomido auxiliary agent, as shown in Table 2, using the method of applying Example 1 to staining cotton / Hyr blend fabric, The effects of chitosan content on fabric dyeing effects were studied. According to national standards GB31701-2015, the color fastness, k / s value, etc. were detected, and Table 2 was obtained.

[0071] Table 2, the effect of chitosan on dyeing effect

[0072]

[0073] Table 2 Analysis: According to Table 2, as the chitosan content increases from 1% to 6%, the K / S value of the fabric follows it; and the resistance of resistance is less than 2% in the chitosan content of less than 2%. When the performance is good, more than 2%, the decline will be decreased; the fastness of the sweat, especially when the anti-sweet acid alkali discoloration is more than 2%, the color difference is obvious; when the chitosan content is less than 2%...

Embodiment 3

[0075] Biomass Auxiliary Anti-Bioplasmic Auxiliary Auxiliary Example 1 differs to: Adjusting organic acid and its proportion in the biomidic aid, as shown in Table 3, using the method of applying Example 1 to staining cotton / Hyr blend fabric, The effects of organic acid content on the dyeing effect of fabric were studied. According to national standards GB31701-2015, it was detected from color fastness, k / s value, and the like, respectively.

[0076] Table 3, the choice of organic acid and the effect of content on dyeing effect

[0077]

[0078]

[0079] Table 3 Analysis: It is known from Table 3, and Example 1 is a preferred process, and the control is performed with Examples 2-1 to 2-4. As the acetic acid content is increased, the K / S value of the fabric is elevated, the fabric The fast-resistant fastness is improved with the increase of the acetic acid content, gradually increases, the weakness of the fabric is near the 3 stage, and the change is not obvious. After re...

Abstract

The invention discloses a biomass assistant as well as a preparation method and application thereof. The biomass assistant is characterized by comprising the following components in percentage by weight of 1%-5% of chitosan, 0.1%-0.3% of organic acid, 0.2-0.5% of tannic acid, 1%-3% of inorganic salt, and the balance of deionized water. The biomass assistant prepared by the method is applied to a vegetable dye dyeing process for a cellulosic fiber fabric, and can improve the problem of poor color fastness of vegetable dye; and compared with a traditional vegetable dye dyeing process, by combining with the chemical characteristics of sappan wood and madder dyes and taking the biomass assistant as a medium, the dye, the assistant and the fiber are ingeniously and organically combined, so that not only is the color fastness improved, but also the necessary dyeing assistant is saved and the environmental pollution is reduced in the dyeing process.

Description

Technical field [0001] The present application relates to a biomassotent and preparation method and application thereof, specific in the field of dyeing aid. Background technique [0002] In recent years, as consumers have gradually improved the ecological environment and their own health, environmentally friendly, non-toxic, harmless biomass products enters people's field of vision, such as natural pigments extracted from plants or animals. Synthetic dyes. For dyeing of the fabric, or use an ecological environmental protection aid during the dyeing process. It has always been, and the plant dyes have low color fastness of the dyeing fabric, and the reproducibility difference is not possible to further restrict the development. In view of this, the present application provides a path to plant dyes, especially routine red-based plant dyes, such as vest, Suhu, etc., which provides a way to improve the quality of red-colored plant dyes. Most of the pigment contained in the plant dye...
