Formula and production method for preparing brown wheat straw dye

Abstract

The invention relates to a formula and a production method for preparing brown wheat straw dye. The formula is characterized by adopting dry hibiscus mutabilis, isatis tinctoria, alumen, areca-nut, an iron-ion compound solution and mineral water as main raw materials. The production method comprises the following main steps of sorting, cutting, drying, soaking, boiling, mixing, precipitating, dying and forming a finished product. The invention relates to the formula and the production method for preparing the brown wheat straw dye which is pure natural, pollution-free, environment-friendly and free from toxic and side effects on the human body and prepared by from the pure natural plants.

Description

Technical field:

[0001] The invention relates to a plant dye, in particular to a formula and production method for preparing brown wheat straw dye Background technique:

[0002] In the prior art, there are many ways to dye wheat straw, the main raw material for making wheat straw paintings, into brown, but most of the dyes are chemical dyes, and the dyed brown color is not pure and easy to fade. The process will even produce toxic gas, which threatens human health.

[0003] Therefore, there is a lack of a plant dye that can dye wheat straw into different colors in the field of wheat straw painting, especially a pure natural vegetable dye that can dye wheat straw into brown. The brown wheat straw dyed by it is not only pure in color, but also made of its material The wheat straw paintings produced are bright and bright, not easy to fade, and are green and environmentally friendly. The works emit a plant fragrance for a long time, which can improve people's physical and men...

Examples

Embodiment 1

[0015] The formula weight ratio range for preparing the brown wheat straw dye of the present invention is: 10-30 parts of dried hibiscus flower, 10-30 parts of woad indigo, 10-30 parts of alum, 10-30 parts of betel nut, and 5-15 parts of iron ion compound solution , 30-80 parts of mineral water.

Embodiment 2

[0017] The preferred weight ratio range of the formula for preparing the brown wheat straw dye of the present invention is: 10-25 parts of dried hibiscus flower, 10-25 parts of woad indigo, 10-25 parts of alum, 10-25 parts of betel nut, 5-13 parts of iron ion compound solution 30-70 parts of mineral water.

Embodiment 3

[0019] The optimal weight ratio range of the formula for preparing the brown wheat straw dye of the present invention is: 15 parts of dried hibiscus flower, 15 parts of woad indigo, 15 parts of alum, 15 parts of betel nut, 15 parts of zhehuang, 7 parts of iron ion compound solution, mineral water 60 servings.

[0020] The above-mentioned components are prepared into the production method of brown wheat straw dyestuff of the present invention. The main technological process is: material selection, material cutting, drying, soaking, boiling, mixing, precipitation, dyeing, and finished product. The specific operation method is as follows: Steps: A, material selection, according to the weight ratio of raw materials, select dried hibiscus flower, woad indigo, alum, betel nut, iron ion compound solution, mineral water that meet the national hygiene and quality standards for subsequent use; B, cutting materials, the selected The raw materials are cut into blocks respectively; C, ...
