AI Technical Summary

Benefits of technology

This patented technology describes different methods that make it easier than traditional ways to create blueprints on paper without causing environmental damage. It also includes extraction with limewater followed by centrifuge processing steps like precipitation and separation techniques to obtain pure colors from crude oil residue. Additionally, this new technique allows for easy addition of other ingredients such as pigments into the mixture beforehand making sure they don't affect its quality. Overall, these technical improvements help reduce costs associated with producing blueprinted objects.

Problems solved by technology

This patented technical problem addressed by this patents relates to finding an alternative material without containing harmful components during fabric dying and detergent-making procedures while still having good properties when applied at home instead of being developed based solely upon chemistry methods like synthesis dyes.

Embodiment 1

[0027] A process for quickly extracting pigments from plants to prepare dyes comprises the following steps.

[0028] 1) Mashing: Wash the whole plant including the flower part and put it into a masher to mash.

[0029] 2) Mixing: Mix water and crushed plant fragments at a ratio of 1:4 by mass, then pour into a blender and stir for 5 minutes to obtain a mixed solution. The speed of the blender is 30r / min.

[0030] 3) Cooking: heat the mixture to 80°C for 15 minutes.

[0031] 4) Filtration: Ultrafiltration removes impurities from the cooked mixture to obtain filtrate and filter residue.

[0032] 5) Layering: Add Ca(OH) to the filtrate 2 The solution was left to stand for 1.5 hours and then poured into a centrifuge for centrifugation to obtain a layered liquid, and then the different colored layers were extracted to obtain dye solutions of various colors. Among them, Ca(OH) 2 The solution consists of Ca(OH) 2 It is formulated with water at a mass ratio of 1:1, Ca(OH) 2 The ...

Abstract

The invention discloses a technology for rapidly extracting pigment from plants for preparing dyes. The technology is characterized by comprising the following steps of 1, smashing, 2, mixing, 3, cooking, 4, filtering, 5, layering, 6, concentration, 7, drying and 8, smashing. The technology has the advantages that adopted raw materials and an additive contain no hazardous substances and will not pollute the environment, only one additive is added, the technological difficulty is greatly lowered, and the requirement for safe and environment-friendly production is met. Due to the fact that lime water is added, centrifugal treatment is performed to enable a mixing solution to be layered, and a colored layer is extracted as a dye solution; the sources of the lime water are wide, the price is low, and therefore the preparation cost is lowered. The raw materials needed for preparing the dyes are common, single-color and rich plant petals, the plant petals can be obtained through large-area planting and can also be obtained by purchasing from farmer households, sources are wide, and the phenomenon that production cannot be performed due to raw material lack is avoided.
