Embodiment 1

[0025] A method for extracting rosewood reddish-brown plant dye, comprising the steps of:

[0026] Step 1, pulverization: take 1 kg of small-leaf rosewood, and pulverize it into wood powder with a pulverizer;

[0027] Step 2, steam flour: steam the wood flour in a high-energy steamer at 450°C for 30 minutes to soften the wood flour;

[0028] Step 3, separation: put the softened wood powder into a 200-mesh stainless steel mesh bag immediately, put it into 2kg of water at 100°C, add 10g of ethanol, and use a 350MHz ultrasonic box to separate for 30min;

[0029] Step 4, color fixation: After observing the color of the water from light to dark, pick up the net bag, add 40g of resin glue, and keep boiling at 100°C for 20 minutes to obtain a red ecological plant liquid dye;

[0030] Step 5, solid state: the red ecological plant liquid dye obtained in step 4 is press-filtered with a 400-mesh plate frame until the water content is 20%, and then baked with a steam dryer with a baking ...

Abstract

The invention discloses a rosewood reddish brown plant dye extraction method which includes the steps: crushing pterocarpus santalinus into wood powder by a crusher; steaming the powder by a high-energy steam box; adding softened wood powder into water and ethyl alcohol, dissolving the wood powder and separating by an ultrasonic box; adding resin adhesives into solution after standing and filtering, and fixing colors by boiling of water to obtain red ecological plant liquid dyes; finally, filter-pressing the dyes by a plate-and-frame filter press and baking the dyes into solids by a steam baking machine. According to the rosewood reddish brown plant dye extraction method, the quantity of dry powder of the red dyes is five to ten percent of the weight of the wood, the plant dyes extracted from the pterocarpus santalinus are quite high in red pigment content, coloring dosage can be decreased, and the colorability of the plant dyes is better than that of common plant dyes. Besides, by theaid of baking time of a dryer, the plant dyes can be finally baked into the dry powder and can also become dye liquid or solid dyes, and production is performed as required.

Description
