[0019] A preparation method of American ginseng fruit vegetable dye is characterized in that it is prepared through the following steps:
[0020] (1) Raw material preparation: the American ginseng fruit collected is the fruit of American ginseng, rinsed with tap water, and drained naturally for extracting the dye solution;
[0021] (2) Preparation of American ginseng fruit vegetable dye: there are two preparation methods
[0022] Method (a) Direct crushing method for extracting juice:
[0023] Put the prepared American ginseng fruit into the existing crushing centrifugal juicer. After the machine is turned on, the mesh rotary cage with sawtooth on the chassis rotates at a high speed at a speed of 500-1500 rpm. At the same time, under the action of rotating centrifugal force, the liquid juice is released from the mesh of the rotating cage, collected in an external container, and then filtered through a 200-280 mesh fine-mesh screen for 1-3 times to prepare liquid American gins...
Embodiment 1
[0029] ① After the collected American ginseng fruit is washed with tap water, the water is naturally filtered out;
[0030] ②Using method (a), put the prepared American ginseng fruit into the crushing centrifugal juicer, and the rotary cage rotates at a high speed at a speed of 500 rpm. In the container, filter through a 200-mesh fine screen for 3 times to prepare liquid American ginseng fruit vegetable dye;
[0031] ③Carry out conventional dyeing process, under the condition of no mordant dyeing, use liquid American ginseng fruit vegetable dye to dye wool products, and purple wool products can be dyed.
Embodiment 2
[0033] ① After the collected American ginseng fruit is washed with tap water, the water is naturally filtered out;
[0034] ②Using method (a), the prepared American ginseng fruit is about to be put into a crushing centrifugal juicer, and the rotary cage rotates at a high speed at a speed of 1000 rpm. In the container, filter through a 240-mesh fine screen for 2 times to prepare the liquid American ginseng fruit vegetable dye, and deposit the American ginseng fruit vegetable dye with the bath ratio of 1:1 with the alcohol of 100% by the American ginseng fruit vegetable dye and the concentration of the American ginseng fruit vegetable dye. Store in a container of ethanol for later use;
[0035] ③ Carry out conventional dyeing processing, under the condition of metal aluminum ion mordant dyeing, use the above-mentioned liquid American ginseng fruit vegetable dye to dye wool products, and red wool products can be dyed.
