Recognizing vegetable dyes
The method is based on natural vegetable dyes, dye roots, stems, leaves, flowers, fruits, dry wood extraction plant sap as a dye to dye linen, silk, wool, cotton and other natural fibers. (Chen Qianhui, 2002) Traditional Hakka area of a blue dye is vegetable dyes, vegetable dyes and the relationship of human life is quite close, many ethnic groups have their own dyeing techniques and materials, generally as vegetable dyes to dye materials are terrestrial plants based.
Classification of vegetable dyes
Vegetable dyes can be classified according to the temperature of the thermal dye stain with cold dye (blue dye, persimmon dyeing, dyeing Shulang) categories
Thermal dye categories: Most plants can make pigment extracted heat, thermal dye. Stained wood processing: collected peel or branches leaves clean, must be cut into pieces, allowing easier extraction of pigment. Stained timber, add water and cook for 30 minutes after boiling, you can filter dye impurities, plus boiled water again and the second dye extracted twice by adding dye into the dye pot.
Cold dye categories: persimmon dyeing, green persimmon contains a lot of tannin, can be used in everyday life as a folk medicine and dyeing, the persimmon juice also has a lot of gum, can strengthen and increase the strength of the fabric waterproof features, but also with anti- insects, mildew effect. Health persimmon juice dyeing process without heating, simply soaked pollutants placed in the hot sun, you can get natural color, energy saving and care. Shulang dye: Shulang is a perennial twining vine, rich tannins and gum, can be dyed red ocher and black paint, a large number of Han Chinese and indigenous people are using, in addition to a large number of Ranyi dyed yarns are dyed nets, because Shulang dyed fibers can enhance resilience and prevent seawater corrosion. Aizen: Aizen broadly refers to the use of blue dye staining techniques. A narrow blue dye refers to the use of natural indigo dyeing techniques performed.

Step vegetable dyes
Thermal dye dyeing steps: (1) the collection of dye (2) chopping stained wood (3) extraction of dye (4) filter dye (5) pollutants banding pattern (6) pollutants soaking water. (7) After pollutants into the dye and cook 20 minutes after transfection, picked wrung. (8) into the media dye soak for 20 minutes, and picked up wring. (9) again pollutants into the dye and cook 20 minutes after transfection, picked wrung. (10) flush. (11) dry complete.
Blue dye dyeing steps: (1) the dyed soaked (2) wring (3) disseminated <3 to 15 minutes each time, the number of multi-color depth> (4) Oxidation
Vegetable dyes and the effect of tying law introduced
| Dyeing bundle type | Tied law introduced | Pictorial effect |
| Tie dye cloud | 1.Would want to stain the white cotton, casual crumpled. 2.Reuse coarse thread, from the inside out, from tight to loose wrap around it. As the dye will penetrate between the color density cotton, because there is no certain norms, so each finished will show different results are due to the shape of clouds in the blue sky, hence the term cloud dye. |

| Clip tie dye | 1. Would be on the cloth, fold down, then left and right fold. 2. Repeat(1)of practice, into a small square. 3.Take a splint, in any corner of the small square, will be arranged in the middle of plywood, plywood sides with a line tied on. Whichever is diagonal, repeat (3) of the practice. |

| Dougan tied | 1. Smoothing the cloth, fold, then folded into a long strip. 2.Then (1) long strip folded around by the end of the cloth to the center of each opening being folded into a square. 3.Would be (2) of the graphics, the upper and lower ends of wire wound three times to kill tied knot, and then cut the excess wire. Then by the left and right ends of wire wound three times to kill tied knot, and then cut the excess wire. 4.Take a long strip of the center, tied three times taut, killing knot, cut the excess wire. To (4) of the center of the main tied to the spacing of 1 to 2 cm, left and right sides of the cloth tied up before the end point at one centimeter. |
|
| Linear tied | 1.Smoothing the cloth, up, down, left, right, folded into a square. 2.Would be aligned with the center of their own, folded up a triangle. 3.From 1cm spacing with a tip of the triangle to the next flip folded into a long strip. |

| Lu-Key tied | 1.Smoothing the cloth, up, down, left, right fold, into a square. 2. Placed in the center of the fabric of the right-hand side, Serve a positive diamond. 3.from bottom to top on the cloth folded into a triangle. 4. to one centimeter spacing to the tip of the triangle, the next flip folded into a long strip. 5.would prevail on the graphic to the center, on the right at the wound three times a centimeter taut, then oblique way around, Raozhi the left one centimeter at the center, and then after three laps around a taut, ramp around the back end of a thread tied, cut the excess wire. 6.to (5) of the pattern end of the cloth down in two overlapping alignment. In the end two centimeters for the center, according to the former step (5) of the Act tied tied once again, you can. |
