Zaran is an ancient tie-dyeing process in China with a long history and is an intangible cultural heritage of China. The tie-dyeing process is simple and varied and has been loved by people. Even so, traditional techniques like tie-dye have come to an end in the wake of material civilization. Fortunately, Tie-dye finally survived a difficult period and began to develop in a good direction after incorporating some new elements. Let me introduce the basic way of tie dyeing.
First, the pretreatment of tie dyeing
1. Desizing: The purpose is to remove the slurry and use the lye, oxidant or amylase to add boiling water to boil the cloth. Dosage: The agent is 3% of the cloth weight, and the water is about 30 times the weight of the cloth.
2, refining: the purpose is to go out on the fiber of the natural magazine and residual slurry, and boiled with caustic soda. Dosage: caustic soda is 3% of the weight of the cloth, and water is about 30 times the weight of the cloth.
3, bleaching: used to get out the pigment and residual impurities, commonly used sodium hypochlorite or hydrogen peroxide plus water boil. Dosage: The bleaching agent is 3% of the cloth weight, and the water is about 30 times the weight of the cloth. In addition, the pretreatment of the silk is refined by adding soap and sodium carbonate plus water.
4. Ironing and standby: Ironing the rinsed cloth with iron for drawing patterns and strapping.
Second, the tie-up technique
1. Bundling method: The bundling method is to bind the fabric according to the pre-conceived idea, or to pick up a little, or to grow a strip, or to do various folding treatments, and then use cotton or hemp rope to bind.
2. Folding method: It is the most widely used technique in tie dyeing. It is an asymmetrical single pattern after dyeing the folded fabric; it can be made into two continuous patterns after folding one by one.
3, flat stitch sewing method: flat stitch sewing method can form the current pattern, can form stripes, can make flower shape, leaf shape. The needle is threaded, and the designed pattern is evenly sewed on the fabric and then tightened. This is a convenient and free way to fully express the designer's creative intent.
4, the needle stitching method: the needle stitch of the needle and the cloth can be used to obtain a dotted pattern.
5, the method of ligation: the ligation method is to diagonally fold the fabric, fold it in different ways, and then tie it tightly to produce a function of blocking the penetration of the dye solution. The knotting methods are four-corner knotting, oblique knotting, knotting of any part, and the like.
6. The method of clamping: using a circular, triangular, hexagonal shape of wood, bamboo, bamboo sticks to clamp the folded fabric, and then tied with a rope to form a dye-proof, the fabric between the splints produces a hard straight" Compared with the stacking method, the black and white effect is more distinct and has a rich color halo.
7. Folding line clamping method: fold the fabric with the screen wind, and use the strip-shaped wooden board to clamp the two ends of the wooden board, which can be made into a continuous pattern.
8. Bean seeds: Put the tie-dyed fabric into small objects such as beans, coins or pebbles that will not be dyed or destroyed, and then tie them like a free tower.
9, the total tie method: the combination of strapping, tying, twisting and plywood and other techniques, different combinations can get rich and colorful effects.
