Different from the mass production of traditional printing and dyeing industry, special dyeing process refers to the dyeing of single style, garment piece or batch ready to wear. Common special dyeing processes include modern tie dyeing, such as clip dyeing, hanging dyeing, cold dyeing (also known as dirty dyeing), injection dyeing, discharge dyeing and batik dyeing. With a sense of freehand brushwork, natural handedness and freedom of randomness, they are widely used. From traditional Chinese folk clothing to European and American leisure fast selling brand clothing, from street trendy hippies to star high order dresses, special dyeing processes have always been regarded as an important expression of artistic fashion
