Of textile materials (fibers, yarns and fabrics) for the chemical treatment process-oriented. Finishing with the spinning, weaving or knitting production together to form the whole process of textile production. Dyeing and finishing, including pretreatment, dyeing, printing and finishing. The merits of the quality of the textile dyeing and finishing of the use value has important implications. Pretreatment also known as bleaching, and its main purpose is to remove the impurities of textile materials, so that subsequent dyeing, printing, finishing smooth to obtain the desired processing results. Dye and fiber staining is occurring through physical or chemical combination of textile materials, leaving a certain color. Printing paste is used to obtain color on the textile patterns. The role of sorting through the physical or chemical agents to improve the luster of the fabric, shape and other appearance; to improve the performance of fabric or the fabric with water repellent, oil resisting properties. Most of the finishing post in the fabric dyeing and finishing stages. In wool fabric dyeing and finishing processes are often classified into many pre-sorting area, and to organize into wet finishing and dry finishing.

Dyeing and finishing is generally conducted in single stage. In accordance with the process requirements, and some stand-alone coalition can be connected sequentially continuous production machine. The combined machine is a common padding, steaming, washing, drying and other equipment consisting of, especially for processing large quantities of products. Some of the fabric dyeing and finishing can be carried into the rope, and some into flat pieces of state. Higher processing efficiency rope, flat processing is not easy to produce Zhehen. Wool fabric and weft knitted fabric dyeing and washing are generally in the form of rope. The knitted fabric, wool fabric, silk fabrics and synthetic fibers are easily deformed, dyeing and finishing of the tension should be reduced as much as possible, the use of slack processing equipment.

Most of dyeing and finishing processes of chemical processing, textile materials by chemical processing them after repeated washing and drying, heat and water consumption are large, relatively high water quality requirements. In the chemical treatment process will produce harmful air and water pollution. Therefore, to determine process and design equipment, must try to reduce energy consumption, improve water use efficiency and reduce pollution.

The development of dyeing and fiber production and chemical industry, mechanical and electrical industries are closely related. Before the First World War were the subject of dyeing and finishing of natural fiber products, the processing of cotton fabric which was the largest number, followed by wool fabric, linen and silk again is textiles. Later, viscose fiber, acetate fiber and chemical fiber to begin mass production, especially after World War II the rapid growth of synthetic fiber production, so that the structure of textile products from a great change, but also the emergence of new dyeing and finishing processing technology. The earliest use of dyeing and finishing chemicals and dyes are natural products, time-consuming process cumbersome. Acid, alkali, bleaching powder and other mass production after pretreatment with dyeing and finishing them, greatly enhanced processing efficiency, changing the original pre-processing methods. The development of synthetic dyes to free people from dependence on natural dyes for dyeing and printing to provide a significant number of bright color, easy to fade for dyeing dyes in different varieties. Synthetic chemical finishing agents to make wrinkle-free, durable water repellent finishing such as access to the development of modern chemistry. Since the 40 years since the continuous dyeing and finishing equipment, to reduce fabric tension, improve processing efficiency and the use of electronic technology on temperature, concentration, speed of operation of equipment for automatic control of process conditions and other aspects of development is the rapidly improve the processing efficiency and product quality. With the development of production and people's living standards improve, the social consumption of textiles is constantly changing. Interior decoration and industrial fabrics growing requirements, it requires not only the garment fabric fancy varieties with colorful, comfortable, but also requires a washable, permanent press properties. For some special purpose fabrics made more specific requirements, such as flame retardant, resist oil. Therefore, the dyeing process technology will also continue to develop and improve with.
