                Cashmere is a kind of special animal fiber, is the advanced raw material in the textile material. 2008, the world's annual production of Cashmere reached 21 8.6 million T, China's output reached 17 058 tons, accounting for the world's total of nearly 75%[1], is the world's largest cashmere producing country, its main production areas in China's southwest, northwest and North China and other regions. Cashmere natural color for white, green, purple, white velvet less, more purple velvet. Cashmere cashmere, wool fibers need to be divided after carding to separate the pure cashmere. The fiber structure of pure cashmere is similar to that of wool. Consists of scale layer and cortex layer, no medullary layer, its shape is close to the ellipse columnar body, the surface scale is very thin, the scale edge is smooth is blunt tooth shape, the annular wrap is covered in the fiber column body, the cover spacing is bigger than the wool.Special Fibre

                Cashmere fiber is a protein fiber, its main component is keratin (ie, keratin or keratin), it is a chain-like macromolecule with a variety of α-amino acids polycondensation, its basic constituent unit is α-amino acid, its amino acid composition and amino acid unit along the chain of polymer chains determine the characteristics of protein molecule structure, in which carbon, hydrogen, oxygen, nitrogen, The content of various elements, such as sulfur, varies with the variety, survival condition and the position of the goat. Cashmere has the texture of thin, soft, warm, good, clothing gorgeous and loved, and in the international high-grade textiles occupies a broad market.

                Dyes are colored materials that can dye fibres or other substrates and obtain distinct and solid colours, most of which can be dissolved in water and can be turned into soluble states when dyed. Dyes according to its application performance can be divided into direct dyes, reactive dyes, reducing dyes, soluble reducing dyes, sulfur dyes, insoluble azo dyes, acidic dyes, acidic mordant dyes, acid-containing dyes, cationic dyes, disperse dyes, fluorescent whitening dyes and other 12 categories, different fibers should use different dyes .Special Fibre Cashmere and wool are protein fibers, fiber macromolecules contain a large number of amino and carboxyl groups, its fiber dyeing process is the process of these groups and dyes. Therefore, the dyeing properties of cashmere wool is close, the dye dyes are generally the same, the current application of dyes have acid dyes, acidic mordant dyes, metal complex dyes, reactive dyes and so on. This paper introduces the common dyes for cashmere fiber dyeing.Special Fibre
