What kind of dyes for polyester fiber

As experts in the field of textile chemistry and dyeing and finishing, Donghua University key laboratory of ecological textile Mao Zhiping Director Professor, with the development of polyester fiber, specific to this type of fiber with disperse dyes will in the future in terms of features more prominent, broad market prospects will be more. Dyeing of polyester Microfiber uniqueness increased difficulty according to Professor Mao Zhiping introduction, into island-polyester fiber, Orange silk and sprayed into three categories. The most striking feature of polyester fiber, is the significantly lower than the normal fiber monofilament fiber. For cotton, polyester Microfiber clothes, comfortable, beautiful and warm, breathable, has good draping and fullness, in terms of drainage and pollution prevention also has a clear advantage. Mao Zhiping Professor explained said, polyester Super fine fiber in printing and dyeing processing process in the will encountered many technology challenges, to PET Island Super fine fiber imitation suede cashmere varieties for cases, a is dye deep sexual difference, because Island type Super fine fiber surface area to is greater than General polyester fiber many times, caused fiber surface reflection light is large, and was dyeing and weaving identified shades of and fiber surface reflection light and the by fiber internal again returns to external of refraction light about, so in dye dosage same situation Xia, island type Super fine fiber more general polyester fiber its color depth to shallow many. Second, color fastness, and this is also because the Microfiber surface area than conventional polyester fiber many times, in the case of dye amount the same, many less amount of dye per unit area, such as to achieve the same apparent depth, dye should be in the same proportion also increased, resulting in doubling the amount of disperse dyes, color fastness sharply. Third, levelling poor of disperse dyes for dyeing rate associated with the RADIUS and the surface area of fiber, Micro Fiber as the linear density of small surface area, fast dye adsorption rate, prone to phenomena of dye unevenness. These factors on dyeing of polyester Microfiber fabric manufacturer and technical level of printing and dyeing enterprises put forward higher requirements. Polyester Super fine fiber dedicated dye performance constantly upgrade Shang century 90 generation, abroad leading of dye production enterprise with nationality its powerful of research and development strength, first development out for polyester Super fine fiber features of printing and dyeing products, as de Si Da of large love Nepalese grams Secretary MF, and CC, and ETD, and AM, series and hens Mai of trust CR series,, these dye varieties and the supporting printing and dyeing technology better to solution has polyester Super fine fiber fabric in printing and dyeing process in the of dye deep sexual and uniform dye sexual poor problem, in at home and abroad polyester Super fine fiber dedicated dispersed dye market made has led status. 2000 yihou, domestic dye enterprise under import products in domestic application in the exists of series of defects, constantly perfect products and application technology, eventually independent research and development success polyester Super fine fiber dedicated dye products, as residential promise its company of residential promise can lung DRD series, and ERD series, and HRD series, Dragon Sheng company of LRD series, these products of dyeing performance has reached or over abroad similar products, its price/performance more highlight, 2003 yihou market share quickly expanded. Currently in China polyester Super fine fiber dedicated dispersed dye market in the, de scholar up, and hengsimai, and Klein, and more smell, transnational corporations occupies about 20% of market share, its silker main is abroad some high-end fabric procurement commercial or specifies dye brand of procurement commercial, but its market share is every year decline of trend; domestic of Long Cheng, and leap soil, and yabang, and Agfa-Gevaert, scale above dye producers, its products to General polyester of disperse dyes mainly, capacity huge, for Super fine fiber of dye main to supply peach skin cashmere mainly, its market share and the positioning comparison stability and clear, has been maintained in 30%~40% of level; to residential promise its company for representative of domestic professional dye production enterprise, by virtue of its in Super fine fiber, new textile fiber and the fabric subdivision market of unique advantage, to characteristics products and first-class of technology application service for led, development Monster fine fiber dedicated of high upgrade sexual, and high washed fastness, and high Sun fastness, more series dispersed dye products, replaced abroad products of market, filled has domestic blank, market share every year expanded. Special dye for polyester fibers have broad market prospects according to who forecasts, domestic fiber production will increase at a rate of 9% per year, by 2013 the domestic pet Superfine fiber production at 460,000 tonnes, which used to imitation Suede, peach skin and silk-like and other high-end clothing and home textile fiber production will reach about 250,000 tons. Mao Zhi-ping Professor, as the degree of industry concentration increases and more for dyeing of Superfine fiber characteristics of functional requirements the emergence of special market size of disperse dyes for polyester fiber will also gradually expand. According to industry data and statistics, 1 polyester Microfiber fabric according to the different requirements for properties of deep color, typically takes 20 kg ~80 kilogram of disperse dye, one of Sea-Island fiber fabric and high water, high light fastness requirements of high-end fabric dye consumption will be more. According to the estimation of Professor Mao Zhiping, differentiated, function as domestic polyester fabric to the direction of continuous development, special demand of disperse dyes for polyester fiber in China will increase at a rate of 15% per year by 2013 and domestic demand will reach 15,000 tons.
