With the social progress and the improved quality of life of the people, Car Flag Manufacturers, Car Flags Manufacturers the growing emphasis on environment and health level. Wear the "green textiles, eco textiles" the needs of today's world people's lives. The development of clean production of the textile industry, Beach Warning Flags For Sale the use of green modes of production in favor of protecting the ecological environment, to provide consumers with eco-textiles is the world's textile industry into the 21st century global themes, is related to the quality of human existence and sustainable development. The green staining technology is the future direction of the focus on the development of textile dyeing.
The main features of the green staining technique is the application of harmless dyes and auxiliaries, the use of polluting or less polluting process of textile dyeing process. Less water and stain colored stained discharge sewage less and easy purification, low energy consumption, the staining product is "green" or eco-textiles. For this reason, in recent years a lot of research, propose and promote the application of less pollution or ecological requirements of the new dyeing process.
New dyeing process, including non-water, less water stain, energy-saving dyeing, stain solubilization, new paint stain, short processes, dyeing and finishing of the multi-effects, computer applications and controlled dyeing. Car Flags Manufacturers
A. Natural Dyes Cheap Racing Flags
With some varieties of synthetic dyes by the disabled people's interest in natural dyes and heavy new concentrated, mainly because most of the natural dyes and environmental and ecological compatibility, biodegradable and less toxic. The raw material of synthetic dyes are petroleum and coal chemical products, these resources are consumed quickly, from this point for the development of natural dyes is also conducive to ecological protection. Although natural dyes Because of its many deficiencies, can not completely replace synthetic dyes, but some of the alternative or complementary as synthetic dyes is valuable.
The chemical structure of natural dyes is not very clear, the extraction process is very backward. Therefore, the extraction and application of research and development it is necessary, especially the comprehensive utilization of plant leaves, flowers, fruits and roots, and other industrial waste to extract the natural dyes is of great significance. With the development of biotechnology, genetic engineering is expected to get good performance and high yield natural dyes. Performance and structural understanding about natural dyes is not worth to strengthen research. Car Flags Manufacturers
Two. The dyestuffs alternative dyes
Ecological textiles standard with the Eeo-Tex Standard 100, the gradual improvement of synthetic dyes is disabled, forcing the dye manufacturers in recent years has produced a large number of synthetic dyes that meet the ecological standards in the future will have more dye and the development of the dyeing process.
3. High fixation rate or infection rate on the high dye staining Custom Swooper Flags Wholesale
One of the main ecological problems of the staining dyes in the dyeing wastewater pollution. Development and application of high infection rate, or high fixation rate of the dye, can greatly reduce the dye in the wastewater, but also can improve the utilization of dye. Has developed a high fixation rate of activity, disperse and cationic dyes, Custom Outdoor Banner Flags reducing the residual dye in the wastewater, but it also reduces the amount of water washing after the staining, the volume of wastewater is also reduced.
4. High color fastness of dyes dyeing
The close relationship between the ecological standards of the dyeing of textile and dye fastness, past applications of water-soluble dyes, direct dyes such as the dyeing of cellulose fibers, Car Flags Manufacturers dyeing wool and silk and acid dyes, dyeing poor wet fastness. Such dyes are not only to the level of textile ecological variation, processing and dyeing wastewater is difficult to purify. Such dyes has gradually been replaced by a high color fastness of the dye, Custom Feather Flags Wholesale for example, the application of high wet fastness of reactive dyes.
Disperse dyes is mainly used for dyeing of synthetic fibers and acetate fibers. The low solubility of disperse dyes, so good wet fastness, wastewater easy purification. Is research and development in recent years for wool, silk textiles dyeing of disperse dyes, and especially suitable for fiber and synthetic fiber blended fabric. Car Flags Manufacturers To expand the application of such dyes is also conducive to the promotion of "green" dyeing process.
