Dyeing high water consumption, high pollution industry, printing and dyeing, water consumption accounts for 80% of all textile and industrial water, the pretreatment water consumption accounted for 60% of the printing and dyeing water to 70%. In recent years, before dyeing processing equipment is mainly reflected in the water, steam, to improve the level of automation and shorten equipment processes. Wastewater, waste heat recovery, reuse equipment favored due to the continued growth of the cost of the resources.
Suitable for processing all types of knitted, stretch fabric-width continuous wet processing equipment is increasingly subject to market and the user's attention. Compared with the previous batch processing, knitted continuous processing to avoid fabric is scratched, and can save a lot of water and steam, energy saving effect is remarkable. The pre-treatment of foreign famous dyeing equipment manufacturers Küsters, Germany, Opel Tektronix, Benninger, Netherlands Brugman, Kyoto, Japan, etc.. Küsters Benninger, Opel Tektronix and high music companies have launched in recent years, elastic knitted fabric washing, scouring and bleaching continuous processing equipment, the prominent feature is the high degree of intelligence equipment control, high precision equipment manufacturing and processing, tension low, high washing efficiency. Bruggeman and Kyoto are veteran printing and dyeing machinery manufacturers, woven fabric pre-treatment equipment in China, there are still many users, but the market has been domestic products gradually replaced.
A big problem in the dyeing process sewage, its high concentration of sewage, the complicated composition containing dyes, additives, surface active agent, generally strongly alkaline, COD, BOD values. Meet small quantities in order to reduce the volume of sewage discharge, the personalized market demand of many varieties, the strong the batch dyeing equipment development momentum of a variety of low liquor ratio, water saving effect is significant, such as Ericsson Hong Kong, Germany, Andean, Shaoyang Textile Machinery and so on. Shaoyang Textile Machinery products process adaptability is very broad, the lowest bath ratio no higher than 1:4, 50% water 40%, saving steam. Italy OBEM, high temperature and pressure of the BDO cheese dyeing machine and Ericsson Hong Kong, Germany Andean production of high temperature and high pressure jet dyeing machine has been very mature and stable, high degree of automation, water-saving effect is getting better and better.
