The sustainable development of flame retardant industry

China's fire-retardant industry, annual water consumption of more than 10 billion tons, waste water production accounts for the country's sixth, of which the most polluting industry, the most serious waste water discharge, accounting for about 80% of water consumption by unit weight of textile goods is foreign Of 2-3 times. Dyeing and finishing most of the higher temperature, the energy consumption, the consumption is 3-5 times abroad. Energy-saving emission reduction is an important policy formulated by the state, how to put the implementation of energy-saving emission reduction in place is the textile printing and dyeing and dye production industry's two common responsibilities and mission.
Flame retardant industry Reactive dyes are the most important dyes for cellulose fiber dyeing. Because of the broad spectrum, bright color, excellent performance and strong applicability, it is widely used. The world's annual output of about 250,000 tons, accounting for about 20% of the total dye. China's annual output of reactive dyes in 2005 about 160,000 tons in 2006, 174,000 tons [1], accounting for 25% of total output. However, the utilization rate of reactive dyes is not high, generally 65% ​​~ 72%, resulting in a large number of non-ferrous sewage, due to the consumption of a large number of electrolytic pressure, resulting in serious concentration of inorganic salt in waste water, greatly increasing the difficulty of treating reactive dyes. Printing and dyeing industry, cold paddle dyeing, wet short steaming dyed, flame retardant industry, small bath than dyeing and low temperature, low salt dye development, and promote energy conservation.
Flame-retardant industry in the past five years, the world's dye-resistant industry development of the dye were: 141 in 2001, 190 in 2002, 174 in 2003, 150 in 2004 and 164 in 2004; of which new varieties of reactive dyes were : 26,46,39,30,35, accounting for about 20% of the total new varieties. These new varieties of reactive dyes to solve the energy-saving emission reduction as a part of the target.
1, cold paddle dyeing reactive dyes
Cold-rolled heap dyeing is the flame-retardant industry in the low temperature does not dip the dye and alkali mixture of dye (through the proportion of the pump were the dye and alkali agent into the pad), the use of roll extrusion to dye the surface of the fabric, and then Roll up the stack, at a low temperature for a certain period of time to complete the adsorption, diffusion, fixation of the three dyeing process, the final water wash color. The process is characterized by a short process flow, the equipment is simple, because in the cold under the dyeing, thus saving energy, and has a fixed rate higher than the conventional steaming method, there is no dye swim and other ills. The process of alkali resistance to the stability of the dye, in the concentrated alkali, low temperature conditions do not precipitate, flame retardant industry and the direct low dye. In order to make the dye have good alkali resistance, the use of supramolecular chemistry theory for dye - dye, dye - additive compound enhancement, reduce the degree of dye association, increase the solubility of the dye.
