We can almost divide the metal complex dyes into water based metal complex dyes and metal complex solvent dyes, and so it is in the market also. Many customers say there is color fading phomomenon after dyeing of water based metal complex dyes. What is it for contronlling this?
Unexpectedly, the fading problem of water based metal complex dyes still need to involve the geography of China's very large area, different regional climate is different, in different longitude and latitude, the sun is different, under different humidity, will also have a completely different coloring effect.
The sun's rays
The sun light is a combination of a lot of light, which has infrared and ultraviolet light. And the ultraviolet ray radiation ability is very strong, for some chemical molecules will produce a great break. Water based metal complex dyes of the chemical molecules under ultraviolet light, by its strong oxidation oxidation damage, a long period of time, slowly began to fade, this phenomenon is very common in other places.
High temperature environment
Temperature plays a very important role in the process of chemical reaction. The same substance, in the case of high temperature, chemical reaction must be a lot of intense. This is like why the tropical population, their life is often relatively short, is at high temperatures, the body's metabolism to speed up the. Any water based metal complex dyes is fading, and it is under the condition of high temperature, speed up the pace of fading.
Humidity in the air
Humidity is often ignored by people, it is difficult to be found. The mechanism which makes water based metal complex dyes’ fade is extremely complicated. Especially when it rains, now the rain is often among the acid rain, the oxygen in the air and rain into the dye, will produce a series of chemical reactions, also some additives and color in the row out of the water and makes the dye appear on the surface of expansion. To form a force, when the water evaporates, become dry contraction, this constant alternation will produce fatigue damage, dye surface will appear a little crack, and then accelerated the fading phenomenon.
Therefore, in the production process of water based metal complex dyes in the process of transportation and has reserves, will be more firmly in the control of several factors, try to slow down the color fade. The hue of color also need careful care.
