Red Dye Ingredients
On the composition of red dye
The dye composition used in the world has changed from ancient times to the present.
The ancient red dye is mostly taken from nature. First, madder is the source. The root of madder is rich in Alizarin, which is soaked in water, boiled and filtered through various processes to obtain a red dye. Its color is warm, long-dyed fabric, with a strong color and a quaint charm. Second, safflower is also commonly used. The petals of safflower are picked, which are twisted, soaked in water, and squeezed to remove yellow and leave red, and are dyed with it. The color is bright, but the process is complicated and time-consuming.
Later science and technology gradually flourished, and the red dye of chemical synthesis came out. These dyes are made of chemical raw materials and are mostly organic compounds. The synthesis method is based on chemical principles and accurate proportions. Synthetic red dyes are bright and uniform in color, and the dyeing of cloth is convenient, but they may be unfavorable to the human body and the environment.
