482-89-3 Advantages

The indigo is processed by spray drying the slurry of acid washing indigo with additive, it has advantages of:

1. Free of dust or little flying dust. The granules have certain mechanical strength, and don't create dust easily, so it can improve the working environment and sanitary condition;

2. Good flowability, which is beneficial to the automatic measuring and operation;

3. Good wettability and dispersibility, don't agglomerate or aggregate in use, and is convenient for preparing dye liquor.

4. Good storage stability, and don't absorb moisture easily, and has not electrostatic adsorption phenomenon.

5. It can also ensure the homogenic color and brilliant color light in printing and dyeing.

482-89-3 properties

The indigo is deep blue powder or granular. Soluble in hot aniline, insoluble in ethanol, in concentrated sulfuric acid as the yellow light green, diluted as blue precipitate, Lake red and red yellow was formed in concentrated sulfuric acid. Its melting point in the closed capillary is 390-392°C, and it begins sublimating slowly at 290°C. It has very good sunburn endurance and application performance.

482-89-3 Application

The indigo is mainly used to dye cotton fibre.The pop "cowboy" clothes mostly are made by indigo blue dying longitudinal yarn and white yarn interweaving; It can be used with sulfurated coloring matter; Also we can get indigo white, bromized indigo blue from it, they are well used in food coloring matter, biochemistry etc.
