* Black Selvedge Jeans Material-The difference between sulfur black and reactive black

Sulfur black is black shimmery granular and is mainly used for dyeing cotton textiles.

The difference between sulfur black and reactive black

1. The two components are different

Active black is the main component is carbon,Sulfur black contains more sulfur element.

2. Sulfur dyes are cheap, and the dyeing process is not environmentally friendly.

At the same time, the fabric strength may be slightly damaged after dyeing, and there may be a pungent odor.

Reactive dyes are slightly more expensive than sulfur dyes, and there is no toxic gas generated in the production process, which is environmentally friendly compared to the production process of sulfur dyes.

3. Active black is mostly used as an adsorption material, while sulfur black is mostly used for dyeing.

* How to distinguish sulfur black and reactive black?

Question:A piece of sulfur black cloth and a piece of reactive black cloth are put together, how can you tell which is which? ? ?

It is impossible to tell what the respective components are just by looking at the appearance. Considering that the color fastness of active black is obviously weaker than that of sulfur black and disperse black, some strong oxidants such as hydrogen peroxide, sodium hypochlorite or acid high manganese can be titrated on the two samples respectively. The potassium acid aqueous solution is soaked for a few minutes to see the effect. The fading and lightening are active black, which is not resistant to acid and alkali and peroxy radicals, and almost no discoloration is sulfur black. Reactive dyes and acid, alkaline and direct dyes are all in the same grade and are not resistant to bleaching.
