This dye has been used for centuries, and it continues to be popular in the modern textile industry. In this blog, we'll explore the molecular structure and formula of Vat Black 38, as well as its properties and uses.
Molecular Structure and Formula
The molecular structure of Vat Black 38 is complex and has been the subject of much scientific study. Its molecular formula is C66H38N10O12S2, and its molecular weight is 1239.28 g/mol. The dye is made up of several different compounds, including anthraquinone derivatives and sulfur compounds. These compounds give the dye its rich, dark color and make it ideal for use on natural fibers like cotton, linen, and wool.
Properties
Vat Black 38 has several unique properties that make it an attractive choice for textile dyeing. One of its most notable properties is its resistance to fading. Once it's been properly dyed onto fabric, it can withstand a great deal of wear and washing without losing its color. This makes it ideal for use in clothing, bedding, and other items that will be subject to regular use.
The dye is also highly soluble in water, which makes it easy to work with. It can be dissolved in hot or cold water, depending on the specific dyeing method being used.
