Denim has long been a staple in fashion, and the indigo blue hue has become synonymous with this iconic fabric. From classic jeans to stylish jackets, indigo blue holds a special place in our closets and our hearts. But what makes this shade so timeless? In this article, we will explore the history, significance, and enduring popularity of indigo blue in the world of denim.

Indigo blue denim jeans have become a staple in the fashion industry, loved and worn by people of all ages and genders. The rich, deep blue color of indigo dye creates a timeless and versatile look that can be dressed up or down for any occasion.

Natural indigo is now being used by several fashion retail giants such as H&M on a large scale to replace synthetic indigo dye for developing safe, green, and sustainable jeans.

Indigo has been in use as a blue colorant for thousands of years as a natural dye, which was produced from the Indigophera plant in India and China and with woad in Europe.

A deep, intense shade that comes from a natural dye, indigo sits between blue and violet in the colors of the rainbow. There is much debate over what color indigo represents most and if it is closer to a blue or purple shade; in this article we will explore the frequent questions asked when researching, what color is indigo?

First the leaves are harvested and dried in the sun while being flipped repeatedly by a broom. Next they are fermented to create sukumo, a concentrated version of the dye. This is mixed with lye and lime before being fermented again. The depth of colour will depend on the length of time the sukumo is left to ferment.

This is my last post for the Old Year. And since the Lunar-Solar New Year is all about cherishing and respecting 'Mother', this last post is in service to the Motherlands, the first mother. The land of birth and first breath.

Indigo dyeing is a traditional dyeing process that has been practiced for thousands of years in various regions of the world. The indigo dyeing process utilizes a natural pigment obtained from the leaves of the indigo plant, resulting in a beautiful, deep blue color that is unique and unmatched by synthetic dyes.

If you don't want to mess with Indigo Vats, reducing and oxidizing, not to mention crocking (think the "Tuareg, The Blue Men of the Sahara, an ancient Berber tribe that ranges from southern Morocco...", not the Blue Man Group) we have a permanent Fiber Reactive Dye color that we added awhile back to our expanding line of professional dyes for natural fibers!

Natural indigo is now being used by several fashion retail giants such as H&M on a large scale to replace synthetic indigo dye for developing safe, green, and sustainable jeans. Since natural indigo originates from natural resources, it is treble the cost of synthetic indigo dye.

Vat Blue 1 synonym is Indigo Blue Granular or Powder. Vat Indigo Blue is dark blue powder,our content of indigo blue is above 94%.The product is highly dyeing uptake, compatible with various fixing agent. And we have different types for difference application, yarn dyeing special, woven fabric special, liquid special, etc. The highest concentration could be 97.5%.

My first forays into natural dyeing began with the vibrant blue dye of indigo. Indigo is the name given to the dye that comes from plants (of which there are many species) containing the indican compound that produces an incredible blue dye. Used throughout Asia, South America & Africa, indigo has a rich and vibrant history & is one of the oldest know natural dyes used by man. The process of dyeing with indigo is unlike most other natural colourants, setting it apart from many other dyes. I am going to show you how to make a simple indigo vat based on a recipe by French chemist, Micheal Garcia known as the 1-2-3 vat, using as the name suggests three ingredients which are indigo – Lime – Fructose.

Indigo dye is an organic compound with a distinctive blue color. Indigo is a natural dye extracted from the leaves of some plants of the Indigofera genus, in particular Indigofera tinctoria. Dye-bearing Indigofera plants were commonly grown and used throughout the world, particularly in Asia, with the production of indigo dyestuff economically important due to the historical rarity of other blue dyestuffs.[1]

Indigo can dye all natural fibres. It gives beautiful shades of blue — from the palest summer sky to an almost purple black. The colour achieved depends on the type of vat, the concentration of indigo, and the number of dips.

Indigo is a pigment extracted from the leaves of indigo-bearing plants and is the oldest natural source of blue dye in the world. Humans have used indigo to dye natural fibers for thousands of years, with traditions spanning continents and cultures. Indigo dye was common in ancient civilizations in Mesopotamia, Egypt, Britain, Mesoamerica, Peru, Iran, and West Africa. The oldest known indigo-dyed cloth was found in Peru and dates back 6,000 years.

A few weeks ago my Aunty (the very creative and inspiring hand weaver, spinner and textile designer Madeleine Jude) very kindly spent the day giving me a little glimpse into the alchemy of indigo dying.

Indigo has been used in natural dyeing since ancient times to create beautiful shades of blue, from very light to very dark. It can be a bit intimidating for natural dyers to work with indigo for the first time, as it’s not a water soluble substance and the dye pot needs to be deprived of oxygen in order for the indigo dye to bind to the fabric.

“Two problems make indigo a dye unlike any other dye in the universe,” said Cynthia Thayer at the 2004 Common Ground Country Fair. It does not dissolve in water, nor does it adhere to material.

The production process of sulphur black is based on 2,4-dinitrochlorobenzene, which is hydrolyzed under alkaline conditions to obtain 2,4-dinitrophenol sodium salt, which is then added to sodium polysulfide solution for vulcanization. After oxidation, filtration, The finished product is dried.

Sulphur dyes are complex heterocyclic molecules or mixtures formed by melting or boiling organic compounds containing amino or nitro groups with Na-polysulphide and Sulphur. Sulphur dyes are so called as they all contain Sulphur linkage within their molecules.
