Why are jeans a wardrobe staple
Do you recall the 1976 song by David Dundas
When I wake up in the morning light
I pull on my jeans and I feel all right
I pull my blue jeans on, I pull my old blue jeans on
I loved the song back then. Even though talking about old blue jeans seems like a tautology like saying a black raven or a white swan. Jeans are blue and best when old.
The unique chemical properties of the indigo dye made jeans so popular that they became the traditional American clothes. In contrast to other dyes, indigo only sticks to the outside of the threads. When the fabric is washed some of the dye gets lost. Over time, the pair gets the soft, lived-in feeling.
For those, who can’t wait that the indigo-dyed raw denim (dark wash, i.e. not pre-washed) looses its pigments, brands offer medium wash, light wash, stone wash, sand wash and even distressed. Sandblasting jeans to create a “worn‐out” look started in Turkey in the 1990. Sand blasted means that an employee has to treat the pair with a sandblaster. This means the person inhales a lot of fine silica particlur matter, which may lead to health problems (silicosis) and even death.
Today, jeans are a wardrobe staple worldwide. They are an essential in Business Casual Style, for Casual Friday and the weekend.
What is colored denim
Denim is the fabric out of which jeans are made. Colored “denim” pops up as a perennial trend every now and then. It again has a moment. To obtain colored denim sulfur dyeing is applied. It creates all kinds of colors like purple, pink, red, burgundy, orange, yellow, green, mint, brown, mustard, black, you name it. See this guide how to look stylish in denim.
In contrast to indigo dye, sulfur dyes cover the thread thoroughly, i.e. also in the inside. Therefore, a colored denim feels stiffer than an indigo-dyed denim. It never will get the cool, lived-in feeling like jeans.
Historically, Levi Strauss, who introduced the jeans, made first denim trousers cut and made exactly the same like jeans except they were dyed brown. These brown pants were called “ducks.” Despite brown also is a non-boring neutral, the ducks became less popular over time. The blue version was so much more comfortable on the skin than its brown twin. For this reason colored denim fails to push the old blue jeans off the market.
What is denim
Denim is a heavy cotton twill fabric made of 100% cotton. It comes in different weights per square yard of fabric. For instance, 6 oz means the fabric weights 6 oz Lightweight less than 12 oz, medium weight 12 to less than 16 oz, heavy weight or Alaska-weight 16 to less than 32 oz, monster-heavy weight 32 oz.
Denim is used for all kinds of clothes, not only trousers or jeans.All jeans are denim, but not all denims are jeans. #fashion #triva Click To Tweet
Often cotton is blended with rayon and spandex to produce a stretchy, more comfortable material. However, technically spoken this blended fabric is not denim.
How does sulfur dye work
Sulfur dyes are non-soluble in water. At temperatures around 80o and alkali pH-values, the dye particles disintegrate when a reducing agent (e.g. sodium sulfide, sodium hydrosulfide) is in the solution. Under these conditions, the dye particles become soluble in water and can be absorbed by the fabric. Salt facilitates the absorption. After removing the fabric from the dye solution, the dye oxidizes in air. This oxidation makes the color insoluble in water. Hydrogen peroxide or sodium bromate also can be used for oxidation in mildly acidic solutions.
Environmental impacts of dyes
The high solubility of the dyes, especially the reactive, direct, basic and acids ones, in water pose a challenge to remove them. Thus, they become an environmental problem for waterbodies. The color reduces the penetration of light thru water. Consequently, the photosynthesis rates of water plants goes down. Since photolysis produces oxygen that dissolved in the waterbody, the reduced concentrations affect the aquatic biota.
Textile dyes also act as toxic, mutagenic and carcinogenic agents (see references for more information). They accumulate in the bodies, especially of those species that are at the end of the food-chain. Since sulfide agents are toxic, they are (slowly) substituted in the Western World by applying glucose in basic solution.

How I wear colored denim
My first pair of denim pants were cream with a floral Laura Ashley like print! In my opinion and those of my classmates, they looked like PJs. I wasn’t allowed to dye them because the color could rinse in the laundry. As 12 years old girl I fought a fashion battle me to get my first pair of jeans. These colored pants were also an argument “You didn’t wear your printed pair.”
