We all own multiple pairs of jeans and we wear them with pride. Whether it’s a work day or a grand occasion, they never fail you – especially the classic blue denim.
They are the granddaddy of fashion that refuses to give away its ‘cool’. This does not imply that the other colors don’t hold their own ground when it comes to denim. But, for the purposes of this article, we will stick to the classic blue jeans.
So, let’s get into the nitty-gritty of the chemistry behind the classic blue jeans.
It all starts with cotton yarn, which looks white, but with the aid of dye creates that blue color that everyone loves to see. The awesome part of dying the yarn is that it turns yellow, and with the help of oxygen, turns blue. It is then coated with starch and the weaving process starts. It’s an intricate process that gives provision for the various designs that you’ve come to love and adore. When woven into denim, these blue threads run parallel in the fabric and are put together with white cotton “weft” thread, which runs perpendicular. Look down at your jeans, and you’ll see what I mean.
Let’s get back to reality. Who really cares about the chemistry of jeans when you can get them looking so awesome?
