The weave that creates Denim
Denim fabric usually has a twill fabric weave. And this itself makes it a very strong fabric. Do you know that it was used as sailcloth once upon a time? That is how hardwearing it is. Denim is also available in plain weave but it is mostly a lightweight denim fabric.
A special characteristic of twill weave denim is that there is a diagonal ribbing visible on the face of the fabric, which sets it apart from other cotton fabric. This is the result of the special twill weaving. Fibers are weaved on a loom in a twill weave pattern.
The Twill diagonal weave of the denim fabric also gives it a good enough drape, especially for such a thick fabric.

Have you wondered why your jeans is white on the inside and blue on the outside?
It is because when weaving denim, Warp thread is dyed indigo whereas weft thread is left undyed. This special weaving in which colored thread (mostly indigo) is crossed with white thread results in a two-tone look which is very attractive. The color sits on the face of the fabric and the white pulls to the backside.
Denim was given the popularity it enjoys in 1873 by two Americans Jacob Davis and Levi Strauss. Levi Strauss was a cloth merchant and Jacob Davis a tailor. Jacob Davis got an order to sew up a pair of trousers which would wear well and be sturdy enough. Mr. Davis approached Mr. Staruss and purchased from him denim which was as sturdy as sturdy could be. Later they went on to form a partnership of making these same trousers which is known as jeans. Rest is history. You can read more of the history of jeans here
Different types of Denim fabric
1. 100% cotton Denim/Rigid denim
This is the normal denim without elastane fibers. This fabric is very durable, hard wearing and versatile.
2. Denim according to type of twill weave
This denim can have different twill weave patterns and thus vary in its structure. In a right hand twill, the twill line runs diagonally from bottom left to top right – this results in a tighter woven fabric. Left-handed twill creates a softer denim. 3×1 and 2×1 weave are the most common twill weave. The best denim has a 3*1 twill weave ie. three warp threads to every one weft thread.
3. Raw denim
This is also called unsanforized denim or unwashed denim or Dry denim. This is a fabric which is not washed or treated in any way after dyeing.
The washing of denim fabric is usually done so that the fabric becomes soft and also to eliminate shrinkage. Basically what we call in sewing as pre-washing. Raw denim can shrink upto 20% in the first wash.
Raw denim has a very even look without any of the distressed look we are familiar in jeans. Whatever distressed look is desired will have to be obtained naturally by fading and stress. This is a natural process which some people consider more desirable than the factory made distressed look. It is important that you prewash raw denim before sewing / wearing.
4. Sanforized Denim
This is denim fabric which is processed so that it does not shrink after wash. Most of the denim other than raw denim is Sanforized.
5. Colored denim
There are two types of coloured denim – blue and the rest of the colours. The blue colour or shades close to blue is given with a process known as indigo dying. Sulphur dying and other dyeing gives denim other colours like Black, pink, grey, mustard, green, red etc. Tinting is done to give a deeper tint to denim.
6. Stretch denim
This is denim incorporated with stretchy synthetic elastane fiber like lycra/ spandex which gives it stretch. The stretch of the fabric will depend on the percentage of elastane in it. The elastane fibers are used as weft yarn.
7. Selvedge Denim

Colour of the fabric fades as a result of the abrasion with the stones and creates an attractive contrast with the indigo colour. The fabric is then rinsed, softened and dried. There are many other washes like enzyme wash, stone wash that the denim undergoes when it is made into your lived-in jeans. You can read about the different jeans washes and surface treatments here.
