Denim fabric is a sturdy cotton twill textile, characterized by its diagonal ribbing. It is most commonly used to make jeans, jackets, and other clothing items. The fabric is typically dyed with indigo, giving it a distinctive blue color, although it can also be found in various shades and colors. The weaving process of denim involves two yarns: the warp and the weft. The warp yarns are dyed, while the weft yarns remain white, creating the unique appearance of denim. This fabric is known for its durability and comfort, making it a popular choice for casual wear and work attire.
