Denim is a kind of fabric with a wide range of uses, which can be used not only for making clothes, but also for fabrics such as backpacks or vamps.

The existing denim is generally made of thick yarn-dyed warp twill cotton. The warp color is dark, generally indigo blue, and the weft color is light, generally light gray or boiled white yarn. The warp yarn is dyed by the combination of sizing and dyeing in one step, with 3/1 arrangement. There are also denim with variable twill, plain or crepe arrangement. After anti-shrinking, the shrinkage rate of the embryo cloth is smaller than that of the ordinary fabric, and the texture is tight, solid, colorful and clear.

However, when denim is used as clothing for personal wear, due to the close setting of all layers of the fabric, when the external weather is hot or cold, the external air temperature will be directly transferred to the human skin through denim, resulting in poor thermal insulation of denim fabric, reducing the comfort of people wearing denim fabric.
