Denim is a kind of warp twill fabric, which is a kind of colored fabric composed of high-specified, that is, thicker cotton thread. Generally, the surface of denim fabric is indigo blue. This is because indigo blue and darker warp yarns are generally used when weaving denim fabrics, while light gray or white cotton yarns are used for weft yarns. When weaving a twill weave on a loom, the color of warp yarn is generally shown on the front side and the color of weft yarn is shown on the back side, so the front side of the denim is indigo.
Cotton fabric has the characteristics of moisture absorption and breathability, and comfortable wearing. At the same time, because denim is woven with thicker yarn, it is rough and wear-resistant. Denim can be washed with water. There is no special requirement for washing. It has a long service life and has been loved by the majority of people. Denim first began in the western United States and is usually made into clothing by herders. It is also called "indigo labor cloth". With the development of the times and the spread of culture, denim is accepted and loved by more and more people.
The product value of fabrics made of denim will not decrease over time, or even increase. Because in the current society, many consumers like retro style, old style, and even deliberately buy finished products in this area, so the fabric made of good denim will not depreciate basically.
