Denim Fabric
What Is Denim Fabric and How Is It Made?
Denim is a durable cotton twill fabric, traditionally woven with indigo-dyed warp yarns and white weft yarns, giving it its signature blue color and diagonal ribbing. Known for its strength and longevity, denim is the go-to fabric for jeans, jackets, skirts, bags, and workwear.
Denim is made using a twill weave, where the warp thread (usually dyed) passes over two or more weft threads (usually undyed). This creates a diagonal texture on the face of the fabric and a lighter-colored reverse side. Most denim is made from 100% cotton, but stretch denim includes a small amount of spandex or elastane for flexibility and comfort.
After weaving, denim can be washed, sanded, distressed, or bleached to create different finishes and styles. Popular types include raw denim, selvedge denim, stretch denim, and bull denim.
