Combing is an important process in textile manufacturing that helps create high-quality yarns and fabrics. It's like giving hair a thorough brushing - the process removes short fibers, impurities, and aligns the remaining long fibers parallel to each other. This results in stronger, smoother, and more uniform yarns. Products made from combed materials are generally more expensive and higher quality than uncombed ones. You might see this process mentioned particularly with cotton (combed cotton) and wool processing.
