Dobby is a special type of weaving process used in textile manufacturing to create patterns in fabric. It's like a mechanical system that controls how threads are woven together to make decorative designs. When you see clothes or home textiles with small, repeated patterns like diamonds, dots, or simple florals, these are often made using a dobby loom. This method sits between simple weaving (which makes basic fabrics) and jacquard weaving (which makes very complex designs). Many textile companies use dobby weaving because it's cost-effective for producing medium-complexity patterns that are popular in fashion and home furnishings.
