UNIQLO can secure stable, high-volume supplies of top-quality materials at low cost by negotiating directly with materials manufacturers, and placing large-volume orders. The materials used for our core items are particularly important. Our in-depth research and experimentation generates multi-layered improvements in the functionality, feel, silhouette and texture of our clothes. For example, we source denim to specific spinning standards and dyeing specifications from Kaihara Corporation. We also develop materials with synthetic fiber manufacturer Toray Industries, a strategic partner, to create HEATTECH.
