Founded in Philadelphia in 1911 as a cotton warp dyehouse, Caledonian Dye Works is now a fourth-generation family business providing commission dyeing for yarns and blends. Kimberly F. Livingston leads the company, which combines computerized color matching with package and skein dyeing and accommodates lots from 30 to 1,000 pounds. Its color-matching lab and focus on smaller and mid-sized dye lots reflect a long-standing role in the region’s textile trade.
