Inside the Workshop: A Scottish Cashmere Mill
At Johnstons of Elgin mill in Moray, Scotland, hair fibre from Mongolia is so fine it takes the fleece of four goats to produce a single sweater. The mill, operating since 1797, processes raw material through dehairing, dyeing, spinning, and knitting using methods refined over two centuries.
Cashmere quality is measured by fibre diameter. The finest grades measure between fourteen and sixteen microns, roughly one-fifth the diameter of a human hair. These fibres come from the undercoat of the Capra hircus goat, grown during harsh Central Asian winters and combed from the animal each spring.
Dehairing separates the precious undercoat from coarser guard hair. Johnstons uses a proprietary system achieving separation rates exceeding ninety-nine percent. This step alone can take several passes through machinery, each calibrated to catch progressively finer guard hairs.
Scottish cashmere dyeing produces colours of exceptional depth. The mineral-rich Highland water contributes to the process. Johnstons maintains a library of over five thousand colour recipes developed over two centuries, allowing precise matching across production runs and decades.
Knitting involves fully fashioned construction, where each piece is knitted to shape rather than cut from a larger panel. This eliminates waste and creates superior drape. Seams are linked stitch by stitch, creating nearly invisible joins without bulk.
The sustainability challenges are significant. Overgrazing by cashmere goats has contributed to desertification in Mongolia, and demand for cheap cashmere has driven proliferation of low-quality product. The best mills work directly with herding cooperatives to ensure quality and environmental responsibility.
