The Shirley Institute was established in 1920 as the British Cotton Industry Research Association at The Towers in Didsbury, Manchester, as a research centre dedicated to cotton production technologies. It was funded by the Cotton Board through a statutory levy. A significant contribution to the purchase price of The Towers was made by William Greenwood, the MP for Stockport, who asked that the building be named after his daughter. The Institute developed Ventile, a special high-quality woven cotton fabric. It also developed the tog as an easy-to-follow measure of the thermal resistance of textiles, as an alternative to the SI unit of m2K/W.
