About Us

Shirley® is a wholly owned subsidiary of BTTG Ltd. BTTG Ltd. superseded the British Textile Technology Group, which was itself formed during the late 1980’s from two globally renowned textile institutions; the Wool Industries Research Association (WIRA) established in 1918 and The Shirley Institute; the latter set up to support the cotton industry in 1919.

Shirley®, whilst keeping the 'family' name – in fact a given name of the daughter of one of the main benefactors of the Shirley Institute – has been operating as a trading company within BTTG since July 2003.

Shirley®focuses on the services required by the more traditional sectors of the textile industry.
