A Century of Reassurance

BTTG® was formed in 1988 from the merger of the Shirley Institute and WIRA, both established post-WWI for textile research. Since 1918, we have contributed significantly to textiles, including Nobel-winning work on chromatography, the Martindale test, the tog test, and pioneering Manikin testing.
