FILO is an international B2B trade show in Italy dedicated to high-end yarns and fibres for woven and knitted fabrics used in apparel, furnishing, and technical textiles.

Founded in 1933, the event runs for two days and takes place twice a year, in February and September. Since September 2025, FILO has been hosted at Fiera Milano Rho in synergy with Lineapelle. In addition to spinning companies, the show also brings together dyeing and finishing mills, fibre suppliers, and organisations promoting natural and man-made fibres, serving technical teams, designers, and product managers from fabric manufacturers.
