The Union of Belgian Textile Workers (Dutch: Textielarbeiderscentrale van België, TACB; French: Centrale des Ouvriers Textiles de Belgique, COTB) was a trade union representing workers in the textile trades in Belgium.
The union was founded in 1898 as the National Textile Workers' Association of Belgium, linked to the Belgian Workers Party.
However, after World War I, the Flemish leadership decided to centralise the union, and the Verviers federation left, only rejoining in 1935.
In 1945, the union was a founding constituent of the General Federation of Belgian Labour.
[1] The union's membership peaked at 79,953 in 1953, then fell steadily, in line with employment in the industry.
