“ Woollen and Cotton Mixtures.—This term is used to designate fabrics which are composed of the fibres of wool and cotton which have been blended or scribbled together rather than to fabrics composed of distinct threads which are all-cotton and all-wool yarns woven together. A cotton warp and wool weft fabric is a union, not a mixture. Mixtures may be recognised, when dyed, by a careful examination of the fibres constituting the yarn. When such fibres are not of the same colour, it will be found to have been due to the difference of affinity for the dye between cotton and wool. ”
