Scouring

Definition and stakes

Aldred Farrer Barker,  1911 Encyclopædia Britannica (1911)

“ Many firms now steep the wool previous to the true scouring operation, the object being to scour the wool with its own potash salts, to obtain wash-waters so fully charged with the potash salts that these salts, &c., may be readily extracted and put to some good use, and lastly to save the artificial scouring agent employed in the true scouring operation. The scouring of wool has passed through many vicissitudes during the past fifty years, but to-day the principle upon which all scouring machines are based is that wool naturally opens out in water. ”

Franklin Beech,  The Dyeing of Woollen Fabrics

“ The kind of scouring that the fibres receive in this case need only be of a comparatively light character, but it must never be omitted, even for dark shades, as the traces of grease which the fibre contains are the causes of nearly irremediable stains in the dyeing operations. Even in dyeing black wool it is of the greatest importance to have the fibre suitably scoured. ”

Aldred Farrer Barker,  1911 Encyclopædia Britannica (1911)

“ The washing which a fleece may have received on the live sheep is not sufficient for the ordinary purposes of the manufacturer. Scouring. On the careful and complete manner in which scouring is effected much depends. The qualities of the fibre may be seriously injured by injudicious treatment, while, if the wool is imperfectly cleansed, it will dye unevenly, and the manufacturing operations will be more or less unsatisfactory. ”
