paddle dyeing
A method employed in dyeing the more fragile
leathers, including bookbinding leathers, skivers,
etc., that might otherwise be damaged by the
vigorous mechanical action involved in drum
dyeing. Paddle dyeing requires considerably higher
ratios of dye solution to weight of leather than
are used in drum dyeing, and utilizes the dyes
less effectively; however, it does have the
advantage that the leather is visible during
dyeing and adjustments to shade and strength can
be made continuously. (248 )
