IMPORTANT EARLY SYNTHETIC DYES Chemistry Constitution Date Properties Compiled by Textile Conservation Interns Andrea Bowes Stephen Collins Shannon Elliott La Tasha Harris Laura Hazl ett Ester M~ th~ Muhammadin Razak Pugi Yosep Subagiyo Edited by Mary W. Ballard, Senior Textile Conservator Conservation Analytical Laboratory Smithsonian Institution 1991 Preface This notebook presents information on a limited number of important early synthetic dyes as recommended by the extensive work of Dr. Helmut Schweppe in the field of dye analysis. A great deal of the data has been abstracted from the well-known encyclopedia on dye structure and properties, the Colour Index, published jointly by the American Association of textile Chemists and Colorists and the Society of Dyers and Colourists. The purpose of this manual is as an aid to textile conservators in their laboratories. It is distributed by the Conservation Analytical Laboratory, Smithsonian Institution, with the kind permission of the American Association of Textile Chemists and Colorists. For a complete review of all known dye structures and chemical properties of dyes, the reader is referred to the master volumes of the Colour Index. Mary W.

Professional organization, located in Research Triangle Park, North Carolina. Designs and promulgates textile testing standards, published annually in AATCC Technical Manual. Numerical references compare to Grey Scales for chnages in color or Grey Scales for changes in staining: 5 (least) to 1 (most). Lightfastness of dye on fabric compare to standards 1 (lowest) to 8 (highest fastness). Carbonising: Operation in wool processing. Designed to removed vegetable impurities (burrs, etc.); occurs before dyeing. With woolen piece goods, fabric is immersed in 5% (wt/vol) H2S04' squeezed. dried at 600- 700C. then baked at 1100C for 5 minutes. Fabrics will contain about 6% H2S04' Decreases affinity of fabric for acid dyes. Crabbing: Operation in wool processing. Cloth under tension passes through boiling water and is quenched. Purpose is to prevent/correct cockling and distoriton of weave structure or pattern. particularly to plain weaves. Decatising: Steaming. Operation in wool processing. Dischargeability: Characteristic of certain dyestuffs, to be reduced (destroyed) and not to interfere with the shade of subsequent dye on a printed cloth. Dye Method: For wool fibers, yarns and fabrics. Refers to acidity required in dye bath condition for the successful application of the dye to the fiber: ( 1) Nearly neutral (pH 7.0-7.5) (2) Weakly acidic (pH 3.5-5.5) (3) Sulfuric acid (pH<3.5). Exhaustion: A postiive characteristic of a dye. refers to the transfer of the dye from the bath (dye liquor) into the fiber. Illuminating color: Dye not affected by the reducing agent used for a discharged dye. ISO: International Organization for Standardization. Professional organization • located in Geneva, Switzerland. Designs and promulgates (textile) testing methods. Test methods for the determination of fastness also use Grey Scales. Levelness: A positive characteristic of a dye. Refers to the overall evenness of shade througout the piece of c l oth or skein of yarn. Also used to indicate thoroughness of penetration into the material. i.e. in cross-section. Milling: Synonym for fulling. Operation in woolen processing. Designed to felt the cloth. increasing fullness and density. creating a pile. Potting: Operation in wool processing similar to crabbing. Fabric is wrapped around iron roller. submerged in a cold bath; bath is slowly raised to the boil. Used to obt ain bright finish and soft handle found in billiard cloths. SDC. Society of Dyers and Colourists. British professional organization. Devises and promulgates textile testing standards. First fastness data published in the Society' s Journal in 1884. Stovin~: A bleaching operation during wool processing. Involves the use of sulfur or sulfur dioxide. Bibliography Abrahart, E.N. Dyes and Their Intermediates.
