Shellfish purple, also known as Tyrian purple or Royal purple, obtained from hypobranchial gland of the Muricidae familly of mollusks, has been used for texile dyeing. Ocenebra inornata(Recluz, 1851), Ouu-youraku-gai in Japanse, belong to the Muricidae family, feed mainly on bivalve mollusks, and causing significant damage to oyster aquaculture worldwide. Under the purpose of this research to clarify the dyeing properties of shellfish purple obtained from O. inornata collected in Hokkaido Japan, the color tests on JIS multifiber test fabrics, colorfastness tests, and HPLC analysis were performed. As the results of experiments, these were found that direct dyeing method gave reddish purple hue on all eight kinds of fibers with excellent washing and sunlight fastness, chemical vat dyeing method gave wide range of hue from reddish purple to purple on a variety of fibers with practical color fastness, and 6.6'-dibromoindigo was detected as the main component of the pigment. Dyeing properties of shellfish purple obtained from O. inornata are similar to that of common Japanese shellfish purple snail Akanishi, Rapana venosa(Valenciennes, 1846). It would be useful to use O. inornata as the source of purple dye.

@fluor_doublet アカニシ・イボニシ・レイシガイ・ウウヨウラクガイなどから採れるようですよ。磯で大量に集めるならイボニシとレイシガイかなぁ。 https://t.co/MhNshSa13n
