A Mallinson's "Pussy Willow" silk process sample length, in white. Pussy Willow was the long-lived Mallinson trade name for an all silk, "radium like", fine plain weave fabric. This sample of the manufacturing process has been boiled off, or "degummed" (sericin removed) by boiling in soap and water. ["Radium" was a commonly used fabric name for a supple plain weave silk in the early 20th century.] Quality # 5459-E. This sample is from a group of six donated by the company to illustrate the discharge-printing process.
