Article from The Melliand (March 1930) by H. Vom Hove of Karlsruhe on how luster arises in textiles and how it can be shown photographically. It explains luster as uniform light reflection, and discusses the effects of yarn construction, mercerization, singeing, and calendering on silk, cotton, and wool fabrics. Micrographs by transmitted and reflected light compare silk crepe de chine, mercerized cotton batiste, and matt cotton fabric before and after calendering. It also describes the metallographic projection apparatus used, with a diagram, and ends with a short bibliography.
