zijdeachtige

Zijdeachtige is a Dutch adjective meaning silky-like or satin-like in texture or appearance. It is formed from zijde, silk, with the suffix -achtig, meaning like. The term is used for objects whose surface or feel resembles silk, without implying actual silk material.

In textiles and fashion, zij deachtige describes fabrics that are smooth, soft, and lustrous in a way reminiscent of silk. It is common in product descriptions for clothing, linens, or interior textiles where silk is imitated by synthetic blends or alternative fibers.

In mineralogy and geology, the term appears in Dutch-language descriptions of luster. A zijdeachtige (or silk-like) luster describes a soft, satiny sheen produced by fibrous or finely crystalline structures, distinct from vitreous or metallic lusters. Minerals such as satin spar gypsum are often noted for displaying a zijdeachtige sheen, especially when light interacts with fibrous thin layers.

The usage is primarily found in Dutch scientific and descriptive writing, as well as in consumer product labeling. It conveys a qualitative impression of smoothness and sheen rather than a precise measurement. See also related terms for luster in mineralogy and for silk-like qualities in textile descriptions.
