Chóu bù (silk fabric) is a compound noun formed by combining 绸 (chóu), meaning 'silk'—a luxurious textile traditionally made from silkworm cocoons—and 布 (bù), meaning 'fabric' or 'cloth'. Together, they specify a smooth, lustrous, tightly woven textile made from silk fibers. Though modern versions may include silk blends, the term evokes high quality, elegance, and traditional Chinese craftsmanship.

This word is commonly used in contexts involving clothing, tailoring, interior decoration, and cultural heritage—for example, describing garments like qipaos, ceremonial banners, or embroidered wall hangings. It appears more frequently in written or formal spoken Chinese than in casual daily speech, where simpler terms like 丝绸 (sī chóu) or just 绸 may suffice. Unlike generic fabric terms such as 棉布 (cotton cloth), 绸布 carries connotations of refinement, seasonal suitability (especially for spring/autumn wear), and artisanal value.
