An 1898 French technical treatise by André Simon analyzing the principal woven fabrics by their interlacement of warp and weft, with 219 original figures placed in the text. It is organized in three groups: fabrics with straight threads, pile fabrics (velvets), and gauze fabrics with twisted threads. Chapters cover loom parts, drafting and threading (rentrage, empoutage), plain, twill and satin weaves, double cloth, piqué and matelassé, pleated fabrics, brocading, bead fabrics, warp and weft velvets, leno-type gauzes, and chenille. Many pages carry drawdowns, threading diagrams and mechanism drawings for hand looms, dobby and Jacquard harnesses.
