A 1900 installment of a series in Engineering on textile machinery at the Paris Exhibition. It introduces fabric classification by structure, sorting tissues into eight classes: plain loom weaving, gauze, Jacquard brocade, tulle, lace, knotted-pile, netting, and knitted loop structures. It then explains basic weave notation, covering warp and weft, pattern squares, and the linen, twill, serge and satin sequences. Diagrams show gauze, tulle, loop structures and simple pattern grids.
