The concluding part of Franz Müller's article on weave-structure and material effects in rayon (Kunstseide) fabrics. It discusses block-type binding effects where warp and weft color stripes cross in plain weave, and how jacquard figures change binding (e.g., satin figure on plain ground, twill on satin ground). It also covers the fragility of rayon warps, low warp densities, the use of unplied rayon, and rayon's prospects for replacing natural silk. Figures show binding diagrams and fabric samples. The scan begins with the end of an unrelated piece on standardizing jacquard machines, cylinders and punched cards.
