Two pages from Posselt's Textile Journal, April 1919, on the construction of clay worsted twill cloth. The article works out how many ends and picks per inch give a well-built 3-and-3 six-end twill, using yarn diameters, a proportion rule for twill versus plain weave, and a 60° warp bend angle to account for lustre. The first page also gives weave diagrams (Figs. 3-5) with fabric particulars for a bold twill and two 3-and-2 warp rib patterns. Two short silk market news items (spot silk, broad silk orders) share the pages.
