An article from the trade journal Textiles that explains the basic units of length, area and weight used in textile calculations and the systems for numbering yarn. It contrasts fixed-weight systems (cotton, worsted, woolen, linen, with yards per pound) with fixed-length systems (silk deniers and drams, jute). It covers ply notation, including the exception for spun silk, and has tables of the principal yarn-count standards. The page ends with an unrelated item on English import licenses.
