The technical testing of yarns and textile fabrics
A technical manual published in London in 1920 by Scott, Greenwood, written by J. Herzfeld and David Thomas Nisbet for textile engineers and testing staff. Its engravings show laboratory apparatus for measuring yarn and fabric, drawn in precise line with lettered parts and figure captions. A designer might borrow the crisp mechanical linework, dial faces, and reel frames as period industrial detail.
