Uninked Ribbon Fabric: Nylon with a Crimped Filler, Relaxed in Soap (Thompson, US 2,918,160, 1959)
Nylon ribbons wear well but hold little ink; cotton holds more but frays under the type. Thompson wove nylon with a crimped filler held taut; relaxed after weaving, the crimped filaments spring apart into tiny pockets that store ink, while the surface stays flat.
Result: a thin nylon ribbon fabric, about 167 x 100 per inch, that held ink for about twice as many lines.

Scour, then cut into ribbon widths with the crimped yarn running across the ribbon. A heated cutter seals the edges. Finished count about 167 x 100; a filler of 95-110 per inch works.
