... sturdy, closely woven, high-count sheeting. The close weave gives good cutting, and the heavy threads provide good coloring. Buffing is usually done in two operations. The first, the cutting-down operation, is done with a sewn buffing wheel operating at a surface speed of 40 to 45 m/s (8000 to 9000 sfm...
