A two-page installment from the trade journal Textiles in a series on air moistening in textile mills. It presents a chart of daily moisture regain for silk in process of manufacture for September to November, based on Schloesing's tables and U.S. Weather Bureau observations for New York in 1917-18. It also gives a full table of moisture regain for wool at 54°, 75° and 95° F across relative humidity of 1 to 95 percent, with comments on how humidity and temperature affect regain.
