Title: Water repellency illustration
Date(s): 1955

Not only is the design attractive in itself but it clearly shows the practicability of a water repellent treatment. Material processed with DuPont Aridex or Zelan durable repellent will give protection against rain and other non fatty liquids, without affecting in any way the nature of the fabrics to which they have been applied.
