The properties studied included dimensional change, fabric deformation, seam puchering, stiffness, moisture regain, and bagging tendency. The only relatively large change in any of these properties which was brought about by changes in humidity was the rather large increase in stiffness which took place in high humidity. This has been attributed to a jamming of the structure due to the swelling of the fivers, and was apparently not related to the type of fiber which was blended with the wool.
