New Insulating Materials Cut Jet Heat and Cold Loss
Four new insulating materials are reported by the American Institute of Chemical Engineers. One shields jet plane tails from exhaust heat while three function at low temperatures. They range from a sand like product to a foam eight to ten times lighter than cork. Blankets of sand protected planes and crew from jet exhaust. The substance, called

Rayon Dye Process Revealed
Viscose rayon fibers absorb dye non uniformly with the core taking up dye faster and losing it more quickly than the skin. In tests with Solo phenyl Fast Blue Green BL the core colored first while the skin remained pale until Victoria Blue penetrated both core and skin.
Dyeing process details for viscose rayon fibers
The text describes an experiment where fibers absorb dye, are washed with alcohol to bleed out excess dye, and dried before significant loss from the skin. An end-on view of the fibers was photographed. Dr. P. H. Hermans led the preparation, with full staining details in the Textile Research Journal.
