✦ Synopsis

CURRENT TOPICS 33I

Bast fibers and hemp showed breakdown into individual fibers in 30 seconds and into fibrillae with diameters below 0.1 micron in 30 minutes. Jute showed extensive lengthwise splitting. Cotton fibers were torn apart in a few seconds, some appearing to be exploded from the inside by air enclosed in the lumen. Ordinary viscose rayon showed tears at right angles to the fiber axis but higher oriented, hollow viscose fibers showed lengthwise fiber splitting. Raw silk was partially degummed in 10 minutes' exposure. Wool was resistant to damage and even prolonged exposure merely removed some scales; however, in previously damaged wool, scales were removed rapidly. Hair was torn after 30 minutes, Perlon was extremely resistant.

In fabrics, the structure of yarns was first loosened, then the fibers were attacked to a degree close to that in the fiber form. Fabrics were resistant to damage at exposures up to two hours, with the exception of linen, which showed damage relatively soon.
