4. Wash in hot water. 5. Scour at room temperature for 30 min in 1% sodium metabisulfite solution. 6. Wash. When dried, the strip of leaf rolls in from both edges and becomes a smooth semitransparent thread which is strong, elastic, and quite waterproof. The fiber has a fairly light yellow color after the bleaching step and the bisulfite treatment improves it considerably. This bath will process about 400 lb of fiber. |
