A 1929 article from The Melliand giving guidance on washing artificial silk (rayon) garments. It explains how the fibre loses strength when wet and is sensitive to caustic alkalis and soda. It compares soap flakes and powders such as Lux, Perflor and Persil, recommends washing at 30-35 °C, corrects common advice such as cold-water washing and vinegar rinses, and ends with short general washing and ironing directions.
