SHRINKPROOFING OF ANIMAL FIBERS BY PASSING SAID THROUGH AN ELECTRICAL DISCHARGE ZONE CONTAINING OZONE

摘要

Proteinous animal fibers are rendered shrinkproof by passing said directly through a high-voltage electrical discharge ozone-generating zone which is at atmospheric pressure and open to the atmosphere. The dyeing properties of the fiber are unaffected by the treatment. Apparatus embodying both planar and curved discharge zones are described.
