Abstract

Abstract An apparatus is disclosed for treating cotton with dry steam to reduce the byssinotic effect thereof which comprises means for progressively moving cotton through a treatment zone in a compressed peripherally confined condition from an inlet end thereof to a discharge end thereof by progressively compressing a substantially continuous supply of cotton in generally loose form into the inlet end of the zone while progressively loosening and conveying away compressed cotton from the discharge end of the zone and means for continuously passing dry steam through the compressed peripherally confined cotton progressively moving through the treatment zone at a temperature and for a time period sufficient for the cotton to reach at least approximately 100* C without appreciably wetting the same before moving from the treatment zone.
