Process and apparatus for treating fibres with ozone-steam mixtures.

摘要

Pieces of fabric 30 are treated with ozone-steam mixtures by conveying them by means of a conveyor 19 through an open-ended chamber 10 having a horizontal middle section 10a substantially elevated with respect to the open chamber ends 10b and to which ozone and steam are centrally introduced through inlets 11, 12. The elevation of the middle section 10a is found to confine the ozone and steam to this section with little loss at the ends. The apparatus includes circulating fans 13, tubes 15 for withdrawal of gaseous mixture for analysis and also an outlet tube 23 for condensed water.
