    &#65533;&#65533;I*
    Une masse lâche de fibres de polyamides est traitée pendant quelques secondes à l'aide de chlore gazeux dilué. Pour la dilution on mélange 9 parties d'air atmosphérique avec une partie de gaz de chlore. Immédiatement après ^La masse devenue quelque peu collante est oalandrée à température ordinaire . Le produit plat
