Aramid and aramid-blend fabrics are dyed or flame-retardant treated or both dyed and flame-retardant treated using conventional heat dyeing equipment. Octylpyrrolidones, tributyl phosphine oxide and mixtures of N-cyclohexyl-2-pyrrolidone with available dye carriers are used as diffusion-promoting agents for dyes, flame retardant agents or both. Odor-free, flame resistant, colored or colored and highly flame resistant products result.
Des tissus d'aramides ou de mélanges d'aramides sont teintés ou soumis à un traitement d'ignifugation, ou les deux, à l'aide d'un équipement de teinture à chaud traditionnel. Des octylpyrrolidones, de l'oxyde de phosphine tributyle et des mélanges de N-cyclohexyl-2-pyrrolidone ainsi que des véhiculeurs de teinture disponibles sont utilisés comme agents favorisant la diffusion pour les teintures, les agents ignifuges ou les deux. L'on obtient ainsi des produits inodores, ignifuges, colorés ou des produits colorés et possédant une excellente résistance au feu.
