ABSTRACT:
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.
