Abstract
A composition for dyeing material of synthetic aromatic polyamide fibers, including a cationic dye and a dye assistant, which is a mixture of N-substituted phthalimide and an emulsifier. The N-substituted phthalimide is preferably a 2:1 mole ratio of N-butyl phthalimide and isopropyl phthalimide. The emulsifier is preferably propylene oxide and ethylene oxide block polymer, and an anionic surfactant blend and an anionic/cationic surfactant blend.
Claims9
A composition for dyeing material of synthetic aromatic polyamide fibers, comprising a cationic dye and a dye assistant, said dye assistant being a mixture of N-substituted phthalimide selected from the group consisting of N-butyl phthalimide, N-isopropyl phthalimide, N-ethyl phthalimide, N-isobutyl phthalimide, N-2-ethyl-hexyl phthalimide, N-ethoxymethyl phthalimide, N-propoxymethyl phthalimide, and N-methyl carbonyl-N-methexyl phthalimide and an emulsifier selected from the group consisting of the mixture of a propylene oxide and ethylene oxide block polymer and a surfactant, the mixture of oxyalkylated alkyl alcohol, oxyalkylated phenolic resin and an ethoxylated alkyl phosphate ester, the mixture of isopropylamine salt of dodecyl benzene sulfonic acid and ethoxylated nonyl phenol, the mixture of isopropylamine salt of dodecyl benzene sulfonic acid and ethoxylated soya amine, and a mixture of isopropylamine salt of dodecyl benzene sulfonic acid and ethoxylated castor oil.
