Abstract
A softener composition comprises a mixture of (A) a mono(long-chain) quaternary ammonium salt such as monotallowalkyl trimethyl ammonium chloride, (B) a di(long-chain) quaternary ammonium salt such as ditallowalkyl dimethyl ammonium chloride and (C) a tri(long-chain) quaternary ammonium salt such as tritallowalkyl monomethyl ammonium chloride), the weight ratio of the components (A):(B):(C) falling within the range of from 2 to 30: 96 to 50: 2 to 20, and iodine value of the mixture being in the range of 35 to 100; and (D) a polyoxyethylene adducted nonionic surfactant such as polyoxyethylene octylphenyl ether (P=40). The softener composition improves the softness of natural fibers without impairing the water absorption properties thereof. It also improves the softness of chemical fibers and gives them excellent antistatic property.
