Abstract

Relationship between hydrophobicity of dyes and affinity onto pure polypropylene fibers has been analyzed by using the molecular descriptor as a method to predict chemical and physical characteristics of compounds. Hydrophobicity of newly synthesized red dyes calculated by LogP which is one of molecular descriptors was increased continuously as the length of alkyl substituents increased. The dyeability onto polypropylene fibers was increased as LogP of the dyes increased and was very high when the hydrophobicity is over 6.
