Abstract
Abstract Tissue-type paper and nonwoven material are uniformly impregnated with a nonaqueous liquid carrier selected from liquid hydrocarbons, glycols and pine oils containing an agent uniformly distributed therein automatically, by applying a predetermined quantity of treating fluid to any portion of the nontreated material. The agent is selected from waxes, silicones and materials producing a predetermined odor. The agent does not separate from the carrier until at least the treated material is substantially impregnated, and the carrier and agent remain in the material substantially as when it was impregnated and are deposited in the same proportions as a thin film on a surface wiped by the material.
