Estimating the term…
Paper products treated on two surfaces with a liquid resistant composition are disclosed. The paper products can be, for instance, bath tissues, facial tissues, paper towels, and industrial wipers. The liquid resistant compositions can include any additive that provides benefits to the product. For instance, the liquid resistant composition can be a softener containing a hydrophobic additive. In one embodiment, the hydrophobic additive is a polysiloxane. In accordance with the present invention, the water resistant composition is applied to each surface according to a pattern. Each of the patterns includes treated and untreated areas. The patterns are positioned on the paper product such that untreated areas on one surface are in correspondence with the treated areas on the other surface of the sheet.
A paper product comprising:
A paper product comprising:
A tissue product comprising:
A process for making a tissue product having improved strikethrough and absorbent properties, said process comprising the steps of supplying a tissue sheet having a bulk of greater than about 2 cm2/g and comprising one or more plies and treating said tissue sheet with a water resistant chemical additive such that the water resistant chemical additive is applied to the first side of the paper sheet according to a first pattern and applied to the second side of the paper sheet according to a second pattern, the water resistant chemical additive comprising a material selected from the group consisting of a softener, a lotion, a skin-conditioning agent, a sunscreen agent, an anti-acne agent, an anti-microbial agent, a cosmetic astringent, an emollient, an anti-friction agent, a debonder, an antifungal agent, a sizing agent, an antiseptic agent, a drug astringent, an external analgesics, a skin exfoliating agent, a skin protectant, and mixtures thereof the first pattern covering from about 50% to about 99% of the surface area of the first side of the sheet and the second pattern covering from about 50% to about 99% of the surface area of the second side of the sheet, each of the patterns including non-treated areas and treated areas, and wherein the patterns are applied to the sheet in an offset relationship such that the non-treated areas applied to one side of the sheet are located opposite treated areas on the other side of the sheet.
A process of making a multi-ply tissue product of 3 or more plies having improved strikethrough and absorbent properties, said process comprising the steps of 1) supplying multiple plies of a first tissue sheet having a bulk of greater than about 2 cm2/g, said tissue sheet being treated with a water resistant chemical additive such that from about 50% to about 99% of the surface area of the sheet is treated with the water resistant chemical such that the sheet contains treated and untreated areas and 2) arranging the plies in a manner such the treated and untreated regions of the nearest adjacent treated ply or plies are arranged in an offset relationship such that the non-treated areas of a treated ply are located opposite treated areas on the nearest adjacent treated ply or plies.
