Tissue sheets containing multiple polysiloxanes and having regions of varying hydrophobicity
View Patent ↗Hydrophilic polysiloxanes and hydrophobic polysiloxanes are used in combination to provide tissues, such as facial and bath tissues, with an optimal combination of absorbency and softness. At least one of the hydrophobic and hydrophilic polysiloxanes is applied to the outer surface of the tissue product in a zoned pattern such that the absorbent rate of the tissue varies across the surface.
1. A tissue product comprising one or more plies of cellulose papermaking fibers and having two outer surfaces, said product further comprising a hydrophilic polysiloxane and a hydrophobic polysiloxane, at least one of which is positioned within the product in a zoned pattern having a macroscopically discernable variation in the distribution of said at least one polysiloxane such that the absorbent rate varies across at least one outer surface of the product as determined by the Ten Water Drop Test, wherein the hydrophilic polysiloxane is uniformly distributed on at least one outer surface of the product and the hydrophobic polysiloxane is distributed in a macroscopically zoned pattern on the same surface of the product.
2. A tissue product comprising one or more plies of cellulose papermaking fibers and having two outer surfaces, said product further comprising a hydrophilic polysiloxane and a hydrophobic polysiloxane, at least one of which is positioned within the product in a zoned pattern having a macroscopically discernable variation in the distribution of said at least one polysiloxane such that the absorbent rate varies across at least one outer surface of the product as determined by the Ten Water Drop Test, wherein the hydrophobic polysiloxane is uniformly distributed on at least one outer surface of the product and the hydrophilic polysiloxane is distributed in a macroscopically zoned pattern on the same surface of the product.
3. A tissue product comprising one or more plies of cellulose papermaking fibers and having two outer surfaces, said product further comprising a hydrophilic polysiloxane and a hydrophobic polysiloxane, at least one of which is positioned within the product in a zoned pattern having a macroscopically discernable variation in the distribution of said at least one polysiloxane such that the absorbent rate varies across at least one outer surface of the product as determined by the Ten Water Drop Test, wherein both the hydrophobic polysiloxane and the hydrophilic polysiloxane are positioned on one or both outer surfaces in striped patterns, and further wherein the hydrophilic polysiloxane stripes are offset from the hydrophobic polysiloxane stripes.
4. A tissue product comprising one or more plies of cellulose papermaking fibers and having two outer surfaces, said product further comprising a hydrophilic polysiloxane and a hydrophobic polysiloxane, at least one of which is positioned within the product in a zoned pattern having a macroscopically discernable variation in the distribution of said at least one polysiloxane such that the absorbent rate varies across at least one outer surface of the product as determined by the Ten Water Drop Test, wherein the hydrophilic polysiloxane is distributed in a dot pattern and the hydrophilic polysiloxane is distributed in a stripe pattern.
5. A tissue product comprising one or more plies of cellulose papermaking fibers and having two outer surfaces, said product further comprising a hydrophilic polysiloxane and a hydrophobic polysiloxane, at least one of which is positioned within the product in a zoned pattern having a macroscopically discernable variation in the distribution of said at least one polysiloxane such that the absorbent rate varies across at least one outer surface of the product as determined by the Ten Water Drop Test, wherein the hydrophilic polysiloxane is distributed in a stripe pattern and the hydrophobic polysiloxane is distributed in a distinct spaced-apart element pattern.
