The present invention relates to specific compositions made by the sulfation of alkoxylated crude guerbet alcohol mixtures that contain between 15% and 50% lower molecular weight alkoxylated alcohols. The lower molecular weight alcohols are the raw material alcohols used to make the guerbet. Sulfated compositions made from this specific bi-modal distribution have unique emulsification properties and experience minimal chromatographic separation when used in downhole applications.

Bi-modal Guerbet alkoxy sulfate surfactants

An ultra soft, bulky, multi-ply tissue having low overall sidedness and a geometric mean tensile strength of less than about 800 g/3&#x2033; wherein an embossed ply has a TMI sidedness of at least about 0.45 and an embossed area of at least about 2%, which is capable of being made from non-premium furnish, and method for making such products are disclosed. An ultra soft, bulky, multi-ply tissue having low overall sidedness and a geometric mean tensile strength of less than about 35 g/3&#x2033; per lb. of basis weight wherein an embossed ply has a TMI sidedness of at least about 0.45 and an embossed area of at least about 2%, which is capable of being made from non-premium furnish, and method for making such products are also disclosed.

Soft bulky multi-ply product

A process for the manufacture of single-ply, absorbent paper product, printed on before or after embossing on the Yankee side, air side, or both sides, having a serpentine configuration; low sidedness; a basis weight of at least about 12.5 lbs. per 3000 square foot ream; a specific total tensile strength between 40 and 200 g/3 inches/lb per 3000 square foot ream; a cross direction specific wet tensile strength between 2.75 and 20.0 g/3 inches/lb per 3000 square foot ream; an MD tensile to CD tensile ratio between 1.25 and 2.75; a specific geometric mean tensile stiffness between 0.5 and 3.2 g/inch/% strain per pound per 3000 square foot ream; a friction deviation of less than 0.250; a sidedness parameter of less than 0.30; and a printed sidedness value of &Dgr;E of less than 2.

Printed, soft, bulky single-ply absorbent paper having a serpentine configuration and low sidedness and methods for its manufacture

The present invention relates to specific compositions made by alkoxylation of crude guerbet alcohol mixtures that contain between 15% and 50% lower molecular weight alkoxylated alcohols. The lower molecular weight alcohols are the raw material alcohols used to make the guerbet. Compositions containing this specific bi-modal distribution have unique emulsification properties.

The present invention is an ultra soft, multi-ply tissue made from non-premium furnish using wet press technology.

The present invention is a method of making an ultra soft, multi-ply tissue from non-premium furnish using wet press technology and the product produced thereby.

The present invention relates to a soft, thick, single-ply, printed, absorbent paper product having a Yankee side and an air side wherein the absorbent paper is printed on before or after embossing on the Yankee side, air side, or both sides, said absorbent paper exhibiting a serpentine configuration. This inventions also relates to a process for the manufacture of such absorbent paper product having a basis weight of at least about 12.5 lbs. per 3000 square foot ream and having low sidedness, said tissue exhibiting: a specific total tensile strength of between 40 and 200 grams per 3 inches per pound per 3000 square foot ream, a cross direction specific wet tensile strength of between 2.75 and 20.0 grams per 3 inches per pound per 3000 square foot ream, the ratio of MD tensile to CD tensile of between 1.25 and 2.75, a specific geometric mean tensile stiffness of between 0.5 and 3.2 grams per inch per percent strain per pound per 3000 square foot ream, a friction deviation of less than 0.250, and a sidedness parameter of less than 0.30. These single-ply, printed, absorbent paper products in the form of unembossed or embossed single-ply bathroom tissue, facial tissue, or napkin are useful articles of commerce. The single-ply absorbent paper products exhibit a printed sidedness value of &Dgr;E of less than 2.

Printed, soft, bulky single-ply absorbent paper having a serpentine configuration and low sidedness

A method of adding materials to a web is disclosed. The method includes mixing a material into an air supply for an air knife, directing the air knife onto a surface of at least one of a pair of embossing rolls, and passing a paper web between the pair of embossing rolls. The embossing rolls coat at least one surface of the paper web with the material on the surface of the at least one embossing roll.

Web embossing method

A method of cleaning an embossing roll used in an embossing process. The method includes steps of passing a paper web between a pair of embossing rolls and preventing or cleaning deposits from the surface of at least one embossing roll. Pressurized air is forced through an air nozzle having an elongated narrow outlet that directs the pressurized air as an air knife against the patterned surface of the embossing roll after the patterned surface rotates out of contact with the web. The air knife extends an embossing width of the embossing roll. A lubricant or solvent may be mixed with the pressurized air.

Method of embossing a web and cleaning deposits from embossing roll

An embossing roll cleaning apparatus is provided. The cleaning apparatus includes a nozzle having an air inlet and an elongated narrow outlet that extends an embossing width of the embossing roll. A source of compressed air is connected to the air inlet of the nozzle. The outlet of the nozzle directs the pressured air as an air knife against the surface of the embossing roll to dislodge deposits stuck to the surface of the embossing roll.

Embossing roll cleaning apparatus

The present invention relates to a soft, thick, single-ply, printed, absorbent paper product having a Yankee side and an air side wherein the absorbent paper is printed on before or after embossing on the Yankee side, air side, or both sides, said absorbent paper exhibiting a serpentine configuration. This inventions also relates to a process for the manufacture of such absorbent paper product having a basis weight of at least about 12.5 lbs. per 3000 square foot ream and having low sidedness, said tissue exhibiting:

Printed, soft, bulky single-ply absorbent paper having a serpentine

A method is provided for cleaning a surface of an embossing roll in which the surface of the embossing roll is cleaned by directing pressurized air through an air nozzle as the embossing roll rotates. The air nozzle directs the pressurized air as an air knife that extends for the width of the embossing roll to clean the surface. A lubricant and solvent solution may be added to the air supply of the air nozzle to prevent deposits from sticking to the surface of the embossing roll and to dissolve any deposits that do stick to the surface of the embossing roll.
