Embodiment 1

[0181] This example illustrates the use of a direct offset rotogravure printing machine to prepare a two-piece bath towel with a reinforcing agent on the inner surface.

[0182] The reagent used to prepare the fluidization enhancer is acrylic latex with a solid content of 45% (Rhoplex NW-2744F emulsion) obtained from Rohm & Hass Company in Philadelphia, Pennsylvania.

[0183] Mix 50% acrylic latex and 50% tap water to obtain a latex with a solid content of 23% to prepare a fluidized enhancer. Then, the fluidizing agent is put into the gravure printing groove, so that the fluidizing enhancer fills the recessed area of ​​the rotary gravure cylinder.

[0184]The surface of the gravure cylinder is coated with alumina ceramics, and the recessed areas are carved into the alumina ceramics by laser technology. The recessed areas are hemispherical, each with a diameter of 55μ and a depth of about 228μ. The pattern of the recessed areas is hexagonal, and its occurrence rate is 137.8 per lin...

[0193] This example illustrates the use of a direct offset rotogravure printing machine to prepare two sheets of bath towel paper with a reinforcing agent on the inner surfaces of the two sheets.

[0194] The reagent used to prepare the fluidization enhancer is acrylic latex (Rhoplex NW-1845 emulsion) with a solid content of 44% obtained from Rohm&Hass Company in Philadelphia, Pennsylvania.

Abstract

Strong and soft multi-ply tissue paper products useful as absorbent sanitary products such as bath tissue, facial tissue, and absorbent towels are disclosed. At least one internal surface of the tissue paper product has a surface deposited strengthening agent.

Description

Technical field [0001] In summary, the present invention relates to tissue paper products. More specifically, the present invention relates to tissue paper products coated with a reinforcing agent. Background of the invention [0002] Hygienic tissue products have been widely used. These products are supplied to the market in various specifications for various purposes such as facial tissues, toilet paper and hygroscopic paper towels. [0003] A common requirement for all these sanitary products is to have both strength and softness. Softness is a comprehensive tactile sensation produced when a paper product rubs the skin. The purpose of softness is to use these products to clean the skin without causing irritation. [0004] Those of ordinary skill in the art believe that one of the most important physical properties related to softness is product strength. Strength is the ability of the product and the paper web it constitutes to maintain physical integrit...
