Embodiment 1

[0233] This example illustrates the use of an offset rotogravure press to produce a two-ply bath tissue with a uniform, discrete deposit of directly immobilized chemical softener.

[0234] The reagents to prepare a soft solution are:

[0235] 1. Tallow diester chloride quaternary ammonium salt (ADOGEN SDMC) available from WITCO Chemical Company of Greenwich, CT.

[0236] 2. Polyethylene glycol 400 available from J.T. Baker Company of Phillipsburg, NJ.

[0237] 3. Isostearic acid (Century 1105, available from Union Camp, Wayne, NJ).

[0238] Melt and stir 75% tallow diester chloride quaternary ammonium salt, 20% polyethylene glycol 400, and 5% isostearic acid in a 140°F thermostatic vessel to make a soft solution, which is then loaded into a gravure tank , so that the softening solution fills the recessed area of ​​the rotogravure cylinder.

[0239] The gravure cylinder structure included a central void for circulation of heated fluid to maintain the roll surface temperature...

[0251] 3. Isostearic acid (Century 1105, available from Union Camp, Wayne, NJ).

[0252] 4. Amodimethicone (SF1921, available from GE Silicones of Waterford, NY).

[0253] Melt and stir 33.8% tallow diester chloride quaternary ammonium salt, 9% polyethylene glycol 400, 2.3% isostearic acid, and 55% SF1921 in a 140°F thermostatic vessel to make a soft solution, then fill On the gravure tank, the soft solution fills the recessed area of ​​the rotogravure cylinder.

[0266] 3. Isostearic acid (Century 1105, available from Union Camp, Wayne, NJ).

[0267] A soft solution was prepared by melting and stirring 76% tallow diester chloride quat, 20% polyethylene glycol 400, and 4% isostearic acid in a 140°F thermostatic vessel, then loaded onto the gravure tank , so that the softening solution fills the recessed area of ​​the rotogravure cylinder.

[0268] The gravure cylinder structure included a central void for circulation of heated fluid to maintain the roll surface temperature at 140°F. ...

Abstract

The present invention discloses high strength, softness and low dusting tissue webs for use in the manufacture of soft, absorbent tissue products such as bath tissue, facial tissue and absorbent towels. The tissue has a uniform, discrete deposit of directly fixed chemical softener on at least one surface.

Description

technical field [0001] In general, the present invention relates to tissue paper products. More particularly, the present invention relates to tissue paper products containing chemical softeners. Background of the invention [0002] Hygienic tissue paper products are widely used. These products are supplied in the market in various sizes for various applications such as facial tissue, toilet tissue and absorbent paper toweling. [0003] All these hygienic products are designed to meet a common need, especially that it should be soft to the touch. Softness is a comprehensive tactile sensation produced by a paper product when it rubs against the skin. The purpose of the softness is that these products can be used to clean the skin without causing irritation. Effectively cleansing the skin is a long-standing personal hygiene issue for many people. Provided convenient and thorough washing, eg, with soap and copious amounts of water, usually does not...
