Description

BACKGROUND

The tissue industry has long had a long-felt need for a very high decaying temporary wet strength agent. Poor decay translates into the clogging of pipes and septic systems. While many consumers desire wet strength in their tissue, there are consumers who do not use tissue with a temporary wet strength agent due to this problem. A tissue with high initial wet strength and outstanding decay would have a very significant benefit for consumers.
The tissue industry has also had a long-felt need for a temporary wet strength agent that can exhibits very high initial wet tensile. Having a composition that would achieve this objective would allow the paper-maker to use low dosages of this temporary wet strength agent and still achieve acceptable decay resulting in significant cost savings. Having a composition that produces tissue that exhibits both high decay and a high initial wet strength would provide numerous benefits to both consumers and papermakers.
Unfortunately, current known temporary wet strength agents have not been able to provide a temporary wet strength agent that is high decaying and that exhibits a very high initial wet tensile. U.S. Pat. No. 6,548,427, for instance, teaches the addition of a temporary wet strength agent, such as glyoxylated polyacrylamide, to a tissue product during the wet end of a tissue manufacturing process and the subsequent addition of an alkaline reagent to the tissue product during the dry end of the manufacturing process. The patent does not provide meaningful guidelines to enable one or ordinary skill in the art to make a tissue with high initial wet strength and outstanding decay. The use of sodium bicarbonate, discussed in Example 2 of U.S. Pat. No. 6,548,427, for instance, has been found to be inadequate in producing a tissue with high initial wet strength and outstanding decay. This patent does not teach how users in the field can achieve a tissue product having very high decaying temporary wet strength agent, let alone a tissue product having an immediate wet tensile strength of at least 90% of the wet strength as compared to a web that does not contain a degrading agent and a wet soak decay that is at least a ten point improvement as compared to a tissue fibrous web that does not contain a degrading agent.
For the foregoing reasons, there is a need to develop a tissue product that exhibits improved decay.
For the foregoing reasons, there is a need to develop a tissue product that exhibits an immediate wet tensile strength of at least 90% as compared to the immediate wet tensile strength of a web that does not contain a degrading agent.
For the foregoing reasons, there is a need to develop a tissue product that exhibits a wet soak decay that is at least a ten point improvement as compared to a tissue fibrous web that does not contain a degrading agent.

DESCRIPTION

The invention relates to a tissue product that includes (a) a tissue fibrous web incorporated throughout the tissue product; (b) a temporary wet strength agent capable of forming hemi-acetal bonds with the fibers of the web to prevent immediate degradation of the web when the tissue product contacts water; and (c) a composition containing a degrading agent selected from the group consisting of alkaline agents, oxidizing agents, nucleophilic agents, and combinations thereof.
The degrading agent is located throughout the fibrous web and the degrading agent is present throughout the tissue product in an amount that is sufficient to make the fibrous web exhibit (i) an immediate wet tensile strength of at least 90% of the wet strength as compared to a web that does not contain a degrading agent and (ii) a wet soak decay that is at least a ten point improvement as compared to a tissue fibrous web that does not contain a degrading agent.
The invention is based on the discovery that by using a certain composition containing a degrading agent at the “wet end” of a papermaking process, it is now possible to make a tissue having a highly useful combination of properties, namely (i) an immediate wet tensile strength of at least 90% of the wet strength as compared to a web that does not contain the degrading agent and (ii) a wet soak decay that is at least a ten point improvement as compared to a tissue fibrous web that does not contain the degrading agent. The phrase “a ten point improvement,” refers to the difference between the initial wet tensile and thirty minute wet soak tensile as a percentage of initial wet tensile is at least ten full points or greater using the invented technology, e.g., 80% vs. 70% wet tensile decay in thirty minutes. The phrase “the water drop test” refers to the time, measured in seconds, for a 5 microliter drop of water to absorb into a sheet of paper.
Other than in the operating examples or where otherwise indicated, all numbers or expressions referring to quantities of ingredients, reaction conditions, and the like, used in the specification and claims are to be understood as modified in all instances by the term “about.” Various numerical ranges are disclosed in this patent application. Because these ranges are continuous, they include every value between the minimum and maximum values. Unless expressly indicated otherwise, the various numerical ranges specified in this application are approximations.
The temporary wet strength suitable for the invention can be any temporary wet strength agent capable of forming hemi-acetal bonds with the fibers of the web to provide initial wet strength in the fibrous sheet and to prevent immediate degradation of the web when the tissue product contacts water. The temporary wet strength agent provides initial wet strength in the fibrous sheet. The temporary wet strength agent component, for instance, can be selected from the group of the following temporary wet strength agents: dialdehyde starches, glyoxylated polyacrylamides, and combinations thereof. In one embodiment, the temporary wet strength agent is a glyoxylated polyacrylamide having a backbone that is less than 10,000 daltons prior to glyoxylation.
The amount of the temporary wet strength agent can vary, depending on the application. In one embodiment, the temporary wet strength agent is in an amount that is at least 0.05 wt %, based on the weight of the dry fiber. In another embodiment, the temporary wet strength agent is in an amount that is at least 0.1 wt %, based on the weight of the dry fiber. In another embodiment, the temporary wet strength agent is present in an amount ranging from 0.05 to 1.0 wt %, based on the weight of the dry fiber.
The composition containing the degrading agent is specifically designed to be used to make tissue products having a combination of useful immediate wet tensile strength and wet soak decay properties. In one embodiment, the composition containing the degrading agent includes a charged moiety including (1) a core component selected from the group consisting of alkaline agents, oxidizing agents, nucleophilic agents, and combinations thereof and (2) a charged coating that surrounds at least a portion of the core component. The charged moiety can be cationically charged or anionically charged. As such, the invention can encompass a degrading agent component includes an anionically charged or a cationically charged moiety including a core alkaline, oxidizing, or nucleophilic component and an anionically charged (or cationically charged) coating covering at least a portion of the core alkaline, oxidizing, or nucleophilic component.
The cationically charged coating is generally a surfactant having an HLB value that is >3. A useful cationic surfactant coating includes solid quaternary ammonium compounds. The anionically charged coating may be made from materials such as solid carboxylic acid and/or sulfonic acid containing compounds.
The degrading agent must be capable of degrading the temporary wet strength agent-fiber bonds in a fibrous sheet. The degrading agent is generally selected from the group of alkaline agents, oxidizing agents, nucleophilic agents, and combinations thereof. Examples of suitable degrading agents include and are not limited to Mg(OH)₂, Ca(OH)₂, Mg(HSO₃)₂, MgO₂, ZnO, Na₂SO₃, (MgCO₃)₄.Mg(OH)₂, Na₂O.Al₂O₃, H₂O₂, and combinations thereof. In one embodiment, the alkaline reagent component excludes sodium acetate, sodium benzoate, sodium carbonate, sodium bicarbonate, calcium carbonate, calcium bicarbonate, and combinations thereof.
In another embodiment, the composition containing the degradation component includes (a) a degrading agent selected from the group consisting of alkaline agents, oxidizing agents, nucleophilic agents, and combinations thereof; and (b) a degradation inhibitting carrier component. Such composition can be in various forms. For instance, the composition containing the degrading agent component includes (i) a liquid degradation inhibiting carrier and (ii) the degrading agent. In another embodiment, the degrading agent is a solid moiety suspended in liquid particles.
The degradation inhibitting carrier prevents the degrading agent from lowering the initial wet tensile such that the degradation inhibitting carrier delays the action of the degrading agent to yield high initial wet tensile and high decay. The degradation inhibitting carrier may be described as a hydrophobic carrier, e.g., a protective hydrophobic liquid vehicle, that allows the degrading agent to lower the wet soak tensile, thereby improving the decay.
The degradation inhibitting carrier, for instance, can include lotions that include mixtures containing materials selected from the following: water, mineral oil, petrolatum, sorbitol, stearic acid, lanolin, lanolin alcohol, cetyl alcohol, glyceryl stearate, PEG-100 stearate, triethanolamine, dimethicone, propylene glycol, microcrystalline wax, triethyl citrate, PPG-3 myristyl ether, disodium EDTA, methylparaben, ethylparaben, propyl-paraben, fragrance, xanthan gum, butylparaben, methyldibromo glutaronitrile. Lotions containing the following materials can also be used: a mixture of water, glycerin, sodium myristoyl sarcosina, PEG-120 methyl glucose dioleate, sodium lauroamphoacetate, disodium lauroampho-acetate, glycol distearate, PEG-150 pentaerithritol tetra stearate, sodium tridecethsulfate, polyquaternium-10, sodium laureth sulfate, phenoxy-ethanol, cocamide mea, citric acid, DADM hydantoin, disodium EDTA, laureth-10, fragrance. In one embodiment, a cream containing materials selected from the following can be used: a mixture of water, sodium C14-16 olefin sulfonate, cocamidopropyl betaine, cetyl alcohol, stearyl alcohol, di-C-12-15 alkyl fumarate, coco-glucoside, coconut alcohol, sodium methyl cocoyl taurate, DEA-cetyl phosphate, matriciaria (chamomilla recutita) flower extract, aloe barbadensis leaf extract, chamonile (anthemis nobiis) flower extract, hydroxypropyl methylcellulose, potato (sodium tuberosum) strach, propylene glycol, fragrance. In another embodiment, a cream containing the following materials can be used: a mixture of water, sodium cocoyl isethionate, propylene glycol, stearic acid, cetearyl alcohol, cocoamidopropyl betaine, hydroxypropyl methylcellulose, sodium lauroyl sarcosinate, salicylic acid, menthol, fragrance, magnesium aluminum silicate, disodium EDTA, methylparaben, propylparaben, DADM hydantonin, titanium dioxide (Cl 77891). Alternatively, the following materials may also be suitable: Tetra-alkyl ammonium chloride, quaternary amine tetra alkyl ammonium chloride, sodium dioctyl sulfosuccinate in petroleum distillate, polyoxyethylene(10) oleyl ether Polyoxyethylene(2) cetyl ether. Examples of commercially available materials can be selected from the group of Aerosol OT, Variquat K1215, Suave Cream, Neutragena Cream, Olay lotion, tissue softener, Brij 97, Brij 52, solid wax coatings, other such protective hydrophobic liquid vehicles, and combinations thereof.
The composition containing the degrading agent can be made by any suitable method that produces a composition containing suitable properties. The charged moiety can be made by mixing the core component and the anionic or cationic substrate under conditions that produce the charged coating. For instance, the charged coating material can be dissolved in a suitable solvent in which the particulate degrading agent is insoluble. The degrading agent is then slurried in this solution. The solvent is then stripped, thereby, depositing the coating onto the surface of the degrading agent. Alternatively, the coating and degrading agent can be milled together to form the coated degrading agent. Alternatively, the coating can be dissolved and precipitated onto the degrading agent or the materials can be co-precipitated provided the coating remains largely on the outside of the core degrading agent.
Alternatively, the composition can be made by combining the degrading agent with the degradation inhibiting carrier component under conditions that produce (i) a liquid degradation inhibiting carrier and (ii) the degrading agent or a degrading agent as a solid moiety suspended in liquid particles. For instance, materials such as Mg(OH)₂, Ca(OH)₂, Mg(HSO₃)₂, MgO₂, ZnO, Na₂SO₃, (MgCO₃)₄.Mg(OH)₂, Na₂O.Al₂O₃, H₂O₂, or combinations thereof either suspended, dissolved, or emulsified in lotions, Aerosol OT, Variquat K1215, Suave Cream, Neutragena Cream, Olay lotion, tissue softener, Brij 97, Brij 52, or combinations thereof. The temperatures at which a composition of the invention is made or used varies with application.
The pulp slurry that is treated with a composition of the invention generally includes any pulp slurry, which when used in accordance to the invention, produces tissue that exhibits improved initial wet tensile and decay. Suitable fibers provide sufficient sheet integrity to make tissue products suitable for their ordinary use. Papermaking fibers for making the tissue product webs of this invention, for instance, can include any natural or synthetic fibers suitable for the end use products listed above including, but not limited to: nonwood fibers, such as abaca, sabai grass, milkweed floss fibers, pineapple leaf fibers; softwood fibers, such as northern and southern softwood kraft fibers; hardwood fibers, such as eucalyptus, maple, birch, aspen, or the like. In addition, furnishes including recycled fibers may also be utilized. In making the tissue products, the fibers are formed into a pulp furnish by known pulp stock formation processes.
Softening agents, sometimes referred to as debonders, can be added to the tissue making process to enhance the softness of the tissue product. Such softening agents can be incorporated with the fibers before, during or after dispersing the fibers in the furnish. Such agents can also be sprayed or printed onto the web after formation, while wet, or added to the wet end of the tissue machine prior to formation. Suitable softening agents include, without limitation, fatty acids, waxes, quaternary ammonium salts, dimethyl dihydrogenated tallow ammonium chloride, quaternary ammonium methyl sulfate, carboxylated polyethylene, cocamide diethanol amine, coco betane, sodium lauryl sarcosinate, partly ethoxylated quaternary ammonium salt, distearyl dimethyl ammonium chloride, polysiloxanes and the like. Examples of suitable commercially available chemical softening agents include, without limitation, Berocell 596 and 584 (quaternary ammonium compounds) manufactured by Eka Nobel Inc., Adogen 442 (dimethyl dihydrogenated tallow ammonium chloride) manufactured by Sherex Chemical Company, Quasoft 203 (quaternary ammonium salt) manufactured by Quaker Chemical Company, and Arquad 2HT-75 (di(hydrogenated tallow) dimethyl ammonium chloride) manufactured by Akzo Chemical Company. Suitable amounts of softening agents will vary greatly with the species of pulp selected and the desired characteristics of the resulting tissue product. Such amounts can be, without limitation, from 0.05 to 1 weight percent based on the weight of fiber, more specifically from 0.25 to 0.75 weight percent, and still more specifically 0.5 weight percent.
The tissue pulp slurry generally does not contain an appreciable amount of permanent wet strength agent. In one embodiment, the pulp slurry contains a permanent wet strength resin in an amount that is less than 250 ppm. In another embodiment, the pulp slurry contains a permanent wet strength resin in an amount that is less than 100 ppm. In another embodiment, the pulp slurry does not contain any permanent wet strength resin.
In use, the invention provides a highly effective method for making paper having a combination of highly useful properties. The temporary wet strength agent and the composition containing a degrading agent are added to the wet end of a papermaking process such that the degrading agent is retained in the final sheet. The order of addition of the temporary wet strength agent and the degradation composition is not important. As such, the invention is useful in a process for forming a tissue product from a tissue fibrous web, such that the invention provides an improvement that involves the addition to the wet-end of the tissue product forming process of a composition containing a degrading agent selected from the group consisting of alkaline agents, oxidizing agents, nucleophilic agents, and combinations thereof.
One way that such a method may be practiced includes a method that involves the steps of (a) adding to a tissue pulp slurry a composition comprising: (1) a temporary wet strength agent component capable of forming hemi-acetal bonds with the fibers of a tissue web to provide initial wet strength and subsequent rapid degradation of the initial wet strength when the tissue web contacts water, the temporary wet strength agent being present in an amount ranging from 0.05 to 1.0 wt %, based on the weight of the dry fiber; (2) adding to a tissue pulp slurry, a composition containing a degrading agent selected from the group consisting of alkaline agents, oxidizing agents, nucleophilic agents, and combinations thereof, and thereby making a tissue paper product that has a combination of highly useful properties.
A tissue product made from the process of the invention has highly useful properties. The degrading agent is located throughout the fibrous web formed by the process and the degrading agent is present throughout the tissue product in an amount that is sufficient to make the fibrous web exhibit (i) an immediate wet tensile strength of at least 90% of the wet strength as compared to a web that does not contain a degrading agent and (ii) a wet soak decay that is at least a ten point improvement as compared to a tissue fibrous web that does not contain a degrading agent. The improved decay provided by the system means that the risk of clogging of pipes and septic systems is reduced. While many consumers desire wet strength in their tissue, there are consumers who do not use tissue with a temporary wet strength agent due to this problem. The tissue made in accordance to the invention exhibits both high initial decay and a high initial wet strength would provide numerous benefits to both consumers and papermakers.
In one embodiment, the invention provides a tissue having an absorbent fibrous cellulosic web, wherein the tissue includes a combination of the following properties:

In one embodiment, the absorbency is less than 20 seconds or less than 15 seconds. In another embodiment, the absorbency is less than 10 seconds. In another embodiment, the absorbency is less than 5 seconds. In another embodiment, the absorbency is less than 2 seconds. In another embodiment, the absorbency ranges from 1 to 2, 5, 10, 15, 20, or 25 seconds. With respect to the improved decay, in one embodiment, the improved decay is at least 15 points. In another embodiment, the improved decay is at least 18 points or at least 20 points. In another embodiment, the improved decay ranges from 10 to 20 points.
The invention is further described in the following illustrative examples in which all parts and percentages are by weight unless otherwise indicated.

Example 1

A dose of 0.5% (based on dry fiber) EXPN 5032 glyoxalated polyacrylamide resin was added to a 0.6% pulp slurry in water and mixed well. The pulp slurry was then dewatered on a forming wire and dried into a 70 g/m²paper sheet.

Example 2

A blend of distearyl dimethyl ammonium chloride and cationic and anionic ethoxylated surfactants were dissolved in isopropyl alcohol. Magnesium peroxide powder was dispersed in this solution. While stirring, the isopropyl alcohol was evaporated, leaving a brittle white solid. The triturate was a fine white powder of coated magnesium peroxide. A dose of 0.5% (based on dry fiber) EXPN 5032 glyoxalated polyacrylamide resin was added to a 0.6% pulp slurry in water and mixed well. A dose of 0.25% (based on dry fiber) of the coated magnesium peroxide was then added to the pulp slurry and mixed well. The pulp slurry was then dewatered on a forming wire and dried into a 70 g/m²paper sheet.

Example 3

Calcium hydroxide powder was emulsified in a lotion base in a ratio of 2:3 calcium hydroxide to lotion. The result was a stable liquid. A dose of 0.5% (based on dry fiber) EXPN 5032 glyoxalated polyacrylamide resin was added to a 0.6% pulp slurry in water and mixed well. A dose of 0.25% (based on dry fiber) of the emulsion was then added to the pulp slurry and mixed well. The pulp slurry was then dewatered on a forming wire and dried into a 70 g/m²paper sheet.

Results

The sheets above were then cut into 2.5 cm by 10.2 cm strips. The strips were placed in a tensile tester, wet with water, then immediately pulled to measure tensile. New strips from the same sheet were placed in water for thirty minutes. These strips were then placed in the tensile tester and pulled to measure tensile. The percent decay was calculated using these measurements.
