Description

The present invention relates to a tissue softener composition, a method of treating a tissue by using the softener composition, and a tissue product treated with the softener composition.

In modern life, people increasingly want the softness of tissue. Therefore, it becomes increasingly important to use the appropriate fabric softener to improve the softness of the tissue. The term "tissue" specifically refers to routinely used paper products such as wet wipes, handkerchief wipes, napkins, cosmetological wipes, boxed wipes, which are generally consistent in softness, fluffiness, or water absorption. There is a request.

Fabric softener products for tissues are usually made of quaternary ammonium salts, lubricants, silicones and the like. It is usually added to the surface of the tissue by brush coating, roller coating, addition in slurry, and the like.

For example, CN101509213A discloses a bisamide quaternary salt tissue softener, as well as methods and uses thereof.

In addition, the effects of various cationic softeners on tissues are compared in YANG, Qinwu et al., "Effect of Different Cationic Softening Agents on Household Paper", Journal of Cellulose Science and Technology, Vol. 23 No. 1, Mar. 2015. Has been done. These cationic softeners include imidazoline, polyacrylamide, quaternary ammonium salts, fatty acid esters, and silicones. The results of the comparison show that amino-containing silicone softeners have the best optimized properties for softness.

However, in addition to improving the softness of the tissue, tissue manufacturers, especially wet wipe manufacturers, have found that the skin affinity of the tissue after treatment with the softener (especially skin irritation in the case of amino-containing silicone compounds) and the coating of the softener. There is increasing interest in how to increase weight, reduce manufacturing costs, save raw materials, and at the same time maintain the softness and tissue strength that is as immune to damage as possible.

Another document CN103061204B discloses, in particular, a diorganosilicone, an alcohol moisturizer containing a monovalent or polyhydric alcohol, and a softener emulsion composition containing a thickener. The recommended coat weight of the fabric softener emulsion composition is 1% to 20% based on the basis weight of the base tissue, and the composition must contain a thickener. Moreover, this document does not propose any particular diorganosilicone compound.

In addition, US5721297A discloses a novel piperidinyl organosiloxane. However, the organosiloxane is used in this document only as a light / UV stabilizer for polymer substrates such as polyethylene or polydiolefin.

In view of the above goals, the present application provides the softener composition of claim 1, comprising a combination of a particular aminosilicone with a monohydric or polyhydric alcohol in a particular amount ratio. Surprisingly, the inventors of this application have found that by using such a fabric softener composition, improved softness and increased coat weight can be achieved without compromising tissue strength. In particular, the coat weight of the softener composition can be increased to an amount of 20% or more with respect to the basis weight of the tissue without adding an additive for increasing the viscosity such as a thickener.

Moreover, the softener compositions according to the invention are more efficient than silicone-based or alcohol-based alone in improving softness under the synergistic action of aminosilicone with monovalent or polyhydric alcohols in specific proportions. be. In addition, the fabric softener composition according to the invention can maintain good water absorption of the treated tissue, reduce the tendency to yellow and provide good skin affinity.

In another aspect, the application also relates to a method for processing tissue.

Finally, the present application relates to tissue products obtained from the above methods.

Aminosilicone (also commonly known as aminosilicone oil) is known as a softener for tissue treatment. Such an amino-modified silicone compound is a polysiloxane having an amino group at its branch or terminal. Since the oxygen atoms of the silicone-oxygen bond in the backbone can adhere to the surface of the fiber, hydrophobic groups are oriented and placed along the surface of the tissue fiber, thereby forming a hydrophobic and flexible continuous thin film. Can soften the tissue. However, conventional aminopolydimethylsiloxane is irritating to the skin and eyes. Also, the tissue treated by them is prone to yellowing under high temperature and ambient conditions, which can shorten the shelf life of the treated tissue. Due to the water repellency of the silicone film, the water absorption properties of the treated tissue are significantly reduced.

However, the inventors of this application use the specific aminosilicones described below in combination with monohydric or polyhydric alcohols, especially polyhydric alcohol compounds such as glycerin, to further significantly improve softness and coat weight. It has been found that the mechanical properties are maintained or even increased without being impaired, while achieving significant improvements in. In addition, the treated tissue maintains the water absorbency of the base tissue, is not vulnerable to yellowing or color changes, and has good skin affinity.

As another component of the softener composition of the present invention, a monohydric or polyhydric alcohol compound is used. Within the scope of the invention, suitable monohydric or polyhydric alcohols are understood to be compounds having one or more hydroxyls per molecule on average, preferably fatty alcohols or polyether alcohols.

In an advantageous embodiment, a suitable monohydric or polyhydric alcohol compound may have the formula A- (OH) z.
z represents an integer of 1 to 6, preferably 1 to 4, and more preferably 2 to 3.
A represents 1 to 12 carbon atoms, preferably 2 to 8 carbon atoms, more preferably 3 to 8 carbon atoms, such as an aliphatic group having an alkyl, or a molecular weight of 40 to 1600. Represents a polyether segment.

Preferably, the polyether segment is an aliphatic polyether segment, more preferably selected from segments having 4 to 25 polyoxyethylene and / or polyoxypropylene groups.

Here, the position of the hydroxyl is not limited and can be the terminal or side of the group A.

Preferably, examples of monohydric or polyhydric alcohol compounds according to the invention include ethanol, propanol, butanol, pentanol, hexanol, heptanol, octanol, glycol, propanediol, glycerin, diethylene glycol, trimethylolpropane, hexanediol, or. Polyether polyols such as polyoxyethylene or polyoxypropylene diols or triols are included. Preferably, the monohydric or polyhydric alcohol compound is selected from glycol, trimethylolpropane, propanediol and / or glycerin. The inventor of the present application is that when glycerin (glycerol) is used as a monohydric or multivalent alcohol component in the composition, the treated tissue can have more optimum softness, slipperiness and moisturizing property. I found.

Therefore, in a particularly preferred embodiment, the monohydric or polyhydric alcohol component is at least 95% by weight, preferably at least 98% by weight, more preferably at least 99% by weight, particularly preferably 99.5% by weight, even 100%. Contains% by weight glycerin.

Furthermore, in order to achieve the above effects of the present invention, the weight ratio of the aminosilicone to the polyhydric alcohol component must be in the range of 0.001 to 0.2. If a weight ratio outside this range is adopted, the treated tissue may feel uncomfortable, the moisturizing property may be reduced, and the mechanical properties and the coat weight may be adversely affected. Advantageously, the weight ratio of the aminosilicone to the monovalent or polyhydric alcohol is 0.001 to 0.2, preferably 0.002 to 0.15, more preferably 0.005 to 0.10. It is preferably 0.01 to 0.08.

Examples of cationic emulsifiers are quaternary ammonium salt emulsifiers such as alkyltrimethylammonium chloride, dialkyldimethylammonium chloride and alkylbenzyldimethylammonium chloride.

The viscosity of the composition usually has a relatively significant effect on the amount of sizing (ie, coat weight). If the viscosity is too low, it is not advantageous for the applied composition to adhere to the surface of the coating roller. If the viscosity is too high, the fluidity will be poor and it will be difficult to obtain a uniform coating. Therefore, in the prior art, a certain amount of thickener is generally added to the softener composition in order to adjust the viscosity. However, the addition of thickeners impairs the feel of the tissue product while adversely affecting the resistance of the product to bacteria. Therefore, in the present invention, the preferred composition comprises less than 0.1% by weight, more preferably less than 0.05% by weight, and most preferably no thickener. Such thickeners are, for example, polyacrylic acid, cellulose, salts of alginic acid, and guar gum thickeners.

In a preferred embodiment, the composition is an emulsion.

In another preferred embodiment, the composition comprises 20% to 88% by weight, for example 30% to 70% by weight or 35% to 60% by weight of water, based on the total weight of the composition. ..

A second aspect of the present invention relates to a method for preparing the softener composition.

The softener composition of the present invention can be obtained by mixing the components in the indicated amounts in a simple manner and stirring thoroughly to form a stable emulsion.

In a further aspect, the application also relates to a method of softening the tissue. The treatment method is a post-treatment method such as spray coating, roller coating, and printing. For example, the fabric softener composition according to the invention is applied directly to the surface of the tissue product to be treated, for example, during the process of winding or rewinding the tissue, or other process of making the tissue, by the method described above. Can be done.

In an advantageous embodiment of the softening treatment of the tissue, the softener composition is coated on the surface of the tissue in an amount greater than 20%, preferably 25% to 35%, based on the basis weight of the tissue. Preferably, after application, aminosilicone is distributed in an amount of 0.01-3.2 g / m ² , preferably 0.04-2 g / m ² on each square meter of tissue surface, with hydroxyls of 0.5-.
