DETAILED DESCRIPTION OF THE INVENTION The present inventors have conducted intensive studies,
It has been found that by providing a composition containing Compound A and Compound B, the dispersibility of the object is remarkably improved, and foaming is significantly reduced. In the present invention,
It is necessary to use the compound A and the compound B in combination, and when these are not used together, the improvement in dispersibility in water, the suppression of foaming, and the like become insufficient, and the desired effects cannot be obtained. Further, when the compound A and the compound B are used in combination, the compatibility between the compound A and the compound B is increased, and the stability as a treating agent is improved. In addition, it is possible to adhere the fibers uniformly and in the form of a film, and a more excellent effect can be obtained. Foamability and dispersibility are not significantly improved when only compound B is applied to the fiber, but when compound A and compound B are used together, both foamability and dispersibility are significantly improved.

The compounding ratio of compound A and compound B is
20 / 80-95 from the viewpoints of improvement in dispersion in water, suppression of foaming, etc.
/ 5, especially 90 / 15-30 / 70, further 85/15
It is preferably set to 〜50 / 50. Usually, when fibers or the like to which the treatment agent is attached are dispersed in water, bubbling tends to occur, and not only does the fibers and the like float and the process efficiency deteriorates,
At the time of papermaking, the fibers cannot be present in the foamed portion, so that the fiber density becomes extremely low. Therefore, the formation is extremely deteriorated and the paper strength becomes insufficient. Such a problem can be solved by using them together. At this time, when the compounding ratio of the compound A is increased, the uniform dispersibility of the fiber is increased, and when the compounding ratio of the compound B is increased, foaming in the papermaking process tends to be suppressed. The amount of the dispersant attached to the target is 0.0
It is preferable to be 5% by weight or more / object weight, especially 0.1% by weight or more / object weight, and even if the adhesion amount exceeds 3% by weight, various performances are not so improved and cost is not preferable. For this reason, the content is preferably 3% by weight or less, particularly preferably 1.5% by weight or less.

In the general formula (1), R1 represents an alkyl group having 1 or more carbon atoms. From the viewpoint of productivity, cost, degree of hydrophilicity, etc., R1 has 8 to 30 carbon atoms, especially 1
About 0-18 alkyl groups are preferred. The alkyl group may be linear or have a branched structure, but is preferably linear in view of cost, productivity, and the like. Further, m and n in the formula (1) represent natural numbers of 1 or more, and from the viewpoint of hydrophilicity, productivity, cost, etc., 2 ≦ n.
m + n ≦ 30, particularly preferably 6 ≦ m + n ≦ 20.

[0010] Further, R2 in the general formula (2) represents an alkyl group having 1 or more carbon atoms.
From the viewpoint of the degree of hydrophilicity and the like, an alkyl group having 8 to 30 carbon atoms, particularly about 10 to 20 carbon atoms, is preferred. The alkyl group may be linear or have a branched structure, but is preferably linear in terms of productivity, cost and the like. In the formula (2), s and t represent integers of 0 or more, and from the viewpoint of hydrophilicity, productivity, cost, etc., 1 ≦ s
+ T ≦ 20, particularly preferably 2 ≦ s + t ≦ 15. In the present invention, two or more compounds A or B may be used in combination.

The treatment agent of the present invention may be applied as it is to the object, such as a melt or the like, or may be an agent dissolved or dispersed in water or a non-aqueous solvent. When applied to an object (fiber or the like) having a low dissolution temperature, it is preferable to use a substance dissolved or dispersed in a non-aqueous solvent from the viewpoint of suppressing the occurrence of sticking. The amount of the solvent used is 10 to 200 with respect to the total weight of the compound (A) and the compound (B).
% By weight, and the viscosity of the treatment liquid is preferably 300 centipoise or less, more preferably 100 centipoise or less.

As the solvent, for example, lower monoalcohols such as methanol and ethanol, ethylene glycol, propylene glycol, hexamethylenediol,
Examples include polyhydric alcohols such as glycerin, polyoxyethylene-based compounds such as polyoxyethylene lauryl ether and polyoxyethylene octyl ether, and ether compounds thereof, ethylene glycol monoethyl ether, and ethylene glycol monobutyl ether. Particularly, the above-mentioned polyhydric alcohols are preferable. Water may be added to these.

The method of applying the treating agent of the present invention to an object is not particularly limited, and may be applied by, for example, a conventionally known method. For example, a method in which a dispersant is attached to a rotating roller, and a running yarn or the like is brought into contact with the roller to apply the dispersing agent.
A method of applying the yarn by running it in a chamber in which a dispersant is jetted is used. From the viewpoint of processability, a method of contacting with a rotating roller is preferably employed.

The treatment agent need not be applied to the entire object, but is preferably applied to 70% by weight or more, particularly 80% by weight or more, and more preferably 90% by weight or more of the surface area of the object. In order to apply uniformly to the whole object, it is preferable to measure uniformity of application by drying, heat treatment, or aging step after application, and to omit the step after application, so that the object before dry heat drawing is omitted. It is desirable to apply in a process.

The object to which the treatment agent of the present invention is applied is not particularly limited, and may be applied to fabrics such as woven fabrics and knits, pulp and the like. In particular, the dispersibility in water is improved, and foaming is suppressed. Therefore, a remarkable effect can be obtained when applied to papermaking paper stock, and a more remarkable effect can be obtained because fibers tend to have insufficient dispersibility and the like. Examples of applicable fibers include acrylic fibers, polyamide fibers, glass fibers, and polyvinyl alcohol fibers. Among them, it is preferable to use hydrophilic fibers from the viewpoints of adhesion between the fibers and the treating agent, dispersibility improving properties, and the like. Particularly, when a fiber containing a vinyl alcohol-based polymer is used, an excellent effect is obtained. . P that can be used in the present invention
VA is 70 mol% of vinyl alcohol units.
It is preferable to use a polymer containing the above, ethylene vinyl acetate, itaconic acid, vinylamine, acrylamide,
Vinyl pivalate, maleic anhydride, a sulfonic acid-containing vinyl compound, and the like may be copolymerized.

The degree of saponification is preferably at least 80 mol% from the viewpoints of water resistance, mechanical performance and the like, and at least 95 mol%, particularly from the viewpoint of enhancing the mechanical performance of the fiber by performing oriented crystallization. It is preferably at least 98 mol%, more preferably at least 99 mol%. Although the degree of polymerization of PVA is not particularly limited,
From the viewpoints of mechanical performance, water resistance and the like, the degree of polymerization is preferably 500 or more, more preferably 1500 or more.

The length of the fiber is not particularly limited, but in the case of wet papermaking using the fiber, the length is 1 to 20 mm from the viewpoint of uniform dispersibility, formation, paper strength (fiber entanglement) and the like. It is particularly preferable that the thickness be 3 to 10 mm. The thickness of the fiber may be set according to the purpose and application, and for example, a fiber of 0.1 to 3d can be suitably used.

In the present invention, a nonwoven fabric excellent in various properties such as feeling can be obtained by using easily splittable fibers further provided with a treating agent. That is, conventionally, the use of ultrafine fibers to obtain a nonwoven fabric having an excellent surface texture and feel has been studied.However, ultrafine fibers have a problem of high productivity and low productivity due to difficulties in manufacturing technology. 1
The spinning and spinning techniques for ultra-fine fibers of about / 1000 to 1 / 10000d have not been industrially established. For this reason, after manufacturing a sheet using easily splittable conjugate fibers,
It has been practiced to split easily splittable conjugate fibers into ultrafine fibers. For example, cut split conjugate fibers to about 5 mm, sheet them using a paper machine, and then pressurize the fibers by high-pressure water flow. There is known a method of making paper using ultra-fine fibers by dividing. At this time, if the fibers are not uniformly dispersed in the water, even if the dividing process is performed, only the portion where the fibers are in a lump is not sufficiently divided and thinned. In the present invention, since the fibers are extremely excellent in uniform dispersibility, a nonwoven fabric excellent in formation and feeling can be obtained.

The easily splittable fiber is not particularly limited, but it is preferable to use a fiber containing a vinyl alcohol-based polymer from the viewpoints of strength, uniform dispersibility, easy splitting and thinning, and particularly, PVA (Polymer X). ) Is preferably a sea-island fiber having a polymer (polymer Y) as an island component, which has low compatibility with the sea component and PVA but is soluble in a common solvent.
Among them, the polymer X is an acrylonitrile-based polymer (P
The fibers which are AN) are excellent in mechanical performance, lint-free property, and excellent in division thinning property, so that they can be suitably used. Since PVA and PAN have low compatibility and greatly different swelling properties with respect to water, they can be easily separated at the interface between both polymers by applying a high-pressure water flow or the like.

As the easily splittable fiber comprising PVA and PAN, those described in Japanese Patent Application No. 7-269519 can be suitably used. The weight ratio of PVA to PAN is 80:20 to 42:58, especially 65/35 to 45/5.
It is preferably set to 5. By adopting such a mixing ratio, it is possible to obtain a fiber which is excellent in mechanical performance and division thinning property and hardly causes sticking. At this time, even when a fiber made of PVA and another polymer is used, PVA as described above can be used. An acrylonitrile unit having 7 PANs is preferably used.
It is preferable to use 0 mol% or more of a polymer, such as (meth) acrylates such as methyl acrylate and ethyl acrylate, vinyl esters such as vinyl acetate and vinyl butyrate, vinyl compounds such as vinyl chloride, acrylic acid, Unsaturated carboxylic acids such as methacrylic acid and maleic anhydride, and sulfonic acid-containing vinyl compounds may be copolymerized. In order to improve the solubility in the undiluted solvent, a vinyl monomer other than the homopolymer is added in 0.1%.
Those copolymerized with 5 to 10 mol%, particularly 2 to 8 mol%, are preferred.

The desired fiber is obtained by dissolving such PVA and PAN in a common organic solvent, spinning the solution in a solidification bath by wet or dry-wet spinning, and drawing by dry heat. Common organic solvents include dimethylsulfoxide, dimethylacetamide, dimethylformamide, glycerin,
Ethylene glycol and the like. PVA concentration 6-6
It is preferable to use a spinning solution of 0% by weight. When this spinning solution is discharged into a coagulation bath, fibers are formed. The temperature of the solution at the time of discharging is preferably 40 to 170 ° C., and the spinning method may be a wet spinning method or a dry-wet spinning method. Examples of the coagulation bath include methanol, ethanol, acetone, methyl ethyl ketone, methyl isobutyl ketone, methyl acetate, benzene, toluene and the like. These coagulation baths
The solvent of the stock solution may be added, and the temperature of the coagulation bath is preferably −20 to 20 ° C.

It is preferable that the obtained fiber is wet-drawn by a factor of 2 to 8 in view of strength, easy splitting and the like. PVA after wet stretching
The fibers are immersed in a hardening bath to remove as much of the stock solvent contained in the fibers as possible and the fibers are dried. If necessary, dry heat stretching or heat treatment may be performed. By the above method, easily separable fibers suitable for the present invention can be obtained.

By using the paper material to which the treating agent of the present invention is added, the dispersibility of the paper material is improved, and foaming is suppressed, so that paper having excellent properties such as formation, paper strength and the like can be obtained. Is obtained. Needless to say, it is not necessary for all of the paper stock to be provided with a treatment agent, and papermaking may be performed using fibers to which the treatment agent has been added and pulp or binder to which no treatment agent has been applied. It is preferable that the amount of the paper material to which the treatment agent is added is 5% by weight or more, particularly 10% by weight or more, and further 60% by weight or more of the whole paper material. The blending of the stock may be appropriately set, but if a paper excellent in hand, water absorption and the like is desired, it is preferable to use easily splittable fiber, and 10% by weight or more, particularly 50% by weight or more, Further, the mixing ratio is preferably 90% by weight or more. It is preferable to make the composition taking into account the cost of paper, water absorption performance, paper strength and the like. Needless to say, fibers other than easily splittable fibers may be used in combination.

The binder fiber is preferably blended in an amount of about 10 to 20% by weight of the paper material. When a fiber containing a vinyl alcohol-based polymer is used as the fiber, the binder fiber has high adhesiveness to the fiber, and It is preferable to blend a polyvinyl alcohol-based fibrous binder having high water absorption. However, in the case of fibrillation by a high-pressure water stream after sheeting using easily splittable fibers, the fibers are sufficiently entangled by the high-pressure water stream and the form is stabilized, so that it is not necessary to use a binder fiber. Rather, the blending ratio of the binder fiber is preferably reduced since the feeling is increased and the liquid absorption is not hindered by the binder, and specifically, it is preferably 3% by weight or less, particularly 0.1% by weight or less. More preferred.

The papermaking method, the blending of the stock, etc. may be appropriately selected according to the purpose, and the papermaking may be carried out based on a conventionally known method. These paper stocks are dispersed to make paper,
The concentration of the stock is preferably about 1 to 10% by weight in the slurry and about 0.5 to 5% by weight in the chest. As the dispersion, it is preferable to use water at normal temperature (about 0 to 40 ° C.), but it may contain other liquids or may contain additives. According to the present invention, excellent effects can be obtained without adding other additives, but more excellent effects can be obtained by appropriately adding additives according to the purpose and the like. Specific examples of additives include sizing agents, paper-strengthening agents, fillers and other materials that improve paper performance,
Those which stabilize the papermaking process, such as a retention aid, a dispersant (a viscosity agent), an antifoaming agent, and a release agent, can be mentioned. Such a stock is made into a wet base paper, and the net used at this time may be a circular net or a short net. The method of drying the obtained wet paper is not particularly limited,
For example, a dryer such as a yankee type, a multi-cylinder type, a through-dryer type may be used. The drying method, etc., if the conditions of the drying method, drying time, drying temperature, etc. are determined by the composition of the paper, the thickness, the degree of refining of the stock, the moisture content before and after drying, the weight of moisture to be dried per unit time, etc. The drying is preferably performed at, for example, about 80 to 130 ° C.

For example, a desired paper can be obtained by the above-mentioned method. However, when easily splittable fibers are used, paper having a good feeling can be obtained by applying pressure to the paper to split the easily splittable fibers. can get. In particular, in the present invention, the stock is uniformly dispersed, and since foaming during papermaking is small, the texture is more excellent, and the space between fibers increases because the paper is constituted by ultrafine fibers, In addition, the effect of improving water absorption due to the occurrence of capillary action is obtained. Prior to papermaking, pulp or fiber refined by beating with a beater (Niagara-type, Labus-type, etc.), refiner (Shoryudin, conical, disk, etc.), homomixer, etc. may be used. Since there is a problem that the water-dispersibility of the material tends to be insufficient, it is preferable to split the fibers after producing the sheet-like material. At this time, a method may be adopted in which a part is divided and thinned before paper making, and then a sheet is further divided and further subjected to a division and thinning process. The method of dividing and thinning is not particularly limited, but it is preferable to divide by high-pressure flow, and a method of applying a high-pressure water flow of 60 kg / cm ² or more, preferably 80 kg / cm ² or more to papermaking by a high-pressure water entanglement device after wet papermaking. It is preferred to employ In addition, it is preferable to use an easily splittable fiber that can be divided and thinned when such a condition is adopted, from the viewpoint of processability and the like.

The paper obtained according to the present invention is excellent in uniform dispersibility of the stock, and is excellent in various properties such as formation and paper strength, so that it can be used for all purposes. The applicable application is not particularly limited, and can be applied to all fields such as sanitary materials, household goods, agriculture, fisheries, industrial use, electric appliances, and the like. For example, it can be used for tray mats, towels, decorative paper, and the like. In particular, when easily splittable fibers are used, the feeling, liquid absorption, and various properties such as paper strength are further improved, so that a particularly excellent effect is obtained as a tray mat, towel, decorative paper, and the like. In particular, since it has high paper strength and excellent liquid absorbency, it can be suitably used as a tray mat to be laid on a tray for packaging foods (fish meat and the like).
