Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a textile product and a method for dipping and water repelling the same. More specifically,
TECHNICAL FIELD The present invention relates to a flexible and durable water-repellent fiber product and a water-repellent finishing method capable of easily and economically treating the fiber product by a dipping method. Further, in addition to the above, the present invention relates to a textile product having both moisture absorption / release property and water repellency and a processing method thereof.

[0002]

2. Description of the Related Art Conventionally, as a method of imparting water repellency to fibers, a method of spraying or padding a fluorine-based water repellent having a polyfluoroalkyl group or a silicone water repellent has been adopted. Also, instead of these methods, JP-A-58-149385 and JP-A-60-2
276, JP 60-2780, and JP 6
There is also proposed a method in which the treatment is carried out in a dipped state, as in JP-A-0-88178.

[0003]

However, in the method of spraying or padding, the fiber product to be treated is limited to the sheet-shaped fiber product or the fiber product having no nap, and the non-sheet-shaped tube is used. If you try to apply it to textile products in the form of pieces or pieces in the form of panties, tights, socks, etc. or textile products with naps,
It is impossible to uniformly attach the treatment agent to the fiber surface, and it is practically impossible to obtain a water-repellent processed fiber product which is uniform and has excellent durability as a whole.

On the other hand, in the conventional dipping method, the utilization efficiency of the treating agent in the dipping bath is remarkably low, and it is necessary to use a large amount of salt together in order to attach all of the treating agent to the fibers, which is industrially necessary. It had very poor workability. Also,
The texture of the obtained fiber product was rough and hard, and lacked in flexibility.

Further, especially for pantyhose, there is not provided a material having a water-repellent property even in the rainy season and having a comfortable cooling function without feeling stuffy.

The present invention solves the problems of the prior art, and even in the case of a non-sheet-shaped tubular or piece-shaped fiber product such as pantyhose, tights, socks, or a fiber product having naps. It is an object of the present invention to provide an immersion water-repellent finishing method capable of performing uniform water-repellent finishing with excellent durability. Another object is to provide a material for pantyhose having water repellency and a comfortable cooling function without feeling stuffy.

[0007]

In order to solve the above-mentioned problems, the dipping / water-repellent finishing method for textile products of the present invention has the following constitution. That is, amino equivalent of 500 to 12000
A gram equivalent / mol of an aminosilicone resin and a fluorine-based water repellent are mixed in a ratio of 3.1: 6.9 to 8.3: 1.7 and immersed at 40 to 140 ° C in the presence of a strong base salt of a strong acid. The method is a method for dipping water-repellent finishing of a textile product, which is characterized in that it is treated by a method.

The textile product of the present invention has the following constitution. That is, it is composed of polyamide fiber containing 4.65 × 10 ⁻⁴ equivalent / g fiber or more of a carboxyl group substituted with an alkali metal, and has an amino equivalent of 500 to 12000 g / mol of aminosilicone resin and fluorine-based water repellent. It is a textile product characterized by being provided with.

In the treatment method of the present invention, an amino silicone resin having an amino equivalent weight of 500 to 12000 gram equivalent / mol is used. If a silicone resin is not used, the film-forming property is inferior, so that it is difficult to obtain a water-repellent finish having excellent durability. On the other hand, when the amino equivalent is less than 500 gram equivalents / mole, the hydrophobicity of the silicone resin is too strong and a uniform coating cannot be obtained, resulting in poor washing durability. On the other hand, when the amino equivalent is more than 12000 gram equivalent / mole, the hydrophilicity is too strong and the utilization efficiency of the silicone resin is lowered, so that the film formation becomes difficult.

Next, in the treatment method of the present invention, a fluorine-based water repellent is used. When an aminosilicone resin having the above-mentioned specific amino equivalent is treated alone without using a fluorine-based water repellent, there are problems that sufficient water repellency cannot be imparted, slipperiness when worn, and the like.
From the viewpoint of easily satisfying the soft texture and the durable water repellency which are the objects of the present invention, as a fluorine-based water repellent, a polymerizable resin containing a polyfluoroalkyl group having 3 to 21 carbon atoms. Compound or / and C3-21
It is preferable to use a reaction product of a polymerizable compound having one polyfluoroalkyl group and a urethane compound.

The polymerizable compound containing a polyfluoroalkyl group having 3 to 21 carbon atoms is an oligomer obtained from an unsaturated ester monomer such as an acrylate or methacrylate containing fluorine in the alcohol residue of the ester, or these compounds. Examples thereof include copolymerized oligomers with other polymerizable monomers copolymerizable with the monomers. Particularly preferred are oligomers of unsaturated esters having a perfluoroalkyl group at the terminal. The ester alcohol residue may be one having various substituents such as a hydroxyl group and a methoxy group, and these substituents may contain atoms such as sulfur, nitrogen and halogen. Absent.

Other polymerizable monomers that can be copolymerized with the above-mentioned polymerizable compound having a polyfluoroalkyl group having 3 to 21 carbon atoms include N-methylol acrylamide, N-methylol methacrylamide, and glycidyl acrylate. , Glycidyl methacrylate, aziridinyl acrylate, aziridinyl methacrylate, diacetone acrylamide, diacetone methacrylamide, methylol diacetone acrylamide, ethylene diacrylate, ethylene dimethacrylate, hydroxyalkyl acrylate, hydroxyalkyl methacrylate, 3-
In addition to monomers such as fluoro-2-hydroxypropylmethacrylate, vinyl chloride, ethylene, vinyl acetate, vinyl fluoride, acrylamide, methacrylamide, styrene, α-methylstyrene, p-methylstyrene, acrylic acid or methacrylic acid Examples thereof include alkyl ester, benzyl acrylate or methacrylate, vinyl alkyl ether, halogenated alkyl vinyl ether, vinyl alkyl ketone, cyclohexyl acrylate or methacrylate, maleic anhydride, butadiene, isoprene and chloroprene. A copolymer oligomer can be formed from one or more of these polymerizable monomers and an unsaturated ester monomer such as acrylate or methacrylate containing fluorine in the alcohol residue of the ester.

The copolymerization ratio of the unsaturated ester monomer having fluorine in such a copolymer oligomer is usually 1
0 to 90% by weight, especially 30 to 80% by weight are suitable.

Further, as the urethane compound capable of reacting with the polymerizable compound having a polyfluoroalkyl group having 3 to 21 carbon atoms, the following compounds are listed. However, in the formula, Rf is a polyfluoroalkyl group having 3 to 21 carbon atoms.
Was displayed. ◎ Here, the reaction mainly means a crosslinking reaction, but it does not exclude other reactions. In short, the number of carbon atoms is 3 to 21.
It may be any reaction as long as some chemical bond is generated between the polymerizable compound containing one polyfluoroalkyl group and the urethane compound.

[Chemical 10] In the present invention, the silicone-based resin and the fluorine-based water repellent are used in a ratio of 3.1: 6.9 to 8.3: 1.7, preferably 7: 3.
It is used by mixing in a ratio of 5: 5. When the ratio of the silicone-based resin to the fluorine-based water repellent was less than 3.1: 6.9, the water repellent in the treatment liquid was not exhausted unless a large amount of salt was allowed to coexist. Textile products have problems such as coarse and hard. On the other hand, when the ratio of the silicone-based resin to the fluorine-based water repellent exceeds 8.3: 1.7, the resin in the treatment liquid is easily exhausted to give a soft texture, but the obtained fiber product. Is excessively slippery, and defects in physical properties are likely to occur.

In the method of the present invention, a strong base salt of a strong acid is allowed to coexist. If a strong base salt of a weak acid or a weak base salt of a strong acid is allowed to coexist instead of a strong base salt of a strong acid, it is difficult to efficiently exhaust the silicone resin and the fluorine-based water repellent in the immersion bath into the fiber product. is there.

The strong base salt of a strong acid can be widely used as long as it does not impair the stability of the polyfluoroalkyl group-containing compound. A normal salt, an acid salt or a basic salt may be used as long as it is at least water-soluble. For example, as an inorganic salt,
Sodium chloride, lithium chloride, potassium chloride, sodium sulfate, potassium sulfate and the like are preferable.

The concentration of the strong base salt of the strong acid in the immersion bath is 0.01 to 10% by weight, more preferably 0.02 to 5% from the viewpoint of improving the utilization efficiency of the treating agent and facilitating workability. 0
It is preferably set to wt%.

As the fiber material of the fiber product to be treated in the method of the present invention, natural fibers such as cotton, silk, hemp and wool, synthetic fibers such as polyamide, polyester, acrylic and polypropylene, and semi-fiber such as rayon and acetate are used. Examples include synthetic fibers. The shape of the fiber product may be any of cotton, filament, sliver, yarn, cloth, non-woven fabric, rug, sewn product and the like.
Among these, among others, fiber products having a non-sheet shape, specifically, those having a tubular or piece shape such as sewn products, pantyhose, tights, and socks, and fiber products having naps In addition, the padding method can exert a particularly remarkable effect when the method of the present invention is applied to a material in which hair collapse occurs or in which uniform deposition of the treatment agent is extremely difficult.

In order to impart the water repellency and the cooling function to the pantyhose at the same time, 4.65 × 1 of the carboxyl group substituted with the alkali metal is used as the fiber material.
A polyamide fiber containing ^0-4 equivalents / g fiber or more is used. If the amount of the carboxyl group substituted with an alkali metal is less than 4.65 × 10 ⁻⁴ equivalent / g fiber, the stuffiness in the imperial family cannot be eliminated and the cooling function cannot be imparted. Here, the polyamide is
A polyamide such as nylon 6, nylon 66, nylon 4 or a copolyamide mainly composed of these.

As a method for introducing a carboxyl group substituted with an alkali metal into a fiber, a vinyl monomer having a carboxyl group such as acrylic acid, methacrylic acid, itaconic acid, maleic acid or the like is treated with ammonium persulfate, potassium persulfate or peroxide. There is a method of using a polymerization initiator such as benzoyl or a method of graft-polymerizing on the fiber polymer molecule by electron beam irradiation, or a method of mixing the vinyl monomer or its derivative in the fiber production stage. For this, the above-mentioned method by graft polymerization is advantageous.

When the carboxyl terminal group introduced by such means is subjected to alkali metal substitution treatment in an alkaline aqueous solution of a predetermined concentration such as sodium carbonate, potassium carbonate, sodium hydroxide or potassium hydroxide in consideration of equivalent weight, alkali metal substitution treatment is carried out. The carboxyl group substituted with 4.65 × 10 ^-4
Polyamide fiber containing more than equivalent / g fiber can be used.

In this case, the water repellent treatment described above is preferably performed after the alkali metal substitution treatment.

In the method of the present invention, the treatment temperature is 40 to
It is processed at any temperature of 130 ° C., 40
If the temperature is less than ℃, the treatment agent is hard to adhere to the fiber, while 130
If the temperature exceeds ℃, there is a problem that the silicone-based resin causes dispersion destruction.

That is, the fiber product is usually immersed in the treatment liquid having the above composition at room temperature, gradually heated to an arbitrary target temperature of 40 to 130 ° C., and treated at the target temperature for 10 to 30 minutes. Almost all amount of the active ingredient in the treatment liquid can be adhered to the fiber without waste.

The object of the present invention is to provide the silicone resin and the fluorine-based water repellent in the textile product after the treatment in an amount of 0.2 to 5.0% by weight in terms of the solid concentration of the adhered substance. It is preferred for obtaining a textile product having a water repellent which is durable by name.

The moisture absorption rate was measured as follows.
That is, about 1 g of a sample was placed in a glass weighing bottle, dried in a dryer set at 110 ° C. for 2 hours in an open state, and then allowed to cool in a desiccator filled with silica gel in a sealed state for 30 minutes, Precisely weigh this and let this be the dry weight W _d .

Next, the sample-containing weighing bottle was left for 24 hours in the thermo-hygrostat under the conditions of 20 ° C. and 65% RH with the temperature and humidity kept open, and then the weighing bottle was capped again. After leaving it in the desiccator filled with silica gel for 30 minutes in the closed state, weigh it precisely and leave it for the weight W _e
And

Moisture absorption rate = {(W _d / W _e ) −1} × 100 The moisture absorption rate at 30 ° C. and 90% RH is 20 ° C. above.

Except for changing the H condition to 30 ° C. and 90% RH, the same procedure is performed.

The moisture absorption rate at 30 ° C. and 90% RH and 2
The difference in moisture absorption rate at 0 ° C. and 65% RH is ΔMR. ΔM
The larger the value of R, the more excellent the cooling function and the more comfortable the material.
