Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a moisture-permeable waterproof cloth having excellent moisture-permeability and waterproof performance and having a function of absorbing and deodorizing a bad odor generated by a human body.

[0002]

2. Description of the Related Art Conventionally, it has been known that a coated cloth obtained by a wet or dry coating method has a resin layer with a hole and a resin layer without a hole. In general, when the resin layer is perforated, excellent moisture permeability is easily obtained, but the waterproof performance tends to be insufficient. Conversely, when the resin layer is non-porous, excellent waterproof performance is easily obtained, The wet performance tends to be insufficient.

In recent years, for the purpose of compensating for both defects, first, a highly moisture-permeable resin layer having pores is formed on a fiber cloth, and then a non-porous resin layer is formed on the resin layer, which is excellent. Attempts have been made to obtain a moisture-permeable performance and a waterproof performance, but in this method, a highly moisture-permeable resin layer having a hole is formed at a maximum of 5000 to 6000 even by the wet method.
Only moisture permeability of about g / m ² · 24hr is obtained, so even if the next non-porous resin layer is applied thinly, the moisture permeability is extremely reduced, resulting in excellent moisture permeability. Currently, it is difficult to achieve both waterproof performance. Moreover, in this case, coating is performed twice, which is also disadvantageous in terms of processing cost.

On the other hand, in Japanese Patent Laid-Open No. 58-4873 and Japanese Patent Publication No. 62-53632, the average particle diameter of which the main component is silicon dioxide is 2 to 50 .mu.m and the total pore volume is 0.2 to 5.
A processing method has been proposed in which a polyurethane resin film containing milliliters / g of porous particles is formed, and then a water repellent having a perfluoroalkyl group is added to obtain a moisture-permeable waterproof fabric. However, even with this method,
The moisture vapor transmission rate is 3000g / m ² · 24hr at most, and sufficient moisture vapor transmission performance is not obtained.

Further, Japanese Patent Application Laid-Open No. Hei 2-251672 discloses that a micropore having a diameter of less than 150.degree.
A method for processing a polyester-coated cloth having a resin layer in which inorganic porous particles of 0 m ² / g or more, such as silicon dioxide and titanium oxide, are layered and dispersed at a high concentration has been proposed. It only prevents migration of the dye, and does not have sufficient moisture permeability.

On the other hand, various deodorizing methods have been proposed and implemented as a method for removing the malodors associated with daily life. For example, physical adsorption method, chemical adsorption method (oxidation method,
Neutralization method, etc.), masking method, etc. are used as the general deodorizing method, and as a special method, cleaning method, combustion method, biological method, etc. are also used. Further, in recent years, fibers and cloths having a deodorant property by imparting metal phthalocyanine or the like to the fibers have been known mainly in cellulose fiber, but the deodorant property is also provided in addition to the moisture permeability and the waterproof property. The multi-functional material, which has also been proposed, has not been developed so far.

[0007]

[Problems to be Solved by the Invention] In addition, when an exercise involving sweating such as sports is carried out, a body odor is liable to be generated, and the odor is annoying not only to the person himself but also to the people around him. This was where a good solution to do was desired.

The present invention has been made in view of the above circumstances, and provides a deodorant moisture-permeable waterproof coating fabric having excellent moisture-permeability and waterproof performance, and also having an excellent deodorant function. The purpose is to obtain.

[0009]

SUMMARY OF THE INVENTION The present invention achieves the above object and has the following configuration. That is, the present invention has a perforated resin layer having a porosity of 40% or more made of a synthetic polymer mainly composed of a polyurethane resin on a fiber cloth, and the resin layer having an average particle diameter of 1.5 μm or less. 1 to 40% by weight of fine powder having deodorant property and average particle size of 1 μm
Inorganic fine powder having an adsorption amount of N, N-dimethylformamide of 200 ml / 100 g or more
A deodorant moisture-permeable waterproof coating fabric characterized by having a water content of 7,000 g / m ² · 24 hr or more and a water pressure resistance of 0.5 kgf / cm ² or more is contained. Hereinafter, the present invention will be described in detail.

The feature of the coated cloth in the present invention is that during production, 1 to 40 fine powder having a deodorant property with an average particle size of 1.5 μm or less is added to a cloth in a polar organic solvent solution of a synthetic polymer mainly composed of a polyurethane resin. Wt% and average particle size is 1
Inorganic fine powder having an adsorption amount of N, N-dimethylformamide of less than μm and 200 ml / 100 g or more is uniformly dispersed and applied by 1% by weight or more, and then immersed in water to form a resin film. A high-permeability and deodorant property with fine pores and a large number of pores is produced on the textile fabric used as the base fabric by the coating method without deteriorating the waterproof property originally possessed by the polyurethane resin-based synthetic polymer. A resin layer having both is formed.

Examples of the deodorant fine powder used in the present invention include inorganic deodorants such as silica gel, zeolite, activated carbon, activated clay, molecular sieves, aluminum dihydrogen tripolyphosphate, metal phthalocyanines, and phosphoric acid compounds of silicon. And iron (II) -ascorbic acid, microencapsulated products of organic deodorants that are extracts from conifers and hardwoods, etc. It may be an odorant.

These deodorant fine powders need to have an average particle size of 1.5 μm or less. If the average particle size exceeds 1.5 μm, the specific surface area (surface area per unit weight) of the deodorant fine powder becomes too small, the deodorizing effect is reduced, and the micropores in the resin layer are blocked, resulting in moisture permeability. If the particle size is decreased, or if the particles become large, streaks are generated on the surface of the resin film, which may deteriorate the quality or the waterproof performance of the part, which is not preferable.

The content of the deodorant fine powder is appropriately 1 to 40% by weight, preferably 5 to 35% by weight, based on the weight of the resin film. If the content is less than 1% by weight,
If the desired deodorant performance is not obtained, and if it exceeds 40% by weight, the physical properties of the film deteriorate, and the moisture permeability and waterproof performance also deteriorate.

In the present invention, the resin layer containing the deodorant fine powder formed on the surface of the fabric must have a porosity of 40% or more as expressed by the following formula [I]. Here, if the porosity is less than 40%, the contact area of the deodorant fine powder contained in the resin with respect to the bad odor becomes small, so that the deodorizing effect cannot be sufficiently expected. P = {1- (W / S · d) ÷ ρ} × 100 [I] (where P is the porosity (%), S is the area of the resin layer (cm ² ),
W is the weight of the resin layer in that area (g), d is the thickness of the resin layer (cm), and ρ is the resin density (g / cm ³ ). )

On the other hand, in the present invention, the resin layer also contains 1% by weight or more of an inorganic fine powder having an average particle size of 1 μm or less and an adsorption amount of N, N-dimethylformamide of 200 ml / 100 g or more. ing.

As the inorganic fine powder used here, inorganic fine powder pulverized by a usual wet pulverizing method, a ball mill pulverizing method or the like, a gas phase oxidation method of a metal halide, a combustion hydrolysis method, an electric arc method, etc. The metal oxide fine powder obtained by the dry method can be mentioned, and among them, the silicon dioxide fine powder produced by these methods can be mentioned as a representative. The fine powder obtained by these methods generally has a particle size of 0.05 μm or less and at the same time has a very large amount of N, N-dimethylformamide adsorbed, and can be added to a synthetic polymer resin solution. It is suitable as an inorganic fine powder. Further, if the surface of the fine powder is modified to be hydrophobic, it is more preferable from the viewpoint of water leakage, and the fine powder is preferably substantially non-porous.

As used herein, the amount of N, N-dimethylformamide adsorbed means that 5 g of inorganic fine powder is placed on a glass plate,
Every time one drop of N, N-dimethylformamide was dropped, the work of kneading was repeated using a spatula made of stainless steel, and N, N-dimethyl required until just before one drop of N, N-dimethylformamide suddenly became soft. It means the volume of formamide (unit: milliliter).
This is the one in which N, N-dimethylformamide was used instead of the oil of SK-5101 boiled linseed.

The inorganic fine powder used in the present invention is required to have an average particle size of 1 μm or less, and N, N-
Adsorption amount of dimethylformamide is 200ml / 1
It is necessary to be more than 00g, and the average particle size is less than 0.1μm and 250ml / 1
A substance having an adsorption amount of N, N-dimethylformamide of 00 g or more is more preferable in terms of the effect of the present invention. If the average particle size exceeds 1 μm, the fine pore size of the moisture permeable membrane of the resulting coated fabric becomes too large and the waterproof performance is deteriorated, which is not preferable, and the adsorption amount of N, N-dimethylformamide is 200 ml / 10.
If it is less than 0 g, the number of fine pores of the moisture permeable membrane becomes small, high moisture permeability cannot be obtained, and the porosity P becomes small, which is not preferable.

It is necessary that the inorganic fine powder used in the present invention is uniformly contained in an amount of 1% by weight or more, more preferably 3% by weight or more, based on the resin layer composed of a synthetic polymer mainly composed of polyurethane resin. It is good to be 1% by weight
When it is less than 1, the number of fine pores in the moisture permeable membrane of the obtained coated fabric is small, high moisture permeability cannot be obtained, and the porosity is also small. The inorganic fine powder does not necessarily have to be highly pure, and may contain other inorganic substances such as pigments and fillers as impurities.

The fiber cloth used as the base cloth in the present invention includes polyamide synthetic fibers represented by nylon 6 and nylon 66, polyester synthetic fibers represented by polyethylene terephthalate, polyacrylonitrile synthetic fibers, polyvinyl alcohol series. Examples thereof include synthetic fibers, semi-synthetic fibers such as triacetate, and woven fabrics, knitted fabrics, non-woven fabrics and the like made of mixed fibers such as nylon 6 / cotton and polyethylene terephthalate / cotton.

In the present invention, the above-mentioned fiber cloth treated with a water repellent may be used. This is one means for preventing the penetration of the resin solution into the fabric during manufacturing. In this case, the water repellent may be a known one such as a paraffin water repellent, a polysiloxane water repellent, or a fluorine water repellent, and the treatment thereof is also a commonly used padding method, spray method, or the like. The known method may be used. When particularly good water repellency is required, a fluorine-based water repellent is used. For example, Asahi Guard 730 (Asahi Glass Co., Ltd., fluorine-based water repellent emulsion) is padded (squeezed) with a 5% aqueous dispersion. The heat treatment at 160 ° C. for 1 minute, and the like.

In the coated cloth of the present invention, a solution of a synthetic polymer mainly composed of a polyurethane resin containing the above-mentioned two kinds of fine powders is applied onto the above-mentioned fiber cloth by a wet coating method. The polyurethane resin-based synthetic polymer as referred to herein means one containing a polyurethane component in an amount of 50 to 100% by weight, and other synthetic polymers include, for example, polyacrylic acid, polyvinyl chloride, polystyrene, polybutadiene, polyamino acid. Etc. and their copolymers and the like in an amount of less than 50% by weight. Of course, compounds modified with fluorine or silicon can also be used in the present invention.

The polyurethane resin is a copolymer obtained by reacting an isocyanate with a polyol, and aromatic diisocyanate, aliphatic diisocyanate and alicyclic diisocyanate are used alone or as a mixture thereof as an isocyanate component. 2,4
-Diisocyanate, 4,4'-diphenylmethane diisocyanate, 1,6-hexane diisocyanate, 1,4-
Cyclohexane diisocyanate or the like is used, polyether polyol or polyester polyol is used as the polyol component, polyethylene glycol, polypropylene glycol, polytetramethylene glycol or the like is used as the polyether polyol, and ethylene glycol or propylene glycol or the like is used as the polyester polyol. The reaction product of the diol with the dibasic acid such as adipic acid and sebacic acid, and the ring-opening polymer such as caprolactone are used.

The above-mentioned polyurethane polymer-based synthetic polymer solution containing two kinds of fine powder may be appropriately coated by a conventional coating method such as a knife coater, a comma coater or a reverse coater. In order to obtain a water pressure resistance of 0.5 kgf / cm ² or more, the smoothness and air permeability (JIS L-
1096 method), but generally, the coating amount is adjusted so that the weight of the resin film is 5 g / m ² or more, preferably 10 g / m ² or more.

In the present invention, for the purpose of improving the peeling resistance between the resin layer and the fiber cloth, a compound having a high affinity with the resin or the fiber cloth may be used in combination, and an isocyanate compound may be used in combination as the compound. .

As the isocyanate compound, 2,4-tolylene diisocyanate, diphenylmethane diisocyanate, isophorone diisocyanate, hexamethylene diisocyanate or a compound containing 3 mol of these diisocyanates and active hydrogen (eg, trimethylolpropane, glycerin, etc.) Triisocyanates obtained by addition reaction with 1 mol can be used. The above isocyanates may be in a form in which the isocyanate group is free, or may be in a form in which the block is dissociated by the subsequent heat treatment, which is stabilized by adding phenol, methylethylketoxime and the like, It may be properly used depending on workability and purpose.

The isocyanate compound is preferably used in an amount of 0.1 to 10% by weight based on the synthetic polymer mainly composed of polyurethane resin.
If the amount used is less than 0.1% by weight, the adhesive strength of the resin layer to the fabric is low, and if it exceeds 10% by weight, the texture tends to harden, which is not preferable.

In the present invention, after the resin liquid consisting of the polyurethane-based synthetic polymer as described above is applied to the fiber cloth, it is immersed in water at 0 to 30 ° C. for 0.5 to 10 minutes to wet-solidify the resin portion. To do. Below, in warm water of 40-60 ° C
After washing for 15 minutes, it is dried by a usual method.

In the present invention, for the purpose of further improving waterproofness, the coated fabric may be subjected to water repellent treatment after wet coating. For the water repellent treatment, a known water repellent treatment method which is generally performed as described above may be employed.

[0030]

[Function] The deodorant moisture-permeable waterproof coating fabric of the present invention is
Porosity 40 composed of polyurethane resin-based synthetic polymer
% Or more of fine resin particles having an average particle size of 1.5 μm or less in the resin layer having pores and an average particle size of 1 μm or less, and adsorbing amount of N, N-dimethylformamide of 200 ml / 100 g By containing the above-mentioned inorganic fine powder, excellent deodorant performance, excellent moisture permeation performance and waterproof performance are simultaneously given.

For this reason, fine powder having an average particle size of 1.5 μm or less and having an odor eliminating property and an inorganic powder having an average particle size of 1 μm or less and an adsorption amount of N, N-dimethylformamide of 200 ml / 100 g or more. The reason why it is possible to obtain excellent deodorant performance and excellent moisture permeation performance and waterproof performance at the same time by incorporating fine powder has not been clarified yet, but the present inventors have as follows. I'm guessing.

That is, a cloth is coated with a synthetic polymer solution mainly composed of a polyurethane resin in which an inorganic fine powder having an average particle size of 1 μm or less and an adsorption amount of N, N-dimethylformamide of 200 ml / 100 g or more is uniformly dispersed. When wet coagulation is carried out, water as a coagulating liquid and N, N-dimethylformamide as a resin solvent are mixed, and the resin is coagulated due to the rapid separation of the solvent from the resin liquid. The average particle size is 1 μm or less, and N,
When the inorganic fine powder having an adsorption amount of N-dimethylformamide of 200 ml / 100 g or more is uniformly dispersed in the resin solution, the surface of the inorganic fine powder is more likely to have N, N in the resin solution than other portions. -The concentration of dimethylformamide is high, in other words, the concentration of the synthetic polymer mainly composed of polyurethane resin is low. Therefore, in the wet coagulation process, water as the coagulating liquid is the N,
It replaces N-dimethylformamide and rapidly solidifies around the inorganic fine powder, after which the entire resin solidifies, resulting in a faster solidification rate, and in addition to the honeycomb structure peculiar to urethane resin, fine particles of 1 μm or less It is a very porous morphology with numerous holes.

Therefore, excellent waterproofness is exhibited by the fineness of the formed fine pores, and high moisture permeability is exhibited by the innumerable fine pores. In addition, when a substance having a deodorant property is contained in the microporous resin film having a porosity of 40% or more formed on the cloth, the substance having a deodorant property causes a bad odor such as body odor. It is presumed that it is possible to obtain a highly moisture-permeable waterproof cloth having excellent deodorant performance, since the area of contact with the cloth becomes wider.
