DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a synthetic fiber structure having antistatic properties and water repellency.

[0002]

2. Description of the Related Art Although synthetic fibers are hydrophobic, few of them have a strong hydrophobicity to exhibit a water-repellent function. Things can be mentioned. Therefore, usually, an organic compound having a perfluoroalkyl group as a main component is applied to a synthetic fiber structure, and water repellency is imparted by heat treatment. However, synthetic fiber structures, especially these water-repellent products, generally have a property of easily accumulating static electricity, and tend to cause various phenomena such as clinging of clothes, adsorption of dust, spark discharge, etc., which may cause obstacles in use. There are many. In addition, sometimes it is charged with a high voltage, giving the wearer discomfort.

[0003] In order to eliminate such drawbacks, conventionally, a fluorine-based water repellent is repelled with a cationic antistatic agent, an anionic antistatic agent, a nonionic antistatic agent, an organic amine salt, an inorganic salt, or the like. A method in combination with a water processing agent is usually performed. However, for example, in the case of a cationic antistatic agent, low-temperature treatment shows a good antistatic effect, but does not provide washing durability water repellency. On the other hand, there is a disadvantage that the antistatic function is lost in the high-temperature treatment. Anionic antistatic agents, organic amine salts and inorganic salts are not preferred because they also lower the initial performance of water repellency and the washing durability. In addition, since the nonionic antistatic agent has low antistatic ability, it must be used in a large amount in order to obtain sufficient antistatic properties, and the water-repellent washing durability is significantly reduced.

In order to solve these problems, a method has been proposed in which an antistatic agent is put into a synthetic fiber polymer, melt-spun to form a fiber structure, and water repellency is imparted by post-processing. The amount of the effective antistatic component existing on the fiber surface is insufficient, and the antistatic component may fall off or be buried by dyeing or finishing, and the antistatic effect is not sufficient.

As described above, it is extremely difficult to simultaneously impart antistatic property and water repellency with washing durability, and there has been no satisfactory treatment method.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a synthetic fiber structure having anti-static properties and water repellency having washing durability. To offer.

[0007]

An object of the present invention is to provide a synthetic fiber structure in which a polyetherester resin layer is formed on the surface thereof and contains a cationic antistatic agent or an anionic antistatic agent outside the layer. This is achieved by a synthetic fiber structure having antistatic properties and water repellency, wherein a fluorine-based water repellent film is formed.

The polyetherester resin is used in an amount of 0.1 to 6% by weight, preferably 0.1% by weight, based on the synthetic fiber structure.
It is applied in an amount of 3 to 4% by weight to form a resin layer on the surface of the synthetic fiber structure. The application of the polyetherester resin to the synthetic fiber structure is performed by an appropriate method such as a dipping method, a padding method, or a spraying method. Of course, it may be applied simultaneously with the dye at the time of dyeing.

The fluorine-based water repellent used in the present invention is known. Those having a perfluoroalkyl group as a main component are preferred. The water repellent is applied in an amount of 0.3 to 1.5% by weight, preferably 0.5 to 1% by weight, based on the synthetic fiber structure.

The cationic antistatic agent and the anionic antistatic agent used in the present invention are known. The cationic antistatic agent is preferably a quaternary ammonium salt-based antistatic agent, and the anionic antistatic agent is preferably a mixture of a pyrophosphate and an organic phosphate. Such a cationic antistatic agent or an anionic antistatic agent,
10 to 80% by weight, especially 20 to 80% by weight based on the fluorine-based water repellent
It is preferable to use 60% by weight.

In the present invention, it is preferable to use an aminoplast resin in order to improve the washing durability of the water repellency. Suitable aminoplast resins include, for example, dimethylol dihydroxyethylene urea, triazone formaldehyde, urea formaldehyde, ethylene urea formaldehyde, other N-methylol compounds,
-A methylol ether compound can be used with an amine salt or a metal salt as a curing catalyst. The ammonoplast resin is preferably used in an amount of 0.05 to 5% by weight based on the synthetic fiber structure, and an organic amine salt is preferably added as a catalyst in an amount of 50 to 100% by weight based on the aminoplast resin. By including the aminoplast resin, the washing durability of water repellency is remarkably improved.

A bath containing a cationic or anionic antistatic agent, a fluorine-based water repellent, and preferably an aminoplast resin is applied to the synthetic fiber structure, and a bath is formed on the outside of the polyetherester resin layer. Form a film. The application is carried out by an appropriate method, for example, a dipping method, a padding method, a spraying method or the like, and preferably drying is carried out at 80 to 80%.
The heat treatment is carried out at 130 ° C. for 20 seconds to 5 minutes, preferably at 120 to 200 ° C. for 20 seconds to 5 minutes.

[0026]

[Function] Since the fluorine-based water repellent film containing a cationic antistatic agent or an anionic antistatic agent is formed on the outermost layer, good water repellency can be obtained by the fluorine-based water repellent, The antistatic agent provides antistatic properties.

Further, since the polyetherester resin layer is formed on the inner side, the antistatic effect is further improved by the hygroscopic action of the polyetherester resin, and since the polyetherester resin is not exposed to the outside, it is repelled. The water is not alienated.

Hereinafter, the present invention will be described in more detail with reference to examples, but the present invention is not limited to these examples.
