Description

Description ARAMID FIBER COATED WITH SYNTHETIC RESIN
Technical Field
[1] Generally, an aramid fiber is chiefly used to produce bulletproof vests, wear-resistant products, and the like because it has high tensile strength, wear resistance, durability, and the like.
[2] When an aramid fiber is formed into the above products, it is formed in one of three shapes depending on the intended use and then used. Examples of the three shapes include a filament shape, a pulp shape, and staple shape. In the filament shape, an aramid fiber is formed into a fabric by drawing it in a yarn shape, in the pulp shape, an aramid fiber is formed into a powdered product, and in the staple shape, an aramid fiber is slightly pulverized in order to freely adjust the thickness of yarn and to mix it with different yarns and then spin them into a fabric.
[3] When products are produced using the aramid fiber formed in one of the three shapes, the properties of the aramid fiber are reflected in the products, thus improving durability, wear resistance and tensile resistance of the products. Background Art
[4] In a process of producing the product, generally, a powdered aramid fiber is added.
However, the powdered aramid fiber is problematic in that it is easily conglomerated and thus is not uniformly dispersed in the products, so that a nonuniform phenomenon, in which the aramid fiber is excessively distributed in one part of a final product and is slightly distributed in the other part of the final product, occurs, thereby remarkably deteriorating the function of the final product.
[5] Conventionally, in order to solve the above problem, an apparatus for uniformly dispersing an aramid fiber has been used when the aramid fiber is added in the process of producing the product. However, the apparatus is problematic in that it is very expensive, and production cost is excessively high compared to output, thus decreasing production efficiency.
[6] Further, since an aramid fiber has excellent durability, wear resistance and tensile strength, it is difficult to cut the aramid fiber using general cutting means.

Technical Problem
[7] Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide an aramid fiber coated with a synthetic resin, by which a raw aramid fiber formed in a staple, filament or pulp shape is selectively coated with a phenol resin, a silicon resin or the like depending on the use of the aramid fiber, so that the aramid fiber can be easily pulverized and the pulverized aramid fiber is not conglomerated and thus is easily dispersed, with the result that the aramid fiber can be uniformly dispersed in a product without using an expensive dispersing apparatus in a process of producing the product, thereby drastically reducing the production cost of the product and further improving the production efficiency thereof. Technical Solution
[8] In order to accomplish the above object, preferred embodiments of the present invention will be described in detail with reference to the attached drawings.

[10] The present invention provides an aramid fiber 2 coated with a synthetic resin 1.
Since the aramid fiber 2 is coated with the synthetic resin 1, the aramid fiber 2 is easily pulverized into powdered aramid fiber, and the powdered aramid fiber is also rendered easily dispersible.
[11] Here, the thickness of the synthetic resin 1 applied on an aramid fiber 2 having a staple or filament shape is 1 ~ 20% of the diameter of the aramid fiber 2.
[12] Further, the amount of the synthetic resin 1 applied on an aramid fiber 2 having a pulp shape is 1 — 20% by weight of that of the aramid fiber 2.
[13] Furthermore, as the synthetic resin 1, either a phenol resin or a silicon resin is applied on the aramid fiber 2 depending on the use of the product produced using the aramid fiber 2 and the shape of the aramid fiber 2.
[14] As described above, since the aramid fiber 2 is coated thereon with the synthetic resin 1, the surface of the aramid fiber 2 is hardened, and this hardened aramid fiber can be easily pulverized and cut, and the pulverized aramid fiber is not conglomerated and thus is easily dispersed, so that the aramid fiber is uniformly dispersed over the entire product when it is added in a process of producing the product.
Advantageous Effects

Best Mode for Carrying Out the Invention
[23] Hereinafter, a process of coating an aramid fiber 2 with a synthetic resin 1 according to an embodiment of the present invention will be described.
[24] The process of coating an aramid fiber 2 with a synthetic resin 1 comprises: 1) preparing aramid fiber 2 formed in three shapes, such as a staple shape, a filament shape and a pulp shape; 2) immersing the aramid fiber 2 into an impregnation furnace filled with a coating solution in which a volatile solvent, such as alcohol, toluene or the like, is mixed with a phenol resin or a silicon resin depending on the shape and use of the aramid fiber 2 to coat the aramid fiber 2 with a synthetic resin 1; 3) primarily drying the aramid fiber 2 impregnated with the coating solution at a temperature of 6O0C for 1 hour using hot air; and 4) secondarily drying the aramid fiber 2 by passing the aramid fiber 2 through a heat treatment furnace, the temperature of which is sequentially increased from 8O0C to 22O0C over 4 hours.
[25] Here, the kind of a synthetic resin included in the coating solution charged in the impregnation furnace is changed depending on the shape and use of the aramid fiber 2. Therefore, the synthetic resin 1 applied on the aramid fiber 2 will be described depending on the shape of the aramid fiber 2. In the case of an aramid fiber 2 having a staple or pulp shape, phenol resins are used. Specifically, when products requiring heat resistance, such as fire-resistant clothes, heat-resistant clothes, and the like, are produced, phenolic cashew resins are used, and when products requiring tensile strength and pressure resistance, such as joint sheets, brake lining hoses, conveyor belts, and the like, are produced, phenolic rubber resins are used, and when products requiring high strength, such as adhesive reinforcing agents, molding reinforcing materials, and the like, phenolic epoxy resins or phenolic urethane resins are used.
[26] Further, an aramid fiber having a filament shape is used to produce bulletproof vests, lining additives and thermal insulation materials. In this case, silicon resins are used.
[27] The phenol resins and silicon resins are selectively put into an impregnation furnace filled with a volatile solvent, such as alcohol, toluene, or the like, depending on the use of an aramid fiber 2, and then applied on the surface of the aramid fiber 2 having a staple, pulp or filament shape.
[28] In this case, the thickness of the synthetic resin 1 applied on the aramid fiber 2 having a staple or filament shape is 1 — 20% of the diameter of the aramid fiber 2. Further, the amount of the synthetic resin 1 applied on an aramid fiber 2 having a pulp shape is 1 — 20% by weight of that of the aramid fiber 2.
[29] In the case where the aramid fiber 2 is to be coated with different synthetic resins 1 depending on the shape and use of the aramid fiber 2, as described above, when the aramid fiber 2 is immersed into an impregnation furnace filled with a coating solution including a volatile solvent, such as alcohol, toluene, or the like, and the corresponding synthetic resin 1 and is then taken out from the impregnation furnace, the surface of the aramid fiber 2 coated with the coating solution is wet. Therefore, the aramid fiber 2 coated with the coating solution is primarily dried at a temperature of 6O0C for 1 hour using hot air to volatilize the volatile solvent.
[30] After the primary drying of the aramid fiber 2, in order to completely dry the aramid fiber 2, the aramid fiber 2 is secondarily dried for 4 hours. The secondary drying of the aramid fiber 2 is conducted by passing the aramid fiber 2 through a heat treatment furnace, the temperature of which is sequentially increased from 8O0C to 22O0C. Specifically, the heat treatment furnace is a drier provided with a passage having a predetermined length. The temperature of the inlet of the passage, into which the aramid fiber 2 is introduced, is about 8O0C, and the temperature of the heat treatment furnace is sequentially increased while passing the passage, and the temperature of the outlet of the passage is about 22O0C, so that the aramid fiber passing through the heat treatment furnace is gradually dried.
[31] When the synthetic resin 1 remaining on the surface of the secondarily dried aramid fiber 2 is dried and hardened, the surface of the aramid fiber 2 is also hardened due to the dried synthetic resin 1, and thus the aramid fiber 2 is easily pulverized and cut.
[32] Meanwhile, a conventional aramid fiber is problematic in that it is not easily dispersed and thus is conglomerated due to an electrostatic phenomenon. This problem can be solved by coating the aramid fiber with the synthetic resin and thus preventing the electrostatic phenomenon. Therefore, even when the aramid fiber is pulverized into powder, the electrostatic phenomenon does not occur, and thus the aramid fiber can be easily dispersed. Accordingly, when products are produced using the aramid fiber, the aramid fiber is not conglomerated and thus is uniformly dispersed in the products, thereby remarkably decreasing the defective fraction of products caused by the conglomeration of the aramid fiber.
