Referring to FIGS. 1 to 3, first base fibers 110 including ceramic fibers are prepared (S100). According to one embodiment, the ceramic fiber 100 may include any one of basalt fiber, glass fiber, and carbon fiber. The above-described fibers are only exemplary fibers of the ceramic fiber 100, and the ceramic fiber 100 may include various ceramic fibers in addition to the above-described fibers.

A second base fiber 120 provided with functional particles (FP) in the polymer resin fiber 100 is prepared (S200). According to one embodiment, the step of preparing the second base fiber 120 includes preparing a polymer resin, providing the functional particles to the polymer resin to provide a base solution in which the polymer resin and the functional particles are mixed. It may include preparing the second base fiber 120 by melting and then spinning the base solution.

According to one embodiment, for example, the polymer resin fiber 100 may include an engineering polymer resin. Specifically, the polymer resin fiber 100 may include any one of polypropylene (PP) fiber, polyethylene (PE) fiber, and polyamide 6 (PA6) fiber. The above-described fibers are only exemplary fibers of the polymer fiber 100, and the polymer fiber 100 may include various engineering polymer fibers in addition to the above-described fibers.

According to one embodiment, the functional particles (FP) may include titanium oxide (TiO ₂ ). Titanium oxide (TiO ₂ ) has a large oxidizing power, so it can have antibacterial, odor removal, and sterilizing effects, and can also act as a photocatalyst by absorbing ultraviolet rays. In contrast, according to another embodiment, the functional particle (FP) may include zinc oxide (ZnO). Zinc oxide (ZnO) has functions such as high electrical conductivity, high thermal conductivity, UV absorption ability, high temperature stability, neutral pH stability, and antibacterial effect, and is non-toxic, so it can be easily applied to textiles in contact with the human body. In contrast, according to another embodiment, the functional particles (FP) may include aluminum oxide (Al ₂ O ₃ ). Aluminum oxide (Al ₂ O ₃ ) has the characteristics of high electrical insulation, wear resistance, and high chemical stability. The above-described functional particles (TiO ₂ , ZnO, Al ₂ O ₃ ) are merely exemplary functional particles, and the functional particles (FP) may include various metal oxides.

The hybrid fiber 200 can be manufactured by twisting the first base fiber 110 and the second base fiber 120 together (S300). According to one embodiment, the hybrid fiber 200 may be manufactured by twisting the first base fiber 110 and the second base fiber 120 300 times based on the length of the hybrid fiber 100 of 1 m. In contrast, according to another embodiment, the hybrid fiber 200 has the first base fiber 110 and the second base fiber 120 exceeding 300 times, or 300 times, based on 1 m of the hybrid fiber 100 length. It can be manufactured with less twist. That is, the number of times the first base fiber 110 and the second base fiber 120 are twisted is not limited. Additionally, the first base fiber 110 and the second base fiber 120 may be twisted in the S direction or Z direction.

According to one embodiment, the content of the second base fiber 120 in the hybrid fiber 200 may be 1 wt% to 10 wt% compared to the first base fiber 110. Accordingly, the physical strength of the hybrid fiber 200 can be improved by about 20%.

In addition, according to one embodiment, the hybrid fiber 200 is formed by twisting the second base fiber (e.g., polypropylene fiber) of 50 denier and the first base fiber (e.g., basalt fiber) of 630 denier with each other. can be manufactured.

Unlike the above-mentioned, according to another embodiment, the hybrid fiber 200 includes the first base fiber 110, the second base fiber 120, and the third base fiber ( 130) can be manufactured by twisting each other. The third base fiber 130 may include a polymer resin like the second base fiber 120.

Referring to Figures 1 and 5, a hybrid fabric 300 can be manufactured using the hybrid fiber 200 (S400). According to one embodiment, the hybrid fiber 200 may be used as either a warp yarn (WY) or a weft yarn (FY) for manufacturing the hybrid fabric 300. For example, the hybrid fabric 300 may be manufactured by using the hybrid fiber 200 as a warp yarn and the second base fiber 120, that is, a polymer resin fiber, as a weft yarn. Alternatively, in another example, the hybrid fabric 300 may be manufactured by using the second base fiber 120, that is, a polymer resin fiber, as a warp yarn, and the hybrid fiber 200 as a weft yarn. Alternatively, as another example, the hybrid fabric 300 may be manufactured using the hybrid fiber 200 as both warp and weft yarns. In contrast, as another example, the hybrid fabric 300 uses the second base fiber 120, that is, a polymer resin fiber, as a weft, and the first base fiber 110, that is, a ceramic fiber. It can be manufactured using a ramp.

Specifically, the hybrid fabric 300 may be manufactured by using a hybrid fiber of 630 denier basalt fiber and 50 denier polypropylene fiber as a warp yarn, and using 630 denier basalt fiber as a weft yarn. In this case, the hydrid fabric 300 can be manufactured at a density of 44 warp yarns/inch and 35 weft yarns/inch.

The hybrid fabric 300 manufactured as described above not only has improved impregnation with the polymer resin film during the laminating process described later, but also can improve weaving productivity by preventing the pimping phenomenon of ceramic fibers.

After the hybrid fabric 300 is manufactured, a heat press process may be performed on the hybrid fabric 300. The hybrid fabric 300 on which the heat press process was performed may be defined as a ceramic fiber composite. For example, as shown in FIG. 6, the hybrid fabric 300 may be compressed by applying pressure from the top and bottom of the hybrid fabric 300 and the hybrid fabric 300 may be heat treated. Alternatively, after compressing the hybrid fabric 300 by applying pressure from the top and bottom of the hybrid fabric 300, the compressed hybrid fabric 300 may be heat treated.

As described above, when a heat press process is performed on the hybrid fabric 300, the polymer resins of the second base fiber 120 may permeate into the hybrid fabric 300. That is, as the heat press process is performed on the hybrid fabric 300, the polymer resins of the second base fiber 120 may be uniformly dispersed within the hybrid fabric 300. Accordingly, the strength of the hybrid fabric 300 can be improved by the polymer resin.

Alternatively, as another example, as shown in FIG. 7, in a state in which two sheets of the hybrid fabric 300 are overlapped, a heat press process may be performed on the overlapped hybrid fabric 300. Accordingly, the two sheets of hybrid fabric 300 are combined, and the polymer resin of the second base fiber 120 can be uniformly dispersed in the combined hybrid fabric 300. Accordingly, the strength of the hybrid fabric 300 can be further improved.

Referring to FIGS. 1 and 8 , after a heat press process is performed on the hybrid fabric 300, the hybrid fabric 300 may be laminated with the polymer resin film 400 (S300). That is, the ceramic fiber composite can be laminated with the polymer resin film 400. Accordingly, functional hybrid fabrics can be produced.

According to one embodiment, the step of manufacturing the functional hybrid fabric includes preparing the polymer resin film 400, placing the hybrid fabric 300 on the upper and lower portions of the polymer resin film 400, respectively. It may include the step of compressing and heat treating the hybrid fabric 300 and the polymer resin film 400 with a press.

As the hybrid fabric 300 is laminated with the polymer resin film 400, the polymer resin of the polymer resin film 400 may permeate into the hybrid fabric 300. Additionally, as the hybrid fabric 300 is laminated with the polymer resin film 400, the polymer resin of the second base fiber 120 may also permeate into the hybrid fabric 300. That is, as the hybrid fabric 300 is laminated with the polymer resin film 400, the polymer resins of the polymer resin film and the polymer resins of the second base fiber 120 are uniform in the hybrid fabric 300. can be dispersed. Because of this, the strength of the hybrid fabric 300 can be improved.

In addition, as the hybrid fabric 300 is laminated with the polymer resin film 400, the functional particles (FP) of the second base fiber 120 may be dispersed into the first base fiber 110. . That is, the functional particles (FP) of the second base fiber 120 may be uniformly dispersed within the hybrid fabric 300. Accordingly, the functional hybrid fabric 300 can efficiently express the function of the functional particles (FP).

Contrary to what was described above, when a fabric manufactured using general ceramic fibers is laminated with a polymer resin film, the polymer resins of the polymer resin film may not be uniformly dispersed in the fabric, which may result in a decrease in strength improvement efficiency. In addition, when a fabric manufactured using general polymer fibers is laminated with a polymer resin film, a problem may occur in that the weight of the fabric becomes heavy.

In addition, when the functional particles (FP) are not provided in the step of preparing the second base fiber 120, but are provided while the hybrid fabric 300 is manufactured, the functional particles (FP) Since it is not uniformly dispersed within the hybrid fabric 300, the functional expression by the functional particles (FP) may not be easily achieved.

However, the functional hybrid fabric according to an embodiment of the present invention is manufactured by twisting the second base fiber 120 and the first base fiber 110 provided with the functional particles (FP) in the polymer fiber 100. It can be manufactured using the hybrid fiber 200. Accordingly, the functional particles (FP) are uniformly dispersed within the hybrid fiber 200, so that function expression by the functional particles (FP) can be easily achieved. In addition, since the polymer resin is easily dispersed in the process of lamination with the polymer resin film, not only can strength be efficiently improved, but weight reduction can also be achieved by the first base fiber 110.

Above, the functional ceramic fiber composite and its manufacturing method according to an embodiment of the present invention have been described.

When heat treatment is performed as described above, the adhesion between the first base fiber 110 and the second base fiber 120 is improved, so the durability of the hybrid fiber 200 can be improved. Because of this, the durability of the hybrid fabric 300 manufactured using the hybrid fiber 200 can also be improved, and the hybrid fabric 300 can be manufactured more efficiently. In addition, by preventing the pimping phenomenon of ceramic fibers, manufacturing productivity of the hybrid fabric 300 can be improved.

That is, the second base fiber 120 is stretched and twisted with the first base fiber 110, and the first base fiber 110 and the second base fiber 120 are twisted in a twisted state. The hybrid fiber 200 can be manufactured by shrinking the base fiber 120.

When manufactured as described above, the adhesion between the first base fiber 110 and the second base fiber 120 may be improved during the process of shrinking the second base fiber 120. Because of this, the durability of the hybrid fiber 200 can be improved. In addition, the durability of the hybrid fabric 300 manufactured using the hybrid fiber 200 can also be improved, and the hybrid fabric 300 can be manufactured more efficiently.

Method for manufacturing functional ceramic fiber composite according to the third modified example

The manufacturing method of the functional ceramic fiber composite according to the third modified example of the present invention is the same as the manufacturing method of the functional ceramic fiber composite according to the embodiment described with reference to FIGS. 1 to 8, but the first base fiber (110) ) and stepwise heat treatment may be performed in the process of twisting the second base fibers together.

According to one embodiment, heat treatment is performed in the process of twisting the first base fiber 110 and the second base fiber with each other, and the first base fiber 110 and the second base fiber 120 are In the process of twisting up to 1 turn, the first base fiber 110 and the second base fiber 120 are heat treated at a first temperature, and in the process of twisting the first base fiber 110 and the second base fiber 120 up to the second number of times, the first base fiber is heat treated at a second temperature. (110) and the second base fiber 130 may be heat treated at a third temperature in the process of twisting up to a third number of times. The third temperature may be higher than the second temperature, and the second temperature may be higher than the first temperature. Additionally, the third number of times may be greater than the second number of times, and the second number of times may be greater than the first number of times.

Specifically, in the process of twisting the first base fiber 110 and the second base fiber 120 up to 100 times, they are heat treated at the first temperature (lowest temperature), and in the process of twisting them up to 100 to 200 times, the It may be heat treated at a second temperature (a temperature higher than the first temperature), and in the process of twisting 200 to 300 times, it may be heat treated at the third temperature (a temperature higher than the second temperature).

As described above, when stepwise heat treatment is performed, not only can the adhesion between the first base fiber 110 and the second base fiber 120 be improved, but damage to the hybrid fiber 200 can be reduced. there is. On the other hand, when heat treatment is performed once in the process of twisting the first base fiber 110 and the second base fiber 120, the space between the first base fiber 110 and the second base fiber 120 Although the adhesive strength is improved, the hybrid fiber 200 may be damaged and physical and chemical properties may be deteriorated.
