[0008] However, in the fibers in which the above-mentioned microcapsules are dispersed and held, no particular examples have been disclosed in which microcapsules having temperature regulating properties are used.

[0009] Therefore, the present invention has been devised in consideration of the above-mentioned background, and its object is to provide a textile product that can be applied to clothing fabrics, and that has a particularly high thermal conductivity and an improved heat dissipation effect, thereby giving it an advantage in terms of temperature regulating performance. [Means for solving the problem]

[0010] The textile product with temperature regulating properties relating to the first invention is characterized in that microcapsules having a heat storage material and an outer shell encapsulating the heat storage material are dispersed and fixed to a fibrous body.

[0011] The second invention relates to a textile product having temperature regulating properties, which is characterized in that in the first invention, the microcapsules have a heat storage material of octadecane and an outer shell of polyurea resin.

[0012] The textile product having temperature regulating properties according to the third invention is characterized in that in the second invention, the microcapsules have a diameter of 1-5 μm and a pH of 5-7. Effect of the Invention

[0013] According to the present invention having the above-mentioned configuration, microcapsules capable of realizing high thermal conductivity and improving heat dissipation effect are dispersed and fixed in the fibrous body, thereby making it possible to endow the resulting textile product with temperature regulating properties. [Brief description of the drawings]

[0014] [Figure 1]FIG. 1 is a perspective view of a textile product having temperature regulating properties according to the present invention. [Diagram 2] FIG. 2 is a diagram for explaining the structure of a microcapsule. [Diagram 3] FIG. 3 is a diagram for explaining a method for manufacturing a textile product to which the present invention is applied. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. As shown in FIG. 1, a textile product 100 having temperature regulating properties according to the present invention has microcapsules 3 dispersed and fixed to a fibrous body 2.

[0016] The fibrous body 2 may be made of any fiber material suitable for use in clothing fabrics, such as cotton, polyester, wool, silk, linen, nylon, rayon, acrylic, denim, etc. However, the fibrous body 2 is not limited to materials suitable for use in clothing fabrics, and may be made of any other fiber material.

[0017] 2, the microcapsule 3 has a heat storage material 31 and an outer shell 32 that constitutes an outer skin that encapsulates the heat storage material 31. That is, the microcapsule 3 contains the heat storage material 31 in the inner shell portion, and the outer shell portion that encapsulates the outer shell is constituted by the outer shell 32. The microcapsule 3 has a diameter of 1 to 5 μm and is adjusted to have a pH of 5 to 7.

[0018] Such minute microcapsules 3 are randomly dispersed inside and on the surface of the fibrous body 2 and are fixed to the fibrous body 2 so as not to move.

[0019] The heat storage material 31 is made of a material such as octadecane.

[0020] The outer shell 32 is made of a material such as a polyurea resin.

[0021] Table 1 shows the weight ratio (wt%) of the heat storage material 31 and the outer shell 32 that constitute this microcapsule 3. The heat storage material 31 can be classified in detail into a gelling agent, a latent heat agent, and water, and the range of the weight ratio of each of these is as shown in Table 1.

[0022] [Table 1]

[0023] Next, a method for manufacturing a textile product 100 to which the present invention is applied will be described. First, as shown in Fig. 3, an aqueous solution of a processing agent containing microcapsules 3 and a fixing agent 4 is prepared. The fixing agent 4 may be any of the known fixing agent components, such as an epoxy resin adhesive, a polyurethane adhesive, an acrylic adhesive, a rubber-based adhesive, a silicone adhesive, a two-liquid adhesive, etc.

[0024] Next, the fibrous body 2 is immersed in the aqueous solution of the processing agent. In this case, the fibrous body 2 may be immersed in the aqueous solution of the processing agent by dropping the aqueous solution onto the fibrous body 2, or the fibrous body 2 may be immersed in a container (not shown) containing the aqueous solution of the processing agent.

[0025] As a result, the microcapsules 3 in the aqueous solution of the processing agent are randomly dispersed inside and on the surface of the fibrous body 2. The dispersed microcapsules 3 are then fixed to the inside and on the surface of the fibrous body 2 via the fixing agent 4 contained in the aqueous solution of the processing agent. Furthermore, as the fixing agent 4 solidifies on the surface of the fibrous body 2, a coating 41 made of components of the fixing agent 4 is formed on the surface of the fibrous body 2. The formation of this coating 41 allows the textile product 100 itself to have a covering function from the outside. However, the formation of this coating 41 is not essential and may be omitted.

[0026] The textile product 100 thus constructed is made up of a textile body 2 in which microcapsules 3 are dispersed and fixed. The microcapsules 3 and the heat storage material 31 are made of a material such as octadecane. Therefore, the microcapsules 3 can be given temperature control performance by improving the high thermal conductivity and heat dissipation effect exhibited by the octadecane. The textile product 100 can be endowed with temperature control performance via the microcapsules 3 having temperature control performance. Therefore, when the textile product 100 is applied particularly as a fabric for clothing, it can be provided to customers as temperature control clothing that can provide a cool feeling when it is hot and heat dissipation when it is cold.
