DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] A first embodiment of the functional textile product of the present invention will be described below with reference to Figures 1 and 2. The functional textile product 10 of this embodiment is suitable for innerwear (undergarments, underwear), for example, and has a liquid emulsion 14 component mainly composed of Job's tears extract extracted from Job's tears seeds and other parts of Job's tears fixed over almost the entire product body 10a, and this component contains oil and fat components such as oleic acid, linoleic acid, palmitic acid, and stearic acid from Job's tears bran oil, coixenolide and coixol. The product is characterized in that the bioactive effects of coixenolide and coixol are obtained by the contact of the above components with the skin of the user.

[0014] As shown in FIG. 1, the functional textile product 10 is manufactured by first cutting a textile fabric 12 (for example, a woven fabric or knitted fabric) into a plurality of parts, which are then assembled and sewn together to form a product body 10a.

[0015] Furthermore, a liquid emulsion 14 containing Job's tears extract as a main component is used to manufacture the functional textile product 10. The liquid emulsion 14 is prepared by emulsifying Job's tears extract with an emulsifier and then adding a diluent such as water to make it liquid, as shown in Fig. 2. The emulsifier is a nonionic surfactant such as glycerin fatty acid ester, sorbitan fatty acid ester, polyoxyethylene alkyl ether, ethylene oxide-propylene oxide block copolymer, alkylamine oxide, etc., and other suitable surfactants can be used.

[0016] Job's tears extract contains Job's tears bran oil, coixenolide and coixol, which have oil and fat components such as oleic acid, linoleic acid, palmitic acid and stearic acid extracted from Job's tears seeds. Job's tears bran oil is an oil extracted from the bran when Job's tears seeds are refined. Coixenolide and coixol are medicinal ingredients extracted in large amounts from the outer skin and Job's tears seed (seed), and have excellent physiologically active effects such as whitening effect, skin roughness prevention effect and allergy suppression effect.

[0017] After preparing the product body 10a and the liquid emulsion 14, the liquid emulsion 14 is attached to the fibers constituting the product body 10a by a dipping method, a spraying method, etc. Then, when this is dried to remove the volatile components of the liquid emulsion 14, the components of the liquid emulsion 14 (oil and fat components such as oleic acid and linoleic acid of Job's tears bran oil, coixenolide, coixol, etc.) are fixed to the fibers constituting the product body 10a, and the functional fiber product 10 is completed.

[0018] The surfactant used to form the liquid emulsion 14 is preferably one that forms the finest micelles, so that the components of the liquid emulsion 14 are firmly fixed (physically adhered) to the surface of the fibers that make up the product body 10a. In fact, when several types of functional fiber products 10 were prototyped and subjected to washing tests, the results showed that the above-mentioned components (oil and fat components of Job's tears bran oil, coixenolide, coixol, etc.) were less likely to fall off than when microcapsules were attached. Furthermore, the washing tests also revealed that the components were more firmly fixed when the material of the product body 10a was a lipophilic material such as polyester.

[0019] As described above, the functional textile product 10 can obtain excellent physiological activity effects due to the medicinal ingredients of Job's tears, coixenolide and coixol, in a good and stable manner. Moreover, the oil and fat components of Job's tears bran oil, such as oleic acid, linoleic acid, palmitic acid, and stearic acid, can obtain moisturizing and protective effects on the skin, and furthermore, the textile fabric and the functional textile product are finished with a very smooth, moist, and excellent texture. Moreover, the manufacturing method shown in FIG. 1 can easily manufacture the functional textile product 10 having the above-mentioned excellent properties.

[0020] Next, a second embodiment of the functional textile product of the present invention and a first embodiment of the functional textile fabric of the present invention will be described with reference to Fig. 3. The functional textile product 16 of this embodiment is a textile product in which a functional textile fabric 18 is used in a specific area that comes into contact with the skin of the user. The functional textile fabric 18 has a fabric body 18a to which components of a liquid emulsion 14 containing as its main component Job's tears extract extracted from Job's tears seeds are fixed, and these components contain oils and fats such as oleic acid, palmitic acid, stearic acid, and linoleic acid from Job's tears bran oil, as well as coixenolide and coixol. When the components come into contact with the skin of the user, the physiological activity effects of coixenolide and coixol are obtained.

[0021] 3, in manufacturing the functional fiber product 16, first, a fabric body 18a (e.g., a woven fabric or a knitted fabric) and the above-mentioned liquid emulsion 14 are prepared. Then, the liquid emulsion 14 is attached to the fibers constituting the fabric body 18a by a dipping method, a spraying method, or the like, and then dried to remove the volatile components of the liquid emulsion 14. In this way, the components of the liquid emulsion 14 (oil and fat components of Job's tears bran oil, coixenolide, coixol, etc.) are fixed to the fibers constituting the fabric body 18a, and the functional fiber fabric 18 is completed.

[0022] Thereafter, the functional fiber fabric 18 and other fiber fabrics (general woven fabrics, knitted fabrics, etc.) are cut to produce a plurality of parts, which are then assembled and sewn together to complete the functional fiber product 16.

[0023] As in the above embodiment, the functional fiber product 16 and the functional fiber fabric 18 can obtain excellent physiological activity effects due to the medicinal ingredients of Job's tears, coixenolide and coixol, in a good and stable manner. Moreover, the oil and fat components of Job's tears bran oil, such as oleic acid, linoleic acid, palmitic acid, and stearic acid, can obtain skin moisturizing and protective effects, and the fiber fabric and the functional fiber product are finished with a very smooth, moist, and good texture. Moreover, the manufacturing method shown in Figure 3 can easily manufacture the functional fiber product 16 and the functional fiber fabric 18 having the above-mentioned excellent performance.

[0024] Next, a third embodiment of the functional fiber product of the present invention, a second embodiment of the functional fiber fabric of the present invention, and a first embodiment of the functional fiber of the present invention will be described with reference to FIG. 4. The functional fiber product 20(1) of this embodiment is a fiber product in which a functional fiber fabric 22 is used in a specific area that comes into contact with the skin of the user, and the functional fiber fabric 22 is a woven or knitted fabric made of functional fiber 24. The functional fiber 24 has a component of a liquid emulsion 14, the main component of which is a Job's tears extract extracted from Job's tears seeds, fixed in the fiber body 24a, and this component contains oil and fat components such as oleic acid, linoleic acid, palmitic acid, and stearic acid of Job's tears bran oil, coixenolide, and coixol. The component is characterized in that the bioactive effect of coixenolide and coixol is obtained by contacting the user's skin with the above-mentioned components.

[0025] As shown in Fig. 4, the functional fiber product 20(1) is manufactured by first preparing a fiber body 24a or a yarn obtained by twisting the fiber body 24a, and the liquid emulsion 14. The liquid emulsion 14 is then attached to the fiber body 24a by using a dipping method, a spraying method, or the like, and dried to remove the volatile components of the liquid emulsion 14. This causes the components of the liquid emulsion 14 (oil and fat components of Job's tears bran oil, coixenolide, coixol, etc.) to be fixed to the fiber body 24a, and the functional fiber 24 is completed.

[0026] Thereafter, the functional fiber fabric 22 is formed using the functional fiber 24. Then, the functional fiber fabric 22 and other fiber fabrics (general woven fabrics, knitted fabrics, etc.) are cut to produce a plurality of parts, which are then assembled and sewn together to produce the functional fiber product 20(1).

[0027] Moreover, the functional fiber product 20(2) in FIG. 4 is a sweater or the like knitted only with thread formed from the functional fiber 24, and in this case, cutting of parts is not required.

[0028] The functional textile products 20(1), 20(2), functional textile fabric 22, and functional textile 24, like the above embodiment, can obtain excellent physiological activity effects due to the medicinal components of Job's tears, coixenolide and coixol, in a good and stable manner. Moreover, the oil and fat components of Job's tears bran oil, such as oleic acid, linoleic acid, palmitic acid, and stearic acid, can obtain skin moisturizing and protective effects, and the textile fabric and functional textile products are finished with a very smooth, moist, and good texture. Moreover, the manufacturing method shown in FIG. 4 can easily manufacture the functional textile products 20(1), 20(2), functional textile fabric 22, and functional textile 24 with the above excellent performances.

[0029] Next, a fourth embodiment of the functional fiber product of the present invention, a third embodiment of the functional fiber fabric of the present invention, and a second embodiment of the functional fiber of the present invention will be described with reference to FIG. 5. The functional fiber product 26(1) of this embodiment is a fiber product in which a functional fiber fabric 28 is used at a specific position that touches the skin of the user, and the functional fiber fabric 28 is a woven or knitted fabric made of a functional fiber 30. The functional fiber 30 is a chemical fiber fiber body 24a kneaded with a liquid emulsion 14x component mainly composed of Job's tears extract extracted from Job's tears, and this component contains oil and fat components such as oleic acid, linoleic acid, palmitic acid, and stearic acid of Job's tears bran oil, coixenolide, and coixol. The bioactive effect of coixenolide and coixol is obtained by the above-mentioned components coming into contact with the skin of the user.

[0030] 5, the functional fiber product 26(1) is manufactured by first preparing resin pellets 32, which are the material for the fiber body of the functional fiber 30, and a liquid emulsion 14x. The liquid emulsion 14x may have the same composition as the liquid emulsion 14 described above, but it is preferable to appropriately adjust the amount of the diluent.

[0031] Once the resin pellets 32 and the liquid emulsion 14x are prepared, the resin pellets 26 are melted and kneaded with the liquid emulsion 14x, and then spun into fibers, resulting in a functional fiber 30 in which the components of the liquid emulsion 14x (oil and fat components of the Job's tears bran oil, coixenolide, coixol, etc.) are fixed.

[0032] Thereafter, the functional fiber fabric 28 is formed using the functional fiber 30. Then, the functional fiber fabric 28 and other fiber fabrics (general woven fabrics, knitted fabrics, etc.) are cut to produce a plurality of parts, which are then assembled and sewn together to produce the functional fiber product 26(1).

[0033] Moreover, the functional fiber product 26(2) in FIG. 5 is a sweater or the like in which only the functional fiber 30 is knitted, and in this case, cutting of parts is not required.

[0034] The functional textile products 26(1), 26(2), functional textile fabric 28, and functional textile 30, like the above embodiment, can obtain excellent physiological activity effects due to the medicinal components of Job's tears, coixenolide and coixol, in a good and stable manner. Moreover, the oil and fat components of Job's tears bran oil, such as oleic acid, linoleic acid, palmitic acid, and stearic acid, can obtain moisturizing and protective effects on the skin, and the textile fabric and functional textile products are finished with a very smooth, moist, and good texture. Moreover, the manufacturing method shown in FIG. 5 can easily manufacture the functional textile products 26(1), 26(2), functional textile fabric 28, and functional textile 30 with the above-mentioned excellent performances.

[0035] Comparing the above-mentioned two functional fibers 24 and 30, the functional fiber 24 (Fig. 4) has a feature that the components of the liquid emulsion 14 are fixed to the surface of the fiber body 24a, and the medicinal components come into direct contact with the skin of the user, so that it can obtain very strong efficacy. On the other hand, the functional fiber 30 (Fig. 5) has a feature that the components of the liquid emulsion 14x are kneaded and fixed in the fiber, so that the medicinal components hardly fall off even after repeated washing, and the efficacy can be maintained for a very long period of time. Therefore, which form to use can be selected by considering the type of functional fiber product, which is the final product, and how it is used.

[0036] The functional fiber, the functional fiber fabric, and the functional fiber product of the present invention are not limited to the above embodiment. For example, the material of the fiber or the thread formed from the fiber, which is the object to which the liquid emulsion is attached, is preferably a lipophilic material such as polyester that provides high adhesion, but may be other materials if the conditions are met. In addition, the type of fiber fabric may be not only woven fabric or knitted fabric, but also nonwoven fabric. Nonwoven fabric is preferable when used for diapers, pants, masks, etc. that come into contact with the skin, as it exerts the above-mentioned action and effect.

[0037] Furthermore, the type of surfactant used to emulsify the Job's tears extract is not particularly limited, and can be appropriately selected according to the type of material, such as fibers, to which the liquid emulsion is to be attached, and the like, and the like. Chemicals, such as rose or other aromatic components, antibacterial agents, etc., may be added to the Job's tears extract to be emulsified. The method of integrating multiple parts in the above description of the embodiment is not limited to sewing, and other methods, such as adhesion and welding, may be used.

[0038] In addition, the present invention can be applied to various textile products that come into contact with the user's skin, and is particularly suitable for clothing such as undergarments, underwear, socks, sports underwear, leggings, spats, leg warmers, arm warmers, scarves, gloves, etc., as well as bedding such as sheets and pillowcases, towels, etc. [Explanation of symbols]
