[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a fiber product and a surface treatment method for fibers or fiber materials.
[0002]
[Prior art]
In recent years, weak radiation and negative ions generated from minerals containing rare elements of natural radiation have been shown to be effective in blood purification, tranquilization, bactericidal immunity, lung function enhancement, autonomic nerve regulation, analgesic action, and cell activation. It has been found that it has a useful action on the body such as an action, and has a bactericidal, antibacterial, antibacterial action, deodorizing action and the like. In addition, products utilizing these actions have already been sold and their usefulness is known.
[0003]
Thus, the following method is known as a utilization method of the natural radiation rare element mineral which has a useful effect on a body to a health material and a medical material.
(1) A method for producing synthetic fibers with a material mixed with fine powder of the mineral A method for producing synthetic fibers with a material mixed with fine powder of the surface-modified mineral (Japanese Patent Publication No. 8-8934), hot spring A method for producing a synthetic fiber with a material containing a medical substance (JP-A-5-44157), and a method for producing an acrylic synthetic fiber with a material containing a fine powder of the mineral (JP-A-3-185109) ) Etc.
(2) Method for adhering fine powder of mineral to fiber surface As for the method, fiber containing or adhering animal bone (JP-A-2-74604), resin having adhesive strength to fine powder of mineral Although there is a slight description in the method of mixing and adhering to fabric or the like (Japanese Patent Laid-Open No. 62-32948), it is not described specifically.
[0004]
[Problems to be solved by the invention]
The method (1) has an advantage that the fine powder is difficult to fall off because the fine powder of the mineral is mixed in the fiber. However, it has an adverse effect on the properties of the fiber itself, or it is difficult to respond to changes in fiber types, increase / decrease in demand, etc. because it must plan mixing of the fine powder from the spinning process, or it can not be applied to natural fibers There are drawbacks.
[0005]
Therefore, attention is paid to the method (2) above, but as described above, since it is not specifically clarified by what means the fine powder of the mineral is adhered to the fiber surface, Consideration is necessary. The present inventor has repeatedly studied various adhesive materials, but some of them satisfy one of the conditions that “the fine powder is not easily dropped from the surface of the fiber” and “the texture of the fiber does not deteriorate”. Few things fulfilled both.
[0006]
And what this inventor finally found out as an adhesive material which satisfy | fills both these conditions practically is the polysaccharide obtained from a konjac rice cake. The polysaccharides obtained from konjac koji are starchy like wild nuts, roots, edible bulbs, branches, vines, and other koji, and swell significantly when they contain moisture, and have strong adhesive strength. Because of its strong heat and cold resistance, it has been used for many years. Examples of use for textiles include those used for surface treatment of armor, samurai, etc., starting with clothing of samurai and samurai since the Heian period. For example, it is used to prevent fluffing of paper sheets (Kamiko). It was. However, there is no example used to deposit fine powder of natural radiation rare element mineral as in the present invention.
[0007]
An object of the present invention, by taking the means of a fine powder of natural radiation rare element mineral to the surface of the silk fibers is deposited with coating of polysaccharide extracted from konjac tubers, the fine powder fall off from the surface of the fiber It is an object of the present invention to provide a fiber product that can practically satisfy both the conditions that it is difficult and the texture of the fiber does not deteriorate, and that can continuously obtain various functions and effects of the mineral.
[0008]
