Abstract

<P>PROBLEM TO BE SOLVED: To provide a magnetized material that can stably put on a complicatedly curved three-dimensional surface of a human body or the like without uncomfortableness. <P>SOLUTION: Magnetic fine powder 1 having a particle size of about 1 to 10 μm, and is preferably made of iron (ferrite) is mixed with fiberizable synthetic resin material 2 in an amount of about 1 to 10%, then extruded out from nozzles to form filaments. In addition, the filaments are used to apply strong magnetic fields to fabrics and obtain magnetized product. By using the filaments, a magnetized secondary products is obtained, which is capable of being put on with the same feeling as that of normal fabrics. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to a filament (single fiber) and fabrics (including yarns) that can be immediately magnetized as needed.

  As is well known, various patch materials, coating materials, special bonds, and the like are used to relieve muscle pain and other symptoms. One of them is to apply the ointment directly to the skin or apply it to the gauze, but recently, a magnetic powder such as ferrite is mixed in the ointment and applied. Attempts have been made to give a magnetic field to the affected area in a planar manner by magnetizing.

  The present inventor has already tried various patch materials mixed with such a magnetic powder. In actual use, however, the application of the ointment is considerably troublesome, and the magnetic powder generally exhibits a black color. For this reason, there were problems such as smearing the surroundings as if painting, and the stains not easily falling off.

  Therefore, the present inventor, in order to provide a magnetizable patch that does not require application work at the time of use and does not stain the periphery, the front and back layers are made into a cloth-like material, and the intermediate layer is made of an elastomer mixed with magnetic powder. A sandwich-like sheet was devised and created, and it was evaluated to some extent.

  However, such a sheet-like material is suitable for laying on a flat surface or wrapping around a cylindrical surface, but it is a serious problem in applying it so as not to deviate from a complicated three-dimensional curved surface like a human body. It was. Accordingly, it is an object of the present invention to provide a magnetic body that eliminates such problems and can be stably mounted on a necessary part of the human body without a sense of incongruity.

  First, the synthetic fiber raw material 2 mixed with the magnetic fine powder 1 is made into a filament (single fiber). The magnetic material may be a known material such as iron (ferrite), nickel, or neodymium, but ferrite is preferred from the viewpoint of cost and workability. The particle size is generally about 1 to 10 μm, which is a fiber such as polyester, recycled PET resin, or rayon raw material (in this application, it is also included in the category of synthetic fiber raw material 2). About 1 to 10% is mixed in a synthetic fiber raw material that can be converted, extruded from a fiber generating nozzle, and fiberized by a known means.

  Fabric processing using this filament yields a variety of fabrics ranging from yarn and even fabrics to all garments. Such fabrics can be formed into various forms suitable for the body without any sense of incongruity, as well as well-known clothes, etc., and at the same time, finished in a form that can be easily worn on the body.

  Since the textiles such as clothes that have been finished in this way are transformed into a textile product with magnetism by applying a strong magnetic field to the textiles, it should be made to meet the intended purpose as described above. it can.

  According to the present invention, since the magnetized body can be made into a secondary product with almost the same feeling as that of ordinary fabrics, it is easy for the user to give magnetism to the desired part of the body for a long time without any discomfort. Thus, there is a great effect that the application range can be remarkably expanded.

  Synthetic fiber polyester is mixed with about 5 W% of ferrite powder having a particle size of about 1 to 3 μm to form a filament with a thickness of about 10 μm by an existing fiberization process. Using this, it is processed into a non-woven fabric, or processed into a yarn or woven fabric, and further processed into various supporters or clothing according to the purpose. Thereafter, the whole or the main part of the cloth is magnetized using an electromagnet or a neodymium magnet to produce a product.

  The finished product, like the existing sandwich-structured magnetic sheet, has a mild magnetic surface, has a thinner (lighter) thickness (lighter) and breathable, almost in any three-dimensional shape. The secondary processing is possible, it was finished to fit the individual human body, and the magnetic decay rate was found to be less than 1% per month. By the way, the prototype was very popular with people who suffered from pain and poor circulation.

  Since the magnetizable fabrics of the present invention greatly improve the existing concept of magnetic care therapy and there is a great need, the production can be sufficiently mass-produced with the existing fiber technology, It can be said that there is sufficient industrial applicability.
