  ADVANTAGE OF THE INVENTION According to this invention, the cloth for textiles for the treatment by a magnetic field and excellent in a softness | flexibility and textiles are obtained.

In this invention, it is a figure which shows typically the aspect by which the conductive resin or the metal is adhere | attached in the coil shape. In this invention, it is a figure which shows typically the aspect by which the conductive fiber is knitted.

  Hereinafter, embodiments of the present invention will be described in detail. First, the fabric of the present invention is a fabric for treating with a magnetic field. The disease or disease to be treated is not particularly limited, and examples thereof include cancer, heart disease, stiff shoulders, back pain, headache and the like.

In the first aspect of the present invention, a conductive resin or metal is fixed to the fabric surface. The conductive resin or metal may be fixed on both sides of the fabric, but is preferably fixed on one side. Further, the conductive resin or metal may be directly fixed to the fabric, or may be indirectly fixed.
For example, it is preferable that a resin is laminated on a fabric and a conductive resin or metal is fixed on the fabric without being transmitted to the opposite surface of the fabric. In this case, urethane resin is preferable as the resin because the flexibility of the fabric is not impaired.

The conductive resin is preferably a resin having a resistance value of 10 −4 Ω / cm ² or less (more preferably 1 × 10 −6 to 1 × 10 −4 Ω / cm ² ). As such a conductive resin, those containing silver, copper, or carbon such as silver paste, copper paste, and carbon paste are preferable. Examples of commercially available products include “Dotite” (trade name) manufactured by Fujikura Kasei Co., Ltd. At that time, the fixing method may be normal printing.

Further, a metal such as silver or copper may be directly fixed to the fabric by a method such as vapor deposition.
Here, the application pattern of the conductive resin or metal is not particularly limited, and may be any pattern.
For example, a coiled pattern as shown in FIG. 1 is preferable because a magnetic field is easily generated from the front to the back (back to front) of the body by energizing the conductor.

Moreover, as a fabric, the fabric of 50-250 g / m < ² > is preferable. If the weight per unit area is greater than 250 g / m ² , the weight of the garment becomes heavy and the wearing comfort may be reduced. Conversely, if the basis weight is less than 50 g / m ² , the fabric strength may be reduced.
Moreover, it is preferable that the elongation measured by the JIS L1096-2010 8.16.1 B method is 1% or more (more preferably 10 to 40%) in the vertical direction or the horizontal direction of the fabric. If the elongation is less than 1%, flexibility may be reduced.

It is preferable that the fabric includes crimped fibers, elastic fibers, or composite fibers in which two components are bonded to each other in a side-by-side type or an eccentric core-sheath type because stretch properties are improved. At that time, as the crimped fiber, a false twist crimped yarn is particularly preferable. As the elastic fiber, polyurethane fiber or polyether ester fiber is preferable.

  In the crimped fiber, elastic fiber, or composite fiber in which two components are bonded in a side-by-side type or an eccentric core-sheath type, the single fiber fineness is 2.3 dtex or less (preferably 0.00002 to 2.0 dtex, particularly It is preferably 0.1 to 2.0 dtex). The smaller the single fiber fineness is, the better, and the single fiber diameter called nanofiber may be 1000 nm or less. Such fibers are preferably multifilaments having a total fineness of 33 to 220 dtex and a filament number of 50 to 300 (more preferably 100 to 300).

  In addition, the single fiber cross-sectional shape of the crimped fiber, the elastic fiber, or the composite fiber in which the two components are bonded to the side-by-side type or the eccentric core-sheath type may be a normal round cross section, but an irregular shape other than the round cross section It may have a cross-sectional shape. Examples of such irregular cross-sectional shapes include triangles, squares, crosses, flats, flats with constrictions, H-types, and W-types. At that time, the cross-sectional flatness expressed by the ratio B / C1 of the flat cross-sectional shape with the length B in the longitudinal centerline direction to the maximum width C1 in the direction perpendicular to the longitudinal centerline direction is 2 It is preferable in terms of the softness of the fabric to be in the range of ˜6 (more preferably 3.1 to 5.0). In addition, the water absorption of the fabric is such that the ratio C1 / C2 of the maximum value C1 of the width to the minimum value C2 is in the range of 1.05 to 4.00 (more preferably 1.1 to 1.5). From the viewpoint of sex.

And the first stage reaction to produce a glycol ester of terephthalic acid and / or its low polymer, and the first stage reaction product is heated under reduced pressure until the desired degree of polymerization is reached. It may be produced by a second stage reaction for condensation reaction. The polyester is a material-recycled or chemical-recycled polyester, or a catalyst containing a specific phosphorus compound and a titanium compound as described in JP-A-2004-270097 and JP-A-2004-212268.
