BRIEF DESCRIPTION OF THE DRAWINGS FIG.
Specific embodiments of the present invention will be described.

FIG. 1 shows a cloth obtained by cutting a suit to which the present invention is applied from a pattern, wherein A ₁ and A ₂ denote left and right front bodies and B
Is a back body, and is usually provided with pocket portions P ₁ and P ₂ on the back surface of the left and right front bodies A ₁ and A ₂ , and a pocket portion P ₃ for accommodating a portable telephone as needed.

FIGS. 2 to 4 show the manner in which the pockets are attached to the above-mentioned suit fabric. Reference numeral 1 denotes an outer fabric, 2 denotes a lining, and 3 denotes a pocket P forming cloth. In the structure shown in FIGS. 1, an interlining 6 is layered on the inner surface,
Then, a pocket P is formed by arranging the pocket forming cloth 3 and sewing the saddle stitching tape together with the pocket bag. In FIG. 4, an inner cloth 7 is further interposed on the inner surface of the interlining 6 on the inner surface of the outer material 1.

The pocket is sewn on the backing cloth 4 and then the backing cloth 5 is interposed, and the backing cloth 5 is provided in a required spread including the mounting position of the pocket. A pocket P having a bead at the opening is formed by applying the P forming cloth 3. The backing cloth 5 is appropriately sewn at a required position by a sewing machine or together with the forming cloth of the pocket P. In the drawing, each dotted line indicates a sewing stop portion. Moreover, further insert the portable phone under the normal inner pocket 2, separately convenient pockets P ₃ to house, they are making.

According to the present invention, in the pocket of the above-mentioned garment, in particular, the electromagnetic wave shielding fiber contains less than 20% by weight of the synthetic fiber and the natural fiber as the pocket forming cloth 3 itself in the constituent fiber, and is dispersed almost uniformly. Fiber fabric is used. In this case, the electromagnetic wave shielding fiber is 20% by weight.
It is not preferable to wrap the above with a fiber cloth dispersed over the entire surface, because it is impossible to make a call to the mobile phone as described above and the reception is hindered. Of course, if the amount is too small, it may hinder the performance of the electromagnetic wave shielding effect.
It is suitable that the content is at least about 10% by weight, preferably about 10% by weight or more. The fiber fabric is usually a woven fabric by weaving, a knitted fabric by knitting or a non-woven fabric, and the content of the electromagnetic wave shielding fiber is substantially the same as the weaving, the driving of warp or weft during knitting, the arrangement, and the arrangement of the knitting yarn. It can be formed by considering it to be less than 20% by weight over the entire surface, or can be obtained by determining the blending at the time of forming the nonwoven fabric and blending.

Further, the present invention is not limited to the above-mentioned pocket forming cloth 3, and furthermore, any one or both of the backing cloth 5 and the inner cloth 7 contains less than 20% by weight of the above-mentioned electromagnetic wave shielding fiber. It is also possible to use the combination with the electromagnetic wave shielding effect of the pocket forming cloth 3 itself to further prevent the electromagnetic wave from entering the body. In this case, when the pocket P is sandwiched by both the backing cloth 5 and the inner cloth 7, the electromagnetic wave of the two cloths 5 and 7 can be generated by the synergistic effect of the two cloths 5 and 7, especially without using the pocket as the cloth containing the electromagnetic wave shielding fiber. It is possible to prevent entry into the body. Since the backing cloth 5 is on the side facing the body, the electromagnetic wave shielding fiber is not limited to less than 20% by weight, but may be more than 20% by weight and may have a high electromagnetic wave shielding property.

Here, the electromagnetic wave shielding fibers include at least one selected from metal fibers and organic conductive fibers. Particularly, as the organic conductive fibers, for example, silver or carbon black fine powder is added to the surface of synthetic fibers. Coated (trade name Metalian), synthetic fiber knitted fabric chemically plated with silver, and then deknitted (trade name X-
static), a seed core fiber containing carbon black as a core component, a metal-deposited slit yarn, and the like. Particularly, the above-mentioned two in which synthetic fibers are plated or coated with silver are the most practical. In particular, the use of a textile made of silver chemically plated fibers is most advantageous.

The pocket P is not limited to a pocket having a bead opening, but may be a pocket having a rain cover. In this case, it is preferable that the rain cover is also formed of a fiber cloth containing electromagnetic wave shielding fibers. It is.

Although the above description has been given by taking a suit pocket as an example, applicable clothing can be similarly applied as long as it has a pocket and inserts and stores a mobile phone or the like in the pocket. , Jacket, casual wear,
The present invention can be applied not only to the upper garment such as a blazer or a coat, but also to the pants or the like.
