Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a far-infrared radiation cloth.

[Conventional technology]

It is well known that far infrared rays promote blood circulation in the human body and have medical effects and health promotion effects, and recently, medical devices and the like using such far infrared rays have been developed, and
The use of far infrared rays has also been introduced in the fields of clothing and bedding. For example, a synthetic resin liquid in which alumina-based, zirconia-based, magnesia-based, or the like ceramic particles are dispersed on raw cotton has been developed by dipping or the like.

[Problems to be solved by the invention]

As described above, the cotton fiber having the ceramic particles adhered to the outer periphery has a high hardness of the ceramic, and the spinning machine,
When it is applied to a stretching machine, a knitting machine, etc., it is worn and damaged, so that it cannot be spun, and it does not feel good on the skin. Therefore, it is only used for futon cotton which does not come into direct contact with the skin. The cotton fiber to which the ceramic particles are attached also has a problem that the ceramic particles are easily detached.

On the other hand, outer garments and the like have been developed in which ceramic particles are attached to the surface of cloth such as woven cloth, thereby improving heat retention. However, since fibers such as cotton fibers to which the ceramic particles are attached cannot be spun and made into a fabric as described above, the outer garment is woven in advance by using the fibers to which the ceramic particles are not attached, and the ceramic particles are included therein. It is manufactured by printing with ink. Thus, the outer garment merely deposits the ceramic particles on the fabric surface. This kind of outerwear is
The soft texture of the fabric itself is impaired by the above-mentioned print printing containing ceramic particles, and the texture is not good enough. As described above, according to the conventional technique, the fabric cannot be manufactured by using the fibers to which the ceramic particles are attached, and the 3 ceramic particles can only be printed and printed on the surface of the fabric. And this cloth has a problem in terms of breathability and hygroscopicity.

The present invention has been made in view of such circumstances, and provides a far-infrared radiation cloth which is comfortable to the skin, has a soft texture of the cloth, does not desorb ceramic particles, and is highly breathable and hygroscopic. To that end.

[Means for solving problems]

In order to achieve the above-mentioned object, the far-infrared radiation cloth of the present invention is a thin fabric in which a synthetic resin liquid containing particles having far-infrared radiation characteristics is projected onto at least one whole surface and then heated and pressed by a heat roller. A non-woven fabric and a pile thread, which is sewn on the surface of the non-woven fabric in a state where the non-woven fabric is inserted in each pile, forms a myriad of piles in a distributed manner.

[Action]

In other words, this invention uses a thin non-woven fabric, which is produced by projecting a synthetic resin liquid containing particles having far-infrared radiation characteristics on one surface, and then applying heat and pressure with a heat roller, so that far-infrared radiation adhering to the surface is used. The particles having the characteristics are pressed into the fibrous structure of the non-woven fabric during the heating and pressing of the hot roller. Therefore, the unpleasant feeling of the skin due to the ceramic particles is improved, and since the whole is compressed and thinned by the heating and pressing of the heat roller as described above, it has the same flexibility as the cloth. It also has the strength of the waist. As a result, it becomes possible to directly sew the pile thread on this. Further, as described above, the ceramic particles,
Since the non-woven fabric is pressed into the fibrous structure, the ceramic particles are not detached during use. Moreover, according to this invention, innumerable piles are formed on the surface of the above thin nonwoven fabric. Therefore,
The pile secures air permeability and hygroscopicity, and the particles existing in the fiber structure of the non-woven fabric emit far infrared rays. Therefore, the far-infrared radiation cloth of the present invention can be used as a material for a blanket, underwear, or the like that comes into direct contact with the skin. In addition, since the non-woven fabric has a good feel on the skin as described above, even if the portion exposed from between the piles directly contacts the skin, there is no discomfort.

Next, examples will be described.
