Description

  The present invention relates to an underwear knitted fabric that is thin, light and excellent in heat retention, and an undergarment using the same.

  In general, when working outdoors or watching sports or watching sports in the cold season, a lot of clothing such as thick underwear and sweaters are layered, so there is a problem that these clothes are bulky and the wearer is difficult to move. It was. In addition, it was cold when commuting or going out, but it was warm in the office and in the car, so it was not possible to wear thick clothes and often put up with the cold in thin clothes.

  On the other hand, as a conventional technique related to clothing with improved heat retention, underwear for dermatitis patients (for example, two layers of fabric using pure cotton cloth on the outer surface and gauze cotton cloth on the back surface) In this underwear, a glove consisting of a thumb, forefinger, and other three fingers together is continuously formed, and a belt is attached to the abdomen so that a dermatitis patient can receive skin. It was devised so as not to hurt, and was generally not usable.

  Also known is a garment (for example, Patent Document 2) having a heat retaining part made of a material or structure having a high heat retention rate only in a portion where heat insulation is desired, but this garment divides the body into several lines. However, because it is necessary to connect the high heat insulation material and the part that does not fit to the line, it requires not only troublesome means such as changing the knitting gauge and sewing the patch, but also the wearer Due to the body shape and operation, the high temperature insulation part was removed from the divided line, and the original purpose could not be sufficiently achieved.

Furthermore, there is also proposed a backless underwear (for example, Patent Document 3) in which only the waist portion of the back portion is doubled and a heat insulating agent can be put in that portion. It is longer than the front body and has a pocket part, and the warmth of the back is partially improved, but it not only warms the whole body, but also has a pocket partly, On top of that, wearing a thin jacket would make it bulky and inferior in appearance.
