Description

  The present invention relates to clothing, and more specifically, to clothing having a function suitable for wiping off dirt adhered to a screen of a smart watch, a wristwatch, or the like.

  In recent years, a wristwatch type wearable terminal called a smart watch has been developed and rapidly spread. Smart watches can communicate with smartphones and the like, have various functions, and are expected to become more popular in the future.

  The smartwatch is operated by attaching it to the wrist like a wristwatch and directly touching the screen as a touch panel with the opposite finger.

  However, since the screen is directly operated by a finger, sebum or the like adheres to the screen, and the screen becomes dirty immediately, making it difficult to see the screen, or causing defects such as poor appearance. In order to remove such adhering dirt, there is a method of wiping with a wiping cloth or the like such as eyeglass wiping, or by rubbing against worn clothing or the like.

  The method of wiping with a wiping cloth such as eyeglass wiping can easily remove dirt, but it is inconvenient because the wiping cloth must always be carried around. In addition, the method of wiping off dirt with the worn clothes has problems such as the clothes becoming dirty, the dirt being unable to be removed cleanly depending on the material of the clothes, and the appearance of wiping with the clothes being unsightly.

  As described above, there is no method for easily and cleanly removing the dirt adhering to the screen of a smart watch or the like.

  Conventionally, there has been proposed a garment attachment that can be attached to and detached from the inside of a release portion that comes into contact with the skin and becomes noticeable on the heel and cuffs of clothing (see Patent Document 1).

  Separately, an adhesive application cloth that can be attached to the neck or wrist of a cutter shirt, wristwatch, etc., to absorb sweat or rash, and to prevent damage and deodorization of clothes has been proposed. (See Patent Document 2).

  In addition, a shirt has been proposed in which a collar including a collar or a base collar is detachable from a shirt body, such as a collar (see Patent Document 3).

  Further, a garment is proposed in which a water-absorbing material article is attached to an outer surface of a sleeve or an outer surface of a front body of the garment that can be stretched and contracted on a wearer's face (see Patent Document 4).

  However, all of these conventional proposals are proposals that take into consideration the wearer's own skin, face, etc., and easily and cleanly remove the dirt adhering to the screen of the smart watch as described above. It is not a proposal intended.
