Description

Clothing

The present invention relates to clothing, and more particularly, to clothing provided with a function suitable for erasing dirt adhering to the screen of a smart watch, wrist watch, or the like.

In recent years, watch-type wearable terminals called smart watches have been developed and rapidly spread. Smart watches can also communicate with smart phones, etc., and have a variety of functions, so it is believed that they will be further popularized in the future.

The operation method of the smart watch is to wear it on the wrist like a wristwatch, and directly touch the screen of the touch panel with the finger on the opposite side of the wearer to perform the operation.

However, since the screen is directly operated by fingers, sebum or the like adheres to the screen, quickly becomes dirty, and it becomes difficult to see the screen, or defects such as unsightly appearance occur. In order to remove such adhering dirt, there may be a method of erasing with a cloth such as eyeglass wipes, or removing it by wiping clothes or the like.

The method of erasing with a cloth such as eyeglass wipes can easily remove dirt, but it is inconvenient to always carry the cloth with you. Also, with the clothes you wear to remove dirt, some clothes become dirty , Or the problem that the dirt cannot be cleanly removed due to the material of the clothes, and the behavior of wiping with the clothes is not beautiful.

As such, the actual situation is that there is no simple and clean method to remove dirt adhering to the screen of a smart watch or the like until now.

In addition, there has been proposed a clothing accessory which can be attached to and detached from a collar or cuff of clothes, etc., and contacts the skin, and the inside of the open part where dirt is conspicuous (refer to Patent Document 1).

In addition, there is another proposal for a close-fitting cloth with an adhesive, which can be installed on the neck part or wrist part of an open shirt or a watch, etc., to prevent the absorption of sweat or rash, and even prevent the damage or elimination of clothing. Odor etc. (refer to Patent Document 2).

In addition, there is proposed a shirt that can freely attach and detach a collar or the like, which can freely attach and detach a collar or a collar including a collar portion to the shirt body (refer to Patent Document 3).

In addition, there is proposed a garment which is a garment formed by attaching an absorbent article to the outer surface of the sleeve or the outer surface of the front body of the aforementioned garment that can be stretched to the face of the wearer (see Patent Document 4).

However, these conventional proposals are all proposals that concern the dirt of the wearer's own skin or face, and are not proposals for simply and cleanly removing the dirt adhering to the screen of a smart watch or the like as mentioned above.
