Title: Cleaning Wiper for Glass

Description:
TECHNICAL FIELD 
     This invention relates to a cleaning cloth for glass which is convenient in wiping water moistures, stubborn stains, watermarks, hand stains, fat, and the like of the glass products (hereinafter refer to as ‘glass surfaces’) such as liquid crystal device or glass and the like. 
     BACKGROUND ART 
     Hitherto, in cleaning glass surfaces, eyeglasses are wiped using woven fabrics with smooth surfaces, or cleaned with microfiber cloth as described in the following patent literature. 
     Such a woven fabric or a microfiber cloth wipes water moistures, stubborn stains, watermarks, hand stains, fat, and the like using both surfaces of the single cloth. 
     However, friction between the single piece of cloth and the glass surface is so high that the cloth is being curled instead of being pushed well when wiping therewith by pushing it aside while pressing, thereby cleaning becomes difficult. 
     This principle is similar in that wiping an eyeglass is not possible due to the difficulty in pushing (the cloth) unless (the eyeglass) is wiped while holding it with two fingers when wiping.

     SUMMARY OF INVENTION 
     Technical Problem 
     An objective of the present invention, devised to solve above described problems, is to provide a cleaning cloth for glass that can clean neatly by being pushed well aside because surface friction is smoothed by the air pouring out from the inside thereof while wiping glass surfaces. 
     Solution to Problem 
     To achieve above described objective, a cleaning cloth for glass described in claim  1  of the present invention includes: a first microfiber cloth; a second microfiber cloth; an intervening layer which is interposed between said first microfiber cloth and said second microfiber cloth; and a seam where the edges of said first microfiber cloth, said second microfiber cloth, and said intervening layer are seamed together by sewing; wherein said first microfiber cloth and said second microfiber cloth are tricot woven fabrics, and said intervening layer is comprised of sponge. 
     According to this configuration, it can be cleaned neatly by being pushed well aside because surface friction is smoothed by the air pouring out from the inside thereof while wiping glass surfaces. 
     Advantageous Effects of Invention 
     According to the present invention, there are following effects. 
     By interposing sponge between the first microfiber cloth and the second microfiber cloth, the pressed air in the sponge is pouring out through the lower surface thereof, thereby smoothing the friction with the glass surface such that the cleaning can be performed neatly by being pushed well aside (or back and forth) without curling thereof. 
     Especially since the first microfiber cloth and the second microfiber cloth are tricot woven fabrics weaved by single warp yarns, the flow of the air pouring in and out due to the pressure is satisfactory.

     DETAILED DESCRIPTION OF EMBODIMENT 
     Hereinafter, a preferred exemplary embodiment of the present invention will be described in detail with reference to the accompanying drawings. 
       FIG. 1  is a prospective view illustrating a cleaning cloth for glass according to a preferred exemplary embodiment of the present invention, and  FIG. 2  is a cross-sectional view along the line  2 - 2  in  FIG. 1 . 
     As illustrated in  FIGS. 1 to 2 , a cleaning cloth for glass according to an exemplary embodiment of the present invention includes: a first microfiber cloth  10 ; a second microfiber cloth  30 ; and an intervening layer  50  which is interposed between said first microfiber cloth  10  and said second microfiber cloth  30 . 
     It is advantageous in that especially the first microfiber cloth  10  and the second microfiber cloth  30  are made of tricot woven fabrics weaved by single warp conjugated yarns made of polyester and nylon. 
     Since the tricot fabrics are weaved by warp yarns having multiple rows comprised of uneven surfaces, it allows air to flow minutely between the intervening layer  50  and the outside. 
     Although any elastically deformable solid matter may be used as an intervening layer  50 , a sponge  50  wherein air can breathe well is the most preferred in the exemplary embodiment of the present invention. 
     In addition, a seam  70 , which is seamed by sewing, is formed along the edges of the first microfiber cloth  10 , the second microfiber cloth  30 , and the interposing sponge  50 . 
     A cleaning cloth for glass, which is comprised in such a way, can keep on wiping as it is straightened without being curled since the friction between the glass surfaces is smoothed due to the air in the sponge  50  which is pouring out through the second microfiber cloth  30  by the pressing force when wiping therewith. 
     Although the present invention is described with reference to the preferred exemplary embodiment, it will be apparent to the person of ordinary skill in the art that various changes and alterations of the present invention can be made within the scope of the present invention without departing from the spirit and the scope thereof written in the claims described herein below.
