It has the 2nd finger part 12b, the 3rd finger part 12c, the 4th finger part 12d, and the 5th finger part 12e. The first finger portion 12a to the fifth finger portion 12e are formed in a cylindrical shape in which each fingertip side is closed. The wrist portion 14 is knitted by inserting elastic yarn (rubber yarn) and has an opening through which a wearer can insert his / her hand. The glove 10 is knitted in the order of the fingertip portion 12, the main body portion 11 and the wrist portion 14 using a flat knitting machine.

  The glove 10 having the above-described configuration is suitable for touch screen operation of a portable terminal that is an object of the present invention, and a fiber used for knitting a glove in order to provide a glove that realizes an unprecedented function and ease of use. The yarn and its arrangement have the following characteristics.

(Structure of front yarn)
The surface yarn made of ultrafine fibers used in the present invention can be obtained, for example, by dissolving or decomposing and removing sea components of sea-island type composite fibers made of two different synthetic polymers, or two different synthetic materials. It can be obtained by separating and separating each component of a split type composite fiber made of a polymer. Here, examples of the synthetic polymer used for producing the surface yarn composed of the ultrafine fibers used in the present invention include polyester, polyamide, polyvinyl alcohol, polyolefin and the like, and polyester is particularly preferable. . In addition, the thickness of the surface yarn composed of the ultrafine fibers used in the present invention is preferably ultrafine fibers obtained by processing polyester called so-called “microfiber” into a fineness of 8 micrometers or less. . Although it depends on the thickness of the yarn, the greater the number of filaments, the better the water absorption, adsorptivity and permeation resistance, the softness of the fabric and the less irritation to the skin.

Specific examples of ultrafine fibers are as follows.
・ Ultrafine fiber (a): Split yarn composed of 167 dtex / 1777F polyester filament yarn after splitting (can be dyed after splitting)
・ Ultra-fine fiber (b): Split yarn made of polyester filament yarn of 39 dtex / 8360F after splitting ・ Ultra-fine fiber (c): Split yarn made of polyester filament yarn of 167 dtex / 528F after splitting What is the above split yarn? This means a thread in which nylon is inserted between polyesters, and the number of filaments is increased by melting the nylon part by splitting (post-processing). “Dtex (decitex)” is a unit of the thickness of the yarn, and represents the mass of a 10,000 m yarn in grams. For example, “167 dtex” of the ultrafine fiber (a) means 167 g at 10,000 m. “F” means a filament, and “1776F” of the ultrafine fiber (a) means that a yarn is composed of 1776 filaments. A multifilament composed of a large number of ultrafine fibers forms innumerable gaps inside, and when the dirty surface is wiped, the wiped oil film and dirt move to the gaps inside the multifilament. Can be wiped off repeatedly.

(Configuration of the back thread)
As the back yarn made of the heat-retaining fibers used in the present invention, various heat-retaining materials that are thin, light and warm can be adopted. (1) Far-infrared heat storage materials (fibers kneaded with far-infrared radiation ceramics) The material that absorbs the energy radiated by the human body and at the same time the material in the fiber that is associated with the far-infrared radiation is radiated and has excellent heat retention), (2) The heat-retaining material (if the fiber absorbs moisture, the water molecules and the fiber Materials that generate heat by the affinity between them), (3) radiant heat reflective heat insulating materials (materials in which aluminum or titanium is applied to the fibers so as not to let the heat radiation radiated from the body escape), etc. .

Specific examples of the heat retaining fiber are as follows.
・ Heat-retaining fiber (a): High-performance fiber that warms and keeps the fiber warm by increasing the absorption and radiation of far-infrared rays by kneading fine ceramics uniformly into the fiber ・ Heat-retaining fiber (b): Heat generated by adsorption heat High-performance fiber that keeps the body warm by heating itself, heat-retaining fiber (c): High-performance fiber that exhibits far-infrared effect by kneading fine-grain coffee charcoal into the fiber

(Arrangement of front and back threads)
In order to provide a glove that is suitable for touch screen operation of a portable terminal, which is an object of the present invention, and realizes an unprecedented function and ease of use, as shown in FIG. In order to arrange the yarn 1 on the knitted fabric surface side and arrange the back yarn 2 made of heat retaining fibers on the back side of the knitted fabric, plating knitting, which is a method of knitting the front and back while drawing two yarns simultaneously adopt. As a result, a knitted fabric having a composite function can be knitted using yarns having different functions such as the front yarn 1 made of ultrafine fibers and the back yarn 2 made of heat retaining fibers.

  The glove 10 according to the present invention can be knitted using one or more surface yarns made of ultrafine fibers. When the front yarn is one (see FIG. 3), it is mainly suitable for indoor work. Conventionally, a clerk at a mobile shop or a watch glasses shop wears a glove produced by cutting and sewing cotton knit fabric when handling a product. According to the glove 10 according to the present invention, the surface of the knitted fabric is used. The thin glove suitable for handling products can be provided because the wiping performance and gripping power on the side are well demonstrated. In addition, when the number of front yarns is two (see FIG. 4) or three, it is mainly suitable for outdoor use. According to the glove 10 according to the present invention, the wiping performance and the grip force on the surface side of the knitted fabric (as shown in the test results described later) are well exhibited and the friction force is approximately twice as large as that of the conventional glove. Moreover, since the heat retention on the back side of the knitted fabric is also excellent, it is possible to provide an easy-to-use thick glove suitable for touch screen operation of a portable terminal outdoors. In this way, gloves suitable for applications from thin to thick can be provided.

  The glove 10 according to the present invention has a surface yarn made of ultrafine fibers dyed in an arbitrary color after splitting, and can be knitted using two or more surface yarns of different colors made of ultrafine fibers. In this case, for the ultrafine fiber, the ultrafine fiber (a) that can be dyed after the above-described split fiber is used. This makes it possible to create a design that is different from conventional gloves using ultrafine fibers consisting of a single color.

  The tip portions 13a, 13b, and 13c of the first finger portion 12a, the second finger portion 12b, and the third finger portion 12c of the glove 10 according to the present invention are made of conductive fibers for touch screen operation of the mobile terminal.
