  However, the conventional arm cover described above has the following problems.

  First, as with an arm cover, the entire knitted fabric is knitted into a flexible cylindrical shape, and a cut edge portion (cut edge portion) is provided at a predetermined portion as described in the cited document 4. In the case of the kind, since the fraying occurs in the state where the hole edge, that is, the cut portion is left as it is, and the fabric structure itself cannot be used, the cut edge is usually twisted with a thread so that the fraying does not occur. ing. The same is true for a general button hole in clothing for performing such a twist. Therefore, when the cut edge portion is provided, a complicated process of turning is essential, which causes a complicated manufacturing process and increases manufacturing cost and productivity.

  Secondly, the raised portion is unavoidably raised in the ridged portion, and the flexibility of the portion is lost. Therefore, in the case of an arm cover used to prevent sunburn when wearing short sleeves, the groin is in direct contact with the skin, so the comfort is greatly impaired due to the sense of incongruity. For those who want to avoid skin irritation such as atopic dermatitis, this is a problem that cannot be ignored.

  Third, this type of arm cover is often used to prevent sunburn when a woman drives a car, and the appearance design is also an important factor. Therefore, if the arm cover is provided with a bevel at the both ends opening and the edge of the hole, and further provided with a stretchable part such as a rubber band at the both ends opening, It becomes an appearance form and is not necessarily preferable in terms of appearance. For this reason, there was room for further improvement from the viewpoint of further improving the appearance (formability) and the merchantability.

  An object of the present invention is to provide an arm cover manufacturing method and an arm cover that solve the problems existing in the background art.

  In order to solve the above-described problem, the method for manufacturing a knitted fabric according to the present invention includes at least cut edge portions 2p, 2q including opening edge portions 2p, 2q at the end portions and hole edge portions 2h for allowing the fingers Hr to pass therethrough. , 2h...

In addition, after the rubber material 3 is cured, the cut edges 2p, 2q, 2h, ... are cut.

  Further, the arm cover Ka according to the present invention has at least a cut edge portion including the opening edge portions 2p and 2q at the end portion and the hole edge portion 2h for passing the finger Hr in order to solve the above-described problem. An arm cover formed in at least a flexible cylindrical shape, and a predetermined range of parts Xp, Xq, Xh ... including the periphery of the cut edges 2p, 2q, 2h ..., silicon rubber material 3s ..., urethane rubber material, natural It is characterized in that coating layers 4p, 4q, 4h, etc. are provided by rubber material 3 using one of the rubber materials.

  On the other hand, according to a preferred aspect of the present invention, sewing portions 11p and 11q for preventing the hole edge 2h from spreading may be provided on both ends of the hole edge 2h.

  According to the arm cover manufacturing method and the arm cover Ka according to the present invention, the following remarkable effects can be obtained.

  (1) Before cutting the cut edges 2p, 2q, 2h..., The rubber material 3 before curing is applied to a predetermined region Xp, Xq, Xh... Including the periphery of the cut edges 2p, 2q, 2h. Is applied, and after the rubber material 3 is cured, the cut edges 2p, 2q, 2h, ... are cut, so that the cut edges 2p, 2q, 2h, ... are held by the cured rubber material 3 ( The occurrence of fraying can be effectively avoided without swaying. Thus, the manufacturing process can be simplified and facilitated, and the manufacturing cost can be greatly reduced and the productivity can be improved.

  (2) Since no turning is performed, substantially continuous flatness is ensured and flexibility is also ensured. As a result, even if it is in direct contact with the skin when worn, comfort can be improved without feeling uncomfortable, especially for people who have weak skin and want to avoid skin irritation such as atopic dermatitis. It will be optimal. In addition, the surface shape is refreshed in appearance, and the appearance shape and the merchantability can be dramatically improved.

  (3) As the rubber material 3 ..., one of silicon rubber material 3s, urethane rubber material, and natural rubber material can be used, so that it is possible to use a general-purpose material that can be obtained relatively easily, and easily and at low cost. Can be implemented.

  Next, preferred embodiments according to the present invention will be given and described in detail with reference to the drawings.

  First, a method for manufacturing the arm cover Ka (knitted fabric K) according to this embodiment will be described with reference to FIGS.

  First, the most basic embodiment of the manufacturing method according to the present invention will be described. In FIG. 1, steps S <b> 1 to S <b> 7 show the steps of the most basic embodiment (basic example). First, the raw cover 20 is manufactured (step S1). The base cover 20 is knitted with a cover material including a thread material and a rubber material into a flexible cylindrical shape using a predetermined knitting machine. The entire structure of the element cover 20 is shown in FIG. Note that “flexible” is a concept including expansion and contraction. The raw cover 20 may have the same diameter as a whole in the longitudinal direction, or may have a different diameter so that the distal end side of the part corresponding to the arm Ha of the human body (see FIG. 9) becomes gradually thinner. The base cover 20 itself can be manufactured as a general known knitted fabric, and in particular, the stretchability and the diameter dimension are selected so that a good fit can be obtained when the base cover 20 is attached to the arm Ha. The length of the raw cover 20 is selected so as to be longer than the arm cover Ka finally obtained by a predetermined length. In other words, as will be described later, the positions of the raw cover 20 after cutting are equal to the length of the arm cover Ka in order to cut the positions that enter the predetermined width inward from both ends 20p and 20q of the raw cover 20, respectively. Select to do so.

  When the raw cover 20 is obtained, the raw cover 20 is turned over and then set on a predetermined applicator. Using the applicator, a predetermined position located on both ends of the inner surface (back surface) Ki of the raw cover 20 is obtained. The uncured rubber material 3 is applied to the range parts Xp and Xq (step S2). If the rubber material 3 is applied to the inner surface Ki in this manner, the rubber material 3 (coating layers 4p, 4q, 4h, which will be described later) directly contacts the skin, but there is no sense of incongruity and comfort can be ensured. It is possible to ensure a good appearance shape while enjoying the effect.

  As shown in FIG. 2 (b), positions Xp and Xq in a predetermined range are selected as positions where the rubber material 3 is applied as shown in FIG. 2B. Specifically, it is applied in a ring shape so as to have a constant width along the entire circumference. FIG. 2B shows an example in which the raw cover 20 is set on a cylindrical jig 51 and applied using an application roller 52 as an example of the application method. As the coating method, other various coating methods such as a coating method by printing can be used. Furthermore, the thickness of the layer may be adjusted by applying a plurality of times of recoating as necessary, not only once. In particular, when the rubber material 3 is applied, the rubber material 3 penetrates into the fabric, and therefore it is desirable to adjust the thickness and type of the fabric. For example, when the thickness of the fabric is taken into consideration, the coating thickness is 0.01 [Mm] (thin dough) to 5 [mm] (thick dough) can be adjusted.

  In addition, as an example rubber material 3, a silicon rubber material 3s is used. In this case, the color of the silicon rubber material 3s is not limited, and various colors that match the color of the base cover 20 can be selected. In particular, a material having translucency is desirable. Thereby, since the presence of the rubber material 3 can be made inconspicuous, there is an advantage that unnecessary discomfort can be suppressed and the merchantability can be further enhanced. The silicon rubber material 3s is used as an example, but a urethane rubber material or a natural rubber material may also be used. Thus, if one of the silicon rubber material 3s, the urethane rubber material, and the natural rubber material is used for the rubber material 3, a general-purpose material that can be obtained relatively easily can be used. is there.

  When the application of the rubber material 3 is completed, the rubber material 3 is stored in a dryer, and the applied rubber material 3 is dried after the set drying temperature and drying time (step S3). When the drying is finished, the positions corresponding to the opening edges 2p and 2q located at both ends of the arm cover Ka in the raw cover 20 are cut by a predetermined cutting machine (step S4). FIG.2 (c) has shown the example cut with the round cutter 55 as a cutting machine. A line L indicates a cutting line. In this case, since the position having the dried and solidified rubber material 3 is cut, the cut can be easily and neatly performed without fraying the cut end. Thereby, the opening edge parts 2p and 2q obtained by cutting become the cut edge parts 2p and 2q of the arm cover Ka.

  Next, a predetermined position on the inner surface (back surface) Ki of the element cover 20, that is, a region Xh in a predetermined range including the periphery of the hole edge 2h where the thumb Hr enters when the arm cover Ka is attached to the arm Ha, is shown in FIG. As shown in (d), the rubber material 3 is applied (step S5). In this case, the shape of the portion Xh in the predetermined range is a strip shape. As the rubber material 3 shown as an example, the same silicon rubber material 3s as the rubber material 3 applied to both ends described above was used. Moreover, as a coating method, various coating methods, such as the coating method by printing, can be used. Furthermore, not only a single coating but also a plurality of repeated coatings may be performed as necessary. When the application of the rubber material 3 is completed, the rubber material 3 is accommodated in a dryer, and the applied rubber material 3 is dried through a set drying temperature and drying time (step S6). Then, when the drying is completed, as shown in FIG. 2 (e), a predetermined length of incision is provided in a predetermined region Xh using a cutter (step S7). Thereby, the cut end of predetermined length, ie, the hole edge part 2h, is formed. This hole edge 2h becomes the cut edge 2h. The target arm cover Ka can be obtained through the above steps and can be manufactured very easily.

  In addition, the above manufacturing method (basic example) is an example, and various changes are possible. For example, when the rubber material 3... Is applied to the raw cover 20, for easy understanding, the step Xp, Xq is applied to the both ends of the raw cover 20, and the portion Xh corresponding to the hole edge 2h is applied. Although the steps have been described as separate steps, they may be performed simultaneously. Therefore, in this case, a single drying step is sufficient. In addition, various embodiments can be implemented. Hereinafter, a manufacturing method according to another embodiment will be described with reference to FIG. Steps S1 to S4, S10 to S13 in FIG. 1 show a first change example, steps S1 to S4 and S20 to S24 in FIG. 1 show a second change example, and steps S1 to S1 in FIG. S4, S30 to S33 show a third modification.

  First, the first modified example has basically the same steps as the basic example (steps S1 to S7), but additional rubber is added after the basic example (steps S1 to S7) is completed. A re-coating step for material 3 was added (step S13). By providing such a re-coating step, the cut edges 2p, 2q, 2h of the cut edges 2p, 2q, 2h are applied again to the cut edges 2p, 2q, 2h of the rubber material 3 applied first. Can be protected. Thereby, there exists an advantage which can prevent generation | occurrence | production of fraying more. In the first modification, steps S1 to S4 are the same as the basic example, and steps S10 to S12 correspond to steps S5 to S7 as they are.

  Also, the second modified example has basically the same steps as the basic example (steps S1 to S7), but after the completion of the basic example (steps S1 to S7), it is shown in FIG. Thus, the sewing parts 11p and 11q for preventing the hole edge 2h from spreading are provided on both ends of the hole edge 2h (step S23). In the case of illustration, the sewing parts 11p and 11q sewed the thread in a direction perpendicular to the cutting direction of the hole edge part 2h. Furthermore, in the second modified example, an additional re-application step of the rubber material 3 is added in the same manner as in the first modified example in order to stably fix the sewing portions 11p and 11q (step S24). Thus, if the sewing parts 11p and 11q for preventing the hole edge 2h from spreading are provided on both end sides of the hole edge 2h, useless expansion of the hole edge 2h can be effectively prevented. There is an advantage that it is possible to contribute to ensuring the durability and maintaining the quality of the entire arm cover Ka, including the hole edge 2h. In the second modification, steps S1 to S4 are the same as the basic example, and steps S20 to S22 correspond to steps S5 to S7 as they are.

  Further, in the third modified example, steps S1 to S4 in the basic example are common, but after the completion of steps S1 to S4 in the basic example, before the hole edge portion 2h is formed, the predetermined position is set in advance. The sewing parts 11p and 11q performed in the second modified example are provided (step S30). And after providing these sewing parts 11p and 11q, the rubber material 3 was apply | coated to the site | part Xh of the predetermined range corresponding to the said hole edge part 2h (step S31). In addition, the applied rubber material 3 is dried, and when the drying is finished, the portion Xh is cut to form the hole edge 2h (steps S32 and S33). Therefore, the third modified example has the same steps S1 to S4 as the basic example. The third modification is advantageous over the second modification in that the re-application of the rubber material 3 can be omitted.

  Next, an arm cover Ka (knitted fabric K) according to the present embodiment and a method for using the arm cover Ka will be described with reference to FIGS.

  The arm cover Ka shown in FIGS. 4 to 8 can be obtained by the above-described manufacturing method, particularly the manufacturing method according to the basic example. As shown in FIGS. 4 to 7, the arm cover Ka is at both ends of the base cover 20 as a main body, that is, both ends on the inner surface Ki of the arm cover Ka, and has opening edges (cut edges) 2p, 2q. The coating layers 4p, 4q using the rubber material 3 ... (silicon moss material 3s ...) are provided in a predetermined range of parts Xp, Xq including the periphery of the hole, and the periphery of the hole edge (cut edge) 2h is included. A coating layer 4h using a rubber material 3 (silicon moss material 3s) is provided in a predetermined region Xh. That is, three coating layers 4p, 4q, and 4h are provided.

  In this case, since the three coating layers 4p, 4q, and 4h are provided on the inner surface Ki of the arm cover Ka (element cover 20), the arm cover Ka is externally covered as described above as shown in FIG. 20 appearance is almost the same. That is, since no turning is performed, substantially continuous flatness is ensured and flexibility is also secured. As a result, even if it is in direct contact with the skin when worn, comfort can be improved without feeling uncomfortable, especially for people who have weak skin and want to avoid skin irritation such as atopic dermatitis. It will be optimal. In addition, the surface shape is refreshed in appearance, and the appearance shape and the merchantability can be dramatically improved.

  On the other hand, when using the arm cover Ka, as shown in FIG. 9, the arm cover Ka can be attached to the arm Ha of the human body. In this case, the arm cover Ka can be expanded and contracted as shown by imaginary lines 20s in FIG. 8, so that it can be expanded and attached to the arm Ha as it is. At this time, the arm Ha is inserted from one opening edge 2q of the arm cover Ka so that the side on which the hole edge 2h is provided becomes the tip, and the thumb Hr is taken out through the hole edge 2h. What is necessary is just to take out the finger He from the other end edge part 2p. FIG. 9 shows a state where the arm cover Ka is attached to the arm Ha. In this case, since the coating layers 4p, 4q, and 4h are provided on the inner surface Ki, the arm cover Ka exhibits an anti-slip effect without providing a conventional rubber band or the like.

  Therefore, according to such an arm cover Ka (and a manufacturing method thereof) according to the present embodiment, before cutting the cut edges 2p, 2q, 2h, the periphery of the cut edges 2p, 2q, 2h is included. Since the rubber material 3... Before curing is applied to the portions Xp, Xq, and Xh within a predetermined range, and the rubber material 3 is cured, the cut edges 2p, 2q, and 2h are cut. 2p, 2q, and 2h are held (fixed) by the cured rubber material 3..., And fraying can be effectively avoided without turning. Thus, the manufacturing process can be simplified and facilitated, and the manufacturing cost can be greatly reduced and the productivity can be improved.

  In particular, it is applied to at least the arm cover Ka formed in a flexible cylindrical shape, and is used for passing the opening edge portions 2p, 2q and / or the finger Hr at the end as the cut edge portions 2p, 2q, 2h in the arm cover Ka. Since the hole edge portion 2h is applied, optimum performance can be obtained from the viewpoint of enhancing the comfort and appearance of the arm cover Ka.

  On the other hand, FIG. 10 shows knitted fabrics K ... according to the reference example. Basically, the manufacturing method according to the present embodiment (the present invention) is similarly applied as long as it is a knitted fabric K having a cut edge similar to the cut edges 2p, 2q, 2h in the arm cover Ka described above. it can.

  FIG. 10A shows an example of a general button hole 31h. Since the button holes 31h have the same structure as the hole edge 2h described above, it is possible to provide a coating layer 32h similar to the coating layer 4h provided in the portion Xh shown in FIGS. . In addition, B ... shows the button fastened to button hole 31h ....

  Moreover, FIG.10 (b) shows the knitted articles K ... which have the same form as arm cover Ka. In addition, H shown with a virtual line has shown the human body. Kb indicates a body winding that is worn from the abdomen to the waist and covers the abdomen and the waist, and 41u and 41d indicate coating layers provided on the upper and lower sides, respectively. On the other hand, Kc represents a supporter attached to the crotch, and 42u and 42d represent coating layers provided on the upper and lower sides, respectively. Kd indicates a glove, and 43s indicates an applied layer.

  The preferred embodiment (modified example) has been described in detail above. However, the present invention is not limited to such an embodiment, and the present invention is not limited to the detailed configuration, shape, material, quantity, numerical value, and the like. Changes, additions and deletions can be made arbitrarily without departing from the scope. For example, it is desirable to apply the rubber material 3 to the inner surface Ki of the knitted fabric K, but this does not exclude the case where the rubber material 3 is applied to the outer surface. Further, the cut edges (2p, 2q, 2h,...) Are concepts including various parts obtained by cutting a knitted fabric, including the illustrated opening edges and hole edges. On the other hand, various modes can be applied to the sewing of the thread in the sewing portions 11p and 11q.
