Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cloth tape for fastening a string, which is fastened when wearing sports shoes, to the sports shoes.

[0002]

2. Description of the Related Art In recent years, cloth tape has been used to further reduce the weight of sports shoes. This cloth tape is used as shown in FIG. 1 as a fastener for fastening a string to be tightened when wearing sports shoes to the sports shoes. The fastener is formed in a substantially inverted V-shape by folding back the cloth tape at a predetermined position, and sewing the cloth tape to the surface of the sports shoe with the both ends separated. Such fasteners are formed in two rows of several places at the center of the upper surface of the sports shoe and are symmetrical, and the straps are passed through each of the two rows of fasteners alternately. Are attached to the sports shoes in a zigzag fashion.

[0003]

The cloth tape is generally fixed to the shoe, unlike the replaceable string, so that the portion that comes into frictional contact with the string gradually becomes fuzzy as the sports shoe is used, Finally, when a sudden force is applied, such as when dashing, it will break at that part. Therefore, recently, it has been an issue to extend the life until the fracture as much as possible.

[0004] The present invention has been made in view of such circumstances, and an object of the present invention is to provide a cloth tape for sports shoes, which can further extend the life until breakage.

[0005]

According to one aspect of the present invention, there is provided a cloth tape for fastening a string to be fastened to a sports shoe when the shoe is worn. The cloth tape is coated with a wear resistance improving resin. The cloth tape referred to here refers to a fiber cloth tape including a woven cloth and a string formed by a braid method, warp knitting, weft knitting, or the like. The wear resistance improving resin may be a silicon-based synthetic resin. This reduces the friction of the cloth tape against the string, prevents fluffing, and makes the cloth tape less likely to break.

According to a third aspect of the present invention, in addition to the first or second aspect, the cloth tape is woven with nylon yarn. This woven structure is preferably a plain weave as described in claim 4. With this configuration, the wear resistance of the cloth tape is further improved. The reason for this is that nylon fibers have particularly high wear resistance as general-purpose fibers, and in addition, they have a weaving structure. It depends on the difficulty.

[0007]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing one embodiment of the cloth tape of the present invention together with sports shoes sewn with the cloth tape.

[0008] The cloth tape 1 of the present embodiment is used as a fastener 11 for fastening the string 3 to be tightened when the sports shoes 2 are worn on the sports shoes 2. in this case,
The sports shoes 2 may be sports shoes used for any sport performed by wearing shoes, such as shoes for jogging, shoes for sprinting, and shoes for basketball.

The cloth tape 1 is usually plain woven with nylon yarn or polyester yarn and has a width of about 7 mm and a thickness of about 0.1 mm.
In the present invention, the material and the weaving method of the yarn, or the dimensions of the cloth tape are as follows.
There is no particular limitation. For example, the weaving method may be a plain weave, a twill weave, a satin weave, a double binding weave (bag-to-bag weave), a braid, a circular knit, or a warp knit. However, as described above, nylon yarn is preferable because it is superior in wear resistance to polyester yarn. The nylon yarn may be a spun yarn or a long fiber multi-yarn.

Incidentally, the cord 3 is, for example, about 7 mm in width and about 1.
5 mm or the like is used. Here, the wooly ester yarn means a yarn obtained by giving a crimpability to a polyester yarn by false twisting or the like. However, in the practice of the present invention, the material, knitting method, dimensions, and the like of the cord 3 in FIG. 1 are not particularly limited.

The fastener 11 turns the cloth tape 1 upside down at a predetermined position and folds the cloth tape 1 slightly obliquely so that the end of the folded cloth tape does not overlap the end of the original cloth tape. After being changed, the both ends of the cloth tape 1 are sewn to the surface of the sports shoes 2, respectively, thereby forming a substantially inverted V-shape. By forming the fastener 11 in this manner, the cloth tape 1 is sewn to the sports shoe 2 without difficulty, and when the string 3 is passed through the fastener 11, the cloth tape 1 3 makes the contact smooth.

The fasteners 11 are formed in two rows of several places at the center of the upper surface of the sports shoe 2 so as to be symmetrical, and the strings 3 are passed through the two rows of the fasteners alternately left and right. Thereby, the string 3 is fixed to the sports shoes 2 in a zigzag manner. In order to form a plurality of fasteners 11 in one row, one cloth tape 1 may be used for each fastener 11, but in this embodiment, one cloth tape 1 is used. Each of the fasteners 11 is formed by folding back zigzag so as to be substantially inverted V-shaped at the place where the fasteners 11 are formed, and sewing around the V-shaped portions to the sports shoes 2 respectively. . still,
The V-shaped portion may have an inverted trapezoidal shape.

The cloth tape 1 of the present embodiment used as described above is coated with a wear resistance improving resin in advance. As the abrasion resistance improving resin, a silicon-based synthetic resin can be used. As the silicon-based synthetic resin, there is, for example, Nikka Silicon AM-500 (trade name of Nikka Chemical Co., Ltd.). By applying the abrasion resistance improving resin to the cloth tape 1, the friction between the cloth tape 1 and the string 3 is reduced, and the abrasion of the cloth tape 1 is prevented. The abrasion resistance improving resin may be made of a material other than a silicon-based synthetic resin, such as a fluororesin. In short, any resin can be used as long as it is durable and has improved wear resistance.

Hereinafter, a method of applying a synthetic resin for improving abrasion resistance will be described with reference to an example of Nikka Silicon AM-500. The adhesion of the Nikka Silicon AM-500 to the cloth tape of the present invention is used in an aqueous solution. This is because uniform adhesion can be achieved by this method. The concentration of this aqueous solution is preferably 20% or more, most preferably 20%.
%. If the concentration is less than 20%, the effect of improving abrasion resistance sharply decreases, and even if it exceeds 20%, this effect does not change so much and the cost increases.

In practice, this Nikka Silicon AM-
500 is used by adding melamine M-3 (trade name of Sumitomo Chemical Co., Ltd.), which is a melamine resin, and Sumitex (trade name of Sumitomo Chemical Co., Ltd.) as a catalyst. If this is indicated by the amount of adhesion to the cloth tape, the silicon compound component is about 7 to 9% owf (the amount of adhesion to the fiber).
Needless to say, the method of attaching the abrasion resistance improving resin may be an appropriate method such as a coating method or a spray method.

FIG. 2 is a longitudinal sectional view showing an example of a step of applying a wear resistance improving resin to the cloth tape 1.
It is prepared in advance in the container 41 at the right end. The cloth tape 1 in the container 41 is connected to a tension bar 4 provided above.
After being uniformly extended in step 2, it is introduced into the dip tank 43. The dip tank 43 contains an abrasion resistance improving resin heated to about 40 ° C.
The abrasion resistance improving resin is applied by bypassing the roller 43a submerged in the dip tank 43.

The cloth tape 1 that has exited the dip tank 43 is guided to an adjacent mangle 44, and is pressed between two rollers 44a to remove extra abrasion resistance improving resin adhered thereto. Thereafter, the cloth tape 1 is introduced into the dryer 45. Inside the dryer 45, a large number of guide rollers 45a are arranged vertically, and hot air heated to 140 to 150 ° C. by a gas burner (not shown) circulates. It is hung alternately between upper and lower rollers and dried by hot air. The cloth tape 1 that has left the dryer 45 is stored in a product container 46 at the left end in FIG.

An abrasion resistance test was performed on the cloth tape 1 of the present embodiment configured as described above. For comparison, an abrasion resistance test was also performed on a conventional cloth tape. The conditions for these wear resistance tests are as follows.

<Conditions of Wear Resistance Test> (1) Regarding the cloth tape of the embodiment . Using a cloth tape 1 having a width of 7 mm and a thickness of 0.7 mm plain-woven with a nylon thread, the cloth tape 1 was subjected to Nikka Silicon AM-500 (trade name) 20 in the process shown in FIG.
%, Melamine M-3 (trade name) 0.7%, and Sumitex (trade name) 0.3%, after being immersed in an aqueous solution in a dip tank 43, extra liquid adhered by a mangle 44 is removed. Squeezed, then put in the dryer 45 and 14
It was dried with hot air at 0 ° C. The attached amount of the silicon component of the cloth tape 1 was about 7 to 9% owf.

(2) Regarding the cloth tape of the comparative example . Two cloth tapes having a width of 7 mm and a thickness of 0.7 mm which were plain-woven with nylon yarn were used.

(3) Test Method vs. Hex Bar Wear Test Method (JIS D4604). That is, as shown in FIG.
The cloth tape 1 is hung on a 5 mm hexagonal rod 51 at an angle of 85 ° and the horizontal end of the cloth tape 1 is vibrated by a vibration drum 52 having a diameter of 400 mm.
5kg with a vertical edge of 2.3kg
3 On the other hand, the vibration drum 52 is connected to a crank 55 by a crank arm 54, and the vibration drum 52 is rotated left and right by rotating the crank 55. With this rotation, the cloth tape 1 comes into frictional contact with the outer periphery of the hexagonal bar 51, and this is repeated.

The results of the wear resistance test are shown in Table 1 below. As is clear from Table 1, the cloth tape 1 of the embodiment has 1
Even after frictional contact up to 0000 times, it did not break, and little fuzz was seen on the friction surface, and almost no change was observed. On the other hand, the two cloth tapes of the comparative example are:
After about 300 times, a little wear appeared, and after about 500 times, all the friction surfaces were worn and a lot of fuzz was generated.
The book broke 1730 times and the other one broke 1200 times. Thus, it was proved that the cloth tape 1 of the example had excellent abrasion resistance as compared with the cloth tape of the comparative example.

Therefore, the cloth tape 1 of the present embodiment exhibits excellent abrasion resistance when used as the fastener 11 of the sports shoes 2, and its breakage is greater than that obtained when a conventional cloth tape is used. It is clear that the lifespan up to can be extended.

[0024]

[Table 1]

[0025]

As described above in detail, according to the first aspect of the present invention, there is provided a cloth tape for fastening a string to be tightened when wearing sports shoes to the sports shoes. Since the abrasion resistance improving resin is applied to the tape, friction of the cloth tape against the string is reduced, fuzzing is prevented, and the life of the cloth tape until breakage can be further extended.

According to the second aspect of the present invention, since the wear resistance improving resin is a silicon-based synthetic resin,
Friction of the cloth tape against the string is significantly reduced, fuzzing is also prevented, and the life of the cloth tape until breakage is greatly extended.

According to the third aspect of the present invention, since the cloth tape is woven with nylon yarn, the nylon fiber itself has high abrasion resistance, and the friction between fibers in the woven structure is small. Accordingly, the cloth tape surely has excellent wear resistance, and as a result, the life of the cloth tape until the cloth tape is broken is prolonged.

According to the fourth aspect of the present invention, since the woven structure is a plain weave, the cloth tape surely has little friction between fibers, and therefore has excellent abrasion resistance. The life before tape breakage is prolonged.
