Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention provides an external appearance which can surely and beautifully pipe a mouth-wear tape to a flocked shoe of various designs and has no "laughing" phenomenon in the mouth-wear portion. The present invention relates to a method of manufacturing a flocked shoe capable of manufacturing an excellent flocked shoe.

[Conventional technology]

2. Description of the Related Art Conventionally, flocked shoes in which a mouth portion is formed in various designs in order to enhance a design effect have been manufactured.
As a conventional method of manufacturing the flocking shoes, the following two methods are mainly used.

The first method is to first set a sock-like backing made of knitted fabric or the like in a shoe mold and apply an adhesive to the outer surface of the backing,
Next, an unvulcanized rubber sheet which is cut into a predetermined shape and is a flocked covering material is adhered to the back cloth to form an upper part. As the planted unvulcanized rubber sheet, a single unvulcanized rubber sheet may be used to form the entire shell, and an unvulcanized rubber sheet planted at the counter portion or the like for the purpose of reinforcement or the like may be used. There is a case to stick. The cover material consisting of the unvulcanized rubber sheet thus planted is attached to the upper part which is attached to the outer surface of the backing cloth to form a shoe-shaped body, and then vulcanized by a conventional method, and thereafter This is a method of removing the shoe from the shoe mold and finally piping the mouth tape to the edge of the mouth part.

The second method is to first set a sock-like backing made of a knitted fabric or the like in a shoe mold and apply an adhesive to the outer surface of the backing,
Next, an unvulcanized rubber sheet which has been cut into a predetermined shape and is not planted is adhered on the back cloth to form an upper part.
The unvulcanized rubber sheet without the flocking is formed by a single unvulcanized rubber sheet to form the entire shell, or by a non-vulcanized non-vulcanized material such as a reinforcing or filling material for a counter portion. In some cases, a vulcanized rubber sheet is used. In this way, a shell material made of an unvulcanized rubber sheet that has not been planted is attached to the upper part attached to the outer surface of the backing cloth to form a shoe-shaped body, and then vulcanized by an ordinary method. This is a method of removing the shoe from the shoe mold later, electrically flocking the flux over the entire upper part, and finally piping the mouth tape to the edge of the mouth part.

In the first method, since the unvulcanized rubber sheet forming the upper portion is an unvulcanized rubber sheet in which hair is planted on the entire surface, the shell material forming the upper portion forms one uncured rubber sheet forming the entire shell. In the case of a vulcanized rubber sheet, at the bonding portion between the sealing sheet and the unvulcanized rubber sheet that seal the butted portion of the rear unvulcanized rubber sheet from the outer surface, the shell material constituting the upper portion is also provided. In the case of an unvulcanized rubber sheet material forming the front shell and an unvulcanized rubber sheet material forming the counter portion, etc., at the bonding portion between these unvulcanized rubber sheets, in both cases, In the bonding portion between the material and the sole, there is a floc implanted in the unvulcanized rubber sheet at the bonding portion, so that good bonding strength cannot be obtained, and water flows from the portion into the shoe. Lack of easy penetration And, there has been a drawback that the adhesive material is extruded reduce the appearance of the shoe from these adhesive portion.

On the other hand, in the second method, since the flocks are electro-flocked after forming the shoe-shaped body, there is no disadvantage as in the above-mentioned first method. Since the step of piping the mouthpiece tape was performed after forming and vulcanizing a shoe-shaped body with the shoe sole attached, the vulcanized and hardened state of the upper part of the upper part of the mouthpiece is Even if you try to pipe the mouth tape, the vulcanized mouth part of the upper part is difficult to deform, so it is difficult to pipe the mouth tape along the mouth part, so the mouth part is formed in a complicated shape to enhance the design effect In this case, there is a drawback that the mouthpiece tape cannot be piped into a shape along the mouthpiece part. Also, wrinkles come close to the front notch with a small radius of curvature in the mouth portion and the portion where the mouth tape on the back overlaps,
When the shoe is viewed from a plane, there is a drawback that a relatively straight side portion extends to the left and right, and a phenomenon called "laughing" occurs in which the mouth portion is distorted.

[Problems to be solved by the invention]

The present invention provides an easy-to-use slip-on tape regardless of whether the slip-on portion is formed in various shapes or is not a flocked shoe in order to solve the above-mentioned drawbacks of the prior art and enhance the design effect. It is an object of the present invention to provide a method for producing flocking shoes, which can produce pig pigs with excellent appearance by being able to perform pig pigging in a reliable manner.

[Means for solving the problem]

The inventor of the present invention has conducted various studies to solve this problem. As a result, when the mouth portion tape is piped, the upper portion is formed of an unvulcanized rubber sheet having no flocking and a knitted fabric having relatively low elasticity. If the part is unvulcanized and easily deformed, pay attention to the fact that even if the shape of the mouth part is complicated, the mouth tape can be piped along the shape of the mouth part reliably and neatly. A backing sheet made of a glued knitted fabric and an unvulcanized unvulcanized rubber sheet adhered to the surface of the backing sheet are laminated and cut into a predetermined shape. Piping the tape on the edge of the to form an upper part, hanging this upper part on the midsole material placed on the shoe mold, pasting it, and plugging the seam at the rear end of the upper part Go After concealed with a sheet or a sealing rubber sheet and a counter material, the shoe sole is attached to form a shoe-shaped body, and then vulcanized by a conventional method and removed from the shoe mold. After applying a primer and an adhesive to the upper part by applying a mask to the upper part, the flux was electrically implanted, and finally it was determined that the masked tape of the mouthpiece tape part and the sole of the shoe should be removed, and the present invention was completed. is there.

Hereinafter, a method for manufacturing a flocked shoe according to the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view showing an example of a flocked shoe manufactured by the method of the present invention, FIG. 2 is a cross-sectional explanatory view showing the structure of an upper sheet before flocking used in the method of the present invention, and FIG. The figure shows the order of manufacturing the upper part before flocking (a)
Is the upper part sheet cut in a predetermined shape,
(B) is a plan explanatory view of a state in which the rear end portion in FIG. (A) is sewn, and (C) is a plan explanatory view of a state in which a mouthwear tape is piped to the mouthpiece in FIG.

In order to manufacture the flocking shoe 1 according to the method of the present invention, first, as shown in FIG. 2, a backing cloth 5a made of a knitted woven fabric having a paste 5c on the surface and a flocking attached to the surface. An unpervulcanized rubber sheet 5b is laminated and the upper part sheet 5 cut into a predetermined shape is prepared. As the backing cloth 5a in the upper part sheet 5, a knitted fabric having some elasticity such as a knit, a tricot, and a bore is preferably used. The unvulcanized rubber sheet 5b includes natural rubber,
An unvulcanized rubber sheet such as synthetic rubber or a mixture of these rubber materials is preferably used, and the method of laminating the backing cloth 5a and the unvulcanized rubber sheet 5b is the same as the composition constituting the unvulcanized rubber sheet 5b. The unvulcanized rubber sheet 5b may be calender coated after the co-glue of the liquid composition having the composition is coated 5c on the surface of the backing cloth 5a.

Thus, the rear end of the upper sheet 5 cut into a predetermined shape as shown in FIG. 3 (a) is opened at the mouth 6 and the bottom as shown in FIG. Sewing to the state. Next, the covering tape 7 which is biased to the mouth 6 is piped along the edge 6a of the covering 6 to produce the upper part 2 before the flocking.

The shoe-shaped body is formed by pasting the midsole 3 and the sole to the upper part 2 manufactured in this manner. As a method of pasting the midsole 3 and the sole 4 to the upper part 2, Then, the middle sole material 3 is placed on a shoe mold and is attached to the middle sole material 3 while the upper part 2 is hung, and then the seam at the rear end of the upper part 2 is tape-shaped without being planted. Sealing rubber sheet 8 or tape-shaped sealing rubber sheet 8
In addition, the shoe is concealed by a half-moon type counter covering material 9 that is not planted with hair, and the shoe sole 4 is attached while being placed on a shoe mold to form a shoe-shaped body.

In order to vulcanize the unvulcanized rubber of the shoe-shaped body thus formed, the material is vulcanized by heating at about 130 to 140 ° C. as usual, and the strength of the material is secured. And remove it from the shoe mold. Subsequently, the portion of the mouthwear tape 7 and the sole 4 are masked with a tape such as an adhesive tape, and a primer such as an organic chlorine-based material and an adhesive such as a urethane resin-based material are applied to the surface of the shoe-shaped body. A flocks made of nylon or the like having a length of mm are electro-flocked, and finally the masking tape is removed to manufacture a flocked shoe 1 as shown in FIG.

(Operation)

As shown in FIG. 2, the method of manufacturing a flocked shoe according to the present invention comprises a backing cloth 5a made of a knitted woven fabric having a paste 5c on the surface and a non-flocked unprocessed cloth stuck on the surface. Since the upper sheet 5 laminated with the vulcanized rubber sheet 5b and cut into a predetermined shape is sewn at the rear end, and the mouthpiece tape 7 is piped along the edge 6a of the mouthpiece 6 to form the upper part 2. Since the mouthpiece tape 7 is piped in a soft state before the strength of the material of the upper part sheet 5 is secured, the mouthpiece tape 7 conforms to the shape of the mouthpiece part 6.
Is easy to sew. Then, after attaching the insole 3 to the upper part 2, the stitched portion at the rear end of the upper part 2 is concealed by the sealing rubber sheet 8 or the sealing rubber sheet 8 and the counter material 9, and the shoe sole is removed. The inner sole material 3, the sealing rubber sheet 8 or the sealing rubber sheet 8 and the counter material 9, and the shoe sole 4 to be attached to the upper part 2 do not have a floc at the bonding part. Therefore, the adhesive strength is high and there is no fear of water intrusion.

Further, since the shoe-shaped body is heated and vulcanized in a state where the mouth tape 7 is piped, the mouth tape 6 is simply sewn to the mouth part 6 as a final product after vulcanization as in the related art. Not just being piped,
Since the piping is performed in a state in which the upper part sheet 5 and the mouth-wearing tape 7 are in close contact with each other, the joined state becomes very good.

After the mouth tape 7 is piped to the mouth part 6 of the upper part sheet 5 in this manner, the part of the mouth tape 7 and the sole 4 are masked with a tape such as an adhesive tape. After applying a known primer such as a primer and a known adhesive such as a urethane-based material, the flocks are electrically implanted, and finally the masking tape between the covering tape 7 and the sole 4 is removed. It is possible to manufacture shoes in which only the necessary parts of the part 2 are planted, and the appearance is very good.

〔The invention's effect〕

As described above in detail, according to the method of manufacturing a flocked shoe according to the present invention, the upper part sheet forming the covering part is made of a footwear tape in a soft state before the strength of the material is secured by vulcanization. Since piping is performed, the mouth tape can be easily sewn to the mouth part of the upper part, thereby improving work efficiency.
Furthermore, even if the shape of the mouthpiece is complicated, it is possible to reliably and easily pipe the mouthpiece tape to a fine portion. And since the mouthpiece tape can be piped in close contact with the mouthpiece part of the upper part, it is difficult for wrinkles to occur at the front notch having a small radius of curvature in the mouthpiece and at the portion where the mouthpiece tape overlaps with the rear part, and further piping the mouthpiece tape. Since the shoe-shaped body is vulcanized in this state, the shoe tape and the upper part are heated at the same time, so that "laughter" generated at the mouth part is corrected, and a shoe with excellent appearance can be manufactured. Furthermore, after vulcanization, a step of masking the tape and the sole of the shoe with a tape, applying a primer and an adhesive to the upper part, electrically flocking the flocks, and finally removing the masking tape between the tape and the sole of the shoe. Since the abutment part and the abutment tape part and the abutment part and the sole of the shoe are securely bonded to each other, the hair is implanted only in the necessary parts of the apper part, so that water is injected into the shoe. There is no danger of intrusion, and even if the adhesive for attaching the sole of the shoe slightly protrudes from the abutment between the upper part and the sole of the shoe, the protruded adhesive will hide the protruding adhesive, Good flocking shoes can be manufactured. Thus, the present invention having various advantages is of great industrial value.
