BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surface treatment method for applying a surface treatment such as painting or flocking to an outer skin of a waterproof or cold boot or other shoes, and a structure for disposing a mask member for surface treatment. And the adhesive is prevented from adhering to portions that do not require surface processing.

[0002]

2. Description of the Related Art FIG. 2 is a cross-sectional view showing an example of a conventional waterproof and cold boot. The waterproof and cold boots 10 are
Is composed of a foot portion 12 (outer skin main body) below the vicinity of the ankle and a tubular portion 14 (covered tubular portion) thereabove. Foot 12 is P
It is made into a footprint by a slash manufacturing method or the like using VC (PVC) or the like. A heel core 16 is attached to the heel portion of the inside of the foot portion 12, a midsole 18 is laid on the heel core 16, and a bag-like backing cloth 20 is attached to the entire inner wall surface of the foot portion 12.

[0003] The upper portion of the backing cloth 20 is extended upward from the opening of the foot portion 12, the upper end thereof is folded inward, and the sewing machine is overlapped with the upper end of the tubular portion 14 which is also folded inward. Is sewn over the entire circumference (22: suture). The tube portion 14 is formed of a different material from the foot portion 12 in a tubular shape. The lower end of the cylindrical portion 14 is sewn (24: suture) over the entire circumference with the upper end of the foot portion 12 by a sewing machine.

FIG. 3 shows another example of a conventional waterproof and cold boot. This is because the waterproof / cold winter boot 10 of FIG. 2 has the upper part of the outer skin 13 and the backing cloth 20 joined to each other at the top of the mouthpiece 26, whereas the waterproof / cold winter boot 28 of FIG. The back cloth 20 is joined to the outside of the lower portion of the mouth portion 26.

[0005] In these waterproof and cold boots, the outer skin 13 may be subjected to surface treatment such as painting or electrostatic flocking for the purpose of decoration or the like. In that case, conventionally, painting or flocking is applied to the outside of the foot portion 12 and the cylindrical portion 14 in advance at the stage of individual components before assembling into shoes, and then the heel core 16,
A method of suspending the insole 18, the backing cloth 20, etc., further sewing the upper part of the backing cloth 20 and the upper part of the cylinder part 14 with a sewing machine, and sewing the lower part of the cylinder part 14 and the upper part of the foot part 12 with a sewing machine. Was common.

[0006]

According to the conventional surface processing method, the cylindrical portion 14 and the foot portion 12 are individually painted,
Since hair transplantation is performed, even if the same surface processing is performed on the surface of the cylindrical portion 14 and the surface of the foot portion 12, both portions 1
2 and 14, the finishing state is slightly different, and the two portions 12 and 14 may be visually distinguished to give an unnatural finish. Further, since the seam 24 of the foot portion 12 and the tubular portion 14 is exposed to the outside as it is, the appearance is bad, and water may enter there.

[0007] As a method of solving these inconveniences, the foot portion 12, the tube portion 14 and the backing cloth 20 are joined in advance, assembled into a shoe shape, and then continuously painted or planted over the foot portion 12 and the tube portion 14. However, in this method, there is a problem that a paint or an adhesive for flocking adheres to the backing cloth 20 and stains are generated. In particular, as shown in FIG. 3, in order to express a sense of different materials with the backing cloth 20, the upper part of the outer skin 13 and the backing cloth 20 are joined at the outside of the lower part of the mouthpiece 26, and a part of the backing cloth 20 is formed. Is exposed to the outside as a collar portion 42, or when a separate member is attached to the mouthpiece portion 26 as a collar material and the portion is not painted or planted, the backing cloth 20 or the collar material exposed to the outside is used. The paint and adhesive adhered to the surface, and stains were noticeable.

Accordingly, the present inventor has proposed a method for preventing paints and adhesives from adhering to portions not subjected to painting or flocking.
As shown in FIGS. 4 and 5, the adhesive tape 30 is used as a mask material and attached to the backing cloth 20 near the mouthpiece 26, and a paint or an adhesive 32 is sprayed or applied to the outer skin 13 in this state. An attempt was made to prevent paint or adhesive from adhering to the backing cloth 20. However, since the backing cloth 20 is generally made of a brushed material, the sealing property is not sufficiently obtained, and the backing cloth 20 is adhered with air by spraying. In some cases, the tape 30 was peeled off, or the paint or adhesive sometimes oozed out of the backing cloth 20 through the gaps between the raised parts, and it was not possible to completely prevent the backing cloth 20 from being stained. In particular, in the following cases, masking by sticking the adhesive tape 30 was not suitable. 1) The backing cloth 20 is a cloth, and the raw cloth having many irregularities is difficult to adhere to the tape. 2) The backing cloth 20 is brushed, and especially the fur is long. The tape is hard to stick and the raising is protruded from the tape. The color of the paint or flocking applied to 13 and the backing cloth 20
4) Even if the joint between the outer skin 13 and the backing cloth 20 is at the upper end of the mouthpiece 26 (shown in FIG. 2), the brushing of the backing cloth 20 is
6 and above ... Paint and adhesive are applied to the raised brush from the mouthpiece 26. 5) The joint between the outer skin 13 and the backing cloth 20 is exposed on the surface so that the backing cloth 20 is elongated upward to show the backing as a collar of a different material (FIG. 4). . 6) A collar member made of a different material is separately attached above the upper end portion of the cylindrical portion 14 and a surface treatment such as painting or flocking is not performed on the collar member: paint or an adhesive is applied to the collar member.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and has been made in consideration of the above circumstances, and provides a surface processing method for shoes in which only a portion required for surface processing can be reliably subjected to surface processing to prevent other portions from being stained.

Another embodiment An embodiment in which the present invention is applied to a waterproof and cold-proof boot having the structure shown in FIG. 3 will be described. The same parts as those in FIG. 3 are denoted by the same reference numerals. FIG. 7 shows a state before surface processing. In the waterproof / warm boot 40, the upper portion of the outer skin 13 and the backing fabric 20 are joined to each other on the outer side below the mouth portion 26, and the upper portion of the backing fabric 20 is folded back to be exposed to the outside to be seen as the collar portion 42. It is like that.
Other configurations are the same as those of the embodiment of FIG. The mask member 36 is sandwiched between portions of the cylindrical portion 14 and the back cloth 20 that are folded inside and overlapped with each other, and are sewn (22: suture) over the entire circumference by a sewing machine. The portion 36a exposed to the outside of the mask member 36 covers and covers the collar portion 42 formed of the backing cloth 20 from the outside.

In the structure shown in FIG. 7, when the outer skin 13 is to be painted, the paint 32 is sprayed or applied to the entire outer skin 13 from the outside. In the case of flocking, the adhesive 32 is sprayed or applied to the entire outer skin 13 from the outside, and then a pile material is adhered by electrostatic flocking to flocking. in this case,
The portion 36a exposed to the outside of the mask member 36 is
Masking the paint and the adhesive 32 by projecting upward from the junction between the collar and the collar 42 prevents the paint and the adhesive from adhering to and dirtying the collar 42.

After the coating and flocking of the outer skin are completed, the mask member 36 is strongly pulled upward, and the mask member 36
It can be torn off from the perforations by the suturing system 22 and removed. As a result, as shown in FIG. 8, the waterproof and cold-proof boots 40 in which the outer skin is coated or planted 38 (planted in the example of FIG. 8) are completed. In this case, the remaining portion 36b of the mask member 36 that has not been removed is embedded between the tubular portion 14 and the backing cloth 20, so that it cannot be seen from the outside and does not impair the appearance. . Further, since the remaining mask member 36b is thin and flexible, it does not adversely affect comfort.

According to the two embodiments described above, the following effects can be obtained. 1) The coating and the flocking 38 can be applied neatly to the boundary between the backing cloth 20 and the collar 42, and the finish and appearance are beautiful. 2) The back cloth 20 and the collar 42 are not stained at all. 3) Since the back cloth 20 and the collar 42 are not stained at all, there is no need to select the back cloth 20 according to the color of the paint or the flocking 38, and the back cloth material can be freely selected. 4) The mask member 36 is superimposed on the tubular portion 14 and the backing cloth 20 and sewn together with a sewing machine, and after coating and flocking, the portion 36a exposed to the outside of the mask member 36 is cut off from the perforation. Good, high processing efficiency. 5) Since the painting and the flocking 38 are applied in a state where the foot portion 12 and the tubular portion 14 are stitched, a completely identical series of painting and the flocking 38 can be applied to the foot portion 12 and the tubular portion 14. 6) Since the painting and the flocking 38 are applied in a state where the foot portion 12 and the tube portion 14 are sewn, the seam of the painting and the flocking 38 does not appear at the boundary between the foot portion 12 and the tube portion 14. 7) Since the painting and the flocking 38 are performed in a state where the foot portion 12 and the tubular portion 14 are sewn, the seam formed by the sewing threads 22 and 24 is sealed with the paint or the adhesive 32, so that the waterproof property is improved. 8) Even when the back cloth 20 is folded over to form the collar 42 (FIG. 7) or when the collar is attached to the upper part of the mouthpiece 26 with another member, no stain is generated on the collar.

In the above embodiment, the outer skin 13 and the backing cloth 2 were used.
Although the 0 and the mask member 36 are joined by sewing with a sewing machine, they can be joined with an adhesive instead of sewing. In this case, the portion 36a exposed to the outside of the mask member 36 after the painting and the flocking is completed is cut off with a cutter knife or the like and removed. Alternatively, if a perforation is previously formed as a cut line in the mask member 36, the exposed portion 36
a can be torn off by hand.

In the above embodiment, the outer skin 13 and the backing cloth 2 are used.
Although the painting and the flocking are performed in a state where the mask member 36 is joined to the 0, the painting and the flocking can also be performed in a state where the mask member 36 is sandwiched between the outer skin 13 and the back cloth 20 and the sewing is not performed. In this case, the mask member 36 is pulled out after the painting or the flocking, and the outer skin 13 and the backing cloth 20 are joined. Further, if the mask member 36 is made of a double-sided adhesive tape, the mask member 36 can be firmly held between the outer skin 14 and the backing cloth 20.

In the above-described embodiment, the mask member 36 is removed after the flocking has been completed. However, it is also possible to remove the mask member 36 after applying the adhesive and then carry out electrostatic flocking. In this case, the application of the adhesive is "surface processing"
Corresponds to. Further, in the above-described embodiment, the surface processing is performed only on one side partitioned by the mask material 36. However, different surface processing may be performed on both sides. Further, in the above-described embodiment, the case where painting or flocking is performed as the surface processing has been described. However, the present invention can be applied to other surface processing. Further, the present invention can be applied to shoes other than waterproof and winter boots.
