Description

  The present invention relates to a belt having an external appearance made of natural leather and freely expanding and contracting according to a change in posture when used in clothing.

  Various materials have been used for the belts used for clothing, and they meet a variety of design and dyeing requirements.

  For example, as a belt used by businessmen for clothes (especially trousers), a leather belt is widely used from the viewpoint of business manners. In the field of sports, there are competitions (for example, baseball, golf, etc.) that use leather belts for clothing. Examples of these belts are shown in FIG. 4 as a cross-sectional view.

  As shown in FIG. 4, the conventional belt includes a surface material 1 exposed to the outside when worn, a backing material 2 positioned on the body side when worn, and a core material 3, and ends of the surface material 1 and the backing material 2. The core material 3 is included by sewing together with the thread 4. The front material 1 and the back material 2 use natural leather or artificial leather as a material, and the core 3 is also commercialized with a belt using natural leather or artificial leather.

  Since artificial leather, which is a chemical substance, is a material that does not expand and contract, a belt using artificial leather does not have elasticity in the longitudinal direction.

  Natural leather is generally processed into a belt from cowhide 7 cut parallel to the longitudinal direction of the body when viewed from the whole cowhide 6 (so-called round skin) as shown in FIG. . Since the cowhide fibers extend long in the body length direction 9 (hereinafter referred to as the fiber direction), it is possible to easily cut a large number of cowhides 7 by cutting them in line with the fiber direction 9. There are advantages. However, when the cowhide 7 is cut out parallel to the fiber direction 9 and processed into a belt, the fiber of the cowhide 7 extends in the longitudinal direction of the belt, so that the belt does not expand and contract in the longitudinal direction.

Wearing a leather belt like this on your clothing will not cause the belt to expand or contract. The problem of feeling occurs. In addition, the same problem may occur depending on the meal.
Therefore, a stretchable belt used for clothing has been studied.

  For example, Patent Document 1 discloses a belt using cowhide 8 cut perpendicular to the fiber direction 9. In this way, the cowhide 8 cut from the round skin 6 is cut to a length corresponding to the width, so that when it is pulled in the longitudinal direction, a load acts in a direction perpendicular to the fiber. As a result, it becomes easy to stretch. However, in order to cut the cowhide 8 from the round skin 6, a large number of fibers must be cut.

  That is, the technique disclosed in Patent Document 1 leaves room for improvement from the viewpoint of workability when cutting the cowhide 8 from the round skin 6.

Utility Model Registration No. 3188048

  The present invention solves the problems of the prior art, and by giving stretchability to a band-shaped member made of natural leather, it has the appearance of leather except for metal fittings (for example, buckles), and is stretchable. The object is to provide a belt.

The inventor manufactured a belt that can be expanded and contracted by using cowhide cut out parallel to the fiber direction (cowhide 7 in FIG. 5) so that the cowhide can be easily cut out from the round skin. The technology to do was examined. And we focused on the fact that tannin is used (so-called tannin tanning) as a tanning agent for cowhide which is a material for conventional belts. The tannin-tanned cowhide does not have elasticity as used in cocoons and the like, so it cannot be expected to be elastic even when used as a belt for clothing.
On the other hand, the chrome-tanned cowhide is used for gloves and the like, and has good stretchability.

Therefore, we made a belt using chrome-tanned cowhide for the front and back and put it on a trial for several days.
(a) Low water absorption, easy to repel water (for example, sweat, rainwater, etc.) and durable.
(b) Because it is flexible, it can be worn without discomfort.
And so on.

The present invention has been made based on these findings.
That is, the present invention is a belt used for clothing, and has a stretchable core material sandwiched between a surface material exposed to the outside when worn and a back material positioned on the body side when worn, and the surface material and the back material Is a stretchable belt for clothing made of natural leather with chrome-tanned cowhide, with the front material and core material attached with an adhesive, and with the back material and core material attached with an adhesive.

In the elastic belt for clothing of the present invention, the core material has a two-layer structure consisting of the upper layer on the front material side and the lower layer on the back material side, the width W _EXT (mm) of the upper layer and the width W of the lower layer. _INT (mm) satisfies the W _EXT <W _INT, and it is preferable that the thickness T _INT thickness T _EXT (mm) and the lower layer of the upper layer (mm) satisfies the T _EXT = T _INT. Moreover, it is preferable that an upper stage layer and a lower stage layer are affixed with an adhesive material. Nitrile rubber is preferably used as the core material, and an adhesive containing toluene and N-hexane is preferably used. Furthermore, it is preferable to sew the peripheral portions of the front material and the back material with a thread having elasticity (for example, polyester).

  In addition, the scope of the utility model registration request of the present invention describes a method for producing natural leather called natural leather with chrome-tanned cowhide. Since it is impossible or almost impractical to directly identify the natural leather by structure or properties, the claim for utility model registration is described as natural leather with cowhide chrome-tanned.

  According to the present invention, by giving stretchability to a band-shaped member made of natural leather, it is possible to obtain a belt that has the appearance of leather other than metal fittings and can be stretched, and has a remarkable industrial effect. Play.
