When it comes to whether leather goods are durable, we will think that maintaining leather goods will prolong its service life. But in fact, this is only for finished leather goods, and at the beginning of leather goods production, the direction of cutting the fibers of the leather determines the service life of the leather goods. So why does it involve the fiber direction of this leather material, and how to judge this direction? Today, the editor of Xin Nuo De Leather Goods will take a look with you.

Through the previous content, we know that before the leather goods are made, the leather needs to be cut. The cutting accuracy of the leather parts will directly affect the success of the leather goods production. So we need to use a well-made paper mold to trace on the leather and then cut it. When rotoscoping, because it is done on leather, it must be very careful. If the rotoscoping operation fails, the leather of this part will be damaged and basically cannot be used again.

In addition, when cutting the leather material, it is necessary to consider the directionality of the leather fiber, as well as the bending direction and extension direction of each paper-shaped part. If you don’t confirm in advance, you can cut leather parts on the leather at will to make finished leather goods, which will have adverse effects on practicality and durability in practice. Therefore, generally experienced old cobblers will reasonably arrange the parts that need to be cut on the suitable leather parts before making them, and then cut them. Let me share with you how the old cobbler identified the fiber direction of the leather.

First of all, let’s understand why it is necessary to reasonably distribute the paper molds to various parts of the leather. Since the leather originally belonged to a part of the animal, it has certain growth characteristics. According to the fiber direction of the leather material, it can be divided into more ductile and less ductile parts. At the same time, according to the design of leather goods, the functions of parts during use are different, and the extensibility of leather materials is also different.

If you don’t “use talent wisely” and rationally consider the distribution and cutting of leather materials according to the characteristics of leather materials, the finished leather goods are very likely to have serious problems such as bending parts that are not easy to bend or easy to deform. In addition, the leather has the characteristics of fine fibrous tissue on the upper side (back) and rough fibrous tissue on the lower side (belly). If you make good use of these points, you can easily identify the part of the retail leather and buy the leather needed for production. All in all, only by using the characteristics of leather materials flexibly, the final leather goods will be strong, beautiful and durable.

How to identify the direction of leather fibers? First of all, you must learn to distinguish whether the leather is above or below.

Take cowhide as an example, if the incision of the general leather material is obviously rough, it can be judged that it belongs to the “back” position, and it is considered to be the upper side (back) leather material.

For the same piece of leather, compare the meat surface. If the fibrous tissue is obviously thinner through naked eye observation, it can be judged to be the upper (back) skin, and vice versa, the opposite leather is the lower (abdominal) skin.

In addition, we can also know the fiber direction of the leather by confirming the bending direction of the leather. Generally, the bending direction of the leather is the direction of extension, and the direction perpendicular to it is less extensible.

Vegetable tanned leather often judges the direction of the fiber by the way it is bent.

Bend the leather with light pressure. The direction in which the leather cannot be bent is completely different from the direction in which it can be bent, so we can tell the difference immediately based on this. When performing rotoscoping, you must first grasp this direction, and then decide where to take the parts.

In addition, gently pull the leather material to confirm the extension direction of the leather material. However, the disadvantage of this method is that the thinner leather may be stretched or deformed after being pulled, so it is necessary to control the strength and not use excessive force.
