How to identify leather uppers

In natural leather, the most common materials used for leather uppers are cattle leather, pig leather, and sheep leather. In the leather of the same type of animal skin, due to the difference in leather making process, the properties of the finished leather are different. Very different, can be divided into: front leather, leather, suede, suede, embossed surface leather, leather repair and other layers. A natural grained upper leather is a front leather. Such as: cattle positive leather, pig positive leather, sheep positive leather. The frontal leather of the cattle has a delicate and shiny leather surface. The pores are small and shallow. They are arranged in a circular shape and feel full and elastic. The leather surface of the front leather of the cattle is similar to that of the cow front leather, but the pores are round and flat, and the holes are not obvious. The surface is more delicate than the front of the cattle. Although the front leather of the horse is similar to Niu Zhengge, its physical properties are very different from that of the cow's frontal leather. There are a few leather shoe manufacturers or sellers who use the horse's frontal leather as the cow's frontal leather to deceive consumers. The pig's frontal leather has a rough leather surface, large pores, and a distinctly triangular arrangement of three groups. The frontal leather of the sheep has a fine leather surface and the pores are arranged like fish scales. The hand feel is soft and full of extensibility. The grain features of all the above frontal leathers are obvious, and there are natural lines appearing after pressing with a finger. The grain-modified upper leather is trimmed leather. Such as: cattle repair leather, pig repair leather. The leather surface of the shaved leather is even, beautiful and soft. The grain surface layer has no original features after modification. No natural lines appear after pressing with your finger. Therefore, the appearance of the shoe is difficult to distinguish. The suede upper leather is suede (including plush suede leather). Such as: cattle suede, pig suede, cashmere leather. Because the leather is napped, the appearance of the shoes is difficult to distinguish. If it is suede leather. Can be distinguished by the back. The embossed upper leather is embossed leather. Such as: cow embossed leather, pig embossed leather. Because the surface leather embossed, so the appearance of the shoe is also difficult to distinguish.

Cut off the epidermis The modified upper leather is split leather. Such as: cattle second-level repair leather, pig second-level leather repair. Although this surface leather is natural leather, its intrinsic performance is far less than that of frontal leather, and there is no natural pattern after pressing with a finger.

In natural leather, if it is impossible to distinguish the type of animal leather, it can be distinguished by observing the leather, the cut surface of the leather, or even the fiber under the microscope. Of course, this is more difficult for consumers to achieve.
