How to choose materials for notepad customization?
Custom-made notepads generally choose materials such as PVC, PU, imitation leather, leather, color-changing leather imported from Italy, and medium and high-quality leather. For custom-made notepads, how to choose appropriate materials to make notepads is very important. So how can we choose the most suitable material?
First we have to learn to identify materials. When identifying, the material should be checked first to determine the type of face leather. For example, if the "leather" grain layer is unmodified, the face leather with the original natural characteristics: the pores of cowhide are small, irregular and uniform; the pores of goat skin are "tile" in rows; the three holes of pigskin are piled up , in the distribution of characters.
Yellow cowhide has fine tissue fibers, buffalo cowhide is rough, and pores and eyes are large. If the grain layer is modified and loses its original characteristics, it should be carefully classified and identified according to the processing technology. The aniline leather coated with aniline is characterized by a crystal bright surface, which is very bright, not dazzling, and has no plastic feel. Natural leather is matured into leather, the cowhide is generally 5-6mm thick, the surface layer is a grain layer, the tissue fibers are fine and compact, smooth and beautiful, with good strength and wear resistance; the inner layer is a suede layer, with thick fibers and large gaps. The surface is fluffy. The first layer leather is smoother and flatter than the second layer leather, and the second layer leather is slightly rough. The surface of the two-layer leather can not be seen rough after coating, film transfer or film, but the film transfer leather has poor low temperature resistance and is prone to wrinkling when the temperature is low. The cowhide two-layer leather is flat and has no obvious defects after embossing, while the pigskin two-layer leather often has three piles of pores and eyes, where the luster is dark. When distinguishing shaving leather and front leather, it should be noted that shaving leather is a pattern that destroys the original grain layer and then presses it. On the surface of the skin, the pores of the front leather are there, which can be identified by careful observation.
Artificial leather is coated with a layer of organic material on the cloth base, which is divided into two types: thin (imitation sheep leather) and thick (coated with foamed organic material, and then embossed with patterns). Synthetic leather is made by pressing organic fibers and then adding a finishing embossing. Recycled leather is to grind the leather residue and leather fiber, bond it with adhesive under high pressure to form a sheet, and then slice it to the required thickness by a leather machine, and then finish it to make it have certain leather characteristics, and it is widely used in luggage. Leather goods, a small amount used to make shoes. When distinguishing real leather from artificial materials, look at the appearance first. Leather does not have a base, and artificial materials have a base. When you touch it with your hand, the artificial material has a very strong plastic feel and a bright luster. In winter, it feels cool to the touch, and the leather is smooth and does not feel cold to the touch. Press the softer part of the finished product with the thumb, there will be many small and uniform patterns in the leather around the thumb. When the thumb is lifted, the pattern disappears; while the artificial material may have no pattern, or there may be thick lines, and the pattern does not disappear when the thumb is lifted. , indicating that the grain layer on the surface of the material and the underlying mesh layer have been separated. To identify real leather or artificial leather, you can also observe the cross section. The cross section of the real leather is composed of irregular fibers. After scraping the broken skin fibers with your fingernails, there is no obvious change in the cross section. For the real leather, different parts + irregular texture, the nose smells fishy odor. Artificial leather smells of plastic or rubber, and the texture of each part is consistent. Foiled leather is a synthetic leather with an artificial surface layer attached to the loose fleshy fiber layer of the lower layer of natural leather, which cannot be called "leather", but is based on the inner layer of natural leather.
To sum up, it can be seen from the following aspects: A. Look. First look at the appearance, the real leather has no base, and the artificial material has a base; the real leather has small pores, and the imitation leather does not. b. touch. When you touch it with your hand, the artificial material has a very strong plastic feel and a bright luster. In winter, it feels cool to the touch, and the leather is smooth and does not feel cold to the touch. c. smell. Genuine leather smells of animal fat (i.e. leather odor), while imitation leather smells of plastic. D. pressure. Press the soft part of the finished product with the thumb, there will be many small and uniform patterns in the leather around the thumb. When the thumb is lifted, the pattern disappears, that is, the leather; while the artificial material may have no pattern, or there may be thick lines. The pattern does not disappear, indicating that the grain layer on the surface of the material and the underlying mesh layer have been separated. E. Check. Observing the cross section, the cross section of the dermis is composed of irregular fibers. After scraping the broken skin fibers with fingernails, the cross section has no obvious change. For the dermis, the texture of different parts is irregular, and the nose smells fishy, while the artificial leather smells plastic or rubber. Taste, the texture rules of each part are consistent. Foil leather is a synthetic leather with an artificial surface layer attached to the loose fleshy fiber layer of the lower layer of natural leather, which cannot be called "leather", but is based on the inner layer of natural leather. F. water. Put tiny water droplets on the surface of the skin. After a few minutes, the water droplets spread through the pores, and you can see obvious wet spots and absorb water. g. burn. The edges and corners of the burnt leather have a burning smell of hair, and the imitation leather has a plastic smell. h. color. Genuine leather is dark and soft, while imitation leather is bright.
