The oil edge will play a good role in protecting the leather. A good oil edge will bring a smooth feel and have a relatively environmental protection effect. The oil edge process is a very technical work. For the leather edge and leather protection, the number of bags with good quality will be more. Oil edge generally refers to a layer of oily substance with the same color as the above parts painted on the hand-held (shoulder strap) or leather edge of the bag. It is used to cover the incision of leather and the exposed edge after combination, and protect the leather to make the leather more resistant to damage.

The effect of good edge oil is smooth to the touch, with a "softer" color, which is coordinated with the fabric. Poor edge oil feels rougher and darker in color. Many big-name bags use imported glue, which has a low odor and is more environmentally friendly. In addition, it seems to be painted evenly. The quality of the oil edge directly reflects the quality of the bag. Because hand-painting is a very technical process, a bag of good quality needs to be hand-painted at least 3 times. Thick leather, 6 times or more.

Identify the quality of edge oil?

1. Uniform, complete, smooth, elastic, not "on top"

The edge oil is applied to the surface of the leather and is called "upper". A slight and well-proportioned "upper" is normal, but it cannot be uneven. Adsorption of edge oil, gloss, anti-cracking, anti-moth-eaten, and environmental protection are all important. Poor edge oil is not shiny, easy to fall off, and moth-eaten.

2. The quality of handwork

The side oil of the bag is not as thick as possible. The thickness of the side oil is determined by the characteristics of the leather. Some thick leather materials need to be coated with oil many times to cover the edges, and the oil edges are naturally thick. Applying the edge oil thinly and well is one of the criteria to test the quality of the edge oil. If the bag is damaged in terms of edge oil, the main reason is that it has a certain relationship with the materials and processes it uses, and in the production of edge oil, fillers are generally used in the primer, and it will be carried out on the top. The ointment, the effect produced in this way will be relatively smoother, but there is another way to directly apply the ointment on the top, and then continue to polish it. This method is actually a good way to make it. But compared with the former, it will be slightly worse, and in terms of materials, the effects of different materials will be different.

·How to choose edge oil?

Edge oil can be divided according to the following aspects:

Color: various, can be colored

Concentration: thick or thin, can also be adjusted as needed

Gloss: can be divided into matte, medium light, high light

Price: ranging from ten yuan to one or two hundred yuan per kilogram. It is necessary to understand the characteristics of each oil, suitable for different materials, and select the corresponding edge oil according to the quality required by customers.

Type: In terms of types of edge oil, it is mainly divided into two types: water-based edge oil and oily edge oil. Under normal circumstances, the oily edge oil attribute mainly has the attribute of high gloss, and it should not be burnt. The water-based edge oil means that the edge oil properties are matte and can be ironed.
