Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of coating a color image on a leather, and more particularly, to a method of coating a color image on a leather to form a predetermined pattern or image of high resolution on a leather, And to a color image coating method of a leather which can be mass-produced not only in a small quantity of various kinds but also in a high-quality, high value-added image.
Generally, leather such as natural leather or artificial leather is manufactured variously according to processing type and use.
Depending on the production process, leather (natural leather) is subjected to fat removal, dry surface processing and dyeing, and various types of natural leather products are produced depending on the method of dyeing and the content of the additives. Natural leather (Vegetable) is used for various purposes and is made to suit the characteristics through color expression and additives through dyeing.
Aniline Laather and Valonea Leather are used for high quality car seats. Most of them are Nappa leather products. Nappa leather is most widely used. It is the most practical method because it is coated with the leather surface to improve the durability of the raw hides, and the touch is also excellent. Also, it is resistant to contamination and does not penetrate well even with a little bit of water. It is mainly used for processing of cattle, sheep and pig leather and is used in almost all leather products.
Artificial leather is made of woolen fabric with uniformly applied material. Main raw materials are mainly produced by PVC and urethane, and urethane is mainly used. Artificial leather is produced so as to directly produce raw materials themselves or to apply a certain amount of raw materials on a material which can be a nonwoven fabric or base (base material) by means of a roller or a blade to maintain the material thickness. In this process, it is produced by the foaming process depending on the characteristics of the material and its use.
In addition, the color necessary for the raw material is mixed with the material, or the color is expressed through the processing after the production.
These processes include color representation through mixing in production, or color reproduction through post-production processing. Digital printing, silk printing, and gravure film thermal bonding are mainly used, and gravure printing type deformed printing Method is also used.
There are many limitations in expressing the desired shape and color on the surface of the leather. In other words, due to the nature of the material, the natural leather is subjected to a process of painting on natural materials, which is difficult due to the repulsive force of the natural material possessed by the leather, and the work is performed through dyeing. There is a problem that silk screen or digital print is used in some degree and mass production is very difficult.
Artificial leather is very difficult and limited to use because it is deformed when heat is applied due to the characteristic of the material, and there are many restrictions due to elasticity and heat sensitivity even when it is combined with the printing form before and after processing. Therefore, although the color expression method is limited and some printing methods are adopted after the processing, there is a limit to the printing cost and the mass production facility in mass production.
In addition, the gravure printing heat bonding method can not be used for leather products, and artificial leather is also expensive to manufacture an initial copper plate and is not suitable for various design color expressions. In addition, silk printing method is used, but it is difficult to mass-produce because of limitations in continuous production and color representation.
In order to express the image in the existing natural leather and artificial leather, the image is processed through silk printing, UV printing and gravure heat bonding after completion of the production of leather. This is because there is a problem that the production speed and high value-added image representation method have limitations, and the cost of production is very high because of expressing various designs and colors, and there are various problems such as continuity, productivity, product cost and mass production, There is a problem that leather production is difficult.
Accordingly, the present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to provide an image color coating method in a simplified manner so that it is simpler than the conventional processing method, And to provide a color image coating method of a leather which can be implemented.
