Description

A method for preparation of leather for mustang and toscana}

The present invention relates to a method for producing a Mustang and Tuscan leather using Buffalo leather and to a leather produced therein. More particularly, the present invention relates to an ironing process and a painting process using a painting roller. The present invention relates to a manufacturing method capable of reducing manufacturing costs of Mustang and Tuscany, while having a pattern almost similar to that of natural leather for Mustang and Tuscany, and a manufactured leather thereof.

Today, leather is most commonly used for cows, sheep, pigs, horses and other mammals.

The most commonly used is cow leather, a cowhide leather of more than two years of age, thick, tough, and rough pores of Steer Hide, cowhide of two years of age or older, cowhide fibres, dense, or large pores. Hyde (Caw Hide) Small and medium-sized leather, 6 months to 2 years old, thick and tough than calfskin, a little rough on the surface, but used as a material for high-quality shoes and calf leather 6 months old, very soft and light. It is classified as Calf Skin because its pores are small and its surface is very fine.

The next most popular lamb leather is expensive, and it is classified as higher than cowhide due to the soft touch of sheepskin. Lamb leather is thin, soft, small pores, soft lamb skin and casual. Primarily used as shoes or gloves, it is classified as Sheep Skin, a light, soft, fibrous structure.

Buffalo hides, which are buffalo leather, have small, natural wrinkles on the front and are soft, but have large furrows and flaws, and are easily stained or stained with water.

In general, the technique of making leather is very difficult and only after several stages of processing, the leather fabric is produced. This process involves first washing the dirt attached to the raw skin and then removing the hairs, and various kinds of weapons for making leather. And penetrate into the raw protein by adding a glass chemical. When combined, the thickness is cut and dyed to suit the purpose. It is only through drying that it becomes a perfect leather.

Representative methods of processing leather are Nappa Type, Drumdyed Type, Nubuck Type.

The Nappa Type is the most common leather product, which is coated on the leather surface, which makes the skin durable and practical and does not penetrate even with slight contamination or moisture, while the skin is not soft and delicate.

Drumdyed Type is called Naked Type in other terms, and it is processed to show the natural state as it is. In humans, it emphasizes the softness of the skin itself. have.

Nubuck Type is similar in appearance to suede, but suede is brushed by the back of the leather and nubuck is brushed by the surface of the leather, so it has no gloss and various effects depending on processing. Its excellent fit makes it difficult to clean because of its contamination, and when worn, brushed powder can be stained and the seams may have color differences.

Toscana is a product made of Tuscan fatty goat leather, and the leather surface with hair is made of leather lining, and the inner surface of the leather is processed to make it warm.Mustang is 6 months to 1 year after birth. It is a general name of the product that cuts the amount of fur into 12-18mm, and it is a kind of cloth that has the characteristics such as leather's uniqueness, luxury, warmth, cold protection, and windproof. Dye it and use it by altar.

In order to make Mustang or Tuscan with natural leather, the first step is to remove dust and dirt from the raw hides, and then beat, process, carding, combing, and brushing the hair and leather to achieve the original texture. Is carried out.

Afterwards, even though the type, age, and harvest season are the same, there are differences in color, so dyeing is done to harmonize the color when making the garment. Be careful not to damage the texture of the leather during this dyeing process. In particular, the dermis dress or emulsion may be damaged by the effect of the dyeing process, there was a disadvantage that requires a high level of dyeing techniques. In addition, these processes were expensive in terms of cost.

The present invention has been invented to solve the above-mentioned difficulty in processing the Tuscan or Mustang and the disadvantages of the buffalo leather surface,

It is intended to provide a method for producing natural leather for Mustang and Tuscan using buffalo leather.

Another object of the present invention is to provide a mustang and Tuscan natural leather produced by such a manufacturing method.

In order to achieve the above object, the present invention is to produce a leather having a pattern almost similar to natural Mustang and Tuscany by the painting process by the painting roller during the processing process of the buffalo leather of the first water processing and dyed fiberized state Characterized in that it comprises a step to.

In addition, after the ironing (Ironing) it is characterized in that it not only adheres the color of Mustang or Tuscany well, but also includes a step of making it glossy.

In general, the basic stage of the processing of leather comprising buffalo leather consists of the following steps:

 1st processing process: The process of straightening the leather, spraying it with proper moisture, putting it in the milling drum, and then rotating it to soften the leather (quenching).

Secondary processing process: Toggling process where the leather is dried in a pin state to make the thickness and deviation constant

Tertiary Machining Process: Surface Grinding Evenly

4th process: process to dye the surface uniformly

5th process: The step of forming the original shirunken pattern using a milling drum (Milling drum).

6th process: Process of spraying waterproof, water repellent, deodorant with spray

In the above-mentioned processing process, it is usually produced by dyeing after the fourth processing to give the required color, and in the case of the nubac type, it is manufactured by the process of producing the color after the ambo processing and polishing.

In order to give the pattern and feel of the Mustang and Tuscan leather using the buffalo leather, which is an object of the present invention, the painting process by the painting roller must be included after completion of the fourth processing step, and then A roing process is added.

The two processes will be described in more detail as follows.

The process of differentiating painting using a painting roller rather than spray or hand to create a natural pattern after constant dyeing of the surface:

This process is a printing-like effect, the pattern occurs naturally to a certain thickness, buffalo leather is thick, uneven thickness is not suitable for printing by printing, buffalo leather has a lot of scratches Because of its characteristics, this painting method not only covers the scratches of the raw skin, but also naturally creates a pattern. When replacing it with a spray, not only does the pattern not appear naturally, but also when the pattern is formed, the thickness of the dye is unevenly sprayed and is not suitable.

In this manufacturing step, the pattern and color are determined, and in this process, the pigments and binders are generally used in water by volume paint 30-40, preferably 40: binder 40-50, preferably 50 (anionic acrylic system). Binder 25-30 + Water-soluble urethane binder 15-20): Mix with water 10-20. In this process, fluorescent pigments may be mixed in the binder, or pearls may be mixed in various colors, and paraffin coating may be used instead of dyes to create a unique atmosphere.

Next, the ironing process (ｉｒｏｎｉｎｇ):

This process adds color and is added after the general coating process, to smooth the surface to increase dye fixation strength, and the most suitable temperature and pressure are 70-90 ° C, preferably 80 ° C and 10-30. Psi, preferably, ironed at a pressure of 20 Psi.

In addition, in order to express the artificial mustang and Tuscany of the present invention, after forming a pattern with a paint roller and applying an aqueous and oil-based coating, it is possible to solve the problem of blemishes, which are disadvantages of buffalo leather, or color not sticking well. Can be.

Through the above process, the buffalo leather combines the original Shirunken pattern generated by passing the artificial pattern generated by the painting roller and the ironed buffalo leather through the milling drum, and is similar to Mustang and Tuscany. It will have an appearance and feel.

The present invention will be described in more detail with reference to the following examples, but the present invention is not limited to these examples.

Using a milling drum (Milling Drum) to run for about 30 minutes to soften, to form a natural pattern (Shirunken).

Example 10

Post Treatment Process

After spraying water repellent, use a feed measuring machine to cut to the appropriate width and length.

As described in detail above, according to the present invention, in the process of forming color and pattern during the processing of buffalo leather, by using a painting roller, without using printing or spraying, the natural nature of the leather for Tuscan or Mustang Has the effect of making a pattern. It is impossible to have a natural pattern of Tuscany and Mustang by the conventional spray method or the method of painting by hand, but this is made possible by using a painting roller. Thereafter, the leather is made of high gloss through an ironing process and then passed through a milling drum, whereby the original natural pattern of leather is formed, thereby producing a leather having a pattern and texture of Tuscany or Mustang.

The process of the present invention is effective in producing low-cost bars, mustangs and tuscan raw hides at a low cost, and the leather produced through such a process can be used in various ways such as sofas and clothes. Mustang and Tuscany can be replaced by the processing of cheap buffalo leather in Korea.
