Soaking is an important process used to remove blood and dirt from the leather, replenish dehydrated water, restore the leather to its raw state, and facilitate subsequent chemical treatment. Dehydration and limewater soaking will cause the lime milk to swell, loosen the leather's collagen fibers, and break down and remove hair, fat, and the epidermis.

After unhairing and liming, the hide is split in half along the spine, a process called splitting. A fleshing machine is then used to remove the flesh and fat adhering to the inner surface of the hide. This process is sometimes performed after lime soaking, and it allows the thickness of the hide to be adjusted.

First, the remaining flesh and fat on the back of the hide are removed again. Then, using a band knife, the hide is separated into two layers: the face layer and the flesh layer, cut to the specified thickness. (Sometimes, the hide is separated into layers after tanning.)

Remove impurities such as hair follicles that could not be removed during the epilation and cutting soaking stages, and clean the surface layer. Use a razor or similar device to remove plaques.

Re-soak in lime milk to use the alkaline property to loosen the leather's collagen fibers.

Residual lime is removed from the leather through unhairing, liming, and re-liming. This neutralizes the limed hides and facilitates the penetration of the tanning agents during the tanning process. The fermentation (oiling) process uses proteases to break down and remove unwanted proteins and create a smoother surface layer.

Next comes the pickling process. The chemicals used in the tanning process must be acidic in order to dissolve, so before the tanning process, the leather is soaked in an acidic solution to make it suitable for absorbing the tanning agent.

The acids in the leather are neutralized with alkali and adjusted to ensure even penetration of the dye and fatliquor.

The leather is then dyed to the desired color using dyes. The basic requirements for dyes are color, solubility, and dyeing properties for leather. Dyeing is the process of coloring the material using dyes that meet these requirements.

Drying is the process of allowing the dye and additives to fully penetrate the leather. Drying can be done naturally, with hot air, or under vacuum. This is a crucial step that directly impacts the leather's feel.

The leather is then moistened to make it easier to knead. A creaser is then used to stretch the leather, giving it flexibility and elasticity. Next, the leather is pinned onto tension boards or secured to mesh to dry flat and remove excess moisture.

The surface of the leather is painted to emphasize the beauty of its color and sheen, and to enhance its durability.

The surface is machine polished or ironed. If necessary, embossing and brushing are also applied.

The transferred cardboard is sorted and managed according to product number and size, and a considerable amount of cardboard is required to make one mold. Based on this, the cutting process begins.

Even when dyeing leather using the same formula, color and sheen can vary depending on the prevailing climate and humidity. Especially with light-colored leathers, such as camel, color can be uneven even within the same piece. When cutting leather, the tailor will match the color and grain, while also imagining the finished product.

After matching the color and texture, each piece of leather is carefully hand-cut by the craftsmen, especially the curved parts, which can better show the craftsmen's skills.

The finished pieces are assembled as shown in the pictures. The jacket's appearance will vary depending on the color and texture of the front and sleeves. Each leather jacket uses approximately 35 pieces of leather.

Skilled craftsmen carefully thin the metal piece piece by piece, especially the curved parts, which are particularly challenging.

This is the final result after the thinning process. If the leather is smooth and has no bumps at the thinned part, the subsequent sewing process will be much easier for the craftsman.

The picture shows the back of the leather. The divided sleeves and side parts will also be neatly glued and processed. Many overseas products skip this step and sew directly, resulting in many products not fitting well.

But Y'2 takes even the invisible parts more seriously.

Creating the “corners” such as the collar point, the curve of the flap, and the cuffs is very difficult.

With over 40 years of experience, we make the incisions and use secret techniques to create beautiful shapes.

When sewing, adjust the tension of the sewing machine to the highest possible level. This is to maintain durability and prevent the thread from unraveling. If the thread floats, it will start to unravel from that part.

Sewing machines are adjusted to certain standards and sewn with care, pride and sincerity.

The pockets are also overlapping and thick, but have been thinned down to create a beautiful finish. The stitching is also beautiful, firmly embedded in the leather.

All buttons are hand-sewn. Strong buckles are installed for durability. Careful and tight wrapping creates enough space so the thick horsehide can withstand repeated opening and closing.

Each garment is made through the collaboration of skilled craftsmen at every stage. Only products that pass Y'2 LEATHER's inspection, such as checking the seams, button and zipper closures, are delivered to customers.
