Upper surface modification process

Name: First, full-grain cow leather: benzene dyeing, semi-benzene dyeing, lighting
The quality of the leather is high and the color is bright and natural. Fenness recommends the following three methods for modification;
method one:
a. The Victoria Cream DC4000/S1 is applied to the leather surface with a natural sponge, generally colourless, but coloured creams can also be used to enhance the colour effect.
b. After the cream is dry, use a small amount of DC3800 to fill in the hard wax and a medium rotation cotton cloth wheel. The black shoe leather is made of black filler wax DC3819/A.
c. Apply light wax water AR6000 series, or spray with AR6100.
d. Finally polished with a wool wheel and DC7300 polishing wax.
Method Two:
a. First use a small amount of DC3800 filling wax and cotton cloth for grinding and filling at medium speed.
b. Apply DC4000/S1 cream on the leather surface. Hou dry.
c. Gently polish with a cotton cloth and remove excess wax to make it uniform.
d. Finally polished with a wool wheel and DC3700 polishing wax.
Method 3:
a. Apply natural sponge sponge Victoria Cream DC4000/S1 as a top coat.
b. After the wax is dry, it is polished with a DC3800 filling wax and a cotton wheel of medium rotation speed.
c. Apply DC4100 series coated surface with strong silky feeling.
d. Gently polish with a cotton cloth and polish with DC3700 wax.
(If necessary, 30% of DC4100/S1 can be used in DC4100.)
Note: If the leather surface of the whole grain is hot-scalded before the decoration, so that the skin blue and grain surface tighten, the effect is better.
The wax water AR6000 applied in the above methods is the most natural luster. If you need a higher gloss, you can use Super-K or AR7000 series, the gloss of these two products, higher than the AR6000, while the former has a strong waxy feel, the latter has a smooth feel, high silky feeling .
In general, Super-K or AR7000 series with good permeability is better, and AR6000 with poorer permeability is better.

Name: Second, full grain leather: pigments and more cover coating
This type of upper itself should have very smooth and consistent gloss characteristics. Painting should also not destroy the natural feel of the leather. Therefore, it is basically the same as the modification process of the first kind of benzene dyed leather, but it must be used with a strong force during grinding.
Third, full-grain leather: classical shadow effect This kind of leather is generally vegetable tanned leather (commonly known as tree cream skin). Classical and shadow effects occur when sanding with a cotton cloth. The method of modification is as follows:
a. Apply DC4000/54 series polish wax.
b. Polish with a small amount of DC3800 wax and cotton cloth to observe the shadow effect.
c. Face coated with DC3400/S1 Victorian wax.
d. Finally polished with DC3700 and wool wheel.
Description: If you want to achieve a higher gloss effect. The DC4000/S1 can be replaced with an AR6000 hand or AR6100 or AR7000 series spray.

Name: Eight, leather (skin) and suede (anti-fur)
During the production of such shoes, due to different working procedures, the leathery feeling of these skins is often “inflated” without the feeling of “anger”, which affects the appearance. The following methods can be used to restore the skin to “angry”:
Method one: If the skin is darker, it is only necessary to use DC 4354/2 renewal agent to spray the above. This is a water-based additive that can restore skin feel, but it will make the original leather darker and make it uniform and consistent. This product also enhances the softness of the skin. The gun pressure is 4atm and the nozzle is 0.5mm or 1mm.
Method two: If the skin itself is light in color, use SE5200 (solvent) into the skin recovery agent. These two kinds of additives are natural “irritations” that will not affect the tone of the skin but also enhance the soft touch and skin. The nozzle pressure is 4atm and the nozzle diameter is 0.5mm or 1mm.
Note: If the leather itself has a color difference and must be saved, then add no more than 5% of the Fenice CX series dye to the SE5200 to make the skin even.


Name: Nine, oily skin and waxy skin
This leather is crafted using heavy oil and heavy wax, and Finnis has three treatments:
method one:
a. spraying with DC4401 water-soluble grease, with 4atm and 0.5-1.0mm nozzle, will enhance the sense of grease and make the color even, soft and silky feel. Gloss is natural and oily.
b. CX dyes can be added for uniform color.
Method Two:
a. Spray with SE5200 using a 4atm and 0.5-1.0mm nozzle and flash dry.
b. Make the skin enhance the feel of oil wax.
c. If necessary, add dyes of Fennis CX or LN to enhance the color effect.
