1. Name of the raw material for frosted leather maintenance: imported mist spray gun (1.0 caliber), air pump, hard cleaning cloth, copper wire brush, 600 water sand, seven kinds of leather color replenishing agent, leather reducing agent, leather back cover color fixing agent.

2. Frosted leather post-treatment: The frosted leather post-treatment process requires high requirements for operators and must strictly follow the leather maintenance process, otherwise it may cause errors that cannot be saved.

3. Post-treatment process of matte leather: grinding of matte leather, modeling of portrait cameras, color replenishment and grease, and background cover fixing.

a. Frosted leather grinding: The grinding operation requirements of the frosted leather are higher than that of suede. When using a cleaning cloth or a copper wire brush, you must use careful and light force to avoid partial fading of the surface of the leather fluff and causing difficulties in color repair. Especially for some worn leather surfaces, sand can be used to whisk the polished leather surface. In addition, some blackened leather surfaces can be polished to eliminate dark spots.

b. Portrait camera shaping: The leather jacket will deform after dry cleaning or washing, mainly on the shoulders and the hem of the clothes. If the shoulder pad falls off, you can remove the leather jacket and sew the shoulder pad with needle and thread. The leather jacket can be glued to remove the glue from the leather jacket. When the portrait camera is fixed, you can use a brush to organize along the fluff.

c. Color replenishment and fattening: The leather jacket will fade slightly after dry cleaning, while the leather jacket is relatively good to wash and fade. Just add color and fat to the leather jacket appropriately to restore the original color and feel. The key to complement the color of leather jackets is to choose the standard color. A similar color supplement color can be matched according to the color. When matching the color, you can compare the color on white paper. Only by applying the matching color on the paper and blowing it dry can you really see whether the color is correct. If the color is already very close, you can conduct the final test and comparison in the place where the leather jacket is not obvious, and then make appropriate adjustments. The dye after matching the color is set aside. In addition, according to the feel of the leather jacket, add an appropriate amount of leather reducing agent to the prepared dye, stir evenly and filter with a filter, and then use an imported mist spray gun to make even colors, and dry thoroughly after completion.

Note: Do not add too much leather reducing agent, otherwise it will cause the surface of the leather to darken.

d. Back cover fixing color: Check whether the color of the leather suede is uniform after the color is supplemented. If the color on the surface of the leather is darker, you can then gently polish it with a cleaning cloth to make the surface of the leather lighter. If the fluff is tied together, use a white cleaning cloth to gently loosen it, then use a leather cover, dilute it with distilled water, then spray it evenly on the leather surface with a spray gun, and finally place it in the dryer at 50 degrees for 30 minutes or on the portrait machine for 20 minutes to fix the color.
