Fengmi brings you into the workshop, understand deeper about the world's top level of the leather processings and leather products.It needs to use Leather Measuring Machines, leather drums , leather ironing machines, leather embossing machines, leather shaving machines, leather splitting machines, leather fleshing machines, vacuum dryer and many other kinds of machines.

1.Infiltration: leather soaked in the drum, to regain the water lost in original salinization .

9. Retanning: determine the final look of leather, feel, texture, thick, grain feeling. (no photo)

10. Dyeing: using organic dyes, aniline evenly on the whole thickness.

11.The filling: lubrication layer, better elasticity, softness and pulling (no picture)

12.Drying: eliminate the humidity: the cortex flat out on the heating plate.

17. Trim: abandon parts cannot be used. 

18. Meticulously sorting :decide leather ability of friction resistance, resistance to rub off and stain resistance. For high-grade leather, need to apply a thin layer of transparent lacquer , you will need to daub on SC to make uniform color pigment and a transparent protection layer. The Soul without going through the steps.
