Method for obtaining a modified collagen absorbent product from leather

A method to obtain a modified collagen absorbent product from leather, characterized in that the method comprises the steps of:

• a. aerating flat leather pieces each having a molecular structure, for a period of 15-45 days;
• and
• b. then collecting said flat leather pieces with an initial value of relative humidity equal to or less than 35%;
• and
• c. then carrying out a classification of the flat leather pieces by a size, said classification of flat leather pieces accomplished by means of mechanical shaking;
• and
• d. then obtaining the flat leather pieces with a maximum final length between 0.75-1.5 mm;
• and
• e. then putting the flat leather pieces in a drying oven, said drying oven being constructed of stainless steel and or galvanized steel, wherein said drying oven has a longitudinal configuration to have the flat leather pieces longitudinally arranged along the drying oven, the drying oven including fins to remove and progress the flat leather pieces along said drying oven, said drying oven detecting a temperature so that said drying oven can regulate the temperature of the leather pieces within a range;
• and
• f. then applying heat in the drying oven so that the flat leather pieces are subjected to a hot air flow, the drying oven including a particle filter to collect particles generated by the application of heat to said flat leather pieces;
• and
• g. regulating the temperature applied during the period of time so that the relative humidity in the flat leather pieces is reduced to a value between 0.5-5%;
• and
• h. reducing the temperature of the flat leather pieces to a room temperature;
• and
• i. obtaining a hydrophobic and oleophilic absorbent product of collagen modified from leather.
