of Fique Fibers
[0029]Fique fibers with a length of 35 mm were cut using a guillotine. The fibers were subject to an alkaline process at 80° C. for 2 hours, using a solution of 666.6 g of potassium hydroxide and 3333.3 ml of water.
[0030]Subsequently, the fibers were rinsed and the bleaching phase was carried out, in which 2918 ml of water, 80 g of caustic soda at a concentration of 90%, 2.0 g of magnesium sulfate, 200 g of antifoam (stearic alcohol) and 800 g of hydrogen peroxide in a concentration of 10% (w / w) were added.
[0031]The solution obtained was taken to a temperature of 80° C., kept for one hour and then the fibers were rinsed 3 times by overflow. Finally, the fiber was subject to a softening process, for which a solution was prepared with 3920 ml of water and 80 g of a siliconized nanoemulsion. This solution was taken to a temperature of 60° C. in order to add the fiber and run it through the process for one hour. The resulting cottonized fiber was dried in an oven at 40° C...

of Fique Fibers
[0032]Fique fibers with a length of 35 mm were cut using a guillotine. The fibers were subject to an alkaline process at 60° C. for 0.5 hours, using a solution of 222.2 g potassium hydroxide and 3777.7 ml water.
[0033]Subsequently, the fibers were rinsed and the bleaching phase was carried out, in which 2918 ml of water, 80 g of caustic soda at a concentration of 90%, 2.0 g of magnesium sulfate, 200 g of antifoam (stearic alcohol) and 800 g of hydrogen peroxide in a concentration of 10% (w / w) were added.
[0034]The solution obtained was taken to a temperature of 80° C., kept for one hour and then the fibers were rinsed 3 times by overflow.

of Sisal Fibers
[0035]Sisal fibers with a length of 35 mm were cut using a guillotine. The fibers were subject to an alkaline process at 80° C. for 2 hours, for which a solution of 666.6 g of potassium hydroxide and 3333.3 ml of water was used.
[0036]Subsequently, the fibers were rinsed and the bleaching phase was carried out, in which 2918 ml of water, 80 g of caustic soda at a concentration of 90%, 2.0 g of magnesium sulfate, 200 g of antifoam (stearic alcohol) and 800 g of hydrogen peroxide in a concentration of 10% (w / w) were added.
[0037]The solution obtained was taken to a temperature of 80° C., kept for one hour and then the fibers were rinsed 3 times by overflow. Finally, the fiber was subject to a softening process, for which a solution was prepared with 3920 ml of water and 80 g of a siliconized nanoemulsion.
