The first experimental study of sisal fiber preparation and testing of fiber, soft
fiber, sisal sun to dry, then cut into short strips. Boil a solution of HCl concentration, 5, 10, 15 and 20%, temperature 100 ° C for 5 minutes, rinse thoroughly with water. Then dried in hot air oven at a temperature of 80 degrees Celsius observe and record the color of dry fiber. Then test the softness of the fibers Sisal fibers, packed into a tube. Measure the height of the fiber to the same level. Steel ball dropped into the tube to press the fibers to collapse. Measuring the collapse of the fiber using Vernier recording experiment repeated three times for an average.
