Pressure and steam emission
Pressure is important to determine the quality of the steam into the boiler (more dry, less dry). The higher the pressure the better the quality because the water particles, being smaller, do not wet the garment too much. A pressure 4 to 5 bars is ideal for steam to efficiently penetrate into the fibers and to stretch them. During ironing a drier steam is better to finish the process correctly, and achieve optimal results.
