Recommended Ironing Temperatures

Your iron may be displaying units such as low, medium, and high temperatures. For ease of understanding, the temperature display is in Celsius and Fahrenheit units.

Clothing Type Temperature (Fahrenheit) Temperature (Celsius)
Acrylic 250-275°F 121-135°C
Nylon 250-275°F 121-135°C
Spandex/Lycra 250-275°F 121-135°C
Acetate 250-290°F 121-143°C
Polyester 275-298°F 135-148°C
Wool 275-300°F 135-148°C
Silk 280-300°F 138-150°C
Rayon 325-375°F 163-190°C
Triacetate 325-390°F 163-200°C
Cotton 380-400°F 193-204°C
Linen 400-450°F 204-232°C

What is Considered Low, Medium, and High Temperature?

Here’s a correlation between the low, medium, and high temperatures to approximate degrees of temperature.

1. Low Temperature:

This setting is usually 230 degrees F or lower. You can set the dial to 1. You can iron fabrics such as acetate, lycra, nylon, etc.

2. Medium Temperature:

Temperature ranges from 230 degrees F to 300 degrees F. Set the dial to 2 or 3. This setting is appropriate for ironing acrylic, lace, polyester, silk, and wool.

3. High Temperature:

This setting sets the temperature at 300 degrees or more. Setting the dial to 4 or above (if available) sets the highest temperature. This temperature is perfect for cotton, denim, linen, rayon/viscose
