Yes, you can use iron-on on rayon, but with caution.
Understanding Heat Sensitivity of Rayon
Rayon is a heat-sensitive fabric. According to reference 2, "Fabrics that contain...rayon...are heat sensitive and require a transfer that applies at a lower heat application to reduce scorching or burn marks on the item." This means you can't just use the high heat setting you might use for cotton.
How to Safely Apply Iron-On to Rayon
Here's what you need to keep in mind:
- Lower Heat: Reference 2 says the ideal heat temperature is 280 degrees and below.
- Test First: Before applying your iron-on to your main project, test the heat and application process on a hidden part of the rayon fabric or a scrap of similar material.
- Short Bursts: Instead of pressing the iron on for a long time, use short, repeated bursts of heat. This helps to avoid scorching.
- Use a Pressing Cloth: Placing a thin cotton cloth between the iron and the rayon can provide an extra layer of protection.
- Check the Iron-On Instructions: Your specific iron-on product may have its own instructions, so it's best to follow those guidelines carefully.
Example
Let's say you want to apply a vinyl design to a rayon t-shirt. Here's a breakdown of the process:
- Preheat your iron to a low setting, ideally below 280 degrees.
- Place the t-shirt on a flat, hard surface, like an ironing board.
- Position the vinyl design where you want it on the shirt.
- Cover the design with a pressing cloth.
- Press the iron on the design for 10-15 seconds, using firm but not excessive pressure.
- Remove the pressing cloth and check if the design has adhered properly.
- Repeat the pressing process, focusing on any areas that haven't bonded fully.
Summary
| Consideration | Action |
|---|---|
| Heat Sensitivity | Use low heat (280 degrees or below) |
| Application | Apply in short bursts, don't press for long periods |
| Protection | Use a pressing cloth to prevent scorching |
| Instructions | Follow specific product instructions |
| Testing | Always test on a small, inconspicuous area first |
By following these guidelines you can safely and successfully use iron-on on rayon.
