Qualia Synthetic Fabric Dye, Easy to Use, Perfect for Synthetic Fabrics: Polyester, Spandex, Nylon, and More, Ultra-Concentrated Colors for Vibrant Results, Aubergine Purple, 1 Pack

Dyed my polyester/synthetic fiber jacket with minor, visible streaks. Don't think you can avoid streaks.No better than similar products.

I tried numerous dyes and failed to dye a polyester dress. This dye worked on the Synthetic Nylon Lace part of the dress just not the polyester. I followed the directions and even did it numerous times, looked online and watched youtube videos as to how to succeed, and polyester satin is pretty much impossible to recolor unless you resort to painting it with acrylic paint. I don't recommend this for polyester but I do recommend it for nylon. High heat is needed.

This worked great on dying my Stanley clear lid. I’ve used other brands and they haven’t worked. Easy to use just follow directions.

I guess I expected it to be darker but it was pretty color

Like a dumb dumb i bought a full on white swimsuit (smh) no one wants to see a middle aged overweight women in a wet white swimsuit.... not a great look. Thought of dying it, but was skeptical of how well this would work. But, given the alternative I gave it a shot.1. It works. Like really REALLY well. Reminder, this is synthetic swimsuit material.2. It's super easy to use. Soak, rinse, wash. Done3. The color is EXACTLY as described. The canary yellow is so bright and vibrantSummary: the midwest has been saved from what would have been a visual tragedy on par with the people of walmart sort of experience.Worth every penny. as I'm not rich enough to have put everyone that viewed me in a white swimsuit into therapy for mental distress I definitely was the winner in this scenario.

Was more on the "grey" side of the purple I thought it would be.

Worked well. Stinks.

The color was right, but doesn’t work on synthetic fabrics. Buy Rit instead.
