What is the glow duration of this product?

Velve glow-in-the-dark products use rare-earth phosphorescent technology. They charge in normal light for just 1–3 minutes; natural sunlight gives the brightest, longest glow. The glow is brightest in the first 10 minutes, then gradually fades; in complete darkness it remains visible for 4–6 hours. Available in 120 colors with green, blue, and yellow glow options. Charging longer does not extend glow time.

What applications is this product suitable for?

Suitable for embroidery thread, sewing thread, raised embroidery thread, and specialty applications. Available in high-brightness and metallic finish options. Custom colors and specifications available.

Is this product non-toxic and safe?

Yes. Velve's glow products use non-toxic strontium aluminate phosphorescent pigment. No radioactive materials are used. Products are safe for textile applications.

What is the difference between Method 1 and Method 2 glow yarn?

Method 1 uses phosphorescent masterbatch filament blended into the polymer before extrusion for uniform glow. Method 2 uses plied phosphorescent filament twisted with a base yarn for a stranded, stripe-like glow effect.

What are the packaging and MOQ options?

Available in cone winding, hank, paper tube, and branded label packaging. Standard MOQ: 500g per batch. Custom packaging with private labeling and logo printing available.
