How do thermochromic and photochromic yarns work?

Thermochromic yarn changes color at customizable temperatures (commonly 30°C, 40°C, 50°C). Photochromic yarn changes color reversibly under sunlight or UV light, returning to original color in darkness.

What applications use color-changing yarn?

Used in anti-counterfeiting labels, creative apparel, brand identification, packaging, smart textiles, and interactive design. Ideal for products requiring visual engagement or security features.

What customization is available?

Custom color-changing thresholds, base colors, color pairs, and application formats available. Temperature ranges can be specified from 20°C to 60°C. UV sensitivity levels adjustable.

Is the color-changing effect reversible and durable?

Yes, both thermochromic and photochromic effects are fully reversible. Under normal use conditions, the color-changing performance lasts 1-2 years. Wash durability: 50+ washes for standard formulations.

What is the minimum order quantity?

Standard MOQ: 500g per batch. Custom development requires minimum quantities based on formulation complexity. Sample orders available for testing and evaluation.
