What triggers the color change?
Photochromic (UV-reactive) threads respond to UV/sunlight. In bright sunlight the stitched areas change color and revert when UV is removed.
Is this a unisex fit?
Yes — all styles use a unisex cut. Choose your usual size for a standard fit;
How do I choose the right size?
Check our size chart (measurements in cm/in). If you fall between sizes, consider intended fit: choose the smaller size for a snug fit, the larger for a relaxed look.
How should I wash pieces with photochromic embroidery?
Follow our special care guidelines to preserve both embroidery and photochromic performance:
Hand wash: cold or ≤30°C water, mild neutral detergent, gently soak and lightly agitate; do not rub embroidery; press out water gently — do not wring.
Machine wash: turn inside out, use laundry bag, gentle/delicate cycle, cold water (≤30°C), low spin; wash away from abrasive items.
Dry: lay flat or hang inside-out in shade with good airflow; avoid prolonged direct sunlight (excessive UV speeds pigment aging).
No bleach: do not use chlorine bleach, strong oxidizers, high-heat tumble dry or aggressive solvent dry-cleaning.
How long will the photochromic effect last?
Practical guidance: Expect visible performance for 2–3 years under typical mixed indoor/outdoor use; take extra care (shade drying, gentle wash) to maximize longevity.
Why might the effect fade or weaken?
Main causes of fading: prolonged/intense UV exposure, high-temperature treatments, strong chemical exposure (harsh detergents/bleach), heavy abrasion, and normal photo-fatigue of pigments. Embedding photochromic compounds into yarn rather than surface coatings improves resistance — but aging still occurs over many UV cycles. We recommend care steps above to slow degradation.
Is embroidery safer than prints?
Yes — and it’s also more refined and more durable.
Lower surface chemical exposure: Prints often rely on surface inks or coatings that can leave residues; embroidery embeds colored or functional yarn into the fabric itself, reducing contact with surface-applied chemicals.
Less peeling & particle shedding: Printed designs can crack, peel or shed micro-fragments after repeated washing; embroidery is stitched into the textile and is far less prone to these failures.
Better longevity & tactile depth: Stitching and thread-direction create texture and sheen that last longer under wear and washing compared with flat prints.
Still verify materials: Safety depends on the thread/ink supply chain and testing — we source compliant dyed & photochromic yarns and keep third-party test summaries (e.g., OEKO-TEX, CNAS reports) available on request.
What tests / certifications do you have?
We keep test summaries for fabric functions (antibacterial, mite resistance, cooling index, negative-ion emission, moisture-wicking) and for color-response/durability where available. Full reports from accredited labs can be shared on request.
Any tips to maximize lifespan of photochromic effect?
Avoid prolonged intense UV, wash gently, dry in shade, avoid bleach/harsh chemicals, store folded in a cool dark place when not used frequently. Rotate wear to reduce continuous UV exposure.
Is the embroidery hand-made? How many stitches?
Our designs use Su embroidery techniques; heavy embroidered pieces are hand/hand-assisted and can exceed 1,000,000 stitches on a single item.
How long before my order ships?
