      Sunward Growth — Su-Embroidered UV-Reactive T-Shirt - SunnySass

      Sunward Growth Tee — Let botanical layers wake with sunlight.

      This piece fuses generational Su-embroidery with contemporary photochromic finishes. Each tee is hand-stitched by artisans trained in Su embroidery techniques, with needle counts typically exceeding 1,000,000, sculpting layered botanical textures that subtly shift as daylight hits selected threads.

      <h2>Heavy Su embroidery</h2>

        Heavy Su embroidery

        We’ve engineered a mint-cooling fabric specifically to support heavy embroidery — composition 60% Cotton / 40% New Polyester — balancing robust stitch support with summer comfort. The fabric delivers quick-dry, antibacterial, mite-resistant, cooling yarns and negative-ion benefits for everyday performance.

        UV reactive T-shirt

        Under sunlight or UV, targeted photochromic areas reveal a warm golden gradient that converses with the embroidered texture — a wearable micro-landscape that transforms with light. As this is a labor-intensive limited artisan-made piece, production is constrained. Please follow care instructions to preserve both the photochromic effect and the embroidery.

        Sunward Growth — Su-Embroidered UV-Reactive T-Shirt - SunnySass

        Mint-Tech Fabric — Built for Embroidery & Sunlight

        Sunward Growth uses a mint-cooling technical knit engineered for heavy Su embroidery (60% Cotton / 40% New Polyester). The fabric balances stitch-support with all-day comfort:

        • quick-dry
        • antibacterial
        • mite-resistant
        • cooling
        • negative-ion

        Tested & Verified — Performance You Can Trust

        Our products have passed multiple industry-standard performance tests (test summaries available on request), covering key next-to-skin and functional metrics:

        • Antibacterial performance — top-rated test result, reducing bacterial residues.
        • Mite-resistance — textile mite-resistance evaluation passed for improved wear hygiene.
        • Cool-to-touch coefficient — proven cool-to-touch performance in lab tests.
        • Negative-ion emission — measured and meets test criteria for ion output.
        • Moisture-wicking & quick-dry — effective sweat transport and fast evaporation confirmed.

        CLEANING — Quick Guide

        Hand Wash

        Use cold water or under 30°C, a mild neutral detergent, and gently soak and lightly agitate. Do not rub embroidery aggressively. Press out water gently — do not wring.

        Machine Wash

        Turn garment inside out, place in a laundry bag, use delicate/ gentle cycle, cold water (≤30°C) and low spin. Wash separately from rough items that could abrade embroidery.

        Drying

        Lay flat or hang inside-out to dry in shade and good ventilation. Avoid prolonged direct sunlight — extended UV exposure can accelerate gradual loss of photochromic performance.

        Avoid

        Do not use chlorine bleach or strong oxidizing cleaners; avoid high-heat tumble drying or aggressive dry-cleaning solvents.

        Frequently Asked Questions

        Is this a unisex fit?

        Yes. Sunward Growth and the collection use a unisex cut designed to suit all genders. For a standard fit choose your usual size.

        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 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.

        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).

        Avoid: do not use chlorine bleach, strong oxidizers, high-heat tumble dry or aggressive solvent dry-cleaning.

        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.
