وصف المنتج: EVERYGLOW® Glow in the Dark Polyester Yarn
1. Overview
EVERYGLOW® Glow in the Dark Polyester Yarn represents the pinnacle of luminous textile engineering. Unlike surface-treated fibers, our glow in the dark polyester yarn is manufactured using a “solution-dyed” method where high-purity photoluminescent pigments are integrated directly into the molten polyester polymer before extrusion. This results in a high-tenacity, industrial-grade yarn that serves as a self-sustaining light source, glowing for 6+ hours after a brief exposure to ambient light.
Designed for weaving, high-speed sewing, and industrial knitting, this yarn is the foundational component for safety textiles, performance outerwear, and innovative interior design.
2. Key Features
- Molecular Integration: The photoluminescent crystals are embedded within the fiber core. This ensures the luminosity is permanent and cannot be removed by abrasion, heavy use, or chemical cleaning.
- High Tenacity & Low Elongation: Engineered to withstand the rigors of industrial looms and circular knitting machines without snapping or stretching out of spec.
- Exceptional Afterglow Performance: Utilizing rare-earth doped strontium aluminate (SrAl2O4:الاتحاد الأوروبي, Dy3+), the yarn exceeds الدين 67510 Class A standards for brightness and decay time.
- Thermal Stability: Formulated to maintain structural integrity and luminescent efficiency during heat-setting processes up to 180°C .
- Eco-Conscious Safety: 100% free from radioactive isotopes, formaldehyde, and heavy metals. Safe for prolonged skin contact and OEKO-TEX® compliant environments.

4. Industrial Applications
- Safety Textiles: High-visibility webbing, safety nets, and emergency egress carpets.
- Outdoor Gear: Tents, paragliding cords, and backpacks for enhanced nighttime search-and-rescue visibility.
- Automotive Interiors: Luminous stitching for door panels, floor mats, and seat belts.
- Broadcloth Weaving: Production of glow-in-the-dark fabrics for upholstery and heavy-duty apparel.
5. Textile Engineering Tips
- Fabric Density: To maximize the “charge and discharge” efficiency, we recommend a slightly lower weaving density than standard polyester. This allows the photoluminescent crystals within the fiber to “breathe,” increasing the surface area exposed to charging light.
- Dyeing & Finishing: If piece-dyeing fabrics containing EVERYGLOW® Glow in the dark polyester yarn, use transparent or light-colored dyes. Darker dyes act as a “light shield” and will significantly reduce the afterglow intensity.
- UV Exposure: While UV-stabilized, prolonged exposure to extreme outdoor UV radiation (e.g., permanent marine use) should be monitored for fiber degradation over 5–7 years.
6. Care & Handling
- Washing: Industrial wash resistant. Can withstand high-temperature laundering up to $60^\circ\text{C}$.
- Chemicals: Resistant to most acids and organic solvents. Avoid concentrated oxidizing agents.
- Storage: Store in a cool, dry place away from direct sunlight to maintain the long-term efficiency of the light-storage pigments.
