Nighttime reflective materials are used to produce high-visibility workwear for traffic police and sanitation workers.

Nightglow fibers are actually a type of functional fiber created by incorporating rare-earth luminescent materials during the spinning process. These fibers absorb energy from natural light, daylight lamps, and other light sources, then slowly release it in dark environments.

Common types of luminous yarns include: glow-in-the-dark filament yarn, which boasts high intensity and can be directly used for weaving and embroidery; glow-in-the-dark staple fiber yarn, ideal for blending with other fibers (such as cotton or silk) to create a softer, more luxurious hand feel; and glow-in-the-dark sewing/embroidery thread, known for its excellent wash resistance and outstanding light-absorbing performance, making it perfect for crafting intricate patterns.

Characteristics of night light:

1. Optical Properties

Spontaneous fluorescence and long-lasting phosphorescence: Key features. No external power source required—automatically "charges" during the day or under light, then glows naturally in the dark. High-quality nightlight products can maintain phosphorescence for 8 to 12 hours.

Colorful luminescent hues: The most common is yellow-green light (which is most sensitive to the human eye and delivers the best visual effect), but by adjusting the luminescent materials, you can also achieve blue, teal, purple, and other vibrant light effects. It’s important to note that the fiber’s natural color (as seen under daylight) may differ from its emitted luminescent color.

2. Physical and Mechanical Properties

Spinnability and processability: The luminescent filament boasts high strength, making it suitable for direct weaving; meanwhile, the luminescent staple fiber can be blended with other fibers—such as cotton, wool, polyester, and silk—much like cotton or wool, enabling the production of a wide variety of fancy yarns and significantly expanding the scope of product design.

Durability: Since the luminescent material is embedded within the fibers rather than applied as a surface coating, its luminous performance remains resistant to washing and abrasion—and its lifespan far exceeds that of glow-in-the-dark coated fabrics. While the luminous effect may gradually diminish after repeated washing or exposure to sunlight, it still outperforms coated products.

3. Safety and Environmental Friendliness

Safe and Non-Toxic: Modern rare-earth luminescent materials are non-radioactive, harmless to both humans and the environment, and meet the eco-friendly and safety standards for textiles.

Eco-friendly and energy-efficient: As a passive luminescent material, it consumes no electricity and can replace certain low-illumination lamps in emergency and signage applications, delivering significant energy-saving benefits.

4. Chemical Stability

It exhibits excellent chemical resistance, demonstrating a certain level of resilience against common acids and bases, with stable performance suitable for a wide range of environments.

Applications of night light sources:

1. Safety Protection and Emergency Management领域

Professional safety workwear: uniforms worn by traffic police, sanitation workers, highway maintenance personnel, and firefighters. These garments are highly visible under car headlights, significantly enhancing safety during nighttime operations.

Fire emergency signage: Used to create safety exit signs, evacuation route maps, fire hydrant location markers, and more. In adverse conditions such as power outages or heavy smoke, these signs provide critical visual guidance.

Outdoor safety gear: tents, backpacks, life vests, and glow-in-the-dark stripes on helmets—perfect for quickly locating yourself in nighttime outdoor environments.

2. Apparel and Home Textiles Sector

Fashion apparel: Used to create evening gowns, stage costumes, trendy hoodies, and footwear accessories, these pieces leverage techniques like knitting and embroidery to craft dynamic visual effects—subtle yet striking during the day, and utterly stunning after dark.

Functional home textiles—such as glow-in-the-dark curtains (providing a soft, guiding light when getting up at night), rugs, and sofa cushions—enhance convenience.

Knitted garments: Sweaters, scarves, and more crafted from luminescent yarn—warm and full of creativity.

3. Industrial Textiles and Specialized Fields

Transportation: Emergency guidance systems inside aircraft, high-speed trains, and ships, such as seat numbers and aisle indicators.

Architectural Decor: Weave nighttime light into wall fabrics and decorative paintings to create a unique indoor ambiance.

Military and Public Security: Used for nighttime identification on military maps, special markings, and individual soldier equipment.

4. Sports, Leisure, and Toys Sector
