The athleisure trend has blurred the boundaries between functional wear and leisurewear. Functional wear is no longer a niche market, but in the rapidly growing apparel market, it is now seen as a sector in its own right. What is high-performance textiles? High-performance textiles are engineered fabric for multiple-function garments. The performance of textiles is enhanced by a number of processes like the selection/blending of fibers, chemical processing, and finishing in different production stages by dyeing, coating, and laminating. Consumer Awareness and Claim Substantiation When purchasing an item of functional wear or athleisure wear, consumers consider garment function, performance, comfort, value for money, and brand reputation in their buying decisions. Brands should ensure the functional claim(s) of the product in the marketplace must meet the performance requirements for which they are designed and therefore fulfill client expectations. Benefits of Functional Wear Testing from SGS With our state-of-the-art functional testing equipment and expertise, we can help to substantiate product claims by testing fabrics, fabric systems and finished garments to determine their performance during the outdoor and sporting activities for which they are designed. Our service capabilities include: Easy careWear comfortProtectionHealthcareE-Function By helping you comply with national and international regulatory requirements, SGS ensures the quality, safety, and sustainability of your products.

🎨 JEFFREY LEUNG EYEWEAR DESIGN Launches Premium Color Dyeing Service for 3D Printed Eyewear Components

At JLX EYEWEAR, we've redefined what's possible in 3D printed eyewear finishing. Our proprietary post-processing technology transforms raw printed frames into luxurious wearable art, achieving a matte-shiny surface quality that sets new industry standards. These eight detailed close-ups reveal the meticulous craftsmanship behind every JLX EYEWEAR private label piece - notice how light dances across the perfectly balanced matte base while subtle luminous highlights accentuate each curve and contour.  Our multi-stage finishing process begins with precision mechanical polishing to eliminate all visible layer lines, followed by specialized chemical treatments that create the perfect matte foundation. The frames then undergo our signature coating application, where nano-level particles are carefully layered to build depth and dimension into the surface. The final hand-finishing stage ensures every millimeter meets our exacting standards, resulting in a tactile experience that feels as premium as traditional luxury materials.      What makes our finishing truly revolutionary is how it maintains structural integrity while achieving visual perfection. The matte surface provides sophisticated understatement, while the controlled shine adds dynamic energy that changes with movement and lighting. This proprietary technique allows for unprecedented consistency across entire collections - whether producing fifty or five hundred frames, each piece maintains identical surface characteristics.    For brands partnering with JLX EYEWEAR, this finishing technology opens new creative possibilities. Our process works seamlessly with complex geometric designs that would be impossible to finish conventionally, while offering customizable sheen levels from soft satin to high-contrast matte/gloss combinations. The result is eyewear that feels substantial yet lightweight, looks handcrafted yet technologically advanced.   Explore the future of 3D printed eyewear finishing at www.jeffreyleungeyeweardesign.com and discover how our surface technology can elevate your private label collection.  #JLXFinishing #MattePerfection#3DPrintedLuxury#EyewearInnovation#SurfaceTechnology#LuxuryFinishes#PrivateLabelExcellence#FutureOfEyewear
