OEKO-TEX Standard 100 certification relates to restricted-substance testing for textile materials. It does not certify conductivity or RF shielding performance. Ask YUNJIA TEXTILE for available material documentation before selecting yarn for a specific textile project.

Metallic yarns are tested by independent laboratories to confirm metal content, conductivity, and functional performance. These evaluations ensure consistent quality and dependable electrical behavior when incorporated into technical textile structures

FAQ
Why does the price of silver yarn fluctuate?
Silver yarn is plated with 99.9% pure silver, making its cost closely linked to global precious metal market prices. As silver prices change, the material cost adjusts accordingly.
How long is one spool of yarn?
Yarn length is determined by its net weight and denier (linear density).
Denier represents the weight in grams per 9,000 meters.
The approximate length can be calculated as:
Length (m) = (Net Weight × 9000) ÷ Denier
For example, a 260D yarn with 100g net weight equals approximately 3,460 meters.
How should metallic yarn be stored?
Most metallic yarns can be stored under normal dry indoor conditions, away from moisture and direct sunlight.
For silver-plated yarns, we recommend storing in a cool, dry environment with minimal humidity exposure to reduce surface oxidation. Keep sealed when not in use for best preservation.
