WHAT IS TiO2-FREE BRIGHT FIBER?
TiO2 (Titanium Dioxide) is commonly used as a whitening agent in conventional polyester fiber.
Our TiO2-free process delivers a naturally bright fiber with cleaner composition and superior performance.

Cleaner composition, Higher Purity
Conventional fiber with TiO2,
Contains whitening agent
Safer choice
TiO2,-free, reduces potential migration risk
Higher potential risk
TiO, may migrate under specific conditions
Higher tenacity
Better strength retention under high-speed sewing
Lower tenacity
Strength loss more easily under stress
Stable sewing
Low fuzz, fewer breaks, consistent stitch quality
Less stable
higher breakage risk, uneven stitches
Clean & bright
Premium look for high-end packaging
Dull appearance
Grayish tone affects packaging image
Lower extractables
Better chemical stability and compatibility
Higher extractables
More impurities and potential residuals
