TITANIUM DIOXIDE FOR YARN, FABRIC AND HOME TEXTILES: What’s Driving the Next Bright Leap

If you work with yarns or home textiles, you already know the quiet hero in the line: titanium dioxide. To be honest, I’ve seen mills argue about draw ratios for hours but agree in five minutes that a solid TiO2 grade makes or breaks whiteness, opacity, and UV durability. This textile-focused grade from Jindi Industrial Park, Dacheng County, Langfang, Hebei, is tuned for bright whites, consistent dye backdrops, and real-world weathering.

Industry trends (and what mills quietly ask for)

Demand is shifting toward dope-dyed and recycled fibers, lower VOC finishing, and OEKO-TEX compliance. Surprisingly, a lot of purchasing managers now benchmark not just whiteness L, but b drift after 40 hours of Xenon arc. Many customers say they’ll pay a small premium for stable dispersion in PET and PA6 masterbatch, because downtime is pricier than pigment.

Technical specifications (textile-grade, practical)

Process flow (how it fits the line)

Materials: PET, PA6/66, PP polymer chips; titanium dioxide pigment; dispersants; antioxidant pack. Methods: vacuum drying → twin-screw compounding into masterbatch → chip blending at spin line → metered melt feed → spin/draw/heat-set. Testing standards: ISO 591-1 and ASTM D476 for pigment classification; ISO 105/Xenon (B02) and AATCC 16 for light fastness; ISO 7724 for Lab; ISO 18314 for tinting; migration and fogging per VDA 278 for automotive textiles. Service life: indoor textiles 5–10 years; outdoor awnings/upholstery ≈3–7 years depending on UV index and finish. Industries: apparel, bedding, curtains, nonwovens, outdoor furniture, automotive headliners.

Advantages in textiles

• High brightness and hiding power—whites look white, even on recycled blends.
• Stable dispersion—fewer spinneret deposits, smoother filament surfaces.
• UV resistance—helps slow yellowing and preserves hand feel over time.
• Consistent lot-to-lot color; many customers say shade matching got visibly easier.

Vendor landscape (quick, practical)

Customization and packaging

Options include tuned PSD for PET vs. PA, hydrophilic/hydrophobic surface treatments, and masterbatch carriers (PET/PA6/PP). Packaging: 25 kg bags or big bags. Tech team can align dosage and screw profile; I guess that’s why start-ups stick around after trials.

Case notes and feedback

• Home linens (PET/CO blend): b improved from 1.6 to 0.9; claims fewer yellow returns after 6 months.
• Outdoor upholstery (PP): ΔE after 200 h Xenon down ≈18%; fewer chalking complaints, according to the finisher.
• Microfiber mop yarn: spinneret cleaning interval extended from weekly to biweekly—small win, big savings.

How to evaluate quickly

Run a 10–20 kg masterbatch trial; target 0.3–0.6% titanium dioxide in PET. Check L, b after heat-setting, haze on filament, and Xenon 24–48 h. If your b drifts, tweak residence time and dryer dew point first—then pigment dosage.
