Fiber spinning manufacturer (PET, PA, PP)
TiO2 for Synthetic Fiber Producers
Synthetic fiber delustering uses 0.3–0.5% anatase. SEMITI A100 / A200 with low metallic impurity prevents spinneret fouling.
Typical volume
100–1000 t/year per fiber producer
Qualification cycle
8–12 weeks (spinning trial required)
Business context
Synthetic fiber producers — Indorama, Hyosung, Reliance Industries, regional producers — make PET / polyamide / polypropylene fibers for textiles, technical applications, and conversion. TiO2 added to spinning melt for matte hand-feel.
Procurement challenges
- 01Spinneret fouling prevention (very fine particles, no agglomerates)
- 02High-draw spinning compatibility (4x+ draw ratios)
- 03Low metallic impurity to avoid corrosion of spinning equipment
- 04Pre-dispersion in polymer melt
What SEMITI brings
SEMITI A100 universal anatase or specialized SEMITI A100-FB (fiber-bright sub-grade) for premium spinning. Pre-dispersed concentrate options available.
Recommended SEMITI grades for synthetic fiber producers
SEMITI A100
anatase · sulfate
Universal Anatase
Universal anatase grade for inks, paper, fiber and rubber — bright white with soft, easily-dispersed crystal.
SEMITI A200
anatase · sulfate
Rubber & Fiber Anatase
Anatase for white tire sidewall, EPDM, synthetic fiber delustering — soft crystal, low equipment wear.

Common questions
Why does spinneret foul with some TiO2?+
Coarse particle tail (D90 > 0.8 μm) or metallic impurities accumulate at spinneret holes. SEMITI A100 with tight PSD control prevents this.
