R&D & INNOVATION
EVOLUTION OF FIBER TECHNOLOGY INSPIRED BY NATURE
FROM POLYESTER CHIP TO ENGINEERED SLICE
Every functional fiber starts at the slice level. We perform high-resolution cross-sectional imaging on raw polyester chips before and after solid-state polycondensation (SSP).
Each slice reveals three critical parameters for downstream spinning
Internal Crystallinity
Ensures thermal stability during extrusion
Moisture Content
(≤30 ppm)
Ensures thermal stability during extrusion
Additive Particle
Dispersion
Pre-validates masterbatch compatibility
BEYOND CIRCULAR
HOLLOW & PROFILED CROSS-SECTIONS TECHNOLOGY
Our proprietary non-circular yarn cross-sections, including hollow and cruciform profiles, are visualized and validated via Scanning Electron Microscopy (SEM).
| Cross-Section | Functional Mechanism | End-Benefit |
| Hollow | Trapped still air reduces thermal conductivity; reduced mass per unit length | Thermal insulation & lightweighting |
| Cruciform | Surface micro-channels accelerate capillary wicking; modified light reflectance reduces harsh luster | Moisture wicking & soft lus |
BIO-BASED & MOLECULE-ENGINEERED ADDITIVES
We develop and compound functional masterbatch at the molecular level, not just mixing. Below are active solutions validated for fiber extrusion
*All masterbatch are twin-screw compounded with controlled particle size (D90 < 1.5μm) to avoid spinneret clogging*
