Semi-Dull Nylon 66 Filament Yarn 40D/12F for Sportswear
Product Description
This product is a high-quality Semi-Dull Nylon 66 Filament
Yarn, characterized by its specific denier and filament count
of 40D/12F. The "semi-dull" luster indicates a matte
appearance, achieved through a specialized TiO₂ (titanium dioxide)
content, which reduces light reflection and glare, resulting in a
more natural, soft-touch aesthetic compared to bright yarns.
As a Nylon 66 variant, it offers superior thermal
resistance, higher melting point, and better elastic recovery
compared to standard Nylon 6, ensuring excellent dimensional
stability during both processing and end-use.
