High Tenacity Low Shrinkage Optical White Polyester Filament Yarn

       High Tenacity Low Shrinkage Optical White Polyester Filament Yarn is a type of polyester filament that combines high strength, low thermal shrinkage, and high whiteness optical properties. Its core is used in scenarios where there are dual high requirements for material mechanical properties and appearance whiteness. It is an important category of functional polyester filament. This product is made of polyester (PET) as raw material and achieves three key properties through special spinning processes such as modified spinning and post-treatment shaping: high strength to ensure structural stability, low shrinkage to ensure size deformation, and high whiteness to meet optical grade appearance requirements. Mainly used in the fields of lightbox fabrics, projection screens, reflective materials, high-end decorative fabrics, etc., it needs to withstand certain tension, maintain stable form, and have excellent whiteness performance at the same time.
