Flat bright yarn
The upper and lower sides of the cross section of polyester flat yarn have concave and convex grooves. Because of polyester flat yarn, on both sides of surface has concave and convex grooved, once woven into the fabric, the fabric has both through grooves on the surface of the flat yarn to fulfill hydrophobic dehumidification function, and due to the between yarn and yarn, overlapping between layer and layer formed millions of air room, so that millions of interconnected three-dimensional space formed in the small room in the fabric has good air permeability; In addition, in the case of dry fabric, the small room in the fiber net has a certain temperature insulation performance. The above flat polyester yarn can be used to make high-grade sportswear fabric and down jacket lining material.
We are Flat Bright Yarn manufacturers and suppliers, we work closely with textile manufacturers, designers, and brands to develop customized polyester yarns that meet their specific needs. This may involve collaborating on product design, testing and refining yarns to meet specific performance requirements, and providing technical support and guidance throughout the production process.
Flat bright yarn is a specialized type of smooth, non-textured polyester filament yarn known for its high luster, uniform structure, and excellent processability. Unlike textured or dull yarns, it maintains a sleek, reflective surface, making it ideal for applications where shine, drape, and a premium finish are desired.
Key Technical Characteristics of Flat Bright Yarn
| Property | Technical Description | Functional Benefit |
| Fiber Structure | Smooth, non-textured filament (FDY type) | Eliminates bulkiness while maintaining filament integrity |
| Surface Morphology | Geometrically circular cross-section with optical brightening treatment | Provides consistent light reflection and premium visual appearance |
| Linear Density | Available in standardized deniers (75D-300D) with ±1% CV | Ensures uniform fabric density and predictable performance in conversion processes |
| Tensile Strength | 4.5-6.0 g/denier (standard) with elongation of 15-30% | Withstands high-stress weaving processes without filament breakage |
| Thermal Stability | Heat setting temperature range: 180-210°C | Maintains dimensional stability during downstream thermal processing |
| Dyeability | Modified polymer with -COOH end groups for enhanced dye uptake | Achieves 95%+ dye exhaustion with acid/complex dyes |
| Friction Coefficient | 0.20-0.25 (yarn-to-metal) with silicone finish application | Reduces abrasion in high-speed warping and knitting operations |
| Optical Properties | 85-90% light reflectance (ASTM E430 standards) | Creates superior luster without requiring post-treatment |
| Moisture Regain | 0.4% at standard conditions (20°C, 65% RH) | Minimizes hygroscopic expansion during processing |
| Yarn Evenness | Uster CV% < 0.8 (Class 1 standard) | Eliminates barre effects and ensures uniform fabric appearance |
