The L1-309 Black fabric represents a specialized category of solar control textiles that merge advanced engineering with deep, consistent coloration. This premium Sunscreen fabric from LEAPKA's L1 Thin Plain Weave series demonstrates remarkable technical capabilities through its carefully calibrated material composition and performance metrics, offering architects and designers a reliable solution for projects requiring both functional excellence and sophisticated dark aesthetics.

Material Composition and Structural Properties

The fabric's construction reflects detailed engineering and superior manufacturing standards:

Material Architecture: 30% high-tenacity polyester/70% PVC coating system. This precisely balanced ratio ensures optimal relationship between the structural strength provided by polyester fibers and the environmental protection delivered by advanced polymer coating technology

Surface Density: 450 g/m² ± 5%. This medium-weight classification provides excellent stability and longevity while maintaining flexibility for various installation scenarios

Physical Dimensions: Standard production widths of 200 cm (78 inches), 250 cm (98 inches), and 300 cm (118 inches) with consistent 35-meter roll lengths

Weave Characteristics: Fine plain weave pattern that ensures uniform appearance while maintaining reliable functional performance across the entire fabric surface

Optical Performance and Functional Attributes

The fabric's technical excellence is demonstrated through its precision engineering:

Openness Factor: 3% ± 0.5%. This carefully calibrated permeability establishes ideal balance between solar protection and visibility preservation, effectively reducing glare while maintaining outward views

Yarn Configuration: 56 × 46 thread count using 0.32 mm diameter high-quality yarns. This dense weave pattern ensures consistent performance and enhanced durability

Thickness: 0.60 mm ± 5%. The moderate thickness contributes to excellent rolling characteristics and long-term performance stability

Performance Certification and Quality Assurance

The material meets rigorous international standards for architectural textiles:

UV Protection: >92% UV radiation blockage (ISO 105-B02 compliant)

Thermal Regulation: 63% solar heat gain reduction (EN 14501 certified)

Fire Safety: Class B fire rating (EN 13501-1 certification)

Durability Testing: 3,200 hours accelerated weathering testing with minimal performance degradation

Manufacturing Compatibility

The material supports professional fabrication processes:

Cutting Methods: Compatible with precision cold knife cutting and specialized crush cutting systems

Seaming Technology: Excellent performance with thermal bonding and high-frequency welding techniques

Hemming Options: Suitable for industrial sewing methods using UV-resistant thread

This comprehensive technical profile establishes L1-309 Black as an exceptional Roller blinds Fabrics solution that combines advanced engineering with reliable performance characteristics, making it particularly suitable for architectural applications where both technical excellence and deep black aesthetics are essential requirements.
