Office Chair Mesh Fabric Test

The test of office chair mesh fabric mainly involves four aspects: material and craftsmanship, mechanical properties, elastic recovery rate, and durability and lifespan.

Material and Craftsmanship: There are significant differences in the craftsmanship characteristics of mesh fabrics made from different materials. The US-patented Matrex mesh fabric is made of a special polyester-based elastomer material, produced through jacquard weaving with fluorescent anti-counterfeiting threads, and has passed BIFMA certification. The domestically produced Longwente mesh fabric is woven with high-density nylon threads to form a double-layer dragon-pattern texture, focusing on hard support. The U-mesh fabric is woven in a crisscross pattern with TPE elastomer embedded to form a four-way stretch structure, offering excellent cost-effectiveness.

Mechanical Properties: The core indicators include tensile strength, elongation at break, tear strength, etc. The air permeability of high-polymer elastic mesh fabric should be ≥300mm/s, with a tensile strength ≥800N/5cm, while ordinary mesh fabric usually has a tensile strength ≤400N/5cm. The Matrex Quantum 4.0 has an abrasion resistance of over 50,000 cycles, meets the CA117-Section E flammability standard, has a lightfastness rating of 5 (over 40 hours of light exposure), a wet rub fastness of 4.5 and a dry rub fastness of 5, and has passed BS 5852: e4 certification.

Elastic Recovery Rate: This reflects the mesh fabric's ability to remain comfortable after prolonged sitting. The Matrex mesh fabric has an instantaneous rebound rate (20% strain) of 97%, with a deformation residue of <4% after 2 hours of compression, a recovery rate of >93% after 10,000 cycles, and a hysteresis loss of 0.12. The U-mesh fabric has an instantaneous rebound rate of about 90%, with a deformation residue of about 8% after 2 hours of compression, a recovery rate of about 85% after 10,000 cycles, and a hysteresis loss of 0.20. The Longwente mesh fabric has an instantaneous rebound rate of about 86%, with a deformation residue of about 12% after 2 hours of compression, a recovery rate of about 78% after 10,000 cycles, and a hysteresis loss of 0.25.

Durability and Lifespan: These require testing for fatigue resistance, aging resistance, and structural stability. The BIFMA X5.1 standard requires office chairs to pass a 300,000-cycle compression test, with high-quality mesh fabric maintaining its shape integrity. The Matrex mesh fabric has passed an impact test of over 120,000 cycles and has obtained BIFMA certification. The U-mesh fabric has an impact test of about 80,000-100,000 cycles, with slow elastic degradation. The Longwente mesh fabric has an impact test of about 60,000-80,000 cycles, offering good wear and impact resistance.
