PHYSICAL AND MECHANICAL TESTING FOR LEATHERS
Leather physical testing mainly includes: tensile strength, elongation, tear strength, composite peel strength, abrasion resistance, folding fastness, color fastness (the color also includes dry rub resistance, wet rub resistance, sweat resistance, heat resistance, water fastness, washing resistance, stain resistance, etc.), air permeability, water permeability, dynamic water resistance, softness, horizontal flammability, atomization, odor, etc.
MECHANICAL TEST PARAMETERS AVAILABLE WITH FGT CPS
- FOR FAST SERVICES ADDITIONAL CHARGES WILL BE APPLICABLE:
- 24 HR SERVICE-2 x normal charges
- 48 HR SERVICE-1.5 x normal charges
