Test Method 15-2009, and AATCC Test Method 107-2009, respec- tively. The physical properties of tensile strength, tearing strength, and stiffness in terms of bending length and flexural rigidity of the fabrics were measured according to ASTM D 5034-09, ASTM D 1424-09, and ASTM D 1388-96, respectively.
