Abstract
The creep characteristics of spun-bonded non-woven fabrics were investigated using a plane strain creep test.
200mm wide samples were used. Several light weight hinged rods were spaced on the sample. These rods are fitted with pins which pierce the fabric and resist contraction during the test. The test temperature was maintained at 20±2°C.
According to the test results, creep deformation characteristics varies largely with the type of fabrics. In the case of fabrics made from polypropylene, creep deformations increase rapidly as the applied stress level increase above 10 to 20 percent of the maximum tensile strength, but in the case of fabrics made from polyester, creep deformations do not increase largely below 60 percent of the maximum tensile strength.
