Abstract
Mechanical properties for four Nylon6 fibers of different diameters have been examined. The diameters of the fibers are 82, 24, 9.1(micro-fiber), and 2.5(super-micro-fiber)μm. The apparatus for the tensile test has been newly designed for measuring the mechanical properties of the super micro fiber. The breaking forces measured for many super micro fibers have been grouped into those with large and small values. The distribution of the breaking forces has been correlated to the distribution of the diameters. The super micro fiber has finally been clustered into five groups in order to evaluate mechanical properties. The breaking strength, breaking strain and the elastic modulus of super micro fiber at standard state were similar to those at wet.
