Abstract

Mechanical properties measured by tensile test of Nylon‚Ufibers with various diameters have been examined in standard, wet, water-immersed and water-immersed by JIS conditions. Tensile test in wet condition was performed under JIS L‚P‚O‚R‚O. Tensile test in water-immersed condition was applied to the fibers dipped in water. Diameters of the fibers used for the tests were‚QD‚Qand‚QD‚Xisuper micro fiberj,‚XD‚Pimicro fiberj,‚Q‚S and‚W‚Qinormal fiberjƒΚm. An influence of water evaporation to the mechanical properties measured in wet condition has been discussed, compared with those obtained in water-immersed and water-immersed by JIS conditions.

Key words : super micro fiber, micro fiber, normal fiber, tensile property, tensile test
