Abstract
The anisotropic properties in tensile and creep behavior of needle-punched nonwoven fabric are studied in this paper.
The influences of specimen width and direction of fiber distribution on the tensile behavior of needle-punched nonwoven
fabric are experimental analyzed. The result shows that the specimen width has important influence on tensile behavior.
The anisotropic creep behavior of needle-punched fabric i.e., the influences of stress and the angle with the machine
direction (MD) on creep is investigated. The relationship between creep elongation and time at different stress and
different angle with the machine direction (MD) of needle-punched fabric are obtained by applying linear fitting and the
empirical model for calculating creep elongation are deduced. The result has an important meaning for predicting the
mechanical behavior, such as tensile, creep and relaxation behavior of needle-punched nonwoven fabric and reducing
experimental expense and difficulty.
