Abstract The main content dealt with in the paper is to analyze effects of
structural parameters on compression property of spacer fabrics.
Based on compression stress and strain curves, four characteristic
indices are featured, which include compression work, recovery ratio
of compression work, maximum compression force when compression
strain is 0.7 and secant modulus by fitting compression stress --
strain curve from strain 0 to 0.25. Experimental results show that
structural parameters of spacer fabric, including thickness of
spacer fabric and diameter, angle, arrangement shape and density of
spacer filament, significantly influence compression behaviour. With
the thickness of specimen increasing, compression work increased,
while the compression secant modulus and maximum force decreased,
and the recovery existed nonlinear relationship and showed a
relatively optimal thickness. Compression work, recovery ratio,
maximum force and secant modulus existed the same ascending trend
when the diameter of spacer filament increased from, while they
showed descending trend when spacer angles decreased. The whole
structure of spacer fabric was more stable when the arrangement of
spacer filament is X-shaped than V-shaped, and the compression
work, recovery ratio, maximum force and secant modulus of sample X
shape were all larger than those of sample V shape. As for the
density of spacer filaments, the compression work, maximum force and
secant modulus increased with density decreased, while the recovery
ratio of spacer fabric with higher density was smaller than that of
smaller density.
