The sample groups 1 to 3, which are combined according to the textile construction,
contain in each case four spacer fabrics with identical textile constructions, but with
different weft constructions. The sample groups 4 to 7, which are combined according
to the weft construction, contain in each case three spacer fabrics with identical weft
constructions, but different textile constructions. The thermophysiological
characteristics of the spacer fabrics obtained from the Skin Model measurements were
summarized for every sample group due to computing the mean values and standard
deviations. With this analysis procedure, the standard deviations have the meaning of
an absolute measure that indicates the influence of a considered textile or weft
construction on the thermophysiological properties of the spacer fabrics. Small
standard deviations indicate a considerable influence, and wide standard deviations a
poor influence.
RESULTS
The water vapor resistance (Ret) is an important thermophysiological textile property,
particularly in wearer situations with insensible perspiration. The comparatively small
standard deviations on the left hand of Figure 1 indicate that the water vapor
resistance depends on the textile construction. Due to their smaller thickness, the
spacer fabrics with the high spacer thread density have significantly lower Ret-values
than the spacer fabrics with low spacer thread density.
