Environmental Ergonomics XII Igor B. Mekjavic, Stelios N. Kounalakis & Nigel A.S. Taylor (Eds.), © BIOMED, Ljubljana <strong>2007</strong> 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.

The spacer fabrics with ribbed skin facing fabric surface and high spacer thread density have significantly higher F-values than the spacer fabrics with low thread density, and the spacer fabrics without wefts have significantly higher F-values than the spacer fabrics with wefts. The water vapor absorption (Fi) is an important thermophysiological textile property, particularly in situations with moderate sensible perspiration. The comparatively small standard deviations on the right hand of Figure 2 indicate that the water vapor absorption depends on the weft’s chemistry, and in this way on the weft construction. The spacer fabrics with wefts from hygroscopic viscose and cotton have got significantly higher Fi-values than the spacer fabrics with wefts from non-hygroscopic polypropylene, or the spacer fabrics without wefts (respectively). 3,5 1,6 not significantly textile construction weft construction significantly better 311 ribbed / low density medium range 294 fully fashioned / low density 0,4 0,4 CV CO - PP significantly worse 337 315 not significantly textile construction weft construction 310 300 - CO PP CV worse better worse better 135
