Taking the back waist as an example, the regression equations based on different
subjective perceptions, air gap thickness and surface temperature could be established
(Table 5). It is shown that when air gap thickness increases, damp, sticky and muggy
sensation becomes weak. On the other side, subjective sensation increased with the
increasing of surface temperature.

Note: In regression equation, Z is subjective votes; X is air gap thickness; Y is clothing surface
temperature.
Q type cluster analysis was used to deal with subjective votes of damp, sticky and
muggy sensations. The results (Table 6) show that 9 experimental garments could be
divided into three groups: 1 and 2 with relatively thin air gaps; 3, 4, 5 and 6 with
medium air gaps; 7, 8 and 9 with thick air gaps. Different air gaps resulted in different
subjective sensations. Garments 3, 4, 5 and 6 had the highest comfort votes; garments
1 and 2 had moderate votes, while garments 7, 8 and 9 had the lowest votes (Figure
2). Thus, correct fit is an important factor to the general comfort sensation of clothing.
