In order to confirm the validity of q_max, the maximum heat flux when a heat plate with constant heat touches fabrics, as an objective measure of warm/cool feeling, some sensory tests were carried out. Following two types of tests were adopted.
(1) Sensory tests using a metal heat plate to examine the basic characteristics of warm/cool feeling as sensory phenomena.
(2) Sensory tests on fabric warm/cool feeling to examine the relation between q_maxand warm/cool feeling ratings, influence of environmental temperature and effect of fabric surface structure. Following results were obtained.
(1) From the sensory tests using a metal plate, it is concluded that an imperceptible temperature of skin of hand (T_n) is determined by skin temperature (T_s) and Tn is 3-4°C lower than T_sand that difference threshold is 1-2°C at controll temperature 20-35°C. and it is recognized that difference threshold become worse when controll temperature become high near body temperature.
(2) From the sensory tests on fabric warm/cool feeling, following results were obtained.
(a) Correlation between gmaX and warm/cool feeling ratings is high.
(b) Perception of fabric warm/cool feeling become dull when an environmental temperature is near a body temperature.
(c) The critical thickness that fabric shows its own warm/cool feeling is about 1mm, and when thickness is lower than 1mm, judgement does not become so consistent.
These results support the validity of gmax, the maximum initial heat flux, as an objective measure of warm/cool feeling.

Three irons from different makers were tested on the basis of recommended iron-temperatures for several fibers. The results indicated that the gaps at the temperature-set point of dial gave rise to the temperature difference of 30 to 70°C, and the performances of two out of three irons used in this study were not so perfectly proper.
The changes of the temperature of cloth, the amount of remaining water in cloth and the glass transition temperatures of fibers during the ironing were investigated, and the mutual relations in these factors were discussed. Furthermore, the relation between an effective setting and the amount of remaining water was estimated from the degree of pleat retention. The order of effective setting in the combination systems of ironing and the state of cloth was as follows sprayed cloth-steam ironing>dried cloth-steam ironing>sprayed cloth-dry ironing>dried cloth-dry ironing.

The evaluation of the detergency has been carried out by the difference of surface reflectance of the specimens between before and after washing.
However, further investigations are required to evaluate the detergency.
Therefore, attempts have been made to apply the common principle of the gray scale for staining and color change to the evaluation of detergency.
And, we found a new method of the evaluation of detergency which was based on the rate of change of color depth.
The calculated formulas are as follows:
(1) When the detergency is represented in accordance with the grade of gray scale:
ND=5.5-ln [ {1-ΔC/ (Co-CW) } / (ω⋅KD) +1] /ln2
where ND: the calculated value of detergency.
ΔC: the color depth difference of specimens between before and after washing.
Co: the color depth value of specimens before washing.
CW: the color depth value of white cloth.
ω=0.37: scaling constant.
KD=0.125: the level constant of color shade.
(2) When the detergency is represented by percentage:
DN (%) =100-32.06×ln [ {1-ΔC/ (Co-CW) } /0.04625+1]
where DN: the percentage of detergency which is transformed from the ND.
