半導體作業的作業型態與人員需長時間的穿著無塵服，無塵服的透氣性與透濕性都直接影響現場作業人員的舒適性，所以在穿著無塵服時的舒適性與內層衣服機能性兩者間的協調下，就需要加以評估與分析，以期達到最佳的穿著舒適性。故本研究主要目的在探討半導體廠無塵室中無塵服的穿著對現場工作人員的生理與心理之影響。本研究共有兩個主要實驗：
實驗一的部分乃針對穿著無塵服之透氣性和透濕性的設計，對於人員生理與心理反應之影響進行探討，共計10位受試者參與實驗，結果指出當穿著較高透氣性與較高透濕性的無塵服時，有顯著較低的皮膚溫度、微氣候溫度與微氣候濕度(P<0.01)；隨著工作時間增加，微氣候溫度也會隨之增高，微氣候濕度則是剛開始會降低，然後隨著時間增加而上升；受試者主觀反應方面，也與客觀反應有著一致的結果。
實驗二的部分則是進一步探討穿著無塵服與不同衣物特性的內層衣物下，人員穿著舒適性的影響，共計20位受試者參與實驗，每一位受試者皆穿著4種不同特性的內層衣物(包含100% 棉, 70% 棉 + 30% 聚酯纖維, 65% 聚酯纖維 + 35% 棉, 100% 聚酯纖維)來完成實驗，結果指出穿著100% 聚酯纖維的內層衣物將會顯著增加內側微氣候濕度(p < 0.01)，穿著100 % 棉的內層衣物時，將顯著增加內外側微氣候濕度(p < 0.01)以及衣物的回潮率。此外，混和成分的內層衣物將有較低的內外側微氣候濕度(p < 0.05)。主觀反應方面，穿著65% 聚酯纖維 + 35% 棉混和成分的內層衣物相較穿著70% 棉 + 30% 聚酯纖維混和成分的內層衣物有較高的主觀舒適度。
總結而言，本研究提供半導體廠在選擇與設計無塵服時有益的資訊，並且也指出內層衣物的特性 （吸濕、透濕） 與服裝舒適性有密不可分的關聯，故提出較佳的內層衣物組合，藉以增加無塵室人員穿著無塵服的舒適性。

The function of cleanroom clothing is to protect the product from contamination by people, and to dissipate electrostatic discharge. People in the cleanroom work environment often complain about the discomforts associated with the wearing of cleanroom clothing. This study investigates the effect of wearing cleanroom clothing on physiological and subjective responses. Two experiments have been designed. The first experiment is to investigate the effect of air permeability and water vapor permeability of cleanroom clothing on subject’s physiological and subjective responses. Ten subjects participated in this study. The results indicate that skin temperature, micro-climate temperature and relative humidity were lower while wearing cleanroom clothing with high air permeability and high water vapor permeability. As the task time increased, the micro-climate temperature also increased but the micro-climate relative humidity decreased at first and then increased. In addition, the physiological responses showed significant positive correlations with the subjective perception of clothing comfort.
The second experiment is to investigate the influence of the double-layer clothing in semiconductor manufacturing cleanroom environment. Twenty subjects participated this study. Each subject completed four treatment combinations with four different inner clothings (e.g. 100% cotton, 70% cotton + 30% polyester, 65% polyester + 35% cotton, 100% polyester). The results indicate that wearing 100% polyester inner clothing caused a significant increase in inner micro-climate relative humidity (p < 0.01). Wearing 100% cotton inner clothing caused a significant increase in both inner micro-climate relative humidity (p < 0.01), and inner clothing’s moisture absorption. Further, wearing the blending fiber inner clothing caused lower relative humidity in the inner and outer clothing micro-climate (p < 0.05). Moreover, wearing 65% polyester + 35% cotton inner clothing had higher subjective comfort than that of wearing 70% cotton + 30% polyester.
In summary, the findings of this study provide useful information for cleanroom clothing design and selection, and the moisture absorption and water vapor transportation characteristics of the inner clothing are the major factors affecting the comfort of wearing double-layer clothing.
