摘要 (文章匯總)
To evaluate the effectiveness of ventilation systems in outdoor jackets, two jackets were purchased and modified, one made of PTFE laminated fabric and the other made of polyurethane coated fabric. Six male subjects undertook exercise routines simulating fell walking while wearing these jackets. The skin temperature at four different locations and the amount of perspiration generated during exercise were recorded for analysis. The experimental results were analysed using two-way analysis of variance. From the analysis it was found that during the exercise the design of the pit zip openings, especially with pit zip openings at both sleeve and side seams, in a jacket has an effect on thermal regulation, limiting the rate of temperature increase; however, during rest it is the fabric that plays the more important role. The results for the period of exercise suggest that the provision of ventilation at appropriate positions in the jacket could contribute considerably to heat loss irrespective of the use of breathable fabrics.

Conclusions
From this research it is shown that both clothing system engineering and waterproof breathable fabrics can contribute to thermophysiological comfort in outdoor jackets when the jacket is worn for mixed activities such as fell walking and resting.

During the exercise the design of the openings in a jacket has an effect on thermal regulation, limiting the rate of temperature increase. In the case of both GE and PE jackets, a pit zip with both sleeve and side seam opening has the greatest effect on lowering skin temperature followed by sleeve opening, side opening and no opening.

During the rest period, however, it is the fabric that plays the more important role. A more rapid cooling effect is observed for GE jackets made of PTFE laminated fabrics than PE jackets made of polyurethane coated fabrics. The results for the period of exercise, however, do suggest that the provision of ventilation at appropriate positions in the jacket could contribute considerably to heat loss irrespective of the use of hi-tech fabrics.

Skin temperature at the back was greater than at other parts of the body where measurements were taken at the start of the exercise, but the skin temperature at the chest gave the highest reading during exercise. This suggests that an opening near the chest may be the most effective way of creating ventilation. Although several outdoor jacket manufacturers in the UK incorporate a ventilation system around the chest, it is not the most popular position to open during exercise, since it directly exposes the chest to the outer environment. It is recommended, however, to consider engineering a design using a chest opening while minimising direct exposure.

In terms of moisture retention the PE jacket was seen to create more discomfort than the GE jacket. Measurements showed a greater amount of sweat being absorbed by the cotton T-shirt and blotting papers for PE jackets than GE jackets.
