| 摘要: | 潛水活動裡，穿著潛水衣時之“保溫功能”，影響潛水時間與深度。在潛水衣複合織物當中，發泡材之厚薄會決定一部分保溫效果，不過為減低複合織物重量以及增加穿著之方便性、活動性，當發泡材厚薄固定時，貼合上方之針織織物為影響複合織物保溫性之關鍵。
於現今之各項保溫系統檢測當中，皆以成衣為主，適用穿著於陸地上之服裝，但潛水衣需考量海水溫度以及含水份之不同因素，影響保溫性，因此本實驗為模擬穿著潛水衣因應之外界環境條件，加以測試。
實驗主要分為兩階段，一為穿著潛水衣未下水之無水份狀態下，以及穿著潛水衣潛水之含水狀態，進行探討。首先將各針織布貼合於發泡材料上，成為複合織物，接著複合織物裁片與黏合成樣本，將其包覆裝有40℃以上熱水之鋼瓶，再放置於恆溫恆濕箱中，設定溫度10±1℃、濕度65±5%，模擬乾態測試。在濕態測試當中，以自製儀器量測，將儀器內部裝水，水溫設定10±1℃，以模擬潛水外界環境，將裝有40℃以上熱水之鋼瓶同樣本放入儀器內。樣本於環境條件下，溫度量測儀得以測量鋼瓶內熱水降溫溫度，計算每分鐘平均降溫溫度，而分析複合織物保溫性。
經由本實驗得知，各項不同針織物條件，影響保溫性。在無水份時，布種樣本之間差異不大，保溫效果不明顯，而在濕態下，針織布之厚薄、紗絲選擇、組織等條件因素改變，對於保溫有較明顯之不同數據，並且得知布種A(尼龍原絲雙面組織)即使在乾的狀態下保溫性較差，但於含水份時，其保溫不見得為最差，因而顯現，水分對複合織物保溫性具有影響性。
透過實驗，顯示出布種G(特多龍原絲、尼龍原絲、彈性絲毛巾刷毛組織)能夠在乾狀態下得到最佳之數據，每分鐘平均最低降溫0.10℃，在濕狀態也有最好之效果，每分鐘平均降溫0.22℃，因而布種G選擇特多龍原絲、尼龍原絲、彈性絲運用之組織條件設定，即有最佳保溫性。
Diving activities, wearing wetsuit when the " warmth function", affecting the dive time and depth. Among the wetsuit composite fabric,foam material determines the thickness of the insulation part, but to reduce the weight and increase the wear composite fabric of convenience, mobility, when the foam material thickness is fixed, the fit at the top of the knitted fabric is affected the key composite fabric.
Now testing of the insulation systems which, tailor garmentsmainly for wearing apparel on land, but the wetsuit you need to consider different points seawater temperature and moisture factors that affect the insulation resistance, so this experiment is simulated wearing wetsuit in response to the external environmental conditions, to be simulated tests.
Experiment divided into two phases, one for not wearing awetsuit water, no water status, and wearing a wetsuit diving, whichcontain water status, were discussed. First, each of the knitted fabric is bonded to the foam material, become composite fabric, composite fabric pieces and then combined into a sample, it covered more than 40℃ hot water with the cylinder, then put into constant temperature and humidity chamber, Setting temperature 10±1℃, humidity at 65±5%, dry simulation tests. In the wet state tests, to homemade instrument measurements, the instrument internally filled with water, the water temperature setting 10±1℃, to simulate diving external environment, will be equipped with more than 40℃ hot water into the cylinder of the same instrument inside. Sample at ambient conditions, the temperature measuring instrument to measure the cooling water temperature within the cylinder, the average cooling temperature calculated for each minute, the heat retention of the composite fabric.
Learned through this experiment, the different knitted conditions that affect insulation.This study show the difference in water sharing, little difference between the samples of fabrics, thermal insulation effect is not obvious, but in the wet state, the thickness of the knitted fabric, silk yarn selection, organizational factors and other conditions change, for there are obviously different insulation of data, and that even in the dry fabrics a state of insulation is poor, but in aqueous sharing, the insulation is not necessarily the worst, and therefore show, water insulation of the composite fabric has an impact resistance knitted conditions that affect insulation.
Through experiments, showing that distributed species in the dry state G to get the best data, the average per-minute cool down 0.10 ℃, the best in the wet state also has the effect, the average per-minute cool down 0.22 ℃, thus fabrics G Select Tetoron raw silk, raw silk nylon, spandex organizational conditions for the use of the set, which has the best insulation. |
