摘　　要：为探究干态织物与湿态织物在达到同等皮肤冷却时所产生的触觉感知是否一致,设计了3组皮肤冷却下的对照实验。通过对比各组织物在与皮肤动态接触下的冷/暖、光滑/粗糙、干/湿感觉评分,分析了感知差异产生的原因。结果表明:在皮肤冷却至0.9℃和1.2℃条件下,干织物的冷感显著强于同组湿织物;在皮肤冷却至0.9℃条件下,织物的光滑/粗糙感、干/湿感评分不存在显著差异,说明此时织物的干湿状态不足以使光滑/粗糙感和干/湿感产生显著变化;在皮肤冷却至1.2℃和1.4℃条件下,湿织物的光滑/粗糙感、干/湿感显著强于同组干织物,说明织物含水量较大时,与皮肤的黏附力增加,进而增强了粗糙感和湿感觉。因此,无水参与的情况下,干织物通过降温可以产生湿感觉。但仅降低干织物的温度,其湿感强度仍低于同组湿织物。Objective The production of skin moisture perception does not necessarily require water;however,contact with dry and cold fabrics can also induce a wet perception due to skin cooling.Nevertheless,no comparative analysis of the subjective feeling when using the same fabric with consistent skin cooling has been proposed.This research aims to explore the influence of dry and wet fabrics on subjective perception by controlling for an equal amount of skin temperature drop.Method The pre-test determined the amount of water added to the wet fabric when the skin cooling was equivalent to that of the dry fabric.Three groups of controlled skin cooling experiments were designed,with skin cooling set at 0.9℃(produced by contacting 18℃dry fabric or wet fabric with 2 mL water added),1.2℃(produced by contacting 13℃dry fabric or wet fabric with 12 mL water added)and 1.4℃(produced by contacting 8℃dry fabric or wet fabric with 16 mL water added),respectively.Sixteen subjects were invited to touch fabrics from each of the three different groups and report their subjective sensation scores for cold/warmth,dryness/wet ness and smooth ness/roughness.Results The Wilcoxon non-parametric test results were conducted on the two associated samples.It was found that the cold sensation of dry fabric at 18℃was significantly stronger than that of the wet fabric with 12 mL water(Z=-2.961,P=0.003).Additionally,the dry fabric at 13℃had a significantly stronger cold sensation compared to the wet fabric with 12 mL(Z=-2.456,P=0.014),but no significant difference existed between the dry fabric at 8℃and the wet fabric with 16 mL water(Z=-1.611,P=0.107).No significant difference existed in roughness sensation between the dry fabric at 18℃and the wet fabric with 2 mL water(Z=-1.459,P=0.145),while roughness of the dry fabric at 13℃was significantly lower than that of the wet fabric with 12 mL(Z=-2.645,P=0.008),and roughness of the dry fabric at 8℃was significantly lower than that of the wet fabric with 16 mL water(Z=-2.646,P=0.008)
