吸濕排汗產品大多數被應用於太陽光中紫外線強烈照射之環境下,目前除對其外觀顏色與的衰變有相關法規可進行洗滌測試外,在針對該類產品於紫外線環境下的功能性耐久強度與衰退程度的檢驗卻尚未有人進行。本試驗利用耐候紫外光試驗機 (UV2000)對樣本進行模擬日照能量加速測試,同時以洗滌測試之結果作為對照組,針對後續因應功能性中的水份管理與材質變化相關功能進行測試,對紫外線影響下的吸濕排汗產品之水份管理能力之探討。實驗結果顯示,以聚對苯二甲酸乙二醇酯 (polythylene terephthalate, PET)與聚醯胺纖維 (polyamide, NYLON 66)為樣本,進行洗滌測試與紫外線照射試驗後,紫外線影響織品樣本的水份擴散功能較一般水洗較為明顯,當水份擴散功能被降低時,很可能會影響接下來的水分蒸散之時間,並使排除水份的功能受到減弱,從而降低了吸濕排汗產品之功能。
Most products with wicking properties of moisture diffusion are used in strong sunlight with ultraviolet irradiation of the environment. The properties of color and appearance decay by washing are determined with the stander level but not ultraviolet at present. This study provides the data of moisture management including PET and NYLON 66 that treated with wash and ultraviolet respectively. The data shows results of absorbency, wicking and drying test that revealed, compared with washing, the wicking function decrease of PET and NYLON 66 by ultraviolet. That could affect the moisture management of the products with wicking properties of moisture diffusion.
