Abstract:	本研究中以不同的處理方式來處理三種纖維素纖維，以透濕試驗機測試這三種纖維在經過鹼液與酵素處理前後在各種不同相對濕度下吸濕與脫濕的變化。在研究中發現，在不同的處理過後，隨者鹼濃度的改變，會影響吸濕性的變化，纖維素纖維在經過鹼處理過後會破壞纖維的結晶區且讓纖維產生膨潤現象，而在經過酵素處理後的纖維，纖維的表面會被水解。經由透濕試驗機可以得知在相對濕度95%時Lyocell纖維在未處理前，回潮率為17.5%，而在經過濃度10%的鹼處理後，回潮率增加到23.9%，酵素處理後的回潮率增加到21.1%，先酵素處理後再做濃度10%的鹼處理後的回潮率為21.5%,先濃度10%的鹼處理復再做酵素處理的回潮率為20.8%。在處理過後的纖維，部份的回潮率都有明顯的增加。 In this research, we deal with three kinds of cellulose fibers with different treatments, and examine these fibers' change of moisture sorption and desorption under all kinds of relative humidity before and after dealing by using the completely wet testing machine. We discovered in the research that after different treatments the change of the moisture sorption was affected by the change of the thickness of NaOH. That's because cellulose fibers will destroy the fibers' crystalline and made it to have swelling phenomenon after the NaOH's treatment. The fibers which were treated with zyme would be hydrolyzed on the facial part. For example, by using the completely wet testing machine we could discover that Lyocell with 95% of relative humidity before any treatment, the moisture regain is 17.5%. And after the treatment of a thickness of 10% NaOH, the moisture regain increased to 23.9%. The moisture regain increased to 21.1% after the zyme treatment. The moisture regain which use zyme treatment first and then the thickness of 10% NaOH treatment is 21.5%, and with the thickness of 10% NaOH treatment first and then the zyme treatment is 20.8%. We could discover in the experiment that most of the moisture regain had an apparent increase with treated fibers.
