本論文以幾丁聚醣對化纖織物之整理加工(pad-dry-curing)，檢討改良其抗菌性與吸濕性複合機能的最適化加工條件。本研究中首先以幾丁質(chitin)為原材料，以濃鹼液NaOH(50%)於高溫下加熱處理，不同時間(1hr∼8hrs)下，可得到去乙醯度75∼95%之幾丁聚醣(chitosan)。進而探討不同去乙醯度之幾丁聚醣(chitosan)，在不同濃度範圍(0.02--.0.10%)下，對加工織物抗菌性與吸濕性之影響。
自製幾丁聚醣(chitosan)的性質，測定包括:（1）利用傅立葉轉換紅外線光譜儀分析(FTIR)：測定薄膜胺基含量（2）利用ESCA電子光譜，分析薄膜表面的碳「C」、氮「N」、氧「O」含量。（3）利用元素分析，測試碳「C」、氮「N」、氧「O」、氫「H」含量。（4）利用膠體滴定法(colloid titration)測定幾丁聚醣的去乙醯度( degree of deacetylation)。（5）利用黏度與分子量的關係【Mark-Houwink equation】求得平均分子量。
在織物加工應用方面，上述所得之幾丁聚醣(chitosan)，係以壓吸方式進行加工(pad-dry-curing)，結果顯示織物之抗菌性隨幾丁聚醣濃度增加而增大，並隨去乙醯度增加而增強。紡織品之吸濕性，亦隨幾丁聚醣濃度增加而增加。但隨去乙醯度增加而降低。
綜合以上結果，當幾丁聚醣之去乙醯度80%，分子量45kDa以下時，可得到一個同時兼具抗菌、吸濕之複合機能加工織物。

This study is to investigate the effect of chitosan on the antimicrobial activity and water absorbency for the textiles finishing application.
Chitin was treated with NaOH 50%(wt) at 100℃ for different intervals (1hr—8hrs) to deacetylate into chitosan. The resulting chitosan was
characterized including FTIR spectroscopy, Electron Spectroscopy for Chemical Analysis (ESCA),Elemental analysis (EA),colloid titration test to evaluate the degree of deacetylation and viscosity average molecular weight (MV) measurement.Moreover, the resulting chitosan was then finished onto polyester and polyamide fabrics via the pad-dry-curing process.
The results show that the deacetylation increased,while the MV decreased with the alkali treating time.the deacetylation was confirmed by the FTIR, EA and ESCA results .By finishing with chitosan ,PET and Nylon fabrics exhibited antimicrobial activity against Staphylococcus aureus and the water absorbency was greatly improved. Furthermore ,to test the washing durability of the fabrics treated with the chitosan . The results indicated that the antimicrobial activity was disappeared after five washing cycles.
