| 摘 要： | FTIR-ATR technique with second-order derivative measurement was used for assessing the amount of oxidation products of cystine present on the plasma-treated wool fabric surface. In this paper, three non-polymerising gases namely oxygen, nitrogen and 25% hydrogen/75% nitrogen gas mixture were used for the plasma treatment of wool fabric. The oxidation products of cystine studied included S-sulphonate, cysteic acid, cystine monoxide and cystine dioxide. The variations of the amount of these products as a function of treatment time were studied. Experimental results showed that the oxygen plasma could produce a large amount of oxidation products of cystine on the wool fabric surface followed by nitrogen plasma and gas mixture plasma.
