Abstract
This paper describes an analytical procedure for the determination of the sulphur distribution in wool fabrics that have been treated with bisulphite in setting processes. In such processes, disulphide bonds are broken and re-formed, and the proportion of re-formed disulphide bonds rises to a maximum as the pH rises from 1 to 2, and thereafter remains constant at higher pH values. A note on the niethods applicable to the analysis of wool sulphited with monoethanolamine sulphite is appended.
