The amorphous disulfide-crosslinked polycaprolactam fiber, a wool model fiber, was pretreated in 0.08 MKCN in a relaxed state for various periods at temperatures between 30 and 50°C, then, stretched to 100% in the same medium and the continuous stress relaxation, due to the cleavage of disulfide crosslinks, was measured. From the initial and the remanent stress values, the amounts of disulfide and monosulfide crosslinks and the intermediates at the end of the pretreatment in 0.08M KCN were estimated.
