ABSTRACT: The surface chemical analysis and bulk analysis were conducted for fibres regenerated from waste
garments and treated with iodine solution. The aim was to assess the fibre accessibility by the
iodine solution and ascertain the location of the reagent within the fibres. X-ray Photoelectron
Spectroscopy (XPS) analysis indicated that the fibres regenerated from indigo dyed waste denim
garments (ReCell-Denim) had a relatively high accessibility by the iodine solution compared to the
standard lyocell, ReCell-1 and ReCell-2 fibres. With the exception of ReCell-Denim, the standard
lyocell, ReCell-1 and ReCell-2 fibre’s iodine sorption values correlated well with the percentage
crystallinity. The high accessibility of the ReCell-Denim fibres was attributed to the presence of
the positively charged nitrogen from the indigo dyes that improved the substantivity of the fibres
to the iodine solution. The iodine sorption of the fibres is relatively higher in the bulk compared to
the fibre surface.
