shows the possible decomposition pathways of CA inthe presence of SHP. Previous NMR experiments had revealedthat 2MSA was the major product (Yao et al., 2013) and sev-eral other unsaturated PCAs were also present. CA and all itsdecomposition products were able to form ester linkages withcellulose and contribute to the change in its macroscopic prop-erties. LC experiments were carried out to identify and quantifyPCAs in the CA/SHP-cellulose crosslinking system. To preparethe analytes, treated fabrics were subjected to Na2CO3washesand NaOH saponifications subsequently as described in Sec-tion 2.3. Based on the WRA measurements of the washed andsaponified fabrics (Table A.5), the washes only removed theunfixed PCAs, while the saponification treatment were suffi-cient in hydrolyzing all ester linkages. PCAs fixed and unfixedto cellulose could be analyzed separately by subjecting thesaponification and wash liquors to LC–MS and HPLC. A typicalchromatogram is shown in Fig. A.2 and the results are summa-rized in Table 1. The elution conditions used were slightly differentfor LC–MS and HPLC experiments, resulting in different retentiontimes.
