The reactions between 1,2,3,4-Butanetetracarboxylic acid (BTCA) and cellulose is a solid heterogenous phase reaction and their reactivity is determined by the dispersion extent of BTCA in cellulose fibers. However, the crosslinking efficiency of BTCA to cellulose is not very high, especially when the curing temperature is below 160℃. In this study, we first analyzed the dispersion state of BTCA in pre-dried cotton fabrics under the different finishing concentrations and then discussed the effects of BTCA dispersion extent on the overall reactions from a kinetic perspective. The results indicated that BTCA molecules easily aggregated together under a high finishing concentration environment in cotton fabrics and thus difficultly diffused to the appropriate reaction sites to graft with cellulose, which reduced the kinetic constants of grafting reaction and made the grafting step become more important. On the other hand, the kinetic constants of grafting reaction were bigger than those of crosslinking reaction under a low finishing concentration condition, which demonstrated that the rate of whole reaction is determined by the rate of crosslinking reaction. Therefore, reduction of BTCA aggregation effect in cotton fabrics with the help of DMSO is beneficial to promote their overall reactions during the curing process and hence more satisfactory anti-wrinkle performance of treated cotton fabrics could be acquired.
