Crosslinking of Sulfonated Cotton Cellulose Part I: Crosslinking and Physical Properties of DMDHEU-Treated Fabrics

摘要

Various degrees of sulfonated and unsulfonated cotton fabric samples are treated with DMDHEU in the presence of a mixed catalyst under mild curing temperatures. At a given DMDHEU concentration in the bath, the nitrogen contents of the finished fabrics increase with increasing degrees of sulfonation, while the formaldehyde content de- creases. △WCRA values increase with increasing sulfonation at the same values of △DCRA and △TSR. For a given value of CL/AGU, the △WCRA and CL length values increase as the sulfonation degree of the fabrics increases.
