Wrinkle Resistant Properties of Dialdehyde Cotton

Abstract
The effect of periodic acid oxidation on the wrinkle resistance of cotton fabric has been investigated. In the range of oxidation where basic fabric properties are pre served the dry WRA increases with increasing oxidation. The change in wet WRA for these fabrics is negligible, suggesting that cross-links which are evident in the dry state are broken in the presence of water. An explanation involving hémiacetal and hemialdal formation is advanced.
