Abstract

''Durable press'' is a textile-finishing chemical treatment that imparts wrinkle resistance to fabrics by forming crosslinks between cellulose molecules. This treatment was applied to bleached softwood kraft handsheets in an effort to improve wet strength. The crosslinking agents used were maleic acid, citric acid, and 1,2,3,4-butanetetracarboxylic acid (BTCA). One catalyst (NaH2PO4) was particularly effective in promoting the esterification reaction between handsheets and the crosslinking agents. This reaction was confirmed by the weight gain of the handsheets, by Fourier-transform infrared spectroscopy, and by changes in sheet mechanical properties. Handsheet wet tensile strength improvedsignificantly (as high as 63 % of the dry strength) when BTCA was used as a crosslinking agent. Treatment with BTCA or citric acid had no detrimental effect on dry tensile strength, and handsheet brightness increased following treatment. However, the treatment severely reduced fold strength.
