Abstract
A method for imparting wrinkle free properties to cotton or cotton blend fabrics. These wrinkle free properties are achieved through the use of a combination of a DMDHEU based reactant at high levels with a catalyst at a low level.
Claims16
A method for imparting wrinkle free properties to cotton or cotton blend fabrics comprising the steps of:
- (a) selecting an all cotton or cotton blend fabric having warp and fill strengths that provides balanced finished strengths in both the warp and fill direction;
- (b) contacting the cotton or cotton blend fabric with a reactant bath comprising a combination of:
- (i) an amount of DMDHEU based reactant sufficient to provide a total formaldehyde content to the fabric of from about 0.7% to 1.5%,
- (ii) a MgCl.sub.2.6H.sub.2 O catalyst in an active amount of from about 1.0% to 15% based on the active weight of the DMDHEU based reactant,
- (c) heating the cotton or cotton blend fabric under conditions wherein the DMDHEU based reactant is cured to 70% to 95%.

A wrinkle free cotton or cotton blend fabric made according to a process comprising the steps of:
- (a) selecting an all cotton or cotton blend fabric having warp and fill strengths that provides balanced finished strengths in both the warp and fill direction;
- (b) contacting the cotton or cotton blend fabric with a reactant bath comprising a combination of:
- (i) an amount of DMDHEU based reactant sufficient to provide a total formaldehyde content to the fabric of from about 0.7% to 1.5%,
- (ii) a MgCl.sub.2.6H.sub.2 O catalyst in an active amount of from about 3% to about 7% based on the active weight of the DMDHEU based reactant,
- (c) heating the cotton or cotton blend fabric under conditions wherein the DMDHEU based reactant is cured to 70% to 95%.
