A method for imparting permanent press properties to a textile containing cellulose fibers. The method involves applying an aqueous solution of a (hydroxyalkyl)urea and/or a .beta.-hydroxyalkyl amide crosslinking agent to a textile, and heating the textile at a sufficient temperature for a sufficient time to react the crosslinking agent with the textile wherein water is removed from the textile, to impart permanent press properties to the textile. The crosslinking agent is free of formaldehyde. The method of the present invention provides permanent press properties to textiles treated therewith and increases the resistance of such textiles to future laundering abrasion. Such treated textiles display a significant reduction in wrinkles compared with nontreated textiles. Moreover, the treated textiles have a tactile sensation of feeling soft and retain their smoothness after laundering.
A method for imparting permanent press properties to a textile containing cellulose fibers wherein said method comprises applying an aqueous solution of a formaldehyde-free crosslinking agent to a textile, and heating the textile at a sufficient temperature for a sufficient time to react the crosslinking agent with the textile wherein water is removed from the textile, to impart permanent press properties to the textile, wherein the crosslinking agent is selected from the group consisting of (hydroxyalkyl)urea, .beta.-hydroxyalkylamide and combinations thereof, wherein the (hydroxyalkyl)urea has the structure ##STR15## wherein R.sup.1 is ##STR16## R.sup.2 is H or R.sup.5, R.sup.3 is H or R.sup.5, and R.sup.4 is H, R.sup.1, or R.sup.5, wherein
A method for imparting permanent press properties to a textile containing cellulose fibers wherein said method comprises adding either an aqueous solution of a formaldehyde-free crosslinking agent or a neat formaldehyde-free crosslinking agent to a laundering process comprising at least one textile, and heating the textile at a sufficient temperature for a sufficient time to react the crosslinking agent with the textile wherein water is removed from the textile, to impart permanent press properties to the textile, wherein the crosslinking agent is selected from the group consisting of (hydroxyalkyl)urea, .beta.-hydroxyalkylamide and combinations thereof, wherein the (hydroxyalkyl)urea has the structure ##STR23## wherein R.sup.1 is ##STR24## R.sup.2 is H or R.sup.5, R.sup.3 is H or R.sup.5, and R.sup.4 is H, R.sup.1, or R.sup.5, wherein
