  The present invention is directed to a method for treating a material to impart wrinkle reduction and temporary crease resistance thereto, and improve feel. The method involves: applying to said material a solution of a treatment composition in an amount effective to impart temporary crease and stain resistance, said treatment composition contains a hydroxy urea or hydroxy amide compound; and allowing said treatment composition to dry at ambient temperature, wherein said hydroxy urea compound comprises one urea and at least one hydroxyl group and said hydroxy amide compound comprises at least one amide group and at least one hydroxyl group. The material treatment is useful in reducing wrinkles in clothing, improving the feel of fabrics, and increasing the moisture adsorbence and retention in natural and synthetic fabrics.

  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 β-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.

  一种使含有纤维素纤维的织物具有永久压榨性能的方法。该方法包括将（羟基烷基）脲和/或 β-羟基烷基酰胺交联剂的水溶液涂抹在纺织品上，并在足够的温度下加热纺织品足够的时间，使交联剂与纺织品发生反应，同时从纺织品中除去水分，从而赋予纺织品永久的压榨性能。交联剂不含甲醛。本发明的方法可使经其处理的纺织品具有永久压榨性能，并提高这些纺织品在今后洗涤时的耐磨性。与未经处理的纺织品相比，经过处理的纺织品褶皱明显减少。此外，经过处理的纺织品触感柔软，在洗涤后仍保持光滑。

  公开（公告）日：2003-02-27

  A composition which retards the spread of fire, protects assets at risk from fire damage and emits a material which aids in extinguishing the fire. The composition may be either in the form of a gel or a foam and may be used to protect any sort of object, such as personal property, real property or even humans, from fire. The gel form of the composition contains urea or a urea derivative that retains water and releases CO 2 upon heating. In addition, a rheology modifier containing carboxyl groups is also employed. The foam form of the composition contains the urea or urea derivative and the rheology modifier, along with a foam generator such as sodium bicarbonate and citric acid. A method of retarding fire comprises the coating of an item with the fire retardant such that the retardant protects the item from the fire and aids in extinguishing the fire by releasing carbon dioxide.
