Hydroxymethylated organic carbamates are reacted with water soluble alcohols to produce etherified hydroxymethylated carbamates which are used with an acid catalyst to treat cellulosic textiles for sufficient time and temperature to produce a durable press low formaldehyde release cellulosic textile. Carbamates from the group consisting of alkyl or alkoxyalkyl carbamates of less than six carbons can be used. Water soluble aliphatic monohydric and polyhydric alcohols of one to six carbons are also satisfactory. The hydroxymethylated carbamate is reacted with the alcohol at about 10.degree. C.-100.degree. C. for about 0.5 to 16 hours at a pH from about 1 to 6. Concentrations of acid catalyst range from 0.5 to 3.0% of the solution. Curing temperatures range from about 120.degree. C. to 160.degree. C. for about 0.5 to 10 minutes.
羟甲基化有机氨基甲酸酯与水溶性醇反应,产生醚化羟甲基化氨基甲酸酯,该醚化羟甲基化氨基甲酸酯与酸催化剂一起用于处理纤维素纤维织物,经过足够的时间和温度处理后,可以产生耐久的低甲醛释放的耐烫纤维素纤维织物。可以使用碳数小于六的烷基或烷氧基烷基氨基甲酸酯。一到六个碳的水溶性脂肪族单元和多元醇也是可行的。在pH值为1到6的条件下,将羟甲基化氨基甲酸酯与醇在大约10℃-100℃下反应约0.5到16小时。酸催化剂的浓度范围为溶液的0.5%到3.0%。固化温度范围为大约120℃到160℃,时间为0.5到10分钟。
