Formaldehyde is a highly reactive chemical and an irritant to the eyes and throat. the amountof formaldehyde released from wash and wear finishing fabrics was significantly reduced because ofamide group development and the modification of the N-hydroxymethyl group. Based on the studyof the optimum finishing technology condition, the fabrics finished by the low-formaldehyde a-gents can reach the standards for ECO fabrics. At present the formaldehyde-free agent, 1, 2, 3, 4-butane-tetracarboxylic acid (BTCA), has been significantly developed in applied technology, whichmade a sood condition for developing saferand more healthful finishing products. But there still re-main some problems which need to be studied in the future- So the low-formaldehyde agents fortextile finishing are still the main focus at present.
