Application Of Formaldehyde-free Finishes To Man-made Fibre Fabrics And Performance Evaluation Of The Finished Fabric

摘要

The present study was carried out to develop low formaldehyde and formaldehyde free finishing formulations for cellulosic fabrics. Low formaldehyde formulations were developed such that the formaldehyde released was within the prescribed limits for clothing worn next to the skin. DMDHEU-based formulations are suitable for this purpose and can be used along with acrylic polymers and other finishing formulations. The results obtained with DMDHEU-based formulations are satisfactory in terms of crease recovery angle, whiteness retention, tensile strength and formaldehyde released. The formaldehyde released values of Recipe 2, from the unwashed substrate, are within the prescribed limits for outerwear clothing.rnThere is only a small decrease in the whiteness value of the Recipe 2 treated fabrics as compared to the untreated substrate. Tensile strength values are not greatly reduced as compared to the untreated substrate.
