Abstract

The glyoxal has been used as formaldehyde free DP(durable press) agents in wrinkle free treatment for cotton fabrics. However, the yellowing problem is a disadvantage of DP finishing process for cotton fabrics with glyoxal. In order to improve the whiteness, it was investigated that the effect of coreactant and treatment method with various whitening additives such as STB(sodium tetraborate, $Na_2B_4O_7$), SPB(sodium perborate, $NaBO_3$), SC(sodium chlorite, $NaClO_2$) and SPC(sodium percarbonate, $Na_2CO_3{\cdot}1.5$ $H_2O_2$). The increasing the concentration of whitening additives(STB, SPB, SC and SPC), the whiteness and the strength retention ratio of cotton fabrics were increased but the wrinkle recovery angles were decreased in one bath method. It was not suitable to improve whiteness because the whiteness value is about 60. In the case of SC used two bath method, the whiteness is near 70, which is similar to untreated fabrics, without decreasing of WRA and strength.
