The Study of Bleaching Silk Sanitary Materials

Abstract:

The silk Sanitary Materials in hydrogen peroxide bleaching process, various experimental factors affect on the raw materials’ whiteness and tension. And through the single factor experiments and orthogonal test research and analysis, the significant influencing order of the whiteness of silk fiber is: temperature, concentration of hydrogen peroxide, and bleaching time; the significant influencing order of breaking tension is: bleaching time, temperature, and concentration of hydrogen peroxide. The optimum experimental program is as follows: hydrogen peroxide concentration of 22.5g / L, bleaching temperature of 80 °C, bleaching time, 60min, PH value of 9, sodium silicate concentration of 11.25g / L.
