Tetraacetylethylenedianime (TAED) was used as an activator for the hydrogen peroxide (H2O2) bleaching of soybean protein/casein/polyvinyl alc. blend fibers (double protein fibers). The influences of dosage of H2O2, sodium silicate and sodium carbonate, temperature and time on the whiteness and yellowness of bleached fibers were investigated under the condition of n(H2O2):n(TAED) = 2:1. The dye uptake of Acid Blue 5R on bleached fibers was also measured through dyeing experiment It was found that the conventional hydrogen peroxide bleaching method was not fit for bleaching of double protein fibers. The hydrogen peroxide/TAED bleaching with 12 g/L of 30% H2O2, 5 g/L of sodium silicate, under 70°C for 60 min was fit for bleaching of double protein fibers, and the whiteness of bleached fibers was high and the dye uptake of bleached fibers was good. In the experiment, the researchers used many compounds, for example, N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide) (cas: 10543-57-4Related Products of 10543-57-4).
N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide) (cas: 10543-57-4) belongs to amides. Amides are pervasive in nature and technology. Proteins and important plastics like Nylons, Aramid, Twaron, and Kevlar are polymers whose units are connected by amide groups (polyamides); these linkages are easily formed, confer structural rigidity, and resist hydrolysis. As a result of interactions such as these, the water solubility of amides is greater than that of corresponding hydrocarbons. These hydrogen bonds are also have an important role in the secondary structure of proteins.Related Products of 10543-57-4
