Notes:
Crosslinking of viscose rayon filament with dimethyl and methylvinyl diacetoxysilanes in benzene has been studied. The extent of crosslinking appears to depend on the nature of the reactant, material-to-reactant ratio, time, and temperature of the reaction. An increase in the breaking stress, initial modulus, and recovery properties was observed with increase in the crosslink density. Birefringence values as well as orientation index decrease in the treated samples. Thermal behavior of the crosslinked viscose was also studied by TGA and DTA, and it was found that IPDT (integral procedural decomposition temperature) and Dmax (maximum decomposition temperature) values of the crosslinked samples are higher than those of the untreated viscose.
