Synthesis and adhesion-to-wool of sulfosuccinylated starch

In order to improve the usability of starch,a series of sulfosuccinylated starch( SSS) with different degrees of substitution( DS) was prepared for surveying the effects of starch sulfosuccination and paste temperature on the adhesion to wool fibers in term of bonding strength. The results show that starch sulfosuccination can obviously improve the adhesion to wool fibers. The influences of starch sulfosuccination level and paste temperature show significant influence on the adhesion. At the same temperature,the adhesion increases gradually with the increase in DS. And at the same DS value,the adhesion decreases as the paste temperature reduces,but a reduced trend of adhesion is displayed significantly compared with acid-thinned starch. The adhesion of starch to wool fibers can be significantly improved by using SSS with the DS of 0. 036 in the temperature range of 50-65 ℃.
