The properties of the acrylic fabric， such as moisture regain， washability， breaking strength， air and moisture permeability， infrared spectrum and surface morphology， etc. before and after sericin finishing were studied. The results showed that sericin was treated on the surface of acrylic fabric through the effect of aziridine crosslinking agent. After sericin finishing， the moisture regain rate of the acrylic fabric increased from 1.76% to 2.92%～8.34%. After washing， the moisture regain rate maintained at about 2.03%. The radial breaking strength and stiffness of the modified acrylic fabric were 17.55% and 18.91% lower than those of the original fabric， while the zonal breaking strength and stiffness of the modified acrylic fabric were 18.54% and 12.95% lower than those of the original fabric.
