Preparation, characterization of poly(acrylic acid)-g-feather protein-g-poly(methyl acrylate) and application in improving adhesion of protein to PLA fibers for sizing.

Unlabelled Image • Graft polymerization of feather protein with AA and PMA, respectively, for improving its adhesion to PLA fibers. • The PAA- g -FP- g -PMA can significantly improving the adhesion of feather protein to PLA fibers. • The PAA- g -FP- g -PMA is superior to FP- g -P(AA- co -MA) in improving the adhesion. • The PAA- g -FP- g -PMA used as an adhesive in warp sizing favors fulfilling the high-valued utilization of feather wastes.
