INTRODUCTION
PVA-40 is an aqueous non-ionic emulsion of poly vinyl acetate. It provides excellent stability in weak acids, alkalis, and optical whitening agents.
APPLICATION
PVA-40 is generally accepted by all textile fibers and to achieve best results it should be applied by padding. If necessary, however the winch, jig, shallow vat or spraying apparatus may be used. The concentration required depends on the material. To give fabric a general finish 12-48 parts of resins are added in 1000 parts of water.
Key Applications:
White textile finishing
Dyed textile finishing
Cotton fabrics
Blended fabrics
