Sizing properties of this type of grafted starch are better than acid hydrolysis starch size and mixture size with little PVA size. It is poor than mixed size with large PVA size.
To reduce PVA dosage and enhance sizing quality of superfine high density variety, formula was designed, its main contents are modified starch, acrylic size and QQ-06 size mixture.
To strengthen the control of size dose and get exact sizing processing quickly, computer management program of size mixture formula and sizing processing was designed.
