Influences of configuration and molecular weight of hemicelluloses on their paper-strengthening effects

► The structure of hemicelluloses influences their paper-strengthening effects. ► Hemicelluloses mixed with paste starch as surface sizing agent showed obvious effect. ► The effects of APMP hemicellulose differ not widely from wood hemicellulose. ► Hemicellulose can be used instead of starch partly. ► Use of HYP-waste-liquor hemicellulose responds to economic, energy, food concerns.
