One of the important uses of polyvinyl alcohol PVA1799 is to produce vinylon fiber. PVA1799 is also used in textile pulp and textile treatment agent to prevent fabric shrinkage and wrinkling. Polyvinyl alcohol will chemically crosslink with thermosetting resin, which can effectively avoid the reduction of the tear strength of fiber products due to surface treatment. The addition of PVA1799 in ceramic grinding can increase the fluidity and viscosity of clay and porcelain clay, facilitate filtration, help blank forming, reduce the breakage rate of blank transportation, and does not affect the shape and color of the finished product after sintering. In addition, it can also be used as a glaze binder, with less dosage and complete combustion at high temperature.
