Title: Optimization of PVA Fiber Enhancement Paper Process with Dynamic Sheet Former Simulating Multilayer Inclined Wire Formers
Abstract: Dynamic Sheet Former(DSF) was adopted to simulate the multilayer inclined wire formers to implement papermaking for layers. The effects of soluble PVA fiber on paper strength properties in different positions of paper structure were analyzed, meanwhile, the effects of forming and drying process were discussed on the combination of PVA fiber and the machine direction and cross machine direction strength properties. The optimal efficiency can be acquired by optimizing the parameters of DSF, adding PVA 70 fiber(which could be dissolved completely at 70℃)with dosage of 0.8% to 1.0% in the Northern Bleached Softwood Kraft(NBSK), keeping the pneumatic control value at 0.2 MPa to 0.3 MPa and drying temperature at about 95℃ in this produce.
