一家位于北欧的年产3万t的卫生纸工厂在其双网纸机上为德国市场生产纸巾。抄造使用原生纤维和回收纤维的混合浆料,为了达到所要求的湿强度,抄造时加入大量的湿强树脂。多年来,该工艺已被全面优化,并使用了一种高阴离子型物质来提高湿强树脂的留着和改善纸 A tissue paper mill with an annual output of 30,000 t in northern Europe produces paper towels for the German market on its double-web machine. Papermaking uses a mixture of virgin fibers and recycled fibers. To achieve the required wet strength, a large amount of wet strength resin is added during papermaking. Over the years, the process has been fully optimized and uses a high-anionic material to enhance wet-strength resin retention and improve paper
