Abstract: Sulfopolyester thermoplastic resins provide advantages in papermaking processes and in paper products including paperboard. Improvements in wet strength and dry strength of paper products are achieved by addition of sulfopolyester thermoplastic resins and cationic strength additives during the paper making process. The use of sulfopolyester thermoplastic resins in paper products also significantly enhances the repulpability of the paper.
Abstract translation: 磺化聚酯热塑性树脂提供造纸工艺和造纸产品（包括纸板）的优势。 通过在造纸过程中加入磺基聚酯热塑性树脂和阳离子强度添加剂，可以实现纸张产品的湿强度和干强度的提高。 在纸制品中使用磺基聚酯热塑性树脂也显着提高了纸张的再浆化度。
