对聚乙烯醇纤维改性改善成纸性能的研究

Modify PVA fibre to meliorate performance of paper

该文通过对聚乙烯醇(PVA)纤维改性改善成纸的性能作了研究。对针叶木浆以及瓦楞原纸浆中加入PVA纤维混合抄纸,对纸张物理性能的检测结果表明:加入PVA纤维后,纸样的撕裂度、裂断长及环压指数均有明显的提高。水溶性PVA纤维可作为纸张增强剂及花色纤维应用于纸浆纤维中,成纸有较好的强度,挺度及均匀性,可用于防伪、高档包装等用途。

It was studied that the performance of mixed pulp containing polyvinyl alcohol （PVA） fibers in this paper. The results showed that bearing strength, and break length and circle press strength have been significantly improved by the load of PVA fiber. Water-soluble PVA fiber can be used in pulp as a pulp enhancer and fashion, leading to the paper product of better strength, stiffness and uniformity. This kind of paper can be used to prevent oil, and to make high-grade packaging, etc.
