Abstract
The effect of polyvinyl alcohol/polyamide-epichlorohydrin (PVA/PAE) complex strengthening additive on dry and wet strength and surface properties of paper was investigated. The enhancements of dry and wet strength and dimensional stability were found when PVA/PAE was applied as a complex strengthening additive compared with the cases of applying individual PVA or PAE. This was understood as physical crosslinking between PVA and PAE in the PVA/PAE complex strength additive. This complex strengthening additive also lowered surface roughness and increased sizing. As a result, PVA/PAE complex strengthening additive provided the distinctive gain dot in printed papers.

Polyvinyl alcohol/polyamide-epichlorohydrin(PVA/PAE) 복합 지력증강제 처리에 따른 종이의 건조 및 습윤인장강도와 표면특성 변화를 살펴보았다. PVA/PAE 복합 지력증강제를 사용하는 경우, PVA와 PAE를 각각 첨가제로 사용하는 것에 비하여 건조 및 습윤 인장강도 증가와 함께 치수안정성이 우수해 짐을 알 수 있었으며 이는 PVA와 PAE의 물리적인 가교에 의한 결과로 해석할 수 있었다. PVA/PAE의 복합화는 PAE 지력증강제 처리에 의하여 발생하는 종이의 표면 거칠기의 증가를 최소화하며 동시에 사이징도 증가시켜 종이 인쇄 시 색농도 증가에 기여함을 알 수 있다.

Keywords: polyamide-epichlorohydrin; polyvinyl alcohol; strengthening additive for paper; dry and wet strength; degree of sizing; surface roughness in paper.
