Polyvinyl Alcohol/Polyamide-epichlorohydrin 복합 지력증강제에 의한 종이 특성 향상

다국어 초록 (Multilingual 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. Asa result, PVA/PAE complex strengthening additive provided the distinctive gain dot in printed papers.
