For this it is important and technical to adjust and control the degree of wetness of the paper. Especially in the case of treatment for damaged paper, the risks of historical artifact being damaged by water and the historically important information being lost increase. The rigid hydrogels of gellan gum, which is a natural polysachalide, can be effectively used to minimize such impact of water on paper. The present study evaluates the analytical study of residues and impact through accelerated ageing on paper samples after wet treatment by means of gellan gum application.\nThe residues of wet treatment by gel of gellan gum, which are potassium, calcium, and acetic acid ions, could be detected from Whatman paper. The pH of both Whatman paper and kozo paper treated with gel tends to be a little higher than that of paper with direct wet treatment. However, when the gel is washed with ultrapure water before gel wet treatment, the residue derived from gellan gum gel is dramatically reduced or not detected. Moreover, pH of the paper treated with washed gel shows almost the same value as paper treated with direct wet treatment as control. It is revealed that washing gel of gellan gum before using it for wet treatment of paper is effective because it does not leave residue derived from the gel. Some kinds of paper samples treated with non-washed gel are influenced in the value of pH, discoloration, and physical strength after hygrothermal ageing. However, when the paper samples are first treated with washed gel their physical characteristics change in the same way as the paper treated with direct water as a control. That is, washing gel is effective in avoiding the negative influence on paper after gel wet treatment.","subitem_description_type":"Abstract"}]},"item_10001_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.18953/00005731","subitem_identifier_reg_type":"JaLC"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"貴田, 啓子"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"堀, まなみ"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"大場, 詩野子"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"古田嶋, 智子"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"池田, 和彦"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"犬塚, 将英"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"早川, 典子"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Keiko, KIDA","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Manami, HORI","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Shinoko, OBA","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tomoko, KOTAJIMA","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kazuhiko, IKEDA","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Masahide, INUZUKA","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Noriko, HAYAKAWA","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-05-15"}],"displaytype":"detail","filename":"05710.pdf","filesize":[{"value":"1.4 MB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"05710.pdf","url":"https://tobunken.repo.nii.ac.jp/record/5756/files/05710.pdf"},"version_id":"8b35ff8e-697b-4b81-b6d6-773856f689c3"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ジェランガム","subitem_subject_scheme":"Other"},{"subitem_subject":"ゲル","subitem_subject_scheme":"Other"},{"subitem_subject":"紙","subitem_subject_scheme":"Other"},{"subitem_subject":"保存修復処置","subitem_subject_scheme":"Other"},{"subitem_subject":"湿り処置","subitem_subject_scheme":"Other"},{"subitem_subject":"gellan gum; gel; paper; conservation treatment; wet treatment","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"〔報告〕ジェランガムゲル処置による紙資料への影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"〔報告〕ジェランガムゲル処置による紙資料への影響"},{"subitem_title":"The Impact of W et Conservation Treatments on Paper Artworks with Gel of Gellan Gum","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"3","path":["874"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-05-15"},"publish_date":"2018-05-15","publish_status":"0","recid":"5756","relation_version_is_last":true,"title":["〔報告〕ジェランガムゲル処置による紙資料への影響"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-05-15T22:16:51.268096+00:00"}
