(EN) ADHESIVE FOR CREPE AND METHOD FOR MANUFACTURING CREPE PAPER
(FR) ADHÉSIF POUR CRÊPE ET PROCÉDÉ DE FABRICATION DE PAPIER DE CRÊPE
(JA) クレープ用接着剤及びクレープ紙の製造方法
要約
(EN)
The present invention addresses the problem of providing an adhesive for crepe that has outstanding adhesiveness between fiber webs when paper is being manufactured and with which, even if the amount of coating film elution by water infiltrating from wet paper and the like is small, the paper can be easily separated, favorable crepe can be formed, and the amount of abrasion of a doctor blade is small because the film formed is soft. Provided is an adhesive for crepe that comprises a polyamidopolyamine/epihalohydrin resin (A) and/or a polyamidopolyamine polyurea/epihalohydrin resin (B) and a softener (C), and is characterized by fulfilling all designated conditions.
(FR)
La présente invention concerne le problème consistant à fournir un adhésif pour crêpe ayant une capacité d'adhésion exceptionnelle entre les nappes de fibres lors de la fabrication du papier et avec lequel, même si la quantité d'élution du film de revêtement par de l'eau d'infiltration, provenant du papier humide et similaires, est faible, le papier peut être facilement séparé, un crêpe de bonne qualité peut être formé, et la quantité d'abrasion d'une lame de racloir est faible parce que le film formé est doux. Selon l'invention, l'adhésif pour crêpe comprend une résine de polyamidopolyamine/épihaolhydrine (A) et/ou une résine de polyamidopolyamine polyurée/épihalohydrine (B) et un adoucissant (C), et est caractérisé en ce qu'il satisfait à toutes les conditions mentionnées.
(JA)
 本発明は、紙を製造する際に繊維ウェブ間の接着性に優れ、湿紙などから持ち込まれる水分によるコーティング皮膜の溶出が少ないにもかかわらず紙が離解しやすく、良好なクレープの形成を可能とし、形成する皮膜がやわらかいためドクターブレードの摩耗の少ないクレープ用接着剤を提供することを課題とする。 ポリアミドポリアミン・エピハロヒドリン樹脂(A)および/またはポリアミドポリアミンポリ尿素・エピハロヒドリン樹脂(B)並びに軟化剤(C)を含有するクレープ用接着剤であって、特定の条件を全て満たすことを特徴とするクレープ用接着剤。
