Claims (4)
- ミクロフィブリルセルロースと粉体と紙力増強剤との凝集体が散点状に分布して模様を形成している模様紙の製造方法であって、
ミクロフィブリルセルロース、粉体、紙力増強剤及び親水性繊維を含む原料スラリーを槽内に貯留し、該原料スラリー中の固形分を抄紙網で抄き上げて該抄紙網の表面に湿紙を形成する湿紙形成工程を有し、
前記湿紙形成工程において前記原料スラリーを前記槽内に滞留させ、
前記原料スラリーの前記槽内での滞留は、該原料スラリーを該槽からオーバーフローさせないことでなされる、模様紙の製造方法。 - 前記紙力増強剤は、カチオン性及びアニオン性の2種類を含む請求項1に記載の模様紙の製造方法。
- 前記原料スラリーは、ミクロフィブリルセルロース、粉体及び親水性繊維を含む原料スラリー前駆体に、前記カチオン性紙力増強剤及び前記アニオン性紙力増強剤をこの順で添加することにより調製される請求項2に記載の模様紙の製造方法。
- ミクロフィブリルセルロースと粉体と紙力増強剤との凝集体が散点状に分布して模様を形成している模様紙の製造方法であって、
ミクロフィブリルセルロース、粉体、紙力増強剤及び親水性繊維を含む原料スラリーを槽内に貯留し、該原料スラリー中の固形分を抄紙網で抄き上げて該抄紙網の表面に湿紙を形成する湿紙形成工程を有し、
前記湿紙形成工程において前記抄紙網を透過した前記原料スラリーである排水スラリーを前記槽外に排出し、該排水スラリーに該排水スラリーとは反対の電荷を有する凝集剤を添加して凝集剤添加スラリーを得、該凝集剤添加スラリーを該原料スラリーと共に該槽内に導入して前記湿紙の形成に使用する、模様紙の製造方法。
