Description

本発明において、水分散重合物と顔料の混合物の付着量は、不織布全質量の２０〜６０質量％が好ましく、より好ましくは２５〜５５質量％であり、さらに好ましくは３０〜５０質量％である。付着量が２０質量％よりも低いと、インキ着肉性においても十分な印刷濃度が得られないことがある。一方、６０質量％を超えると、水分散重合物の付与により、不織布独特の柔らかな風合いが損なわれることがある。 In the present invention, the adhesion amount of the mixture of the water-dispersed polymer and the pigment is preferably 20 to 60% by mass, more preferably 25 to 55% by mass, and further preferably 30 to 50% by mass of the total mass of the nonwoven fabric. . When the adhesion amount is lower than 20% by mass, a sufficient printing density may not be obtained even in the ink deposition property. On the other hand, when it exceeds 60 mass%, the soft texture peculiar to a nonwoven fabric may be impaired by provision of a water-dispersed polymer.

本発明の展示用不織布は、該不織布を抄紙の流れ方向に直角に折り、折った背の５ｃｍの区間を１０倍のルーペで観察した際に観察できる立ち上がった毛羽本数が、表裏ともに５〜６５本であり、より好ましくは１０〜６０本であり、さらに好ましくは１５〜５５本である。毛羽本数が５本よりも少ないと、パネルへの貼り付き性が悪くなる。一方、６５本を超えると、表面の平滑性が失われ、十分な印刷濃度が得られず、印刷抜けなどが起こる。なお、毛羽本数の測定は表裏で区別し、サンプル毎に表裏それぞれ５個以上データをとり、最大と最小を除いて平均した本数を、ここで言う「毛羽本数」とする。また、ここで言う「表」とは、抄紙の際の湿紙乾燥時に接触型ドライヤーに接していた面、もしくは、非接触型の乾燥機を用いた場合は熱量が多くかかった側の面を言う。
The nonwoven fabric for display of the present invention has a number of fluffs that can be observed when the nonwoven fabric is folded at a right angle to the paper flow direction and the 5 cm section of the folded back is observed with a 10-fold loupe. It is a book, More preferably, it is 10-60, More preferably, it is 15-55. When the number of fluff is less than 5, the sticking property to the panel is deteriorated. On the other hand, when it exceeds 65 present, the surface smoothness is lost, no sufficient print density is obtained, white dots like occurs. In addition, the measurement of the number of fluff is distinguished on the front and back sides, and 5 or more data are obtained for each front and back for each sample, and the average number excluding the maximum and minimum is referred to as the “number of fluff”. In addition, the “table” here refers to the surface that was in contact with the contact dryer during wet paper drying during papermaking, or the surface on the side where a large amount of heat was applied when a non-contact dryer was used. To tell.
