Description
図1は、実施形態に係る抄紙シート1を示す図である。抄紙シート1は、セルロースエステル短繊維と、パルプ繊維と、バインダとを含んでいる。抄紙シート1は、一例として、抄紙機10(図2参照)により帯状に製造され、ロール状に巻回されている。図1では、抄紙シート1に形成されるクレープ1aを模式的に大きく図示している。ロール状の抄紙シート1は、例えば、後の工程で必要な幅にスリット加工され、連続的に繰り出されて、加工品の製造に供される。
R=(V1−V2)/V1×100
但し、V1は、抄紙シート1の製造時における抄紙機10の加熱ロール26の周速度であり、V2は、抄紙シート1の製造時における抄紙機10の巻取リール28の周速度である(図2参照)。
図2は、実施形態に係る抄紙機10の模式図である。抄紙機10は、一例として長網抄紙機である。抄紙機10は、組成物調整パート11、ワイヤーパート12、プレスパート13、ドライヤーパート14、及び巻取リール28を備えている。組成物調整パート11、ワイヤーパート12、プレスパート13、及びドライヤーパート14の各々は、公知の構成を有する。なお、以下に言及する上流側と下流側とは、抄紙機10における組成物、シート体30、及び抄紙シート1の搬送方向の上流側と下流側とをそれぞれ指す。
図3は、実施形態に係る抄紙シート1の製造工程を示す製造工程図である。図3に示すように、実施形態に係る抄紙シート1の製造方法では、原料調整工程S1、ワイヤー工程S2、プレス工程S3、ドライ工程S4、クレープ形成工程S5、巻取り工程S6、及びスリッター工程S7を順次行う。ここでは、抄紙機10を用いて工程S1〜S6を順次行う。
[試験方法]
セルロースアセテート短繊維及び針葉樹クラフトパルプ繊維及びカルボキシメチルセルロースナトリウム塩(エーテル化度0.86、株式会社ダイセル製CMC1220)を用いて抄紙シートを製造した。その重量割合は、セルロースアセテート短繊維、針葉樹クラフトパルプ繊維、及びカルボキシメチルセルロースナトリウム塩の順に、49.5:49.5:1.0に設定した。
表1、2及び図4に示すように、比較例1、2及び実施例1〜17の抄紙シートの引張強度と破断伸度とは、略反比例の関係にあり、クレープ率Rが高いほど破断伸度が高くなることが確認された。
