| description | The present invention addresses the problem of providing a sheet which has excellent transparency, while being suppressed in curling. The present invention relates to a dispersion liquid which contains a fibrous cellulose that has a fiber width of 1,000 nm or less, while having an ionic substituent, wherein: the content of the fibrous cellulose is 3.0% by mass or more relative to the total mass of the dispersion liquid; and the TI value of the dispersion liquid as calculated under the conditions (a) described below is from 1 to 80,000. Conditions (a): The viscosity (η1) of the dispersion liquid at a shear rate of 1 sec-1 and the viscosity (η2) of the dispersion liquid at a shear rate of 1,000 sec-1 are measured with use of a rheometer, and the TI value is calculated by the formula described below. TI value = η1/η2
La présente invention aborde le problème de la fourniture d'une feuille qui a une excellente transparence, tout en étant supprimée lors du roulage. La présente invention concerne un liquide de dispersion qui contient une cellulose fibreuse qui a une largeur de fibre de 1 000 nm ou moins, tout en ayant un substituant ionique, la teneur de la cellulose fibreuse étant de 3,0 % en masse ou plus par rapport à la masse totale du liquide de dispersion ; et la valeur TI du liquide de dispersion telle que calculée dans les conditions (a) décrites ci-dessous est de 1 à 80 000. Condition (a) : la viscosité (η1) du liquide de dispersion à une vitesse de cisaillement de 1 sec-1 et la viscosité (η2) du liquide de dispersion à une vitesse de cisaillement de 1 000 sec-1 sont mesurées à l'aide d'un rhéomètre, et la valeur TI est calculée par la formule décrite ci-dessous. Valeur TI = η1/η2
本発明は、透明性に優れ、かつカールが抑制されたシートを提供することを課題とする。本発明は、繊維幅が１０００ｎｍ以下であり、イオン性置換基を有する繊維状セルロースを含む分散液であって、繊維状セルロースの含有量が分散液の全質量に対して３．０質量％以上であり、下記条件（ａ）により算出した前記分散液のＴＩ値が１以上８００００以下である、分散液に関する。 条件（ａ）：レオメーターを用い、前記分散液のせん断速度１ｓｅｃ－１の条件における粘度（η１）と、前記分散液のせん断速度１０００ｓｅｃ－１の条件における粘度（η２）を測定し、下記式によりＴＩ値を算出する。 ＴＩ値＝η１／η２ |
