Abstract (en)
It is an object of the present invention to provide a high-bulk cellulose fiber-containing sheet, wherein the water-retaining ability of the cellulose fibers is sufficiently high, and the water-absorbing rate is large. The present invention relates to a composition comprising cellulose fibers having phosphoric acid groups or phosphoric acid group-derived substituents, wherein, in at least a part of the cellulose fibers, the phosphoric acid groups or the phosphoric acid group-derived substituents are crosslinked, the number of crosslinking points in the cellulose fibers, which is calculated according to the following Equation (1), is 0.20 mmol/g or more, and the water content is 50% by mass or less, with respect to the total mass of the composition:
