    • An abrasive cloth which comprises an article in a sheet form having, in at least a part thereof, nanofibers comprising a thermoplastic polymer and having a number average single fiber fineness of 1×10−8 to 2×10−4 dtex wherein the sum of single fiber fineness percentages (which is defined in the specification) of a single fiber fineness of 1×10−8 to 2×10−4 dtex is the range of 60% or more, and exhibits a stress at 10% elongation in a longitudinal direction of 5 to 200 N/cm-width; and a method for preparing a nanofiber structure, which comprises providing a nanofiber dispersion having a dispersant and, dispersed therein, nanofibers comprising a thermoplastic polymer and having a number average diameter of 1 to 500 nm, attaching the dispersion to a support, and then removing said dispersant. The above abrasive cloth is excellent in texturing characteristics, and the above method allows the preparation of a nanofiber structure wherein nanofibers form a composite with the support.
    • 一种研磨布,其包括片状制品,其至少一部分具有包含热塑性聚合物的纳米纤维,并且具有1×10 -8至2×10 -6的平均单纤维细度, 4tex,其中单纤维细度为1×10 -8至2×10 -4分特的单纤维细度百分比(在说明书中定义)之和 为60%以上的范围,在长度方向的10%伸长率的应力为5〜200N / cm宽; 以及纳米纤维结构体的制造方法,其特征在于,提供具有分散剂的纳米纤维分散体,分散在其中的纳米纤维,所述纳米纤维包含热塑性聚合物,数均粒径为1〜500nm,将所述分散体附着到载体上, 所述分散剂。 上述研磨布的纹理特性优异,上述方法可以制备其中纳米纤维与载体形成复合材料的纳米纤维结构。
