    • A nonwoven sheet contains a substrate layer formed from a fiber aggregate nonwoven structural member; the fiber aggregate nonwoven structural member containing a thermal adhesive fiber; the thermal adhesive fibers are melt-bonded to fix the fibers of the member. The average thickness of the substrate layer is adjusted to not less than 0.2 mm to less than 1 mm, and the thermal adhesive fibers are substantially uniformly melt-bonded in a surface direction of the substrate layer. The sheet may have a surface layer over at least one side of the substrate layer, the surface layer may contain a fiber aggregate nonwoven structural member having an apparent density higher than the apparent density of the substrate layer. The surface layer may comprise a layer formed by heat-pressing or may be formed from a meltblown nonwoven fabric. The thermal adhesive fiber may be substantially uniformly melt-bonded in a thickness direction of the substrate layer. The thermal adhesive fiber may contain an ethylene-vinyl alcohol-series copolymer; the copolymer may form a continuous area of a surface of the fiber. The sheet has an improved flexural rigidity, less deformation under a load, and an excellent formability, in spite of a small thickness thereof.
    • 非织造片包含由纤维聚集体非织造结构构件形成的基底层; 所述纤维聚集体非织造结构构件包含热粘合纤维; 热粘合纤维被熔融粘合以固定构件的纤维。 基板层的平均厚度被调整为不小于0.2mm至小于1mm,并且热粘合纤维基本上在基材层的表面方向上熔融粘合。 片材可以在衬底层的至少一侧上具有表面层,表面层可以包含表观密度高于衬底层的表观密度的纤维聚集体非织造结构构件。 表面层可以包括通过热压形成的层,或者可以由熔喷非织造织物形成。 热粘合纤维可以在基材层的厚度方向上基本均匀熔融粘合。 热粘合纤维可以含有乙烯 - 乙烯醇系共聚物; 共聚物可以形成纤维表面的连续区域。 尽管薄片的厚度小,但是片材具有改善的抗弯刚度,较少的载荷下的变形和优异的成形性。

    • A process for the production of a fabric made of extrafine animal fibres which are not industrially weaveable, comprising the following sequence of steps:
      a) spinning of blended yarns (1) made of extrafine animal fibres, specifically cashmere fibres and silk fibres;
      b) doubling of each of said blended yarns (1) with a corresponding yarn made of synthetic fibres (2), preferably having an equivalent count, soluble in a slightly acidic liquid solution at a high temperature; the doubling is preferably carried out with a torsion S in a direction opposite to the torsion Z of the blended yarns (1);
      c) weaving of the doubled yarns (3);
      d) dissolving said synthetic fibre yarns (2) by means of a slightly acidic liquid solution at a high temperature.
      An extremely soft fabric consisting only of extrafine blended yarns (1) made of animal fibres and silk fibres, which are not industrially weaveable per se, is thereby obtained.
    • 一种用于生产织物制成超细动物纤维,其在工业上weaveable,包括以下步骤顺序的步骤:a)制成极细动物纤维的混纺纱(1)的纺丝,特别是绒纤维和丝纤维; b)中每个所述的倍增混纺纱(1)用由合成纤维制成相应的(2),优选具有在相当于计数,易溶于在高温下略微酸性液体溶液的纱; 倍增优选用捻小号进行。在一个方向相反的混纺纱(1)的扭转Z者除外; c)该加倍纱线的编织(3); D)溶解合成纤维纱线(2)通过在高温下略微酸性液体溶液的装置,把所述。 极其柔软织物仅由由动物纤维和丝纤维的极细混纺纱(1),这是工业上不weaveable本身,由此获得。
