    • The invention concerns a method for preparing cellulose microfilaments, consisting in: preparing a cellulose solution (C); extruding the latter through the hole(s) of a die (1); said die (1) hole(s) having such diameter that in the absence of drawing the said solution (C) passing through said die hole(s) produces filaments with a yarn count T0 not more than 2.5 dtex; hydraulically drawing, at the outlet of said hole(s), said extruded solution; said drawing being carried out with a liquid (F) capable of regenerating or precipitating, at least partially, said cellulose. The invention also concerns the preparation of microfibres from the resulting microfilaments. The invention enables the preparation of highly hydrophilic cellulose microfilaments and microfibres (with yarn count less than 0.7 dtex) and also, directly and continuously, microfilament and microfibre nonwoven fabrics.
    • 本发明涉及一种制备纤维素微丝的方法,包括:制备纤维素溶液(C); 将其通过模具(1)的孔挤出; 所述模具(1)具有这样的直径,使得在没有拉伸通过所述模孔的溶液(C)的情况下,产生具有不大于2.5dtex的纱线数T的长丝; 在所述孔的出口处液压拉伸所述挤出溶液; 所述拉伸是用能够至少部分地再生或沉淀所述纤维素的液体(F)进行的。 本发明还涉及从所得微丝制备微纤维。 本发明能够制备高度亲水的纤维素微丝和微纤维(纱线计数小于0.7dtex),并且可以直接连续地制备微丝和微纤维非织造织物。

    • A process and material therefrom is described where a material comprised of a continuous orientable polymer matrix with one or more discontinuous or continuous second phases is stretched in the solid state using more than one device to apply force to the unoriented material to form a material that consists of a continuous oriented polymer matrix with one or more other phases. At least one of the phases releases from the oriented polymer matrix forming voids during the orientation process, thereby reducing the density to less than that of the original unoriented mixture. One or more of the phases may stay bonded to the continuous oriented polymer phase, acting as a reinforcing agent and forming no voids. Methods for forming such a material allowing for the control of the final shape and affecting the final density independent of the composition are also disclosed.
    • 描述了一种方法和材料,其中由具有一个或多个不连续或连续的第二相的连续可取向聚合物基质组成的材料在固态下使用多于一种的装置进行拉伸,以向非取向材料施加力以形成包含 的具有一个或多个其它相的连续取向的聚合物基质。 至少一个相从定向聚合物基质中释放,在取向过程中形成空隙,从而将密度降低到小于原始未取向混合物的密度。 一个或多个相可以保持结合到连续取向的聚合物相上,充当增强剂并且不形成空隙。 还公开了形成这样的材料的方法,其允许控制最终形状并影响独立于组合物的最终密度。

    • A spunbond web formation apparatus includes a spinneret (1) of a spin pack (2) that extrudes an array of fibers (5) that are drawn into an aspirator (6). The attenuated fibers (8) discharged from aspirator (6) are deflected sideways by a Coanda device (7) that entrains the exiting air stream along with the fibers (8). The fibers (8) are deposited on a vertically moving belt (9) and subsequently bonded by calender rolls (20, 21) to form a non-woven spunbond web (40). The spinning distance L is adjusted by vertically moving the aspirator (6), while the laydown distance M is adjusted by horizontally moving the belt (9) or aspirator (6) or by adjusting the size of the Coanda device (7). Deflection of the fibers (8) exiting the aspirator (6) permits the spinning distance L to be adjusted independently of the laydown distance M, without having to move the spin beam (3) or adjust the height of the web-forming belt (9).
    • 纺粘纤维网形成装置包括纺丝组件(2)的喷丝头(1),所述喷丝头(2)挤出吸入吸气器(6)的纤维阵列(5)。 从吸气器(6)排出的减毒纤维(8)由Coanda装置(7)侧向偏转,该装置(7)将排出的空气流与纤维(8)一起夹带。 纤维(8)沉积在垂直移动的带(9)上,随后通过压延辊(20,21)粘合以形成无纺纺粘纤维网(40)。 通过垂直移动吸气器(6)来调节旋转距离L,同时通过水平移动皮带(9)或抽吸器(6)或通过调整柯恩达装置(7)的尺寸来调节沉积距离M. 离开吸气器(6)的纤维(8)的偏转允许旋转距离L独立于沉积距离M进行调节,而不必移动旋转梁(3)或调节幅材成形带(9)的高度 )。
