摘要:
A method of producing a nonwoven textile structure comprises the steps of: (a) stretching a plurality of substantially parallel continuous tow filaments (1) of absorbent material, such as cellulose acetate or solvent spun rayon, to provide a filament assembly, (b) consolidating the resulting filament assembly (4) by a compacting operation (at 5) to produce a three-dimensional rod or pack while maintaining substantially uninterrupted capillary along the entire length of the filament assembly, and (c) wrapping the three-dimensional rod or pack (6) in a water porous material (7). A plurality of the resulting wrapped rods or packs (9) may then be incorporated into a composite structure, such as that used for a thin diaper. Such wrapped rods or packs exhibit excellent fluid transmission and wet strength characteristics.

制造非织造织物结构的方法包括以下步骤:(a)拉伸多个基本上平行的吸收材料的连续丝束(1),例如乙酸纤维素或溶剂纺丝人造丝,以提供丝组装,(b) 通过压实操作(5)固结所得到的细丝组件(4),以产生三维棒或包,同时沿丝细丝组件的整个长度保持基本上不间断的毛细管,和(c)将三维棒或 (6)在水多孔材料(7)中。 然后可以将多个所形成的包裹的棒或包装(9)结合到诸如用于薄尿布的复合结构中。 这种包裹的棒或包装表现出优异的流体传播和湿强度特性。
