    摘要： The present invention relates to an absorbent fibrous product containing at least 50% of cotton fibers or other cellulose fibers and less than 0.1% of a chemical or hot-melt binder, including a first layer consisting of hydroentangled non-woven fabric and a second layer consisting of fibers that are more weakly bonded together than the fibers of the first layer, the bonding of the fibers of the second layer resulting from a hydrophilic treatment of the layer of fibers, the two layers being bonded by adhesion of the entire surface between the fibers of the two layers, and the debonding force being at least 0.1 N. The invention also relates to a manufacturing method, which includes the following steps: a) forming at least two separate laps of fibers, one of which is at least partially made of cotton fibers or other cellulose fibers; b) consolidating a first of said laps by bonding using fine water jets; c) stacking the laps; and d) the hydrophilic treatment of the formed complex lap by means of wetting, followed by extracting the liquid, in particular by subjecting the lap to negative pressure.

    摘要翻译： 本发明涉及吸收性纤维产品含棉纤维或其它的纤维素纤维的至少50％和化学或热熔粘合剂的小于0.1％，包括：第一层由......组成水刺无纺织物和第二层 纤维的组成没有比第一层，第二层由纤维层的亲水性处理所得的纤维的粘合的纤维更弱键合在一起时，两层由之间的整个表面的粘合结合 两个层的纤维，并且该剥离力为至少0.1 N.因此，本发明涉及的制造方法，其中包括以下步骤：a）形成纤维的至少两个分开的圈数，的全部，其至少部分地由一个 的棉纤维或其它纤维素纤维; b）中固结第一-的-说搭接通过使用细水刀的粘接; c）中堆叠所述圈; 和d）通过润湿的方式亲水化处理形成的复合物的圈，然后通过使一圈压力提取液，特别是负的。
