    摘要： The present invention provides a method for reducing a nonwoven fabric to flakes which can be recycled into the spinning system of a meltblowing, spunbonding or carding process. The process according to this invention is a noncontact one, involving the use of a hot air knife. The hot air knife emits a jet, or stream, of heated air under pressure at a high flow rate. A nonwoven fabric is contacted with the jet of air and as a consequence, the nonwoven web is physically broken into small pieces, or flakes. The resultant flakes are brushed off the conveyor and collected in a reclaim hopper; they are readily reprocessable due to their small size.

    摘要翻译： 本发明提供一种将无纺布还原成薄片的方法，该方法可以再循环到熔喷，纺粘或梳理方法的纺丝系统中。 根据本发明的方法是非接触式方法，涉及使用热风刀。 热气刀以高流速在压力下喷射或流出热空气。 非织造织物与空气射流接触，因此非织造纤维网被物理地分成小块或薄片。 将所得薄片从输送机上刷洗并收集在回收料斗中; 它们由于其小尺寸而容易再加工。

    摘要： The invention provides a wipe. The wipes include at least one non-woven web. The web includes an edge portion adjoining a main portion. The web has a top surface and a spaced apart opposite bottom surface and is defined by a width of the web which is perpendicular to a length of the web. The top surface of the main portion defines a top plane and the bottom surface of the main portion defines a bottom plane. The top and bottom planes are parallel to one another and a z-directional dimension of the web extends through the top and bottom planes and is orthogonal to the top and bottom planes. The edge portion includes and edge treatment wherein the edge treatment comprises at least a portion of the edge portion being permanently deformed in a non-random pattern in the z-directional dimension.
