摘要： An elastic composite formed from a lightweight nonwoven facing that has a low degree of strength in the cross-machine direction ("CD") is provided. Through selective control over certain parameters of the materials employed in the composite and the formation process, the present inventors have discovered that such low strength and lightweight facings may be readily laminated to an elastic film without significantly damaging their integrity. For example, in one embodiment, the elastic film may possess a multi-layered construction that includes an elastomeric elastic layer positioned adjacent to a strength-enhancing thermoplastic layer. The polymer content and thickness of the thermoplastic layer are generally selected to impart additional strength and integrity to the film. Likewise, the polymer content of the elastic layer may also be selected so that the film possesses a sufficient tack for adhering to the facing. In certain cases, it may be desirable to position the layer between two elastic layers so that the strength-enhancing layer does not substantially contact the nonwoven facing. In this manner, the strength-enhancing layer may avoid substantial damage during the lamination process.
摘要翻译：提供了由在横向（“CD”）上具有低强度的轻质无纺织物形成的弹性复合材料。通过对复合材料中使用的材料的某些参数的选择性控制和形成方法，本发明人已经发现，这种低强度和轻质的面层可以容易地层压到弹性膜上而不会显着损害它们的完整性。例如，在一个实施例中，弹性膜可以具有多层结构，其包括邻近增强强度的热塑性层定位的弹性体弹性层。通常选择热塑性层的聚合物含量和厚度以赋予膜额外的强度和完整性。同样地，也可以选择弹性层的聚合物含量，使得该膜具有足够的粘附力以粘附到面层上。在某些情况下，可能需要将层定位在两个弹性层之间，使得强度增强层基本上不接触非织造物面。以这种方式，强化增强层可以避免层压过程中的显着损坏。

摘要： An elastic nonwoven laminate that contains an elastic film laminated to one or more nonwoven facings is provided. The nonwoven facing contains a conventional polyolefin and can also contain a polyolefin-based plastomer. The laminate is activated by grooving to decouple the nonwoven facing from the elastic film. To reduce fiber-pull out that can result due to activation by grooving, the laminate can be post-bonded at room or elevated temperatures and a specific range of pressures to compact the fibers of the facing and minimize fiber pull-out/fuzziness while not sacrificing the softness, elasticity, and feel of the laminate.
摘要翻译：提供包含层压到一个或多个非织造面层的弹性膜的弹性非织造层压材料。非织造面层含有常规聚烯烃，并且还可以含有基于聚烯烃的塑性体。通过开槽将层压板活化以将非织造面层与弹性膜分离。为了减少由于开槽激活可能导致的纤维拉出，可以在室温或升高的温度以及特定的压力范围下对后续粘合进行后粘合，以压实面层的纤维并且最小化纤维拉出/模糊，而不是牺牲了层压板的柔软性，弹性和手感。

摘要： En la presente descripción se describen mejoras en los procesos y equipos para la fabricación de tramas no tejidas compuestas que comprenden una mezcla de dos o más fibras diferentes y formadas a partir de al menos dos corrientes de fibras arrastradas por aire. Adyacente al perímetro de un puerto de salida de una de las corrientes de fibra se encuentra una serie de lengüetas y aberturas separadas. Cuando una primera corriente de fibras arrastradas por aire pasa la serie de lengüetas y aberturas, se forman vórtices en la misma. Cuando se mezcla con una segunda corriente de fibras arrastradas por aire, los vórtices dentro de la primera corriente de fibras provocan una mayor mezcla de las fibras, ayudando a conducir las primeras fibras más profundo en la segunda corriente de fibras arrastradas por aire.

摘要： The present invention provides a method of making a nonwoven web, the method including the steps of providing plurality of fibers and subjecting to a pneumatic force which imparts a velocity to the fibers, reducing the velocity of the fibers in a diffusion chamber which is formed substantially between opposed diverging sidewalls, subjecting the fibers to an applied electrostatic charge, and thereafter collecting the fibers into a web on a moving forming surface. The invention also provides an apparatus for forming nonwoven webs, the apparatus comprising a source of fibers, a fiber attenuation chamber, a diffusion chamber formed substantially between opposed diverging sidewalls, the diffusion chamber located below the fiber attenuation chamber, and a forming surface for collecting the fibers as a nonwoven web.

摘要： A die head assembly for producing meltblown bicomponent fibers in a meltblown apparatus includes a die tip detachably mounted to an underside of a support member. The die tip has a row of channels defined therethrough terminating at exit orifices along a bottom edge of the tip. The channels receive and combine first and second polymers conveyed from the support member. A recess is defined along the top surface of the die tip and defines an upper chamber for each of the die tip channels. A plurality of breaker plates is removably supported in the recess in a stacked configuration. An upper one of the breaker plates has receiving holes defined therein to separately receive polymers from supply passages in the support member. The remaining breaker plates have holes defined therethrough configured to divide the polymers into separately polymer streams and to direct the polymer streams into the die tip channels, the number of polymer streams corresponding to the number of holes in the lowermost breaker plate. The polymer streams combine in the channels prior to being extruded from the orifices as bicomponent polymer fibers.
