摘要： A system and methods for collecting and managing air discharged from a melt spinning apparatus. The air management system includes an outer housing defining a first interior space, an intake opening for receiving the discharged air into the first interior space, and an exhaust opening for discharging the air. Positioned within the first interior space is an inner housing defining a second interior space coupled in fluid communication with the exhaust opening and an opening fluidically coupling the first and second interior spaces. The air management system includes a flow control device inside the first interior space that controls the flow of air from the first interior space to the second interior space and an air-directing member outside of the first interior space near the intake opening that extends in a cross-machine direction for dividing the intake opening into two portions in a machine direction.

摘要： This invention relates to a method for preparing nonwoven fabrics having an improved balance of properties in the machine and cross-directions. More specifically, the invention utilizes nonwoven webs that include relatively low levels of multiple-component fibers having latent three-dimensional spiral crimp combined with fibers that do not develop spiral crimp. The latent spiral crimp of the multiple-component fibers is activated, such as by heating, under free shrinkage conditions, after formation of the nonwoven web to achieve re-orientation of the non-spirally-crimpable fibers and an improved balance of properties such as tensile strength and modulus.

摘要： A drawing unit including two or more slits extending in a widthwise direction of a collecting conveyor, each slit including an inlet for sucking groups of filaments pushed out from a spinneret, a path in which air currents flowing in a suction direction is formed for drawing the groups of filaments, and an outlet for blowing out the groups of filaments towards the collecting conveyor after the drawing. The drawing unit and a drawing method are capable of producing a non-woven fabric web with uniform thickness and with only a small number of density spots as a result of reduced entanglement of the filaments in the paths of the drawing unit.

摘要： Nonwoven fabric is formed from a spunbond process by extruding generally ribbon-shaped fibers 126 through slot-shaped orifices 124 of a spinneret 122. The ribbon-shaped fibers are rapidly quenched after extrusion to achieve a substantially uniform molecular orientation throughout a transverse cross section of the fibers, yielding stronger fibers. The rapid quenching results largely from the relatively high aspect ratio (thinness) of the fibers and the relatively large surface area of the fibers, which permits the fibers to quickly cool throughout the transverse cross section. The ribbon-shaped fibers are drawn longitudinally by an aspirator 128 that exerts a generally downward force produced by an air stream that longitudinally stretches and transversely attenuates the ribbon-shaped fibers in such a manner that the transverse cross-sectional shape of the ribbon-shaped fibers enhances the interaction between the air stream and the ribbon-shaped fibers to maximize the downward force. The attenuated ribbon-shaped fibers are deposited onto a web forming surface 134, such as a moving wire screen belt to form a web. The web is then bonded to form the nonwoven fabric.
摘要翻译：无纺布由纺丝方法形成，通过将喷丝板122的槽形孔124大致地挤出丝带状纤维126而形成。带状纤维在挤出之后被快速淬火以在整个横截面的整个横截面中实现基本上均匀的分子取向纤维，产生更强的纤维。快速淬火主要取决于纤维的相对高的纵横比（薄度）和纤维的相对大的表面积，这允许纤维在整个横截面中快速冷却。丝带状纤维由抽吸器128纵向拉伸，抽吸器128施加由空气流产生的大致向下的力，该空气流纵向延伸并横向衰减带状纤维，使得带状纤维的横截面形状纤维增强了空气流和带状纤维之间的相互作用，以使向下的力最大化。减弱的带状纤维被沉积到幅材形成表面134上，例如移动的丝网带以形成网。然后将纸幅粘合以形成无纺织物。

摘要： Described herein are improvements to processes and equipment for the manufacture of nonwoven webs useful in numerous applications including personal care, protective apparel, and industrial products. The fiber and/or filaments used to form the nonwoven fabric are deposited on a forming surface in a controlled orientation using application of an electrostatic charge to the fibers and/or filaments in combination with directing them to an electrode deflector plate while under the influence of the charge. The plate may be made up of teeth with a separation and angle orientation that are selected in accordance with the desired arrangement of the fibers and/or filaments in the nonwoven web. As a result, properties of the web such as relative strengths in the machine direction and cross-machine direction can be controlled.
