摘要： Nonwoven fibrous webs are formed including a first group and a second group of fibers, where fibers of the first group are imparted with a degree of shrinkage that differs from a degree of shrinkage imparted to fibers in the second group. During or after bonding of the web, the web may be subjected to heat treatment causing fibers in one of the groups to shrink a greater amount in comparison to fibers in the other group, resulting in nonwoven products with desired textures and other physical characteristics.

摘要： A spin-texture process for producing polyamide yarns is described in which a freshly extruded yarn is passed between two pairs of rotating rolls and then collected. The second pair of rolls (draw rolls) is driven at a peripheral speed greater than that of the first pair of rolls (feed roll and its associated separator roll). The feed roll is maintained and a given temperature which is correlated with other processing conditions to impart a desired level of latent crimp to the yarn. Yarns prepared by the process have a potential bulk of between 10% and 50% and are particularly useful as carpet yarns.

摘要： An apparatus for controlling airflow in a fiber extrusion process includes a fiber flow region between an inlet through which extruded fibers are received and an outlet through which the extruded fibers are discharged and at least one surface providing a boundary between the fiber flow region and another region, wherein the surface includes apertures permitting air to flow between the fiber flow region and the other region to control airflow at the outlet of the fiber flow region. The apparatus can include a housing which contains at least one chamber, with the surface forming a boundary between the fiber flow region and the chamber, such that the apertures permit air to flow between the fiber flow region and at the chamber. In a spunbond process, the airflow control device receives drawn filaments exiting an aspirator and deposits the filaments onto a web-forming surface with reduced air disturbance.

摘要： The dissolution of dissolvable components in plural component polymer fibers is achieved by providing a polymer fiber including at least two sections, where at least one fiber section includes a dissolvable component. The rate at which at least part of the fiber dissolves is controlled by at least one of a fiber section having a non-round cross-sectional geometry, and at least two fiber sections including two different dissolvable components. In an exemplary embodiment, island-in-the-sea fibers are formed with non-round and elongated cross-sectional geometries. In another embodiment, sheath-core fibers are formed in which the sheath and core include different dissolvable components.

摘要： A molten polymer filtration assembly includes at least three independently controllable and removable filter housings which extend from a common inlet passage to a common outlet passage, thereby providing parallel flow paths for polymer filtration. Each of the filter housings includes an inlet valve controlling the flow of polymer from the inlet passage, an outlet valve controlling the flow of polymer to the outlet passage, and a filtration passage which extends between the inlet and outlet valves and houses a candle-type filtration element. When the inlet and outlet valves are opened, the filter housing is on-stream and allows polymer to flow from the inlet to the outlet passage. Each filter housing is individually controllable, and can be set in an on-stream state independent of the state of any of the other filter housings, such that any number of filter housings can be on-stream at a given time. By setting the number of on-stream filter housing in correspondence with the polymer flow rate, the polymer residence time can be maintained in a relatively narrow range of durations over a wide range of polymer flow rates, thereby ensuring that the polymer residence time within the filtration system remains below an acceptable duration and that the polymer residence time is regulated to avoid significant fluctuation or variances in the polymer residence time. Interlocks prevent the closure of the outlet valve of each filter housing unless the inlet valve for that housing is closed. Removal of any filter housing is prevented unless its valves are both closed.
