    摘要： A spun nonwoven fabric contains monofilaments and bicomponent filaments, the spun nonwoven fabric having, over its cross section, different quantities of the bicomponent filaments. The bicomponent filaments contain at least two outward-facing segments made of a binding component. The proportions of bicomponent filaments over the cross sectional planes of the spun nonwoven fabric can be in a range of approximately 1% to 100% by weight. The cross sectional planes of the nonwoven fabric containing the different proportions of bicomponent filaments transition into one another without detectable phase boundaries. The apparatus for manufacturing the nonwoven fabric contains at least one, and may contain up to forty or more, spinneret devices, such as rectangular spinneret plates or round spinneret disks. The spinneret devices may be arranged in rows or in staggered arrangement above a linearly moving collector belt. Spinning orifices on the spinneret devices are respectively dedicated to producing a monofilament or a bicomponent filament from a melt and, viewed in the direction of motion of the collector belt, are arranged with respect to one another so as to correspond in their totality to the cross sectional structure of different filament types in the nonwoven fabric.

    摘要： An infusion bag made of a nonwoven textile fabric is described, which includes fibers and/or filaments made of at least one filter material, the textile fabric having a hot-sealable surface which is formed by hot-sealable fibers and/or filaments made of at least one hot-sealable material. It is provided according to the present invention that the fibers and/or filaments made of the filter material and the fibers and/or filaments made of the hot-sealable material are present in the textile fabric in the form of a mixture, the proportion of the fibers and/or filaments made of the hot-sealable material increasing over the cross section toward the hot-sealable surface of the textile fiber as a gradient. The infusion bag according to the present invention is characterized by excellent filtering properties, high visual transparency, and an excellent pop-up function and is manufacturable simply and economically as a single-layer product. It is particularly well-suited for use as a tea bag or a coffee pod.
