The object of the invention is to provide a method which is as simple and economical as possible for manufacturing a tufted product, in particular a tufted top layer of a carpet, having improved nep adhesion properties. For this purpose splittable fibers are used which split on or in the region of the puncture site during tufting.

Method for manufacturing a tufted product, tufted product, and use thereof

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.

Brewing bag and use thereof

Spun nonwoven fabric and apparatus for the manufacture thereof

Rectangular or round spinning nozzle packs for extruding thermoplastic filaments each have both melt channels and orifices for the higher melting polymer compound and also melt channels with orifices through which is passed a polymer compound that melts at a temperature 5 to 50.degree. C. lower. Variously designed insulation channels thermally separate these melt channels, which are operated at different temperatures.

Device for producing spunbonded nonwovens

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.
