Patent number: 7892622Abstract: 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.Type: GrantFiled: February 11, 2008Date of Patent: February 22, 2011Assignee: Carl Freudenberg KGInventors: Engelbert Löcher, Norbert Goffing, Ararad Emirze

Patent number: 7763295Abstract: 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.Type: GrantFiled: August 31, 2007Date of Patent: July 27, 2010Assignee: Carl Freudenberg KGInventors: Peter Mayr, Peter Muller, Hans Henkes, Norbert Goffing

Publication number: 20090149102Abstract: The object of the invention is to provide splittable fibers (6) which on the one hand are very stable during spinning, i.e., do not dissociate during the entire spinning process and the drawing, and on the other hand after spinning and drawing may be dissociated, essentially completely or even up to 100 percent, into segments (10, 12) or individual filaments. A further object is to keep the technical complexity and energy consumption particularly low. For this purpose, the splittable fibers (6), having at least one break point (8), comprise at least two mutually incompatible polymer components (A, B). At least one polymer component (A) has a lower weight proportion than the other polymer component(s) (B), and the polymer component(s) (A) having the lower weight proportion is situated on and/or in the at least one break point (8).Type: ApplicationFiled: February 11, 2008Publication date: June 11, 2009Applicant: CARL FREUDENBERG KGInventors: Engelbert LOCHER, Norbert GOFFING, Klaus KLEIN, Ararad EMIRZE

Publication number: 20090004943Abstract: The invention relates to a method and a device (2) for manufacturing splittable fibers (1), by means of which it is possible to conduct the melt streams of the two or more mutually incompatible polymer components (A, B) in the melt spinning process in such a way that the flow of one polymer stream around individual polymer streams, or intermingling of the various polymer streams, is prevented, in particular for greatly different weight proportions of the polymer components (A, B). For this purpose, distribution holes (6) are provided upstream from at least one spinning capillary (4), and the cross-sectional area of the at least one distribution hole (6) associated with a particular polymer component (A, B) is adjusted as a function of the volumetric flow of the particular polymer component (A, B).Type: ApplicationFiled: February 11, 2008Publication date: January 1, 2009Applicant: CARL FREUDENBERG KGInventors: Engelbert LOCHER, Klaus KLEIN, Norbert GOFFING, Ararad EMIRZE

Publication number: 20080213531Abstract: The invention relates to a method for the manufacture and use of a tufted nonwoven fabric, wherein fibers for tufts in tuft backing which deviate from a circular fiber cross section are used which exhibit an adhesive force of greater than 40 mN with respect to a tuft yarn, the adhesive force being determined transverse to the longitudinal direction of the fibers. According to the invention, such nonwoven fabrics are used as carpet backing for the manufacture of carpet.Type: ApplicationFiled: February 11, 2008Publication date: September 4, 2008Applicant: CARL FREUDENBERG KGInventors: Norbert GOFFING, Engelbert LOCHER, Ararad EMIRZE

Patent number: 6274521Abstract: 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.Type: GrantFiled: March 7, 2000Date of Patent: August 14, 2001Assignee: Firma Carl FreudenbergInventors: Detlef Barbier, Engelbert Löcher, Ararad Emirze, Norbert Goffing

Patent number: 6164950Abstract: 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.Type: GrantFiled: January 8, 1999Date of Patent: December 26, 2000Assignee: Firma Carl FreudenbergInventors: Detlef Barbier, Engelbert Locher, Norbert Goffing, Jean Baravian, Peter Pfortner, Georges Riboulet, Milton Williams

Patent number: 6053719Abstract: 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.Type: GrantFiled: July 29, 1997Date of Patent: April 25, 2000Assignee: Firma Carl FreudenbergInventors: Detlef Barbier, Engelbert Locher, Ararad Emirze, Norbert Goffing
