Patent number: 8287983Abstract: The invention describes a velour needle-punched nonwoven material, which is produced by placing an optionally pre-strengthened nonwoven material on a brush-like stitch base and needling of the nonwoven on this stitch base. The velour needle-punched nonwoven material according to the invention is characterized in that the nonwoven material comprises a spun-bound nonwoven with filaments, wherein the filaments comprise multicomponent filaments with at least one component with a high melting point and at least one thermally activatable component with a low melting point. The velour needle-punched nonwoven material according to the invention not only has excellent mechanical properties, it is also particularly compatible with the environment and health and therefore suited for applications as a textile lining not only in the private field, but particularly in the public domain.Type: GrantFiled: September 19, 2008Date of Patent: October 16, 2012Assignee: Carl Freudenberg KGInventors: Ararad Emirze, Martin Buechsel, Jan-Peter Zilg, Ulrike Maass, Jeffrey Stine

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
