Publication number: 20110095448Abstract: Method and apparatus for longitudinal orientation of thermoplastic film material (4) comprises a width-reduction zone upstream of the longitudinal stretching zone, through which the width of the film is gradually reduced so as to allow longitudinal stretching without necking. The width-reduction zone comprises at least one, preferably several, pairs of pleating rollers (16, 17) comprising intermeshing grooves or discs for pleating the material, the length of said width reduction zone preferably being less than 3 times the original width of the film. The width-reducing zone has upstream (14) and downstream (15) rollers or roller assemblies, with curved axes and optionally also conveyor belts for providing smooth width reduction. Longitudinal stretching is preferably between at least two, and preferably more than two, pairs of stretching rollers (9, 10, 11, 12) which are relatively close together.Type: ApplicationFiled: October 30, 2008Publication date: April 28, 2011Inventor: Ole-Bendt Rasmussen

Publication number: 20110092934Abstract: A process is described for producing thin crimped tows from LOY, POY, or FOY filaments in a total linear density from 2 ktex to 9 ktex by filament yarns being withdrawn from creeled bobbins, folded and provided with a processing finish, then drawn or tension-uniformized and thereafter heated and stufferbox crimped. The process can be carried out in-line with numerous further processing operations. The tows are particularly useful for producing textile hygiene articles such as diapers, sanitary napkins, inserts and incontinence guards and the like.Type: ApplicationFiled: July 2, 2010Publication date: April 21, 2011Applicant: Trevira GmbHInventors: Jörg Dahringer, Michael Klanert, Bernd A.

Patent number: 7927528Abstract: A beaded preform includes a plurality of adjacently positioned beads for forming a plurality of voids in an engineered material. The beaded preforms may be comprised of a filaments (single strand of beads) and mats (two-dimensional and three dimensional arrays of beads). The filaments and mats may be coated to become tows and laminates, respectively, which may then be assembled into composite materials. The preforms may be produced using novel manufacturing apparatuses and methods, and incorporated into known manufacturing processes to produce porous structures, including stress-steering structures, in any material including metals, plastics, ceramics, textiles, papers, and biological materials, for example.Type: GrantFiled: July 26, 2004Date of Patent: April 19, 2011Inventor: Charles R. Owens

Patent number: 7922849Abstract: Process of manufacturing spun-bonded fabric, using naturally crimped filaments, whereby the filaments are passed through a stretching unit and finally through a diffusor. The filaments are thereupon layered on a layering device, as crimped filaments. The layered filaments together with the layering device are passed through a solidifying device in which the filaments are solidified by means of a fluid.Type: GrantFiled: May 8, 2006Date of Patent: April 12, 2011Assignee: Reifenhauser GmbH & Co. KG. MaschinenfabrikInventors: Sebastian Sommer, Wilhelm Frey

Patent number: 7850899Abstract: A web is made by first extruding multicomponent filaments from a spinneret and then passing the extruded filaments through a process air shaft. Cold air is directed against the filaments in the process air shaft to cool and aerodynamically stretch the filaments while excluding the entry of other air into the process air shaft. The cooled and stretched multicomponent filaments are then deposited in a mat on a support, and then the mat of multicomponent filaments to a web is consolidated by subjecting it to water jets at a pressure of 10 bar to 200 bar such that the multicomponent filaments fuse together at crossover points and the filaments have a considerable free length between crossover points where they are fused. Finally the web is heat treated to crinkle the filaments thereof and bulk of the web.Type: GrantFiled: February 13, 2007Date of Patent: December 14, 2010Assignee: Reifenhauser GmbH & Co.
