    Abstract: The present invention relates to a process for the manufacture of structural hybrid thermoplastic composites where organic and inorganic fibers are well dispersed in a thermoplastic matrix. The process comprises defibrillating the organic fibers with or without the presence of surface active agents using a mixer at a high shear and at a temperature lower than the decomposition temperature of organic fibers and melting point of the surface active agents to separate the hydrogen bonded fibers and generate microfibers, followed by blending and dispersion of the organic fibers in the thermoplastic matrix to produce a fiber composite, followed by further blending and dispersion of the fiber composite with inorganic fibers at a low shear to get the moldable hybrid composite, followed by extrusion, injection or compression-injection molding. Low shear mixing maintains the inorganic fiber length.

    Abstract: Thermally expandable crimped hollow fibers having expandable regions interconnected with crimped portions are provided. The crimped hollow fibers may be formed from any hollow polymer fiber that is capable of being crimped and is reactive to heat. Pressure, such as from two opposed mating crimping dies, is applied to portions of a hollow polymer fiber to compress or crimp portions of the fiber, thereby leaving uncrimped or expandable regions containing an expandable substance. In use, the crimped hollow fibers may be contacted with cellulose fibers in the wet-end section of the paper-making process and the resulting mixture formed into a web of entangled fibers. Heat from the dryer section expands the expandable substance in the expandable portion of the crimped hollow fiber to bulk the thus formed paper product. The crimped hollow fibers are especially useful in papers having a basis weight from about 20 to about 200 gsm.

  • Patent number: 7850899
    Abstract: 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.

  • Patent number: 7833447
    Abstract: 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.

  • Patent number: 7799424
    Abstract: A resin composition includes an aliphatic polyester resin. The resin has carboxyl groups at the end termini of the molecular chain and at least one compound represented by the general formula (I), the compound being added to the resin to cap a part or all of the carboxyl groups at the end termini of the molecular chain of the resin. A process for producing a fiber includes mixing a pellet comprising an aliphatic polyester resin having carboxyl groups at the end termini of the molecular chain with a compound represented by the general formula (I) so that the content of the compound becomes 0.1 to 8% by weight and then melt-spinning the resulting mixture under the conditions of a spinning temperature of 200 to 250 C.°, a melt residence time of 180 to 1800 sec and a spinning rate of 500 to 10000 m/min.

  • Publication number: 20100159186
    Abstract: In a first aspect the invention is a solid core fibrillation-resistant, synthetic polymeric filament having three substantially equal length convex sides. The sides through substantially rounded tips centered by a distance “a” from the axis of the filament. Each rounded tip has a radius substantially equal to a length “b”. Each tip lies on a circumscribed circle having a radius substantially equal to a length (a+b) and the midpoint of each side lies on an inscribed circle having a radius substantially equal to a length “c”. The filament has a denier-per-filament in the range 10<“dpf”<35; the distance “a” lies in the range 0.00025 inches (6 micrometers)<“a”<0.004 inches (102 micrometers); the distance “b” lies in the range from 0.00008 inches (2 micrometers)<“b”<0.001 inches (24 micrometers); the distance “c” lies in the range from 0.0003 inches (8 micrometers)<“c”<0.0025 inches (64 micrometers); and the modification ratio (“MR”) lies in the range from about 1.1<“MR”<about 2.0.
