The invention relates to a method for obtaining composite fibers, that comprises dispersing colloidal particles in a solvent, injecting the dispersion into a co-flow of a polymer coagulation solution for forming a pre-fiber, circulating the pre-fiber in a duct, extracting, optionally washing and drying the pre-fiber in order to obtain a fiber, and winding the fiber thus obtained, characterized in that the minimum retention time of the fiber within the duct is adjusted so that it has a mechanical strength sufficient to be extracted from the duct, and in that its extraction is vertical and continuous. The invention also relates to composite fibers that can be made according to said method.

The invention concerns a method for obtaining fibers and strips from colloidal particles, characterized in that it consists in: 1) dispersing said particles in a solvent optionally using a surfactant; 2) injecting the resulting dispersion solution through at least an orifice emerging into a flow of an external solution, preferably, having a higher viscosity than said dispersion, the viscosity levels being measured in the same temperature and pressure conditions, so as to cause said particles to agglomerate into fibers or strips by destabilizing the particle dispersions and optionally aligning said particles.
150	Overdyeable pigmented polymeric fiber and yarns and articles made therefrom	US10786685	2004-02-25	US07320766B2	2008-01-22	Sundar Mohan Rao
Dyed yarns typically have inferior color fastness compared with pigmented yarns. However, dyeing offers a virtually infinite selection of colors, flexibility and more uniformity than constructions of pigmented yarns in residential carpet and other yarn applications, such as apparel. It has been found that relatively small amounts of pigment (10 to 1000 ppm) incorporated into polymeric fibers, and particularly nylon fibers used in carpets, creates lightly pigmented yarns which, when overdyed, are highly uniform and have a higher degree of apparent dye light fastness compared to normal dyed yarns. This effect is observable for both anionic and cationic polyamide polymers, and dyeing of these slightly pigmented yarns can be conducted to produce yarns of almost any color of greater depth than the base yarn.
151	Anti-Microbial Fibres and Their Production	US11573129	2005-08-04	US20070243380A1	2007-10-18	Hiran Vegad; Malcolm Hayhurst
Anti-microbial lyocell fibres incorporate an anti-microbial composition which comprises a silver compound deposited on a support material in the form of porous particles having an extended surface area and comprising an oxidic material which is essentially insoluble in water and incapable of forming hydrates. A preferred composition is silver chloride on titanium dioxide particles. The anti-microbial effect is durable to processing and the fibres are not adversely discoloured. Low concentrations of the anti-microbial composition of below 0.1 percent by weight on weight of cellulose may be used. In the process of making the fibres, the anti-microbial composition preferably is added to the pasty pre-mix of the spinning solution.
152	Temperature adaptable textile fibers and method of preparing same	US371779	1989-06-27	US4908238A	1990-03-13	Tyrone L. Vigo; Cynthia M. Zimmerman; Joseph S. Bruno; Gary F. Danna
Temperature adaptable textile fibers are provided in which phase-change or plastic crystalline materials are filled within hollow fibers or impregnated upon non-hollow fibers. The fibers are produced by applying solutions or melts of the phase-change or plastic crystalline materials to the fibers. Cross-linked polyethylene glycol is especially effective as the phase change material, and, in addition to providing temperature adaptability, it imparts improved properties as to soil release, durable press, resistance to static charge, abrasion resistance, pilling resistance and water absorbency.

A method of reducing the number of free carboxyl end groups present in a fiber-forming polymer is given whereby to the polymer minor amounts of a low-boiling oxirane compound such as ethylene oxide are added.
154	Process of melt-spinning high-molecular-weight ethylene terephthalate polymer	US3627867D	1968-09-05	US3627867A	1971-12-14	SCHWARZ ECKHARD CHRISTIAN AUGU
A process and apparatus are disclosed for melt-spinning highmolecular-weight polyethylene terephthalate into high-performance fibers under conditions which reduce the normally high viscosity of such polyester. Ethylene oxide or other low-boiling oxirane compound is injected under pressure into molten polyester before it is fed to the metering pump of the melt-spinning machine. Illustrations show that injection of amounts as small as 0.3 percent provide a substantial reduction in filter pack pressure. The fibers are characterized by low free-carboxyl content and freedom from voids which might be expected from injection of the volatile material.
155	Filtration materials using fiber blends that contain strategically shaped fibers and/or charge control agents	US14582267	2014-12-24	US09909767B2	2018-03-06	Rick L. Chapman
A filtration material comprising a blend of polypropylene and acrylic fibers of round, flat, dog bone, oval or kidney bean shape in any size from 0.08 to 3.3 Dtex. A preferred blend contains about 50 weight percent polypropylene fibers and about 50 weight percent acrylic fibers. The fibers can be blended ranging from 90:10 to 10:90 polypropylene to acrylic. The shape contains 25 weight percent round, flat, oval, dog bone and kidney bean shapes. The fiber blend contains 25 weight percent of at least one size between 0.08 and 3.3 Dtex. Electret fibers incorporated within these blends have 0.02 to 33 weight percent of a charge control agent. These fibers can be used in producing electret material by corona or triboelectric charging methods.
156	SYSTEM AND METHOD FOR APPLICATION OF NANO STAPLE	US13968736	2013-08-16	US20140134346A1	2014-05-15	Michael B. Budai; Eric E. Gardner
A system for the application of nanofiber to a substrate includes a tank having an outlet, an agitator disposed in the tank, a pump located at the tank outlet and an applicator disposed proximate to the substrate. One or more fluid conduits extend from the tank to the pump and from the pump to the applicator. The fluid conduits are configured so as to minimize bends and interferences. The system includes a controller. A nanofiber formulation in a fluid carrier in the tank is pumped from the tank to the applicator for application to the substrate at a predetermined flow rate. The pump is controlled by the controller to vary the output of the pump to match the predetermined flow rate, and the nanofiber formulation is applied by the applicator head at a predetermined coat weight on the substrate. A method for the application of nanofiber to a substrate is disclosed.
157	Solution of PPD-T and PVP and articles made therefrom	US381588	1995-01-31	US5523034A	1996-06-04	Kiu-Seung Lee

159	Membrane filtration type hollow fibers and method for the preparation of same	US831198	1977-09-07	US4234431A	1980-11-18	Mashahiro Mishiro; Tokio Nishikawa; Shigeyasu Ohashi; Yasuo Yokokawa
The invention concerns a membrane filtration type hollow fiber. It is composed of a single material phase which material is a chain high polymer such as cellulose acetate and capable of forming fibers by the spinning of the high polymer. The cylindrical wall defining the hollow fiber represents a three-dimensional net-like structure of fine filtering passages. This structure occupies substantially the whole mass of the tubular wall or a closed ring band zone when seen in any cross-section of the wall, providing thus an effective and active filtering zone. The pore rate amounts to at least 55%, and active points of the filtering passages for governing minimum passable sizes of the passages for solids included in a filtering liquor to be treated upon are distributed at random throughout at least the active zone. These sizes are nearly uniform.
160	Process for producing low carboxyl polyester fibers and other articles	US658315	1976-02-17	US4071504A	1978-01-31	Gailerd L. Korver
There is disclosed an improved process for preparing textile and industrial fibers by melt extruding a polyester resin from melt spinning apparatus to form filaments while adding to and reacting with said polyester resin while in said melt spinning apparatus a monofunctional epoxide wherein the improvement comprises incorporating in said polyester resin prior to extrusion thereof at least one catalytic compound consisting of an alkali metal salt in an amount ranging from about 0.01 to 10.0 parts by weight (calculation based on the alkali metal) per 1000 parts by weight of the polyester.
