ВОЛОКНА ИЗ ВОЗОБНОВЛЯЕМЫХ СЛОЖНЫХ ПОЛИЭФИРОВ, ИМЕЮЩИЕ НИЗКУЮ ПЛОТНОСТЬ

FIELD: chemistry. SUBSTANCE: fibers are obtained from a thermoplastic composition which comprises hard renewable polyester, has a porous structure and a low density. To obtain such a structure, a renewable polyester is mixed with a polymer additive that increases the impact strength, so that the additive can be dispersed as discrete physical domains in a continuous matrix of renewable polyester. Then, fibers are formed which is subjected to tension or stretching at a temperature below the glass transition temperature of the polyester, i.e. subjected to cold drawing. The deformation force and stress at elongation during stretching leads to disruption of adhesion in the renewable polyester matrixin the areas adjacent to the discrete domains. As a result a mesh structure is obtained of pores located near the discrete domains, which by their proximity may form bridges between the pore boundaries, acting as internal structural "hinges" that promote stabilization of the mesh structure and increase its ability to dissipate energy. EFFECT: obtaining of fibers from renewable polyester with low density and good mechanical properties. 20 cl, 2 dwg, 8 tbl, 11 ex РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 620 415 C2 (51) МПК D01F 6/92 (2006.01) D01F 1/10 (2006.01) D04H 1/724 (2012.01) D01D 5/08 (2006.01) D02G 3/00 (2006.01) A61F 13/15 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ФОРМУЛА (21)(22) Заявка: ИЗОБРЕТЕНИЯ К ПАТЕНТУ РОССИЙСКОЙ ФЕДЕРАЦИИ 2014135462, 28.01.2013 (24) Дата начала отсчета срока действия патента: 28.01.2013 Дата регистрации: (73) Патентообладатель(и): КИМБЕРЛИ-КЛАРК ВОРЛДВАЙД, ИНК.

Renewable polyester fibers having a low density.

Se proporcionan fibras que se forman a partir de una composición termoplástica que contiene un poliéster renovable rígido y tiene una estructura porosa y baja densidad. Para lograr una estructura de este tipo, el poliéster renovable se mezcla con un aditivo endurecedor polimérico en el cual el aditivo endurecedor puede dispersarse como dominios físicos discretos dentro de una matriz continua del poliéster renovable. Las fibras se forman después de eso y después se estiran o se extraen a una temperatura por debajo de la temperatura de transición vítrea del poliéster (es decir "estiramiento en frio") sin pretender estar limitados por la teoría, los presentes inventores creen que la fuerza de deformación y el alargamiento de elongación del proceso de estiramiento provoca que se produzca la pérdida de adherencia en la matriz de poliéster renovable en las zonas localizadas adyacentes qa los dominios discretos. Esto crea una red de cavidades (por ejemplo, microcavidades, nanocavidades, o una combinación de las mismas) localizadas adyacentes a los dominios discretos, las cuales como resultado de su localización cercana, pueden formar un puente entre los limites de las cavidades y actuar como "bisagras" estructurales internas que ayudan a estabilizar la red y aumenta su capacidad para disipar energía.

FIBRAS DE POLIÉSTER RENOVÁVEIS COM BAIXA DENSIDADE. São fornecidas fibras que são formadas por um composto termoplástico que contém um poliéster rígido renovável e apresenta uma estrutura com vazios e baixa densidade. Para obter tal estrutura, o poliéster renovável é misturado a um aditivo de endurecimento polimérico, em que o aditivo de endurecimento pode ser disperso como domínios físicos discretos, dentro de uma matriz contínua do poliéster renovável. As fibras são assim formadas e então esticadas ou puxadas a uma temperatura abaixo da temperatura de transição vítrea do poliéster (ou seja, "puxado a frio"). Sem a intenção de se limitarem pela teoria, estes inventores acreditam que a força de deformação e a tensão de alongamento do processo de tração provoca a desintegração da matriz do poliéster renovável, nas áreas adjacentes aos domínios discretos. Isso cria uma rede de vazios, (por exemplo, micro-vazios, nano-vazios ou uma combinação deles) localizada em posição adjacente aos domínios discretos, o que, como resultado de suas localizações próximas, podem formar uma ponte entre as fronteiras dos vazios e agir como dobradiças estruturais internas que ajudam a estabilizar a rede e aumentam sua capacidade de dissipação de energia.

Thereafter, the fibers are formed and then stretched or stretched at a temperature lower than the glass transition temperature of the polyester (i.e., "low temperature stretching").

Without intending to be limited by theory, the present inventors believe that the deformation force and elongational strain of the drawing process causes debonding to occur in the renewable polyester matrix at those areas located adjacent to the discrete domains. This creates a network of voids (e.g., micro-voids, nano-voids, or a combination thereof) located adjacent to the discrete domains, which as a result of their proximal location, can form a bridge between the boundaries of the voids and act as internal structural "hinges" that help stabilize the network and increase its ability to dissipate energy.

Renewable polyester fibers having a low density

Renewable polyester fibers having a low density.

Se proporcionan fibras que se forman a partir de una composición termoplástica que contiene un poliéster renovable rígido y tiene una estructura porosa y baja densidad. Para lograr una estructura de este tipo, el poliéster renovable se mezcla con un aditivo endurecedor polimérico en el cual el aditivo endurecedor puede dispersarse como dominios físicos discretos dentro de una matriz continua del poliéster renovable. Las fibras se forman después de eso y después se estiran o se extraen a una temperatura por debajo de la temperatura de transición vítrea del poliéster (es decir "estiramiento en frio") sin pretender estar limitados por la teoría, los presentes inventores creen que la fuerza de deformación y el alargamiento de elongación del proceso de estiramiento provoca que se produzca la pérdida de adherencia en la matriz de poliéster renovable en las zonas localizadas adyacentes qa los dominios discretos. Esto crea una red de cavidades (por ejemplo, microcavidades, nanocavidades, o una combinación de las mismas) localizadas adyacentes a los dominios discretos, las cuales como resultado de su localización cercana, pueden formar un puente entre los limites de las cavidades y actuar como "bisagras" estructurales internas que ayudan a estabilizar la red y aumenta su capacidad para disipar energía.

In versions, an assembly is presented having relatively isotropic physical properties across at least one of its planes and above-indicated density and another assembly having relatively isotropic physical properties and the same density. Material composition is also presented containing assembly of above-mentioned carbon filaments with volume density 0.001-0.5 g/cu.cm and a composite. The latter includes assembly of the same filaments and a second component made of particles of solid or electrically active material or catalytically active metal or metal-containing compound, in which case assembly has volume density 0.001-0.50 g/cu. cm and contains second component up to 50 parts per 1 part of filaments. Another composite contains assembly with filaments having "c" axes, the same density, and second component: metal or compound in number up to 50 parts per 1 part of filaments. Methods for manufacturing filament assembly and second material involve dispersing filaments or filaments and material and separating resultant assembly, having volume density 0.001-0.50 g/cu. cm, from medium. Method of forming porous mat or sheet (with volume density 0.001-0.50 g/cu.cm) involves dispersing above-mentioned filaments in water or organic solvent to form dispersion with less than 10 wt % of filaments and filtration. One more version of method of manufacturing assembly involves dispersing filaments and separating ...

Polymer blend, polymer solution composition and fibers spun from the polymer blend and filtration applications thereof

The invention relates to a web or filter structure such as the filtration media comprising a collection of fiber comprising a first polymer and a second polymer in a fine fiber or fine fiber web structure. The combination of two polymers provides improved fiber rheology in that the fiber has excellent temperature and mechanical stability. The combination of polymers imparts the properties of elasticity or tackiness, which is desirable for adhering particles to the fiber web, with high temperature resistance.

Improvements in and connected with the Manufacture of Threads for Woven Fabrics and the like from Wood, Bamboo, Straw and like Fibres.

24,596. Kron, R. Oct. 31, 1912, [Convention date]. Yarns specially doubled, fabrics with; materials special, fabrics containing; paper fabrics; yarns, beaming. - Threads suitable for the cheapest sacking and packing fabrics, carpets, stair carpets, wall materials, &c., are made from short fibre wood, bamboo, straw, and like vegetable growths, which are felted to a wide fibre web, and longitudinal strips of from 4-40 millimetres width are folded or otherwise laid together to form flat, non-twisted strips of a fraction of their width, tearing being avoided by the folding of the edges. The threads may be made on weft-winding, cop-winding, beaming, or dressing machines, or even on looms, by simply interposing seamers or like folding- devices. The strips may be craped or goffered, and jute, cotton, wool, or like cores may be used. The threads may be rippled or corrugated transversely, and the layers may be glued or sized and made waterproof.
