Description
METODO PER LA STABILIZZAZIONE DELLE FIBRE DI CARBONIO METHOD FOR THE STABILIZATION OF CARBON FIBERS
La presente invenzione si riferisce ad un metodo per la stabilizzazione delle fibre di carbonio. The present invention relates to a method for stabilizing carbon fibres.
L?utilizzo della fibra di carbonio nel settore tessile e, pi? nello specifico, nella tessitura, per mezzo di telai rettilinei e circolari (tipici della maglieria), ? impossibile a causa della durezza e della mancanza di elasticit? del filato in fibra di carbonio. The use of carbon fiber in the textile sector and, more? specifically, in weaving, by means of straight and circular looms (typical of knitwear), ? impossible due to the hardness and lack of elasticity? of carbon fiber yarn.
Questo ne limita l?utilizzo ed impedisce di beneficiare dei vantaggi per la salute ed il benessere della persona ottenibili grazie alle propriet? del carbonio. This limits its use and prevents you from benefiting from the advantages for the health and well-being of the person obtainable thanks to the properties? of carbon.
La fibra di carbonio, infatti, ? un polimero costituito solo da atomi di carbonio e presenta una elevata conducibilit? elettrica e termica, inerzia chimica ed elevate caratteristiche meccaniche (flessibilit?, modulo elastico e resistenza). The carbon fiber, in fact, ? a polymer made up only of carbon atoms and has a high conductivity? electrical and thermal, chemical inertia and high mechanical characteristics (flexibility, elastic modulus and resistance).
Le fibre di carbonio oggi presenti sul mercato sono piatte e destinate alla tessitura su telai ortogonali, con i quali si ottengono tessuti con varie misure e motivi grafici; in particolare, la fibra piatta ? costituita da migliaia di filamenti paralleli, che vengono classificati in numero di filamenti per titolo e che si presentano in rocche o bobine coniche. The carbon fibers present on the market today are flat and intended for weaving on orthogonal looms, with which fabrics with various sizes and graphic motifs are obtained; in particular, the flat fiber ? made up of thousands of parallel filaments, which are classified in number of filaments by title and which are presented in conical reels or reels.
Per tale motivo, non ? possibile attualmente realizzare, a partire dalla fibra di carbonio, un filato lavorabile ed utilizzabile come filato utile alla tessitura. For that reason, isn't it? It is currently possible to make, starting from carbon fibre, a workable yarn that can be used as a yarn useful for weaving.
Scopo della presente invenzione ? pertanto quello di indicare un metodo per la stabilizzazione delle fibre di carbonio, che sia in grado di trasformare la fibra di carbonio da fibra piatta (composta da migliaia di filamenti in un diametro compreso fra 5 e 15 micron) a filato ritorto utilizzabile nei processi di produzione con telai di tessitura per maglieria. Purpose of the present invention? therefore that of indicating a method for stabilizing carbon fibres, which is capable of transforming carbon fiber from flat fiber (composed of thousands of filaments with a diameter between 5 and 15 microns) into twisted yarn which can be used in the processes of production with weaving looms for knitting.
Questo ed altri scopi vengono conseguiti tramite un metodo per la stabilizzazione delle fibre di carbonio, le cui caratteristiche principali sono specificate nella rivendicazione indipendente 1. This and other objects are achieved through a method for stabilizing carbon fibers, the main characteristics of which are specified in the independent claim 1.
Ulteriori caratteristiche tecniche di dettaglio sono specificate nelle restanti rivendicazioni dipendenti. In modo vantaggioso, il processo di lavorazione alla base del metodo di stabilizzazione secondo la presente invenzione prevede un procedimento di applicazione di resine appositamente realizzate per trattare le fibre di carbonio ed un procedimento di ritorcitura della fibra piatta fino ad ottenere un filato ritorto. Further detailed technical characteristics are specified in the remaining dependent claims. Advantageously, the working process underlying the stabilization method according to the present invention provides for a process for applying resins specially made to treat the carbon fibers and a process for twisting the flat fiber until a twisted yarn is obtained.
La presente invenzione verr? descritta nel seguito secondo forme di realizzazione esemplificative e preferite, ma non limitative. This invention will come described below according to exemplary and preferred, but non-limiting, embodiments.
In particolare, il metodo di stabilizzazione delle fibre di carbonio, secondo la presente invenzione, prevede una prima fase di resinatura, mediante l?impiego di appropriate sostanze; con questa operazione si migliora la resistenza della fibra, nonch? la resistenza dei filamenti alle sollecitazioni di tessitura. In particular, the stabilization method of the carbon fibers, according to the present invention, provides for a first step of resining, through the use of appropriate substances; with this operation you improve the resistance of the fiber, as well as? the resistance of the filaments to weaving stresses.
La sostanza impiegata ? composta da una resina elastomerica acrilica mono-componente a base acquosa, solvente-free, a bassa viscosit?; tali requisiti consentono di favorire la penetrazione all?interno delle fibre, evitando al contempo di creare spessori elevati che possano alterarne la malleabilit?. The substance used? composed of a single-component water-based, solvent-free, low viscosity acrylic elastomeric resin; these requirements make it possible to favor penetration inside the fibers, while avoiding the creation of high thicknesses which could alter their malleability.
Il peso specifico della resina impiegata ? maggiore rispetto a quello del carbonio e l?impregnatura evita il rilascio di eventuali micro-polveri che si potrebbero generare dallo sfregamento e dall?uso successivo dei tessuti finiti. The specific weight of the resin used? greater than that of carbon and the impregnation prevents the release of any micro-dust that could be generated by rubbing and subsequent use of the finished fabrics.
L?operazione di resinatura sopra menzionata si svolge secondo i passaggi seguenti: The above-mentioned resin operation takes place according to the following steps:
- la fibra ? introdotta su appositi cilindri di acciaio di scorrimento ed ? immersa in una vasca apposita ove all?interno si trova la resina appositamente realizzata; - the fiber ? introduced on special sliding steel cylinders and ? immersed in a special tank where the specially made resin is found inside;
- durante il passaggio nella vasca, il filo ? impregnato dalla resina e subisce, all?uscita della vasca, una fase di spremitura, per mezzo di cilindri di gomma a pressione, in modo da ottenere uniformit? di penetrazione sulle fibre, senza avere eccessi in qualche punto; - during the passage in the tank, the wire? impregnated by the resin and undergoes, at the exit of the tank, a squeezing phase, by means of pressure rubber cylinders, in order to obtain uniformity? of penetration on the fibers, without having excesses in some point;
- successivamente, la fibra viene fatta asciugare, in modo da fissare in maniera uniforme la resina, e poi ? fatta scorrere su un inceratore che distribuisce olio anti-statico, al fine di lubrificare e rendere scivolosa la fibra per ridurre l?attrito durante la tessitura. - subsequently, the fiber is dried, in order to fix the resin uniformly, and then ? run over a waxer which distributes anti-static oil, in order to lubricate and make the fiber slippery to reduce friction during weaving.
Vantaggiosamente, a seguito della fase di stabilizzazione sopra descritta ? possibile eseguire una seconda lavorazione di ritorcitura, che conferisce alla fibra ulteriori performance e caratteristiche. Advantageously, following the stabilization step described above ? It is possible to perform a second twisting process, which gives the fiber further performance and characteristics.
In particolare la fase di ritorcitura della fibra di carbonio avviene a secco, in due passaggi. In particular, the carbon fiber twisting phase takes place dry, in two steps.
Dopo essere stata avvolta su fusi, la fibra di carbonio viene ritorta utilizzando specifiche macchine (ritorcitoi) ed alette appositamente modificate. After being wound on spindles, the carbon fiber is twisted using specific machines (twisters) and specially modified fins.
In modo vantaggioso, la fibra di carbonio viene attorcigliata due volte, la prima in senso orario ascendente e poi, nel secondo passaggio, viene attorcigliato in senso inverso discendente. Advantageously, the carbon fiber is twisted twice, first in an upward clockwise direction and then, in the second pass, it is twisted in a downward reverse direction.
Questo permette di ottenere una compattezza omogenea della ritorcitura su tutta la fibra di carbonio conferendole una elasticit? meccanica necessaria per aumentare le possibilit? di tessitura. This allows to obtain a homogeneous compactness of the twisting on the whole carbon fiber giving it an elasticity? mechanics necessary to increase the possibilities? of weaving.
La fibra di carbonio, che da piatta ? ora ritorta, pu? essere utilizzata su macchine rettilinee da tessitura di ultima generazione, che, con appositi alimentatori meccanici (necessari alla corretta alimentazione del filato, sia nella trama che nell?ordito) permette di realizzare tessuti in trama o rasati. The carbon fiber, which is flat? now twisted, can? be used on the latest generation of flat weaving machines which, with special mechanical feeders (necessary for the correct feeding of the yarn, both in the weft and in the warp) allow to create weft or plain weft fabrics.
La macchina di tessitura rettilinea necessita di una schermatura da possibili sviluppi di energia statica causata da micro-polveri che possono eventualmente generarsi nel processo di tessitura. The flat weaving machine requires shielding from possible developments of static energy caused by micro-dusts which may eventually be generated in the weaving process.
In virt? di quanto appena esposto, il metodo di stabilizzazione delle fibre di carbonio, che ? oggetto della presente invenzione, raggiunge gli scopi e realizza i vantaggi sopra menzionati. in virtue of what has just been exposed, the method of stabilization of the carbon fibers, which ? object of the present invention, achieves the aims and realizes the advantages mentioned above.
Eventuali varianti e/o aggiunte possono essere apportate dagli esperti del ramo alla forma realizzativa dell?invenzione qui descritta ed illustrata restando nell?ambito delle rivendicazioni allegate. Possible variations and/or additions can be made by those skilled in the art to the embodiment of the invention described and illustrated herein while remaining within the scope of the attached claims.
