Description
DESCRIZIONE DESCRIPTION
La presente invenzione si riferisce in generale al settore tessile e, più in particolare, concerne un nuovo tessuto con elevate proprietà riscaldanti destinato ad essere impiegato per la fabbricazione di indumenti, capi di biancheria per uso personale e domestico, coperte e simili. The present invention relates in general to the textile sector and, more particularly, to a new fabric with high heating properties intended to be used for the manufacture of garments, linen for personal and domestic use, blankets and the like.
I tessuti con proprietà riscaldanti sono da tempo noti nel settore tessile. Essi vengono impiegati nella fabbricazione di indumenti, capi di vestiario e di biancheria, ecc., in grado di mantenere la temperatura di un corpo in essi avvolto ad un valore il più possibile costante, indipendentemente dalle variazioni di temperatura dell'ambiente esterno. Fabrics with warming properties have long been known in the textile sector. They are used in the manufacture of garments, clothing and linen, etc., capable of maintaining the temperature of a body wrapped in them at a value as constant as possible, regardless of the temperature variations of the external environment.
Il principio secondo cui tali tessuti sviluppano le loro proprietà riscaldanti consiste in pratica nell’intrappolare tra le fibre tessili una determinata quantità d'aria che, restandovi sostanzialmente in quiete, viene riscaldata dal corpo e forma uno strato termoisolante. The principle according to which these fabrics develop their heating properties basically consists in trapping a certain amount of air between the textile fibers which, remaining substantially at rest, is heated by the body and forms a heat-insulating layer.
Poiché l’effetto riscaldante di tali tessuti dipende dalla capacità del corpo di riscaldare lo strato d'aria intrappolato tra le fibre tessili, è di per sé evidente che esiste un limite all'effetto riscaldante di tali tessuti legato alla quantità di calore che il corpo è in grado di fornire. Since the heating effect of such fabrics depends on the body's ability to heat the layer of air trapped between the textile fibers, it is in itself evident that there is a limit to the heating effect of such fabrics linked to the amount of heat that the body is able to provide.
Lo scopo della presente invenzione è quindi quello di ovviare all’inconveniente sopraddetto realizzando un tessuto innovativo avente elevate proprietà riscaldanti. The purpose of the present invention is therefore to obviate the aforementioned drawback by making an innovative fabric having high heating properties.
Più in particolare, il tessuto secondo la presente invenzione è formato da un intreccio di fili conduttori e di fibre tessili come fili di ordito oppure di trama, mantenuti elettricamente isolati tra loro, e da almeno una coppia di elettrodi applicati al tessuto e collegati alle estremità di detti fili conduttori in modo da stabilire un campo elettrico di conduzione al loro interno e generare calore per effetto del passaggio di una corrente elettrica. More particularly, the fabric according to the present invention is formed by an intertwining of conductive threads and textile fibers such as warp or weft threads, kept electrically isolated from each other, and by at least one pair of electrodes applied to the fabric and connected at the ends. of said conductive wires so as to establish an electric conduction field inside them and generate heat due to the passage of an electric current.
La presente invenzione verrà ora descritta più in dettaglio con riferimento ad una forma di realizzazione preferita, data qui solamente a titolo esemplificativo e non limitativo ed illustrata nei disegni allegati, in cui: The present invention will now be described in more detail with reference to a preferred embodiment, given here only by way of non-limiting example and illustrated in the attached drawings, in which:
la figura 1 è una vista in pianta dall'alto del tessuto secondo la presente invenzione collegato ad una sorgente di potenza elettrica; Figure 1 is a top plan view of the fabric according to the present invention connected to an electrical power source;
la figura 2 è una vista in sezione parziale del tessuto secondo la presente invenzione eseguita lungo la linea ll-ll di figura 1. Figure 2 is a partial sectional view of the fabric according to the present invention taken along the line ll-ll of Figure 1.
Con riferimento alle figure 1 e 2 dei disegni, in esse è mostrato il tessuto termico dell'invenzione, indicato nel complesso con 10. Il tessuto termico 10 è ottenuto in modo di per sé noto mediante l’intreccio di una serie di fili paralleli 11 che costituiscono l’ordito con una serie di fili paralleli 12 che costituiscono la trama. I fili 11 e 12 sono costituiti da fibre tessili. With reference to figures 1 and 2 of the drawings, they show the thermal fabric of the invention, indicated as a whole with 10. The thermal fabric 10 is obtained in a per se known way by intertwining a series of parallel threads 11 which constitute the warp with a series of parallel threads 12 which constitute the weft. The threads 11 and 12 consist of textile fibers.
Secondo una prima caratteristica dell'invenzione, tra i fili 11 che costituiscono l’ordito sono inclusi fili conduttori 13 che rendono il tessuto 10 elettricamente conduttivo. Naturalmente, tali fili conduttori 13 potrebbero essere inseriti tra i fili di trama 12 anziché tra i fili di ordito 11. According to a first feature of the invention, conductive threads 13 are included between the threads 11 that make up the warp, which make the fabric 10 electrically conductive. Naturally, these conductive yarns 13 could be inserted between the weft yarns 12 instead of between the warp yarns 11.
I fili conduttori 13 sono elettricamente isolati dagli altri fili 11 e 12 e le loro estremità sono collegate ad almeno due elettrodi. In particolare, nella figura 1 si osservano tre elettrodi 14, 15 e 16. Gli elettrodi sono collegati ad un generatore elettrico 17, tipicamente una pila, tramite un circuito elettrico che comprende un interruttore oppure, come nel caso illustrato, un commutatore 19 che cambia il collegamento degli elettrodi 14,15,16 a seconda del minore o maggiore effetto riscaldante che si vuole ottenere. The conductor wires 13 are electrically insulated from the other wires 11 and 12 and their ends are connected to at least two electrodes. In particular, in figure 1 three electrodes 14, 15 and 16 are observed. The electrodes are connected to an electric generator 17, typically a battery, by means of an electric circuit which includes a switch or, as in the case illustrated, a switch 19 which changes the connection of the electrodes 14,15,16 according to the lower or higher heating effect to be obtained.
Secondo un’altra caratteristica dell'invenzione, i fili conduttori 13 sono realizzati in un materiale metallico, preferibilmente acciaio, e presentano sulla loro superficie un rivestimento isolante di un materiale polimero, per esempio una poliammide. According to another feature of the invention, the conductor wires 13 are made of a metal material, preferably steel, and have on their surface an insulating coating of a polymeric material, for example a polyamide.
Secondo un’ulteriore caratteristica dell’invenzione, gli elettrodi 14,15,16 sono realizzati in un materiale sintetico composto per il 94% da una resina sintetica, per esempio poliestere, e per il 6% da un materiale conduttore, per esempio Bechinox in bagno galvanico di nichel. Inoltre, allo scopo di ridurre la resistenza elettrica tra gli elettrodi 14,15,16 ed i fili conduttori 13, tali elettrodi presentano un rivestimento conduttivo applicato allo stato solido, liquido, aeriforme oppure di plasma. According to a further characteristic of the invention, the electrodes 14,15,16 are made of a synthetic material composed for 94% of a synthetic resin, for example polyester, and for 6% of a conductive material, for example Bechinox in galvanic bath of nickel. Furthermore, in order to reduce the electrical resistance between the electrodes 14,15,16 and the conducting wires 13, these electrodes have a conductive coating applied in the solid, liquid, aeriform or plasma state.
Per quanto concerne l’operazione di tessitura del tessuto termico 10 secondo la presente invenzione, essa può essere effettuata tramite un comune telaio. Naturalmente, la scelta del telaio da impiegare dipenderà dalle caratteristiche di flessibilità e di morbidezza che si vorranno ottenere dal tessuto. As regards the weaving operation of the thermal fabric 10 according to the present invention, it can be carried out by means of a common loom. Naturally, the choice of the loom to be used will depend on the characteristics of flexibility and softness to be obtained from the fabric.
Il tessuto termico 10 dell’invenzione può essere impiegato nella fabbricazione di indumenti oppure capi di biancheria riscaldanti. Esso possiede elevate capacità riscaldanti ed è in grado di rendere confortevole la permanenza di un utente in ambienti caratterizzati da temperature anche molto inferiori a quella normale del corpo umano. The thermal fabric 10 of the invention can be used in the manufacture of heating garments or laundry items. It has high heating capacity and is able to make a user's stay comfortable in environments characterized by temperatures even much lower than the normal one of the human body.
