DESCRIZIONE dell'invenzione avente per TITOLO: DESCRIPTION of the invention having as TITLE:
"Procedimento per ottenere, a partire dalla carta, un materiale composito paragonabile ad un tessuto per caratteristiche meccaniche ed estetiche", "Process to obtain, starting from paper, a composite material comparable to a fabric for mechanical and aesthetic characteristics",
La presente intenzione consiste in uno specifico trattamento del materiale cartaceo al fine di ottenere un materiale composito a superficie piana, sottile e flessibile, avente caratteristiche, di resistenza meccanica ed un effetto tattile.par.agonabile ad un tessuto. In quanto tale, esso può essere destinato alla realizzazione di prodotti che di tessuto sono fatti o rivestiti, in tutto o in parte. A titolo esemplificativo, si faccia riferimento ad accessori, capi di abbigliamento, elementi di arredo e tappezzeria in generale. Con il termine 'materiale cartaceo' si fa riferimento (in modo non esclusivo) a pagine di carta stampata e non, proveniente da riviste, libri, giornali, disegni, fotografie, cartoline e confezioni di prodotti alimentari e non. The present intention consists in a specific treatment of the paper material in order to obtain a composite material with a flat, thin and flexible surface, having characteristics of mechanical resistance and a tactile effect comparable to a fabric. As such, it can be intended for the production of products that are made of or covered in fabric, in whole or in part. By way of example, reference is made to accessories, clothing, furnishings and upholstery in general. The term 'paper material' refers (in a non-exclusive way) to pages of printed and non-printed paper, coming from magazines, books, newspapers, drawings, photographs, postcards and packaging of food and non-food products.
La presente invenzione intende ovviare alle problematiche che le caratteristiche proprie del materiale cartaceo presentano nel momento in cui questo viene utilizzato per scopi che non gli sono propri, come la produzione dì oggetti rivestiti di - o realizzati nella loro interezza con - la carta. Tra le problematiche riscontrate si faccia riferimento al carattere assorbente della carta, nonché alla sua scarsa resistenza all'usura ed allo strappo. Ciò fa sì che la certa si -riveli essere un materiale di per sé non adatto ad essere cucito né sottoposto a sollecitazioni o agenti atmosferici (umidità, esposizione a radiazioni solari e sostanze liquide). The present invention intends to obviate the problems that the characteristics of the paper material present when it is used for purposes that are not proper to it, such as the production of objects coated with - or made in their entirety with - paper. Among the problems encountered, reference should be made to the absorbent nature of the paper, as well as its poor resistance to wear and tear. This means that the certain is revealed to be a material in itself not suitable for sewing or subjected to stress or atmospheric agents (humidity, exposure to solar radiation and liquid substances).
La tecnica conosciuta al momento in cui la descrizione è compilata prevede una plastificazione del materiale cartaceo.-Tuttavia,. tale soluzione altera sostanzialmente l'effetto al tatto del materiale composito ottenuto, che diventa rigido e più simile alla plastica che al tessuto, determinando inoltre delle prestazioni non soddisfacenti di detto materiale, . specialmente se impiegato nella realizzazione di elementi di tappezzeria o capi di abbigliamento. The technique known at the time the description is compiled involves a lamination of the paper material. this solution substantially alters the touch effect of the composite material obtained, which becomes rigid and more similar to plastic than to fabric, further determining unsatisfactory performances of said material. especially if used in the production of upholstery elements or garments.
Con un procedimento differente, la presente invenzione mira a realizzare un materiale composito capace di resistere a eventuali trazioni trasversali e longitudinali, allo strappo, all'accartocciamento e all'usura, che garantisca un'eccellente impermeabilità a sostanze liquide, pur mantenendo una buona permeabilità al vapore. La finalità principale di questa invenzione è di proteggere il materiale cartaceo impiegato, attribuendogli al tempo stesso l'aspetto di un 'tessuto'. Infatti, tale procedimento attribuisce al materiale composito una buona proprietà elastica e antimacchia; rendendolo assimilabile a tutti gli effetti ad un tessuto, quindi facilmente cucibile e indicato per la realizzazione di accessori quali, a titolo esemplificativo, borse e portafogli; tappezzeria, capi di abbigliamento ed elementi di arredo. Il particolare pregio estetico è dato da una serie di elementi: le immagini della carta utilizzata secondo una selezione accorta,- la possibilità di realizzare composizioni artistiche con la carta, restituendo al materiale finito l'effetto tattile e visivo di tessuto. With a different process, the present invention aims to produce a composite material capable of resisting any transverse and longitudinal traction, tearing, wrinkling and wear, which guarantees excellent impermeability to liquid substances, while maintaining good permeability. steamed. The main purpose of this invention is to protect the paper material used, while at the same time giving it the appearance of a 'fabric'. In fact, this process gives the composite material a good elastic and stain-resistant property; making it comparable in all respects to a fabric, therefore easy to sew and suitable for making accessories such as, by way of example, bags and wallets; upholstery, clothing and furnishings. The particular aesthetic value is given by a series of elements: the images of the paper used according to a careful selection, - the possibility of creating artistic compositions with paper, restoring the tactile and visual effect of fabric to the finished material.
Gli obiettivi esposti sono raggiunti grazie alle caratteristiche della rivendicazione 1. Ovvero, attraverso l'utilizzo di tre materiali che, aggiunti alla carta (elemento essenziale di detto materiale composito, Fig. 1 e Fig. 2 lettera D), vanno a formare il materiale composito oggetto della presente invenzione. Essi sono: un materiale avente una struttura reticolare (quale, ad esempio, la fibra di vetro, Fig. 1 e Fig. 2 lèttera A), una guaina liquida elastomerica in dispersione acquosa (Fig. 1 e Fig. 2 lettera B) ed il 'tessuto non tessuto' o 'velo di vetro' (Fig. 1 e Fig. 2 lettera C). The objectives set out are achieved thanks to the characteristics of claim 1. That is, through the use of three materials which, added to the paper (an essential element of said composite material, Fig. 1 and Fig. 2 letter D), form the material composite object of the present invention. They are: a material having a reticular structure (such as, for example, glass fiber, Fig. 1 and Fig. 2 letter A), an elastomeric liquid sheath in aqueous dispersion (Fig. 1 and Fig. 2 letter B) and the 'non-woven fabric' or 'glass fleece' (Fig. 1 and Fig. 2 letter C).
L'invenzione è spiegata nel dettaglio tramite un esempio di' realizzazione rappresentato nei disegni: FIG. 1 Assonometria degli strati che compongono il materiale composito ottenuto con il procedimento; FIG. 2 Sezione degli strati che compongono il materiale composito ottenuto con il procedimento. The invention is explained in detail by means of an embodiment shown in the drawings: FIG. 1 Axonometry of the layers that make up the composite material obtained with the process; FIG. 2 Section of the layers that make up the composite material obtained with the process.
Il procedimento di realizzazione presenta sette fasi. The manufacturing process has seven steps.
1. La prima fase consiste nella stesura di una rete a maglia stretta (con interstizi di circa 1 mm per 1 mm, Fig. 1 e Fig. 2 lettera A) che può essere, a titolo esemplificativo, di fibra di vetro o materiali naturali quali lino, cotone, iuta. Tale strato attribuisce alla carta una maggiore resistenza a trazione nelle direzioni di zero e novanta gradi e costituisce la base su cui verranno applicati gli strati successivi. 1. The first phase consists in the drafting of a tightly meshed net (with interstices of about 1 mm by 1 mm, Fig. 1 and Fig. 2 letter A) which can be, by way of example, of glass fiber or natural materials such as linen, cotton, jute. This layer gives the paper greater tensile strength in the directions of zero and ninety degrees and forms the basis on which subsequent layers will be applied.
2. La seconda fase prevede l'applicazione di una guaina liquida elastomerica in dispersione acquosa (Fig. 1 e Fig. 2 lettera B). Tale guaina può all'occorrenza essere sostituita da un materiale che abbia caratteristiche ed effetto simili. La guaina è applicata, in via preferenziale ma non esclusiva, per mezzo di un pennello, in quantità tale da riempire gli interstizi della rete descritta al punto 1. Tale guaina funge da legante tra la rete (al punto 1) ed il 'tessuto non tessuto' o 'velo di vetro' (punto 3). 2. The second phase involves the application of an elastomeric liquid sheath in aqueous dispersion (Fig. 1 and Fig. 2 letter B). If necessary, this sheath can be replaced by a material having similar characteristics and effect. The sheath is applied, preferentially but not exclusively, by means of a brush, in such quantity as to fill the interstices of the mesh described in point 1. This sheath acts as a binder between the mesh (in point 1) and the non-woven fabric. fabric 'or' glass fleece '(point 3).
3. La terza fase prevede l'applicazione di uno strato, a scelta, di 'tessuto non tessuto' o 'velo di vetro' (Fig. 1 e Fig. 2 lettera C) di dimensioni corrispondenti a quelle della rete (presentata al punto 1). Tale strato va steso in modo da ottenere . una perfetta aderenza alla rete, facendolo impregnare della guaina (menzionata al punto 2). A questo scopo può essere utilizzato un rullo dì gomma dura, il quale - una volta pressato sul 'tessuto non tessuto' o 'velo di vetro' - permette la fuoriuscita laterale della guaina in eccedenza e assicura l'aderenza tra gli strati 1 e 3. Lo strato di 'tessuto non tessuto' o 'velo di vetro' consente di creare una superficie piana su cui posare i ritagli di carta, ai quali attribuisce una resistenza meccanica a trazioni multidirezionali. 3. The third phase involves the application of a layer, optionally, of 'non-woven fabric' or 'glass fleece' (Fig. 1 and Fig. 2 letter C) with dimensions corresponding to those of the mesh (presented in point 1). This layer must be spread in such a way as to obtain. a perfect adherence to the net, making it impregnate with the sheath (mentioned in point 2). For this purpose, a hard rubber roller can be used, which - once pressed on the 'non-woven fabric' or 'glass film' - allows the excess sheath to come out from the side and ensures adherence between layers 1 and 3. The layer of 'non-woven fabric' or 'glass fleece' allows you to create a flat surface on which to place the paper scraps, to which it gives mechanical resistance to multidirectional traction.
4. La quarta fase prevede un'ulteriore applicazione della guaina menzionata al punto 2 con lo stesso procedimento della fase 2 (Fig. 1 e Fig. 2 lettera B). 4. The fourth phase involves a further application of the sheath mentioned in point 2 with the same procedure as in phase 2 (Fig. 1 and Fig. 2 letter B).
5. La quinta fase prevede l'applicazione della carta (Fig. 1 e Fig. 2 lettera D) sul 'tessuto non tessuto' o 'velo di vetro' (punto 3) ricoperto di guaina (punto 4). Tali ritagli di carta vengono precedentemente immersi in acqua per un ammontare di tempo necessario a seconda del tipo e della grammatura della carta, al fine di permetterne l'allargamento delle fibre e la. successiva penetrazione della guaina all'interno delle stesse. Al fine di ottenere una perfetta aderenza tra il 'tessuto non tessuto' o 'velo di vetro' (punto 3) e la carta (punto 5) si utilizza - a titolo -preferenziale ma non esclusivo - un rullo a gomma dura, con il quale viene effettuata una pressione sul materiale a tal punto raggiunto, in modo da agevolare la penetrazione della guaina (punto 4) all'interno delle fibre della carta e farne fuoriuscire la quantità in eccesso. 5. The fifth phase involves applying the paper (Fig. 1 and Fig. 2 letter D) on the 'non-woven fabric' or 'glass fleece' (point 3) covered with a sheath (point 4). These paper scraps are previously immersed in water for an amount of time necessary depending on the type and weight of the paper, in order to allow the fibers to spread and the. subsequent penetration of the sheath inside them. In order to obtain a perfect adhesion between the 'non-woven fabric' or 'glass fleece' (point 3) and the paper (point 5), a hard rubber roller is used - preferentially but not exclusively - with the which a pressure is made on the material to such a point reached, in order to facilitate the penetration of the sheath (point 4) inside the fibers of the paper and to let the excess amount come out.
6. La sesta fase consiste nell'applicazione di una guaina (Fig. 1 e Fig. 2 lettera B), che può essere quella utilizzata nelle fasi 2 e 4 a condizione che sia di colore trasparente, in quanto deve consentire la visibilità della carta sottostante. Come nelle fasi 2 e 4 la guaina viene applicata, in via preferenziale ma non esclusiva, tramite un pennello. 6. The sixth phase consists in the application of a sheath (Fig. 1 and Fig. 2 letter B), which can be the one used in phases 2 and 4 provided that it is transparent, as it must allow the visibility of the paper below. As in phases 2 and 4, the sheath is applied, preferentially but not exclusively, using a brush.
7. La settima fase prevede l'applicazione di un ulteriore strato di 'tessuto non tessuto' o 'velo di vetro' (Fig. 1 e Fig. 2 lettera C) di dimensioni corrispondenti a quelle della rete al punto 1. La grammatura e la trama di detto 'tessuto non tessuto' o 'velo di vetro' può variare a seconda del risultato che si vuole ottenere. Una grammatura leggera (pari a circa '17' grammi al metro quadrato) consente una maggiore trasparenza, permettendo così la visibilità della carta sottostante. Tale fase è importante in quanto il 'tessuto non tessuto' o 'velo di vetro' applicato:-^ crea una superficie uniforme (ad esempio minimizzando eventuali disiivelli dovuti alle sovrapposizioni dei ritagli di carta); ii) incrementa la resistenza meccanica a trazione del materiale composito ottenuto; iii) protegge la carta da eventuali abrasioni superficiali e dall'azione di agenti atmosferici; iv) è responsabile dell'effetto al tatto e alla vista simile ad un tessuto. 7. The seventh phase involves the application of a further layer of 'non-woven fabric' or 'glass fleece' (Fig. 1 and Fig. 2 letter C) with dimensions corresponding to those of the mesh in point 1. The weight and the weft of said 'non-woven fabric' or 'glass fleece' can vary according to the desired result. A light weight (equal to about '17' grams per square meter) allows greater transparency, thus allowing the visibility of the underlying paper. This step is important since the applied 'non-woven fabric' or 'glass fleece': creates a uniform surface (for example by minimizing any unevenness due to the overlapping of the paper scraps); ii) increases the mechanical tensile strength of the composite material obtained; iii) protects the paper from any surface abrasions and the action of atmospheric agents; iv) is responsible for the effect to the touch and sight similar to a fabric.
Al termine del procedimento in sette fasi, il materiale ottenuto, pur dimostrando una notevole resistenza a trazione, mantiene un'eccellente flessibilità. Da notare la facilità e la velocità di realizzazione, che non necessita di tempi di attesa tra una fase e l'altra, nonché la possibile industrializzazione del procedimento. At the end of the seven-step process, the material obtained, while demonstrating a remarkable tensile strength, maintains excellent flexibility. Note the ease and speed of production, which does not require waiting times between one phase and another, as well as the possible industrialization of the process.
Qualora si desideri ottenere una maggiore impermeabilizzazione del materiale così realizzato, è possibile applicare un'ulteriore strato di guaina sul 'tessuto non tessuto' o 'velo di vetro' menzionato al punto 7. in tal caso è consigliabile pressare la guaina aggiunta con l'utilizzo di un rullo a gomma dura (come menzionato in precedenza), al fine di far penetrare la guaina all'interno del 'tessuto non tessuto' o 'velo di vetro' ed eliminare il materiale in eccedenza. Così facendo si ottiene una maggiore trasparenza dello strato di 'tessuto non tessuto' o 'velo di vetro', ed una maggioreimpermeabilizzazione del materiale composito, pur senza If it is desired to obtain a greater waterproofing of the material thus obtained, it is possible to apply an additional layer of sheath on the 'non-woven fabric' or 'glass fleece' mentioned in point 7. in this case it is advisable to press the sheath added with the use of a hard rubber roller (as previously mentioned), in order to make the sheath penetrate inside the 'non-woven fabric' or 'glass fleece' and eliminate the excess material. By doing so, a greater transparency of the layer of 'non-woven fabric' or 'glass fleece' is obtained, and a greater waterproofing of the composite material, even without
