Description
Descrizione dell'Invenzione Industriale dal titolo: Description of the Industrial Invention entitled:
"PROCEDIMENTO PER LA PRODUZIONE DI MOQUETTE "PROCEDURE FOR THE PRODUCTION OF CARPETS
RICICLABILE E MOQUETTE COSI' OTTENUTA" a nome della ditta RECYCLABLE AND CARPET SO OBTAINED "in the name of the company
La presente invenzione ha per oggetto un procedimento per la produzione di un materiale tessile per il rivestimento di pavimenti, in particolare una moquette, riciclabile. L'invenzione riguarda inoltre il materiale tessile per il rivestimento di pavimenti realizzato con detto procedimento. Più precisamente l'invenzione si riferisce a quei materiali tessili di rivestimento per pavimenti sottoposti ad un utilizzo intenso e concentrato in un ristretto periodo di tempo, ad esempio durante una manifestazione .espositiva, e destinati ad essere rimossi dopo l'uso. The present invention relates to a process for the production of a textile material for covering floors, in particular a carpet, which can be recycled. The invention also relates to the textile material for covering floors made with said process. More precisely, the invention relates to those textile floor covering materials subjected to intense and concentrated use in a short period of time, for example during an exhibition, and intended to be removed after use.
Attualmente, i materiali tessili di rivestimento per questa tipologia di utilizzi sono realizzati in materiali sintetici, essenzialmente per ragioni di costo, comprendono uno strato agotrattato in fibra sintetica prevalentemente poliolefinica ed in particolare polipropilenica, tenuto insieme da uno strato di resina legante applicata su una sua faccia. Tipicamente, quale resina legante si usa una soluzione acquosa (lattice) di copolimero stirene-butadiene contenente vari additivi e. cariche, ad esempio carbonato di calcio e idrossido di alluminio, per aumentarne la consistenza e le proprietà ignifughe, addensanti per il controllo della sua fluidità, ed altri. Il lattice può -essere applicato mediante rullo spanditore pescante in una vasca di raccolta del lattice medesimo, o con altra tecnica equivalente, e quindi il semilavorato imbevuto del lattice viene riscaldato per provocare l'evaporazione dell'acqua e l'essiccamento del legante . Currently, the textile coating materials for this type of use are made of synthetic materials, essentially for cost reasons, they comprise a needle-treated layer in synthetic fiber, mainly polyolefin and in particular polypropylene, held together by a layer of binder resin applied to one of its face. Typically, an aqueous (latex) solution of styrene-butadiene copolymer containing various additives is used as the binder resin. fillers, for example calcium carbonate and aluminum hydroxide, to increase its consistency and fire-retardant properties, thickeners to control its fluidity, and others. The latex can be applied by means of a dip spreader roller in a collection tank of the latex itself, or with another equivalent technique, and then the semi-finished product soaked in the latex is heated to cause the evaporation of the water and the drying of the binder.
L'applicazione al pavimento di questo tipo di moquette viene realizzata mediante l'impiego di nastro biadesivo che ne consente anche la sua agevole rimozione dopo l'uso. The application to the floor of this type of carpet is achieved by using double-sided tape which also allows it to be easily removed after use.
L'inconveniente più grave che si riscontra nell'uso di questo tipo di moquette consiste nel fatto che, una volta rimossa al termine della manifestazione fieristica, essa deve essere smaltita in discarica con costi non indifferenti per l'utilizzatore e con danno rilevante sotto il profilo ecologico. Tenendo conto della estensione delle superfici che vengono complessivamente coperte con moquette in queste manifestazioni e della frequenza di esse, ben si comprende come i volumi di materiale da smaltire siano notevolmente grandi e quindi quanto sentito sia questo problema. The most serious drawback that is encountered in the use of this type of carpet consists in the fact that, once removed at the end of the fair, it must be disposed of in landfills with considerable costs for the user and with significant damage under the ecological profile. Taking into account the extension of the surfaces that are covered with carpet in these events and the frequency of them, it is well understood how the volumes of material to be disposed of are remarkably large and therefore how much this problem is felt.
Lo scopo della presente invenzione è di fornire un procedimento per la produzione di un materiale tessile per il rivestimento di pavimenti che possa essere riciclato dopo l'uso attraverso un trattamento che non danneggi la fibra consentendo quindi il recupero almeno di quest 'ultima e la sua reimmissione nel ciclo produttivo. The object of the present invention is to provide a process for the production of a textile material for floor covering that can be recycled after use through a treatment that does not damage the fiber, thus allowing the recovery of at least the latter and its reintroduction into the production cycle.
Uno scopo particolare della presente invenzione è di fornire un procedimento del tipo summenzionato che consenta anche il recupero del legante. A particular object of the present invention is to provide a process of the aforementioned type which also allows the recovery of the binder.
Un ulteriore scopo della presente invenzione è di fornire una moquette che presenti la proprietà di essere riciclabile dopo il suo utilizzo. A further object of the present invention is to provide a carpet which has the property of being recyclable after its use.
Questi scopi vengono raggiunti con il procedimento per la produzione di un materiale tessile per il rivestimento di pavimenti le cui caratteristiche sono indicate nella rivendicazione 1, nonché con il prodotto ottenuto da tale procedimento le cui caratteristiche sono indicate nella rivendicazione 11. These objects are achieved with the process for the production of a textile material for floor covering, the characteristics of which are indicated in claim 1, as well as with the product obtained by this process, the characteristics of which are indicated in claim 11.
Caratteristiche e vantaggi del procedimento e del prodotto secondo l'invenzione risulteranno più chiaramente dalla descrizione che segue di una sua forma realizzativa, fatta a titolo esemplificativo e non limitativo, con riferimento alla figura annessa in cui il procedimento secondo l'invenzione è mostrato schematicamente. Characteristics and advantages of the process and of the product according to the invention will become clearer from the following description of an embodiment thereof, given by way of non-limiting example, with reference to the attached figure in which the process according to the invention is schematically shown.
Con riferimento alla suddetta figura, il processo secondo l'invenzione si basa, convenzionalmente, sull 'utilizzo di fibre sintetiche ricevute in balle che vengono sottoposte ad un trattamento di preparazione, indicato con 1 consistente in una lavorazione in una macchina denominata "apriballe" 2 che ha lo scopo di omogeneizzare la partita per colore e tipo di fibra (denaratura, lunghezza, cretto, composizione). Una prima grossolana apertura degli ammassi fibrosi, compattati a causa dello stazionamento all'interno delle balle, viene realizzata in una macchina 3 cosiddetta "carda-lupo" e quindi si provvede all'aggiunta di olio di lubrificazione alle fibre semiaperte per farle scivolare tra loro in una, cosiddetta, cella di unzione 4. With reference to the aforementioned figure, the process according to the invention is conventionally based on the use of synthetic fibers received in bales that are subjected to a preparation treatment, indicated with 1 consisting of a processing in a machine called "bale openers" 2 which has the purpose of homogenizing the batch by color and type of fiber (denier, length, cretto, composition). A first rough opening of the fibrous masses, compacted due to the stationing inside the bales, is carried out in a so-called "wolf-carder" machine 3 and then lubrication oil is added to the semi-open fibers to make them slide between them in a so-called anointing cell 4.
Il composto fibroso così preparato, o "mista", viene quindi avviato alla fase successiva di produzione di un pannello fibroso grezzo o feltro, indicata con 5. In questa fase il composto fibroso viene ripetutamente ventilato in camere di stoccaggio 6 a cui viene ricircolato mediante apposito apparecchio denominato "fresa" 7. Il composto così omogeneizzato viene inviato all'impianto di cardatura 8 comprendente: un caricatore 9 che riceve la fibra dalle camere 6 e la posa in,modo omogeneo e sotto forma di materasso sul trasportatore dell'impianto: una macchina cardatrice 10 composta di una serie di cilindri dentati a diametro diverso che provvedono alla parallelizzazione delle fibre ed al deposito delle stesse su un nastro trasportatore sotto forma di un velo leggero ed omogeneo: un apparecchio faldatore 11 che raccoglie il velo uscente dalla carda e 10 deposita a più strati su un nastro trasportatore che alimenta l'impianto di agugliatura 12. L'agugliatura è realizzata in una serie di macchine agugliatrici che tramite l'azione di una pluralità di aghi in movimento alternativo veloce in senso ortogonale alla direzione di avanzamento del materasso fibroso catturano le fibre e le trascinano attraverso la massa fibrosa legandola e compattandola. All'uscita dell'impianto di agugliatura il semilavorato assume l'aspetto di un feltro che viene inviato al successivo processo di finitura. The fibrous compound thus prepared, or "mixed", is then sent to the next phase of production of a raw fibrous panel or felt, indicated with 5. In this phase the fibrous compound is repeatedly ventilated in storage chambers 6 to which it is recirculated by means of special apparatus called "cutter" 7. The homogenized compound is sent to the carding plant 8 comprising: a loader 9 which receives the fiber from the chambers 6 and is laid homogeneously and in the form of a mattress on the conveyor of the plant: a carding machine 10 composed of a series of toothed cylinders with different diameters which parallelize the fibers and deposit them on a conveyor belt in the form of a light and homogeneous web: a lapper 11 which collects the web coming out of the card and 10 deposits in several layers on a conveyor belt that feeds the needle punching system 12. Needle punching is carried out in a series of needle punching machines which, through the action of a plurality of needles in fast reciprocating motion in a direction orthogonal to the direction of advancement of the fibrous mattress, capture the fibers and drag them through the fibrous mass, binding and compacting it. At the exit of the needling system, the semi-finished product takes on the appearance of a felt that is sent to the subsequent finishing process.
In questa fase viene applicato sul rovescio del feltro un legante in sospensione acquosa contenuta in una vasca 13 mediante un rullo spanditore 14 pescante entro di essa. In this step, a binder in aqueous suspension contained in a tank 13 is applied to the back of the felt by means of a spreader roller 14 drawn within it.
11 feltro imbevuto del legante viene passato in un tunnel di asciugatura ventilato 15 ad aria calda, ("rameuse"), dove tutta 1 'acqua viene rimossa per evaporazione producendo uno strato flessibile e consolidato sul rovescio del feltro. All’uscita del forno il prodotto finito viene inviato ad una unità di confezionamento 16. The felt soaked in the binder is passed into a ventilated drying tunnel 15 with hot air ("rameuse"), where all the water is removed by evaporation, producing a flexible and consolidated layer on the back of the felt. Upon exiting the oven, the finished product is sent to a packaging unit 16.
Secondo l'invenzione, il legante è una resina vinilica resistente all'acqua e presentante funzionalità idrolizzabili in misura sufficiente a risultare solubile a caldo in una soluzione fortemente basica. Una resina vinilica che presenta tale proprietà è costituita da polivinilacetato omopolimero e/o copolimero, in questo secondo caso essendo copolimerizzato con almeno uno dei seguenti composti: According to the invention, the binder is a vinyl resin resistant to water and having hydrolysable functionalities to a sufficient extent to be soluble when hot in a strongly basic solution.

- alcoli polivinilici a grado di idrolisi compreso tra 50 e 100 e viscosità della soluzione acquosa al 4% compresa tra 4 e 50 mPa.s. In una forma realizzativa preferita, la resina è un copolimero di esteri vinilici e maleici quale acetato di vinile e butilmaleato nella percentuale 85/15. - polyvinyl alcohols with a degree of hydrolysis between 50 and 100 and viscosity of the aqueous solution at 4% between 4 and 50 mPa.s. In a preferred embodiment, the resin is a copolymer of vinyl and maleic esters such as vinyl acetate and butyl maleate in the 85/15 percentage.
Nella sua pratica attuazione, la sospensione acquosa del legante contenuta nella vasca 13 e applicata al rovescio del feltro è costituita oltre che dalla resina vinilica suddetta, da una carica inerte -formata da idrossido di alluminio o carbonato di calcio',·. un addensante e acqua. In its practical embodiment, the aqueous suspension of the binder contained in the tank 13 and applied to the reverse of the felt is constituted not only by the aforementioned vinyl resin, but also by an inert filler formed by aluminum hydroxide or calcium carbonate. a thickener and water.
La composizione percentuale in peso del bagno legante è mediamente la seguente: The percentage composition by weight of the binder bath is on average the following:
resina vinilica 20-40% vinyl resin 20-40%
carica inerte 40-70% inert charge 40-70%
addensanti 1- 5% thickeners 1- 5%
acqua 5-35% water 5-35%
Vantaggiosamente è presente anche un plastificante preferibilmente un plastificante molecolare della serie ftalica, isoftalica, benzoica e fosforica ad esempio un dimetilftalato o equivalenti. Advantageously, a plasticizer is also present, preferably a molecular plasticizer of the phthalic, isophthalic, benzoic and phosphoric series, for example a dimethyl phthalate or equivalent.
Il plastificante può costituire da 0 a 40% del bagno legante in funzione della sofficità che si desidera conferire al prodotto. The plasticizer can make up from 0 to 40% of the binder bath depending on the softness to be given to the product.
In una composizione particolarmente preferita del composto legante utilizzato nel procedimento secondo 1<1 >invenzione la resina legante è il prodotto commerciale VINAVIL 19 WM e la carica inerte è idrossido di alluminio nelle rispettive percentuali del 27 e del 54% in peso. In questo caso si ottiene un prodotto dotato di proprietà ignifughe. Se la resistenza al fuoco non è indispensabile, può essere usato carbonato di calcio in alternativa. In a particularly preferred composition of the binder compound used in the process according to the invention, the binder resin is the commercial product VINAVIL 19 WM and the inert filler is aluminum hydroxide in the respective percentages of 27 and 54% by weight. In this case, a product with flame retardant properties is obtained. If fire resistance is not essential, calcium carbonate can be used as an alternative.
La densità del composto legante viene regolata in modo da avere una quantità applicata, su base umida, compresa tra 400 e 1000 g/m<2>. The density of the binder compound is adjusted so as to have an applied quantity, on a wet basis, between 400 and 1000 g / m <2>.
La moquette realizzata con il procedimento secondo l'invenzione è formata, come una moquette nota, da uno strato di tessuto non tessuto agotrattato in fibra sintetica ed uno strato di legante resinoso applicato ad una sua faccia. Essa presenta le medesime caratteristiche meccaniche di una moquette realizzata convenzionalmente, ma presenta la proprietà aggiuntiva che lo strato di legante può venire solubilizzato completamente in una soluzione fortemente basica ad esempio di NaOH al 5-30%, proprietà che viene vantaggiosamente sfruttata nel processo di recupero della moquette usata, come descritto in una corrispondente domanda di brevetto depositata in pari data dalla medesima richiedente. The carpet made with the method according to the invention is formed, like a known carpet, by a layer of needle-treated non-woven fabric in synthetic fiber and a layer of resinous binder applied to one of its faces. It has the same mechanical characteristics of a conventionally made carpet, but has the additional property that the binder layer can be completely solubilized in a strongly basic solution, for example 5-30% NaOH, a property that is advantageously exploited in the recovery process. of the used carpet, as described in a corresponding patent application filed on the same date by the same applicant.
La moquette secondo l'invenzione, una volta rimossa dopo l'uso, viene dapprima separata da eventuali resti di biadesivo e da sporcizia grossolana e quindi viene sottoposta a lavaggio con una soluzione fortemente basica ad esempio con un bagno caustico per NaOH al 15%. In tali condizioni si ha la completa solubilizzazione dello strato legante e la fibra può essere recuperata e riciclata. La soluzione contenente il legante e la carica inerte in sospensione può essere anch'essa riutilizzata per acidificazione con separazione dell'acqua, che può essere reimmessa nelle acque di processo, e di un precipitato costituito dal legante miscelato alla carica che può essere riutilizzato per formare composti leganti per altri materiali di rivestimento. The carpet according to the invention, once removed after use, is first separated from any remains of double-sided adhesive and coarse dirt and then is washed with a strongly basic solution, for example with a caustic bath for 15% NaOH. Under these conditions, the binder layer is completely dissolved and the fiber can be recovered and recycled. The solution containing the binder and the inert filler in suspension can also be reused by acidification with separation of the water, which can be reintroduced into the process water, and of a precipitate consisting of the binder mixed with the filler which can be reused to form binding compounds for other coating materials.
Il tipo di fibra sintetica preferita è il polipropilene, sia per ragioni di costo, sia per le sue caratteristiche di idrofobicità, resistenza agli acidi e alla luce. Ad essa può essere vantaggiosamente aggiunta una certa percentuale di fibra modacrilica e/o poliestere ignifuga, nella misura compresa tra il 10 e il 50%, per migliorare le caratteristiche di resistenza al fuoco e per rendere il prodotto conforme alle normative previste nel luogo di installazione. Il peso finale del manufatto è compreso tra circa 400 e 900 g/m<2>. The preferred type of synthetic fiber is polypropylene, both for cost reasons and for its characteristics of hydrophobicity, resistance to acids and light. It can be advantageously added a certain percentage of modacrylic and / or fire-retardant polyester fiber, to the extent between 10 and 50%, to improve the characteristics of fire resistance and to make the product compliant with the regulations envisaged in the place of installation. . The final weight of the product is between about 400 and 900 g / m <2>.
Varianti e/o modifiche potranno essere apportate al procedimento per produrre materiali di rivestimento per pavimenti e al materiale realizzato con detto procedimento, in conformità alla presente invenzione, senza per questo uscire dall'ambito protettivo dell'invenzione medesima. Variations and / or modifications may be made to the process for producing floor covering materials and to the material made with said process, in accordance with the present invention, without thereby departing from the protective scope of the invention itself.
