TESSUTO NON TESSUTO PER IL RIVESTIMENTO INTERNO DI MEZZI DI TRASPORTO ATTO AD ADSORBIRE COMPOSTI ORGANICO NON-WOVEN FABRIC FOR THE INTERNAL COVERING OF MEANS OF TRANSPORT SUITABLE FOR ADSORBING ORGANIC COMPOUNDS
VOLATILI BIRDS
La presente invenzione riguarda un tessuto non tessuto per il rivestimento interno di mezzi di trasporto, atto ad adsorbire composti organico volatili. In particolare, la presente invenzione riguarda un tessuto non tessuto atto ad essere inserito nel rivestimento interno di un mezzo di trasporto, come ad esempio un autoveicolo, un treno o un aereo, in cui detto tessuto non tessuto ? trattato in modo tale da trattenere composti organico volatili, in particolare la formaldeide. The present invention relates to a non-woven fabric for the internal lining of means of transport, suitable for adsorbing volatile organic compounds. In particular, the present invention relates to a non-woven fabric suitable for being inserted into the internal lining of a means of transport, such as for example a motor vehicle, a train or an airplane, in which said non-woven fabric is treated in such a way as to retain volatile organic compounds, in particular formaldehyde.
Com?? ben noto, il cielo dei mezzi di trasporto, ossia l?elemento che riveste parte delle superfici interne del mezzo, in particolare le superfici superiori e laterali del mezzo, ? realizzato in un materiale composito termoformato, costituito da diversi strati. Pi? nel dettaglio, un cielo ? solitamente composto, partendo dall?esterno verso l?interno del mezzo, da: How?? well known, the top of the means of transport, i.e. the element that covers part of the internal surfaces of the vehicle, in particular the upper and lateral surfaces of the vehicle, is? made of a thermoformed composite material, consisting of several layers. Pi? in detail, a sky? usually composed, starting from the outside towards the inside of the vehicle, by:
- un primo strato di tessuto non tessuto; - a first layer of non-woven fabric;
- uno strato di resine termo indurenti; - a layer of thermosetting resins;
- uno strato di schiuma di poliuretano; - a layer of polyurethane foam;
- uno strato di fibra di vetro miscelata a resine termo indurenti; - a layer of glass fiber mixed with thermosetting resins;
- un secondo strato di tessuto non tessuto; - a second layer of non-woven fabric;
- uno strato esterno di tessuto a vista. - an outer layer of visible fabric.
In particolare, per quanto concerne gli strati di tessuto non tessuto, attualmente viene principalmente impiegato il tessuto non tessuto in fibra di poliestere, con una grammatura compresa tra i 20 e i 120 gsm, il quale, mediante trattamento idro-oleo repellente, viene utilizzato per la termoformatura del cielo dell?automobile. In particular, as regards the layers of non-woven fabric, currently the non-woven fabric in polyester fiber is mainly used, with a weight of between 20 and 120 gsm, which, by means of a water-oil repellent treatment, is used to the thermoforming of the roof of the car.
Tuttavia, nei cieli ad oggi noti le resine, la schiuma di poliuretano ed altri componenti presenti, come ad esempio le colle (generalmente a spruzzo), costituite ad esempio da resine fenoliche/melamminiche, sviluppano nel tempo dei composti organici volatili (VOC), in particolare la formaldeide. However, in the skies known to date, resins, polyurethane foam and other components present, such as glues (generally by spray), consisting for example of phenolic/melamine resins, develop volatile organic compounds (VOC) over time, especially formaldehyde.
Per risolvere questo problema, negli anni sono stati sviluppati dei componenti con l?obiettivo di ridurre i composti organico volatili, in particolare la formaldeide (numero CAS 50-00-0), in quanto considerata cancerogena e presente nella lista SVHC del Reach (sito ufficiale ECHA). In particolare, sono state selezionate materie prime, quali resine, colle o poliuretani, a basso contenuto di VOC. To solve this problem, components have been developed over the years with the aim of reducing volatile organic compounds, in particular formaldehyde (CAS number 50-00-0), as it is considered carcinogenic and present in the Reach SVHC list (site official ECHA). In particular, raw materials have been selected, such as resins, glues or polyurethanes, with a low VOC content.
Tuttavia, tali soluzioni non hanno portato al risultato desiderato, ossia non erano in grado di ridurre efficientemente la formaldeide e altri composti organico volatili rilasciati dal rivestimento. However, these solutions did not lead to the desired result, i.e. they were not able to efficiently reduce the formaldehyde and other volatile organic compounds released from the coating.
Alla luce di quanto sopra, appare evidente la necessit? di poter disporre di rivestimenti interni di mezzi di trasporto, in particolare cieli, che superino gli svantaggi dei rivestimenti noti. In the light of the above, it is evident the need to be able to have internal linings of means of transport, in particular skies, which overcome the disadvantages of the known linings.
In questo contesto viene ad inserirsi la soluzione secondo la presente invenzione, che si propone di fornire un tessuto non tessuto, atto ad essere inserito nel rivestimento interno di un mezzo di trasporto, in particolare nel cielo di un mezzo di trasporto, trattato in modo tale da trattenere la formaldeide presente o rilasciata dagli altri componenti del rivestimento. In this context, the solution according to the present invention comes into play, which proposes to provide a non-woven fabric, suitable for being inserted into the internal lining of a means of transport, in particular in the roof of a means of transport, treated in such a way to retain the formaldehyde present or released by the other components of the coating.
In particolare, il tessuto non tessuto del rivestimento secondo la presente invenzione ? trattato con una soluzione di adipoidrazide (n. Cas: 1071-93-8; n. CE: 213-999-5; formula: C6H14N4O2) ed ? in grado di trattenere la formaldeide e altre sostanze organico volatili emesse dai suddetti primo e secondo strato intermedio. La adipoidrazide, infatti, ? in grado di legarsi chimicamente alla formaldeide presente o rilasciata da altri componenti presenti in un composito termoformato, come il rivestimento della presente invenzione. Il trattamento degli strati in tessuto non tessuto con adipoidrazide ha evidenziato, nelle prime prove fatte, un sensibile abbassamento del livello di formaldeide se sottoposto a un test di emissione (VOC test). In particular, the non-woven fabric of the covering according to the present invention ? treated with adipohydrazide solution (Cas No: 1071-93-8; EC No: 213-999-5; formula: C6H14N4O2) and ? capable of retaining formaldehyde and other volatile organic substances emitted by the aforementioned first and second intermediate layers. In fact, adipohydrazide? capable of chemically bonding to the formaldehyde present or released from other components present in a thermoformed composite, such as the coating of the present invention. The treatment of the layers in non-woven fabric with adipohydrazide showed, in the first tests carried out, a significant lowering of the level of formaldehyde when subjected to an emission test (VOC test).
Questi ed altri risultati sono ottenuti secondo la presente invenzione proponendo un rivestimento, atto a rivestire internamente mezzi di trasporto, in grado di diminuire il rilascio di sostanze organico volatili, in particolare il rilascio di formaldeide, rispetto ai rivestimenti noti. These and other results are obtained according to the present invention by proposing a coating, suitable for internally coating means of transport, capable of reducing the release of volatile organic substances, in particular the release of formaldehyde, with respect to known coatings.
Scopo della presente invenzione ? quindi quello di realizzare un rivestimento che permetta di superare i limiti delle soluzioni secondo la tecnologia nota e di ottenere i risultati tecnici precedentemente descritti. Ulteriore scopo dell?invenzione ? che detto rivestimento possa essere realizzato con costi sostanzialmente contenuti, sia per quanto riguarda i costi di produzione che per quanto concerne i costi di gestione. Purpose of the present invention? therefore that of realizing a coating which allows to overcome the limits of the solutions according to the known technology and to obtain the previously described technical results. Another purpose of the invention? that said coating can be made with substantially low costs, both as regards production costs and as regards management costs.
Non ultimo scopo dell?invenzione ? quello di realizzare un rivestimento che sia sostanzialmente semplice, sicuro ed affidabile. Not the last purpose of the invention? that of realizing a coating which is substantially simple, safe and reliable.
Forma pertanto oggetto specifico della presente invenzione un tessuto non tessuto atto ad adsorbire composti organici volatili, come la formaldeide, caratterizzato dal fatto di essere impregnato con adipoidrazide. Therefore, a specific object of the present invention is a non-woven fabric suitable for adsorbing volatile organic compounds, such as formaldehyde, characterized in that it is impregnated with adipohydrazide.
Detto tessuto non tessuto (TNT) pu? essere un film, un film accoppiato al tessuto non tessuto, carta, TNT airlaid, TNT wetlaid, TNT tipo chemical bonded, TNT spunbond. Inoltre, detto tessuto non tessuto ha preferibilmente una grammatura compresa tra i 20 e i 150 g/m<2>, ad esempio tra i 20 e i 120 g/m<2>. Said non-woven fabric (TNT) can? be a film, a film coupled to non-woven fabric, paper, airlaid TNT, wetlaid TNT, chemical bonded TNT, spunbond TNT. Furthermore, said non-woven fabric preferably has a basis weight of between 20 and 150 g/m<2>, for example between 20 and 120 g/m<2>.
Il tessuto non tessuto secondo la presente invenzione pu? essere un tessuto non tessuto in fibra di poliestere, in fibra di viscosa o in fibra naturale, come ad esempio fibra di acido polilattico o fibra di bamb?. The non-woven fabric according to the present invention can be a non-woven fabric made of polyester fiber, viscose fiber or natural fiber, such as polylactic acid fiber or bamboo fiber.
Inoltre, il tessuto non tessuto secondo la presente invenzione pu? essere ottenuto con un procedimento scelto tra idroaggrovigliatura, agugliatura meccanica, estrusione, calandratura, preferibilmente idroaggrovigliatura e agugliatura meccanica. I procedimenti di idroaggrovigliatura o di agugliatura meccanica sono preferibili in quanto conferiscono al rivestimento caratteristiche fisicomeccaniche idonee per la termoformatura del cielo. Inoltre, detto tessuto non tessuto ha preferibilmente delle caratteristiche fisico-meccaniche di tipo parallelo, quadrato e/o semi quadrato. In particolare, quando sottoposto a test al dinamometro, detto tessuto non tessuto presenta un certo rapporto di allungamento e un certo rapporto di carico a rottura nei due sensi (trasversale/longitudinale) sulla base del procedimento di produzione del tessuto non tessuto (ossia quando il materiale da fibra passa a essere tessuto non tessuto). Furthermore, the nonwoven fabric according to the present invention can be obtained with a process selected from hydro-entangling, mechanical needle-punching, extrusion, calendering, preferably hydro-entangling and mechanical needle-punching. The hydro-entangling or mechanical needle-punching processes are preferable as they give the covering physical-mechanical characteristics suitable for the thermoforming of the roof. Furthermore, said non-woven fabric preferably has physical-mechanical characteristics of the parallel, square and/or semi-square type. In particular, when subjected to a dynamometer test, said non-woven fabric has a certain elongation ratio and a certain tensile strength ratio in both directions (transverse/longitudinal) on the basis of the production process of the non-woven fabric (i.e. when the fiber material becomes non-woven).
Secondo la presente invenzione, il tessuto non tessuto comprendere una quantit? di adipoidrazide da 0,5% a 30% in peso sul prodotto finito, preferibilmente da 0,5% a 10% in peso. According to the present invention, the nonwoven fabric comprises an amount of adipohydrazide from 0.5% to 30% by weight on the finished product, preferably from 0.5% to 10% by weight.
La presente invenzione concerne anche un procedimento per ottenere un tessuto non tessuto come definito sopra, detto procedimento comprendendo le seguenti fasi: The present invention also relates to a process for obtaining a non-woven fabric as defined above, said process comprising the following steps:
a) mettere in contatto un tessuto non tessuto, ad esempio un tessuto non tessuto in fibra di poliestere, con una soluzione acquosa di adipoidrazide; successivamente a) contacting a non-woven fabric, for example a non-woven fabric made of polyester fiber, with an aqueous solution of adipohydrazide; subsequently
