Descrizione della domanda di brevetto per invenzione: Invention patent application description:
?Tessuto migliorato specialmente adatto per capi di abbigliamento, borse ed accessori per abbigliamento, calzature o loro parti?. ?Improved fabric especially suitable for garments, bags and accessories for clothing, footwear or parts thereof?.
Descrizione Description
Il presente trovato si riferisce ad un tessuto, che pu? essere impermeabile, tipicamente anche se non esclusivamente adatto a capi di abbigliamento, a borse ed accessori per abbigliamento, a calzature o loro parti. Pu? essere inoltre anche utilizzato in ambito di arredamento di interni oppure arredamento di esterni, come tessuto per rivestimento di interni di automobili, yacht, tender, treni e mezzi di trasporto in genere. The present invention refers to a fabric which can be waterproof, typically though not exclusively suitable for garments, bags and accessories for clothing, footwear or parts thereof. Can? it can also also be used in the field of interior furnishings or exterior furnishings, as a fabric for covering the interiors of cars, yachts, tenders, trains and means of transport in general.
Come noto, i settori sopra menzionati, in particolar modo il settore dell?abbigliamento, delle borse, degli accessori per abbigliamento e delle calzature sono settori dove la moda cambia di continuo e gli standard qualitativi dei tessuti utilizzati sono spesso molto elevati, in quanto gli utilizzatori e/o il pubblico di riferimento sono molto esigenti nel pretendere prodotti ed applicazioni che siano al contempo performanti (in termini di durata ciclo-vita), sostenibili ? in termini di a basso impatto ambientale. As known, the sectors mentioned above, especially the clothing, handbags, clothing accessories and footwear sectors are sectors where fashion changes continuously and the quality standards of the fabrics used are often very high, as the Are users and/or the reference public very demanding in demanding products and applications that are both high-performing (in terms of cycle-life), sustainable? in terms of low environmental impact.
In detti settori sopra menzionati vengono spesso richiesti tessuti leggeri, versatili, antipiega, innovativi nell?aspetto, flessibili, comodi, confortevoli e durevoli, facilmente lavabili, antimacchia, eventualmente isolanti dal punto di vista termico nonch? eventualmente impermeabili. In said sectors mentioned above, light, versatile, wrinkle-resistant, innovative in appearance, flexible, comfortable and durable, easily washable, stain-resistant, possibly thermally insulating as well as durable fabrics are often required. possibly waterproof.
Risulta spesso difficile riuscire a produrre tessuti che abbiano tutte le caratteristiche che la moda esige nei settori sopra indicati e che sono sopra riportate. It is often difficult to be able to produce fabrics that have all the characteristics that fashion requires in the sectors indicated above and which are indicated above.
Infatti, spesso vengono prodotti tessuti antipiega che sono anche impermeabili, ma che sono di aspetto relativamente poco piacevole. Altre volte vengono prodotti tessuti innovativi nell?aspetto, ma poco comodi oppure poco flessibili. In fact, wrinkle-free fabrics are often produced which are also waterproof, but which are relatively unattractive in appearance. Other times innovative fabrics are produced in appearance, but not very comfortable or not very flexible.
Altre volte i tessuti realizzati sono flessibili, ma non sono antipiega e risultano quindi, durante l?uso, poco consoni e quindi poco adatti all?uso in alcuni ambienti specialmente formali. Other times the fabrics made are flexible, but are not crease-resistant and are therefore, during use, not very suitable and therefore not very suitable for use in some especially formal environments.
Tutti questi sono inconvenienti non trascurabili che sono difficili da superare in modo da avere un tessuto che abbia aspetti prevalentemente se non unicamente vantaggiosi. All these are non-negligible drawbacks which are difficult to overcome in order to have a fabric which has predominantly if not solely advantageous aspects.
E? stato sorprendentemente trovato un nuovo tessuto migliorato che supera tutti gli inconvenienti sopra riportati e pu? essere vantaggiosamente e facilmente prodotto con il procedimento secondo l?invenzione. AND? Surprisingly, a new improved fabric has been found that overcomes all the above drawbacks and can? be advantageously and easily produced with the process according to the invention.
Si mette in rilievo che anche il procedimento dell?invenzione ? vantaggioso: infatti molti procedimenti noti nell?arte, come quello descritto in IT1412994 prevedono una deposizione manuale su un pannello di tessuto (es. 1 metro quadrato) della dispersione (compound) a base di sughero, di fatto un sistema artigianale che richiede degli spazi enormi per permettere l?asciugatura del tessuto con applicata la dispersione (compound) a base di sughero, materiale pi? tempi enormi legati al processo di asciugatura pi? spazi, solo esemplificativamente per deporre ed asciugare 50 m<2 >di pannelli di tessuti sarebbero necessari almeno 500 m<2 >di capannone per 48-36 ore di asciugatura. It is pointed out that also the process of the invention ? advantageous: in fact, many processes known in the art, such as the one described in IT1412994, provide for a manual deposition on a panel of fabric (e.g. 1 square metre) of the cork-based dispersion (compound), in fact an artisanal system that requires space enormous to allow the drying of the fabric with the cork-based dispersion (compound) applied, a material that is more? huge times related to the drying process pi? spaces, just as an example, to lay down and dry 50 m<2 >of fabric panels, at least 500 m<2 >of shed would be needed for 48-36 hours of drying.
Lo stato dell?arte nota influenza a livello qualitativo le performance da lotto a lotto produttivo, che non sono uniformi; inoltre il tessuto realizzato con il sopra menzionato brevetto presenta una scarsa resistenza alla flessione e bassa resistenza all?abrasione, oltre ad essere molto costoso in ragione del fatto che richiede personale qualificato, ampi spazi coperti e dunque con dei costi fissi molto elevati. The known state of the art influences the performances from batch to batch on a qualitative level, which are not uniform; moreover, the fabric made with the aforementioned patent has poor flexural strength and low abrasion resistance, as well as being very expensive due to the fact that it requires qualified personnel, large covered spaces and therefore with very high fixed costs.
E? un primo oggetto della presente invenzione: AND? a first object of the present invention:
un tessuto migliorato comprendente una base ed un rivestimento, detto tessuto essendo caratterizzato dal fatto di comprendere per la parte di rivestimento an improved fabric comprising a base and a lining, said fabric being characterized in that it comprises for the lining part
