Description
Descrizione di un brevetto d'invenzione a nome: Description of an invention patent in the name:
Forma oggetto del presente trovato un tessuto a maglia elasticamente deformabile. The present invention relates to an elastically deformable knitted fabric.
I tessuti elastici a maglia in catena sono noti da molti anni e in particolare sono impiegati nel campo dell 'abbigliamento sportivo (ad esempio impiegati per i costumi da bagno ). La maggior parte di essi comprende una struttura contenente fili in elastomero immagliati con fili rigidi, ad esempio di poliammide. Elastic chain-knit fabrics have been known for many years and are used in particular in the field of sportswear (for example used for swimwear). Most of them comprise a structure containing elastomer yarns linked with rigid yarns, for example of polyamide.
Sono tuttavia stati immessi sul mercato da qualche anno fili in materia plastica termoretraibili quale il filo testurizzato in poliestere noto col nome commerciale di TREVIRA ESP oppure il filo noto come TIPO ELITE-PBT (polibutilenteref talato ). Tali fili in materia plastici: termoretraibile posseggono, se considerati a sè stante, una elevata elasticità e possono essere facilmente tinti . However, heat shrinkable plastic yarns such as the polyester textured yarn known under the trade name of TREVIRA ESP or the yarn known as TIPO ELITE-PBT (polybutylene terephthalate) have been placed on the market for some years. These thermo-shrinkable plastic yarns possess, if considered on their own, a high elasticity and can be easily dyed.
Attraverso l'impiego di tali fili possono essere realizzati capi d'abbigliamento (in particolare sportivo, come i costumi da bagno) che risultano ben aderire al corpo dell'utente. Tale caratteristica risulta alquanto importante ad esempio per i suddetti costumi soprattutto se impiegati nel campo agonistico o semiagonistico; l'aderenza al corpo dell'utente, infatti, consente all'atleta di muoversi più velocemente nell'acqua senza che nel suo costume penetri acqua rallentandone il movimento. Through the use of these yarns it is possible to make clothing (in particular sports clothing, such as swimwear) which adhere well to the user's body. This characteristic is quite important for example for the aforementioned costumes especially if used in the competitive or semi-competitive field; adherence to the user's body, in fact, allows the athlete to move faster in the water without water entering his costume, slowing down his movement.
L'impiego di tali fili, tuttavia, consente di ottenere manufatti aventi una elasticità molto limitata cosa che per la maggior parte degli utenti (ed in particolare quelli che non svolgono attività agonistiche) risulta essere una caratteristica negativa in quanto tale limitata elasticità comporta una conseguente limitata vestibilità e comodità di detti manufatti. The use of these threads, however, allows to obtain products having a very limited elasticity which for most users (and in particular those who do not perform competitive activities) is a negative characteristic as this limited elasticity leads to a consequent limited wearability and comfort of these artifacts.
Scopo del presente trovato è quello di offrire un manufatto tessuto a maglia in catena che, pur impiegando fili plastici termoretraibili, risulti essere elastico almeno quanto i ben noti manufatti tessuti a maglia contenenti elastomeri. The object of the present invention is to offer a knitted fabric product in a chain which, while using heat-shrinkable plastic yarns, is at least as elastic as the well-known knitted fabric articles containing elastomers.
Un altro scopo è quello di offrire un manufatto tessuto del tipo sopraindicato che sia di semplice realizzazione, di impiego affidabile e che presenti costi più contenuti rispetto ai tessuti con elastomeri noti. Another object is to offer a woven product of the type indicated above which is simple to manufacture, reliable in use and which has lower costs than fabrics with known elastomers.
Questi ed altri scopi vengono raggiunti da un tessuto a maglia in catena secondo le annesse rivendicazioni . These and other purposes are achieved by a chain-knitted fabric according to the attached claims.
Secondo il trovato, un tessuto a maglia in catena comprende una struttura definita in parte da fili rigidi (quali fili in poliestere) ed in parte da fili in materia plastica termoretraibile quali fili in polibutilentereftalato o in poliestere modificato, come ad esempio i fili aventi nome commerciale TREVIRA ESP già presenti sul mercato. In tale struttura, i suddetti fili sono immagliati in catena con intrecci di tipo unidirezionale. According to the invention, a chain-knitted fabric comprises a structure defined partly by rigid threads (such as polyester threads) and partly by heat-shrinkable plastic threads such as polybutylene terephthalate or modified polyester threads, such as for example the threads having the name commercial TREVIRA ESP already present on the market. In this structure, the aforesaid threads are intertwined in a chain with unidirectional interlacing.
Tale struttura viene ottenuta con una macchina da maglieria in catena ad esempio di tipo indemagliabile presentante pettini (alemno due, ciascuno operante su un tipo di filo) che formano armature che si spostano nello stesso senso nella stessa battuta. Preferibilmente i pettini lavorano così da realizzare una maglia in zig-zag doppio in parallelo unidirezionale; vantaggiosamente, però, alcuni punti possono essere in zig-zag semplice così da ottenere una struttura che in gran parte presenta intrecci a zig-zag doppi paralleli ed in minima parte intrecci a zig-zag semplice. Questi ultimi consentono di "legare" in modo ottimale gli intrecci a zig-zag doppio così da evitare l'apertura dei punti della struttura. This structure is obtained with a chain knitting machine, for example of the warp-knit type, having combs (at least two, each operating on a type of thread) which form weaves which move in the same direction in the same beat. Preferably the combs work in such a way as to provide a double zigzag link in unidirectional parallel; advantageously, however, some stitches can be in simple zig-zag so as to obtain a structure which in large part has double parallel zig-zag interlacing and, to a minimum, simple zig-zag interlacing. The latter allow to optimally "tie" the double zig-zag weaves so as to avoid opening the points of the structure.
In alternativa i pettini suddetti operano in modo da realizzare una maglia a spina (o spina Atlas), in parallelo o unidirezionale, semplice o doppia; eventualmente alcuni punti possono essere doppi o semplici. Alternatively, the aforesaid combs operate in such a way as to realize a pin link (or Atlas pin), in parallel or unidirectional, simple or double; possibly some points can be double or simple.
La particolare caratteristica della maglia in catena con intrecci unidirezionali utilizzante fili in materia plastica termoretraibile ha sorprendentemente permesso di ottenere un tessuto che presenta una notevole elasticità comparabile a quella dei migliori tessuti elastici con elastomeri; ciò malgrado fino ad ora tutti i tessuti a maglia in catena ottenuti con tali fili non presentassero tale caratteristica elastica. Tale nuova sorprendente caratteristica è proprio legata alla tipologia degli intrecci presente nel tessuto secondo il trovato; tale intrecci unidirezionali, infatti, consentono una ottimale estensione e ritrazione dei fili in materia plastica termoretraibile, fili che non risultano così "strozzati" nell'intreccio da quelli rigidi. Tali caratteristici intrecci non sono impiegati comunemente nei tessuti a maglia contenente fili in elastomero ovvero nei tessuti elastici a maglia in catena con tale filo termoretraibile presenti sul mercato in quanto questi ultimi presentano intrecci contrapposti. Analogamente, intrecci contrapposti sono pure presenti nei tessuti a maglia in catena noti contenenti fili in materia plastica non elastici. The particular characteristic of the chain link with unidirectional weaves using heat-shrink plastic threads has surprisingly made it possible to obtain a fabric which has a remarkable elasticity comparable to that of the best elastic fabrics with elastomers; nevertheless, until now, all the chain-knitted fabrics obtained with such yarns did not have this elastic characteristic. This new surprising feature is precisely linked to the type of weaves present in the fabric according to the invention; such unidirectional weaves, in fact, allow an optimal extension and retraction of the heat-shrink plastic threads, threads which are not so "choked" in the weaving by the rigid ones. These characteristic weaves are not commonly used in knitted fabrics containing elastomer threads or in elastic fabrics knitted in a chain with such heat-shrinkable thread available on the market since the latter have opposing weaves. Similarly, opposed weaves are also present in known chain knitted fabrics containing non-elastic plastic yarns.
La presente invenzione, pertanto, è ottenuta allontanandosi dalle comuni metodologie operative dell'uomo o tecnico del ramo e raggiunge risultati sorprendenti non preventivabili dalle usuali conoscenze di tale tecnico. The present invention, therefore, is obtained by moving away from the common operating methods of the man or person skilled in the art and achieves surprising results that cannot be foreseen by the usual knowledge of this technician.
In aggiunta, un tessuto ottenuto secondo il trovato ha una capacità di trattenere l'umidità inferiore a quella dei tessuti elastici noti, cosa che ne riduce i tempi di asciugatura con ovvi vantaggi per l'utente.' Inoltre, il tessuto così realizzato ha una notevole capacità di trattenere i colori nel tempo rispetto ai manufatti elastici già noti, detto tessuto potendo ovviamente essere sottoposto ad operazioni di nobilitazione (quali tintura, stampa, smerigliatura e similari) a cui usualmente i tessuti vengono sottoposti. In addition, a fabric obtained according to the invention has a lower moisture-retaining capacity than that of known elastic fabrics, which reduces its drying times with obvious advantages for the user. Furthermore, the fabric thus made has a remarkable ability to retain colors over time compared to the already known elastic products, said fabric being obviously able to be subjected to finishing operations (such as dyeing, printing, grinding and the like) to which the fabrics are usually subjected. .
