Description

Tejido bielástico ignífugo para prendas contra el fuego.Bielastic fire retardant fabric for garments against fire.

Objeto de la invenciónObject of the invention

La presente invención, según se expresa en el enunciado de esta memoria descriptiva, se refiere a la realización de un tejido bi-elástico ignífugo, así como a su utilización en prendas de protección contra el fuego para uso de bomberos. Dicho tejido ha sido concebido y realizado en orden a obtener numerosas y notables ventajas respecto a otras prendas existentes con análoga finalidad.The present invention, as expressed in the set forth in this specification, refers to the realization of a flame retardant bi-elastic fabric, as well as its use in fire protection garments for the use of firefighters. Said fabric has been conceived and made in order to obtain numerous and notable advantages over other garments existing with similar purpose.

La utilización de dicho tejido bi-elástico tiene lugar en las axilas de la prenda, con el fin de dotar de una mayor movilidad en brazos y hombros al usuario de la misma. En ejecuciones alternativas dicho tejido bi-elástico podría utilizarse en otras partes de chaqueta o pantalón del traje de intervención de bom-
beros.The use of said bi-elastic fabric takes place in the armpits of the garment, in order to provide the user with greater mobility in arms and shoulders. In alternative embodiments said bi-elastic fabric could be used in other parts of jacket or pants of the pump intervention suit.

Antecedentes de la invenciónBackground of the invention

Las prendas de intervención de bomberos constan de varias capas de tejido superpuestas, dotando al mismo de un considerable peso y volumen. Con el inconveniente de reducir la movilidad de brazos y piernas de quienes las portan. En concreto el movimiento de los brazos se ve perjudicado al tener que "arrastrar" el peso del conjunto de la prenda.Firefighter intervention garments consist of of several layers of overlapping fabric, giving it a considerable weight and volume. With the inconvenience of reducing the mobility of arms and legs of those who carry them. Specifically the arm movement is impaired by having to "drag" the weight of the garment assembly.

En la actualidad la movilidad de brazos y hombros en chaquetones de intervención contra el fuego de bomberos se mejora mediante la incorporación de un fuelle de una o dos hojas, consistente en dar una mayor proporción del mismo tejido que conforma el chaquetón, en las axilas. De modo tal que al levantar el brazo dicho fuelle se despliegue permitiendo la movilidad del miembro sin arrastrar el cuerpo del chaquetón.Currently the mobility of arms and shoulders in fire fighting intervention jackets improvement by incorporating a bellows with one or two leaves, consisting of giving a greater proportion of the same tissue than make up the coat in the armpits. So that when raising the  said bellows arm is deployed allowing mobility of the member without dragging the body of the coat.

Este sistema presenta el inconveniente de su mayor peso y volumen. Al estar el brazo en su posición de descanso junto al cuerpo dicho fuelle forma unas arrugas bajo la axila perjudicando el confort del usuario.This system has the disadvantage of its Greater weight and volume. When the arm is in its resting position next to the body said bellows forms wrinkles under the armpit impairing user comfort.

Descripción de la invenciónDescription of the invention

El tejido de la invención tiene simultáneamente las características de elástico en las dos direcciones e ignífugo. Dicha combinación de características se consigue realizando la tejeduría con un hilo especial, producido mediante un recubrimiento en forma helicoidal de una fibra elastómera con aramida. Dicho recubrimiento tiene por finalidad proteger la fibra elastómera contra los efectos del calor, que de otro modo, le harían perder su elasticidad. Incorporando el citado hilo en trama y urdimbre se consigue un tejido de calada elástico en sentido longitudinal y transversal y capaz de soportar el fuego (según requerimiento de EN-UNE 469).The fabric of the invention simultaneously has The characteristics of elastic in both directions and flame retardant. This combination of features is achieved by performing the weaving with a special thread, produced by a coating in helical form of an elastomeric fiber with aramid. Saying Coating is intended to protect the elastomeric fiber against the effects of heat, which otherwise would make him lose his elasticity. Incorporating the aforementioned weft and warp thread get a stretch fabric in the longitudinal direction and transverse and able to withstand fire (as required by EN-UNE 469).

El chaquetón de intervención incorpora, en una realización concreta, en las axilas y en forma de media luna, el tejido elástico antes descrito. La incorporación de dicho tejido consigue dotar de movilidad en brazos y hombros al usuario de la prenda de protección contra el fuego sin necesidad de formar pliegues molestos y aligerando el peso de la misma.The intervention jacket incorporates, in a concrete realization, in the armpits and crescent shaped, the elastic fabric described above. The incorporation of said tissue manages to provide mobility in arms and shoulders to the user of the fire protection garment without forming annoying folds and lightening the weight of it.

Descripción de la forma de realización preferidaDescription of the preferred embodiment

El tejido se realiza incorporando hilo elástico protegido del calor tanto en urdimbre como en trama para dotarlo de elasticidad en ambas direcciones, longitudinal y transversal.The fabric is made incorporating elastic thread protected from heat in both warp and weft to provide it with elasticity in both directions, longitudinal and transverse.

En cada axila se incorporan dos piezas superpuestas, según figura 2, unidas por pespuntes longitudinales, a fin de dotar a la prenda de la resistencia al fuego requerida en la norma EN-UNE 469 y de la tracción requerida para devolver la manga a su punto de partida.In each armpit two pieces are incorporated superimposed, according to figure 2, joined by longitudinal stitching, in order to provide the garment with the fire resistance required in EN-UNE 469 standard and the traction required for return the sleeve to its starting point.
