Junto con la carga admisible, que se manifiesta en la resistencia a la rotura del material utilizado, son interesantes una buena mecanizabilidad y, en función del propósito de utilización, un grosor pequeño de material así como una buena capacidad de aislamiento térmico o estanqueidad al polvo, actividad respiratoria, propiedades de transmisión de humedad y de lavado. Hasta ahora se han venido utilizando como trajes protectores en el trabajo materiales textiles elaborados a partir de diferentes mezclas de fibras, que debido a su estructura textil tienen tendencia a deshilacharse o desflecarse y, por tanto, deben ser cosidos. Al mismo tiempo en los materiales textiles con respecto a su resistencia debe ser tenida en cuenta también la dirección de las fibras del tejido. Estos inconvenientes no se presentan si se trata de una tela no tejida como la del documento US 5 970 583.For protective suits at work you They set very different requirements. Along with the load admissible, which manifests itself in the resistance to breakage of the material used, good machinability are interesting and, depending on the purpose of use, a small thickness of material as well as a good thermal insulation capacity or dust tightness, respiratory activity, properties of moisture transmission and washing. So far they have come using as protective clothing at work materials textiles made from different fiber blends, which due to their textile structure they tend to fray or deflected and therefore must be sewn. At the same time in the textile materials with respect to its resistance must be taken also take into account the direction of the fibers of the fabric. These Disadvantages do not occur if it is a non-woven fabric as in document US 5 970 583.
