    • Unique blends of fibers that incorporate synthetic cellulosic fibers to render fabrics made with such blends more durable than fabrics made with natural cellulosic fibers such as cotton. While more durable than cotton, the synthetic cellulosic fibers used in the blends are still inexpensive and comfortable to the wearer. Thus, the benefits of cotton (affordability and comfort) are still attained while a drawback of cotton—low durability—is avoided. In one embodiment, the fiber blend includes FR modacrylic fibers and synthetic cellulosic fibers, preferably, but not necessarily non-FR lyocell fibers such as TENCEL™ and TENCEL A100™. Other fibers may be added to the blend, including, but not limited to, additional types of inherently FR fibers, anti-static fibers, anti-microbial fibers, stretch fibers, and/or high tenacity fibers. The fiber blends disclosed herein may be used to form various types of FR fabrics. Desired colors may be imparted in a variety of ways and with a variety of dyes to the fabrics disclosed herein. Fabrics having the fibers blends disclosed herein can be used to construct the entirety of, or various portions of, a variety of protective garments for protecting the wearer against electrical arc flash and flames, including, but not limited to, coveralls, jumpsuits, shirts, jackets, vests, and trousers.
    • 合成纤维素纤维独特的纤维混合物,使得用这种共混物制成的织物比用天然纤维素纤维如棉花制成的织物更耐用。 虽然比棉花更耐用,但是在混合物中使用的合成纤维素纤维对于穿着者来说仍然是便宜和舒适的。 因此,棉花的耐久性缺点在于避免了棉花的好处(可承受性和舒适性)。 在一个实施方案中,纤维混合物包括FR改性聚丙烯腈纤维和合成纤维素纤维,优选但不一定是非FR溶胞酶纤维,例如TENCEL TM和TENCEL A100 TM。 可以将其它纤维加入到共混物中,包括但不限于其它类型的固有FR纤维,抗静电纤维,抗微生物纤维,拉伸纤维和/或高韧性纤维。 本文公开的纤维混合物可用于形成各种类型的FR织物。 期望的颜色可以以各种方式和本文公开的织物的各种染料赋予。 具有本文公开的纤维混合物的织物可用于构建各种防护服的整体或各部分,以保护佩戴者避免电弧闪光和火焰,包括但不限于工作服,连身裤,衬衫, 夹克,背心和裤子。

    • A procedure is described for extending the period of time during which a line leg (e.g., a pipeline) made of a material with a coefficient of thermal conductivity λR, in a fireproofing installation remains below a critical temperature and hence for increasing the T-rating value according to ASTM E814 (UL1479). A line leg is wrapped with a mesh, that includes a non-flammable material with a coefficient of thermal conductivity λG, directly adjacent to the bulkheading of a feedthrough opening in a component on both sides for wall feedthroughs and/or above the feedthrough opening for ceiling feedthroughs, subject to the condition that the coefficient of thermal conductivity λG is greater than the coefficient of thermal conductivity λG. The heat removal from a line leg can be supported easily and, in particular, applied on-site such that even line legs with good thermal conductivity can achieve a high T-rating value in the fire test.
    • 描述了一种用于延长在防火设备中由具有导热系数λR的材料制成的线腿(例如,管道)保持低于临界温度并因此用于增加T等级的时间段 价值根据ASTM E814(UL1479)。 线腿用网状物包裹,其中包括具有导热系数λG的不可燃材料,其直接邻近两侧的部件中的馈通开口的舱边,用于壁馈通和/或穿通开口上方, 天花板馈通,条件是导热系数λG大于导热系数λG。 可以容易地支撑从腿部排出的热量,特别是现场应用,使得具有良好导热性的均匀线腿在火测试中可获得高的T值。
