    Abstract: The present invention describes a method of dissolving cellulose, said method comprising: dissolving cellulose in an alkali solution: —filtering the dissolved cellulose, thereby forming a filtered dissolved cellulose solution and a filter reject; —mixing said filter reject having a first viscosity value with a dissolution liquid having a second viscosity value, wherein the second viscosity value is lower than the first viscosity value, to provide a diluted reject stream having a third viscosity value being lower than the first viscosity value of the filter reject; and—separating inhomogeneities from the diluted reject stream.

    Abstract: Embodiments of the present invention relate to flame resistant fabrics formed with inherently flame resistant fibers that provide the requisite thermal and arc protection, that have improved comfort, and that, in some embodiments, are less expensive than other fabrics formed with inherently flame resistant fibers. Improved comfort and lower cost can be achieved by predominantly locating the inherently flame resistant fibers on the front face of the fabric to impart the requisite thermal and arc protection and predominantly locating the more comfortable (and less expensive) fibers on the back face of the fabric positioned next to the wearer. In this way, overall protection of the fabric is maintained while improving comfort. Some embodiments of such fabrics may also achieve NFPA 70E PPE Category 2 protection.

    Abstract: 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.
