Flame resistant fabrics and garments made from same

InactiveUS20080057807A1Inexpensive and comfortable to wearerCotton-low durability-isWarp knittingAnimal housingPolymer scienceNatural fiber
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.

Nano-fiber covering yarn electrostatic spinning device and application thereof

The invention relates to a nano-fiber covering yarn electrostatic spinning device and application thereof. The nano-fiber covering yarn electrostatic spinning device comprises a twisting device, a backing-off device, a winding device, a double-needle electrostatic spinning device and a control system. The invention also provides a method for preparing electrostatic spinning nano-fiber covering yarns. The method comprises the following steps of performing spinning by using prepared spinning liquor through the double-needle electrostatic spinning device; depositing nano-fibers on a metal funnel and core yarns; uniformly winding the nano-fibers on the core yarns moving at constant speed by rotating the metal funnel; and finally forming the nano-fiber covering yarns of which skin layers are nano-fibers. The invention also provides another method for preparing a nano-fiber fabric. The other method for preparing the nano-fiber fabrics comprises the following steps of using water soluble yarns as core yarns; preparing the nano-fiber covering yarns by using the method; preparing a covering yarn fabric by using a textile technology; and dissolving the core yarns to obtain the nano-fiber fabric. The maneuverability is high; the nano-fiber covering yarn electrostatic spinning device is novel in structure; and the nano-fibers on surfaces of the covering yarns are arranged controllably.
