Abstract:
A suede-like micro-fibril finish is imparted to fibrillatable cellulosic materials by open width hydraulic treatment. Additional enhancement of the fabric finish is obtained by post hydraulic enzyme and wet processing treatments. Fluid treated fabrics of the invention are characterized by substantially uniform fibrillation of fibers within the fabric body and surface areas.
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.

Abstract:
Flame resistant stretch fabrics made from aramid fibers and elastomeric fibers and methods and systems for dyeing such fabrics while significantly retaining the stretch properties of the fabrics. Such methods and systems include the use of certain dye carriers not conventionally used in the aramid dyeing process that enable the fabric to be dyed under normal aramid dyeing conditions without eliminating or significantly impacting the stretch properties of the fabric. Such suitable dye carriers for use in the process include, but are not limited to, benzyl alcohol, butyl benzoate, n-butyl phthalimide, isopropyl phthalimide, dimethyl phthalate, biphenyl, monochlorotoluene, and combinations thereof. Phthalimides, and more particularly blends of n-butyl phthalimide and isopropyl phthalimide, have proven particularly effective at dyeing the aramid fibers at high temperatures while retaining the elastomeric properties of the fabric. The dyed flame resistant stretch fabrics of this invention can be used to construct, among other things, the entirety 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.
