Benefits of technology

[0006] With the foregoing in mind, it is therefore an object of the invention to provide flame resistant fabric

Problems solved by technology

Therefore, the prior garments, which have tended to perform relatively well from the standpoint of protection and durability, have been extremely deficient in aesthetic characteristics such as wearer comfort.
For example, they are known to be stiff and to have a harsh handle, and they are generally considered to be hot and uncomfortable to the wearers.
Not only is the discomfort typically associated with these garments a source of displeasure to the wearers, but it may discourage t

[0035] Example A—A fabric was woven from 30 / 2 100% Nomex IIIA® air-jet spun yarns (95% Aramid, 3% Kevlar®, and 2% Nylon P-140 (from DuPont) with a twist multiple of 14 of the variety available from Pharr Yarns of McAdenville, N.C. in a 1×1 plain weave construction. The fabric was jet dyed in a conventional manner using cationic dyes of the variety conventionally recommended for the dyeing of the Nomex, and acid dyes of the variety commonly used to dye nylon (both of which will be readily appreciated by those of ordinary skill in the art. Dyeing was performed at approximately 266° F. for one hour. The fabric was then passed through a pad containing 1-½% Lurotex A-25 ethoxylated polyamide (distributed by BASF of Mount Olive, N.J.) and 1-½% Lubril QCX high molecular weight ethoxylated polyester manufactured by Tennessee Eastman (to facilitate stain release and wicking). The fabric was then dried in a conventional manner on a tenter frame at about 410° F. at a speed of approximately 25 ...

Abstract

Fabrics having improved aesthetic characteristics in addition to good FR characteristics and strength are described, as well as a method for making the fabrics. The fabrics are made by subjecting a fabric containing inherently flame resistant fibers to a fluid treatment process such that a fabric with good comfort and aesthetic characteristics is formed. In one form of the invention, the fabric comprises plied yarns, and the fluid treatment process serves to separate the plies from each other. The fabrics have a soft hand, good protective characteristics, good strength and durability, as well as good wicking and soil release characteristics.

Description

BACKGROUND OF THE INVENTION [0001] A variety of occupations require workers to come into close contact with hot equipment, hot substances open flames, and electric arcs and the like. For example, oil refinery, petro chemical workers, electricians, military personnel, etc. typically operate in such environments. In order to minimize their risk of injury from the hot elements, such workers typically wear flame resistant apparel. [0002] Flame resistant garments are generally made from flame resistant materials such as those made from aramid fibers (including meta-aramids and para-aramids), melamine fibers, or those treated with flame resistant “FR” chemistries. Prior protective garments have focused strictly on flame resistant protection and durability, since the garments must provide good protection to the wearer, and must withstand hazardous environments. In addition, because many garments are often laundered under industrial wash conditions, they must be capable of withstanding a nu...
