Description
FABRIC AND YARN FOR PROTECTIVE GARMENTS
Field of the Invention The invention is directed to a fabric and a yarn used to make protective garments.
Background of the Invention Protective clothing refers to primary and secondary protective clothing (per ASTM Standard F1002-86). Primary protective clothing is designed for activities where significant exposure to molten substance splash, radiant heat, or flame is likely to occur.
Secondary protective clothing, on the other hand, is designed for continuous wear in areas where intermittent exposure to molten substance splash, radiant heat, and/or flame is possible.
Protective clothing in the work place is important because it is the employer's responsibility to identify risks and hazards in the workplace and seek out appropriate protective garments and equipment for the protection of workers. Common workplace hazards include, for example: flammable liquids, flammable soils, molten metals, sparks, slag from flame cutting, welding, open flames, high voltage electrical discharges, electric arc events, vapors from volatile liquids, and combustible dusts. These hazards may be encountered in foundries, at electrical utilities, in the chemical, oil, gas and petrochemical industries, in auto racing, to mention a few.
Fabrics have been developed for use in protective clothing.
Those fabrics may be made with treated fibers, inherently flame resistant fibers, or combinations thereof. A treated fiber is, typically, a conventional textile fiber that has been treated with a flame retardant, a chemical substance used to impart flame resistance. For example, two treated fibers are FR cotton or FR
rayon, both FR cellulosics. Inherently flame resistant fibers are those fibers that have flame resistance as an essential characteristic of the fiber. For example, inherently flame resistant fibers include: aramids, polyamide imides, melamines, polybenzimidazole (PBI), polyimides, polyphenylene benzodisoxazole (PBO), polyphenylene sulfide (PPS), polyetherether ketone (PEEK), and the like. Most often, these fibers are blended together to obtain a yarn for a fabric with a particular blend of properties.
Those properties include thermal protection, static resistance, comfort, durability, stability, appearance, ease of laundry maintenance, color, and relative cost.

Description of the Invention Fabrics are planar structures made of fibers and/or yarns assembled by various means such as weaving, knitting, tufting, felting, braiding, or bonding of webs to give the structure sufficient strength and other properties required for its intended use. A yarn is a generic term for a continuous strand of textile fibers, filaments, or materials in a form suitable for knitting, weaving, or otherwise intertwining to form a fabric. Yarn occurs, for example, in the following forms: (1) a number of fibers (e.g., staple) twisted together (spun yarn); (2) a number of filaments laid together without twist (a zero-twist yarn);
(3) a number of filaments laid together with a degree of twist; (4) a single filament with or without twist (a monofilament); or (5) a narrow strip of materials, such as paper, plastic film, or metal foil, with or without twist, intended for use in a textile construction.
The yarns and fabrics discussed hereinafter are preferably used as secondary protective clothing, but may be used otherwise, for example, as primary protective clothing.
The garments formed from these yarns and fabrics include, but are not limited to, 4a shirts, pants, coveralls, overalls, jackets, liners, coats, parkas, headwear, and footwear. The fabrics may be laminated or combined with other fabrics or materials to enhance functionality.
The fabrics are preferably woven or knitted. Woven fabrics include plain, twill, and satin weaves. Knitted fabrics include warp and weft knitted fabrics. The fabrics are preferably made of the yarn hereinafter described, but are not so limited. Instead, fabrics within the scope of present invention have a weight ratio of flame resistant fibers (i.e., inherently flame resistant fibers and treated fibers) to microdenier flame resistant fibers (i.e., inherently flame resistant fibers and treated fibers having microdeniers) is in the range of 4-9:2-6. Preferably, the ratio is 1:1. Alternatively, the ratio of inherently flame resistant fibers:microdenier flame resistant fibers:treated fibers is in the range of 1-3:2-6:3-6. Preferably, the ratio is 2:5:3. Other fibers may be added so long as the foregoing ratios are maintained.
For example, a conventional textile fiber could be added to a blend having the foregoing ratio.
The invention will be further described with reference to a yarn, it being understood that the foregoing fabric discussion is applicable to the following yarn as well as the following is applicable to foregoing fabric discussion.
The yarn comprises: 10-30% by weight of the yarn of an inherently flame resistant fiber (filament or staple); 20-60% by weight of a microdenier flame resistant fiber (filament or staple);
and 20-60% by weight of a treated fiber (filament or staple).
Preferably, the yarn comprises 20% of the inherently flame resistant fiber; 50% of the microdenier flame resistant fiber; and 30% of the treated fiber.
The inherently flame resistant fibers may be selected from the group consisting of: aramids, polyamide imides; melamines, polybenzimidazoles (PBI), polyimides, polyphenylene benzodisoxazoles (PBO), polyphenylene sulfides (PPS), polyether ketones (PEK), and polyetherether ketones (PEEK), and the like.
These fibers are known and commercially available. For example, aramids (meta-aramids and para-aramids) are available as TWARON , CONEX , and TECHNORA from Teijin Co. of Osaka, Japan; NOMEX and KEVLAR from DuPont of Wilmington, Delaware; P84 from Imitech of Austria; and KERMEL from Kermel Company of Colmar, France.
Melamines (melamine formaldehydes) are available as BASOFIL from Basofil Fibers LLC of Charlotte, North Carolina. PBI is available from Celanese Advanced Mateirals, Inc, of Charlotte, North Carolina.

(3) a number of filaments laid together with a degree of twist; (4) a single filament with or without twist (a monofilament); or (5) a narrow strip of materials, such as paper, plastic film, or metal foil, with or without twist, intended for use in a textile construction.
The yarns and fabrics discussed hereinafter are preferably used as secondary protective clothing, but may be used otherwise, for example, as primary protective clothing.
The garments formed from these yarns and fabrics include, but are not limited to, 4a shirts, pants, coveralls, overalls, jackets, liners, coats, parkas, headwear, and footwear. The fabrics may be laminated or combined with other fabrics or materials to enhance functionality.
The fabrics are preferably woven or knitted. Woven fabrics include plain, twill, and satin weaves. Knitted fabrics include warp and weft knitted fabrics. The fabrics are preferably made of the yarn hereinafter described, but are not so limited. Instead, fabrics within the scope of present invention have a weight ratio of flame resistant fibers (i.e., inherently flame resistant fibers and treated fibers) to microdenier flame resistant fibers (i.e., inherently flame resistant fibers and treated fibers having microdeniers) is in the range of 4-9:2-6. Preferably, the ratio is 1:1. Alternatively, the ratio of inherently flame resistant fibers:microdenier flame resistant fibers:treated fibers is in the range of 1-3:2-6:3-6. Preferably, the ratio is 2:5:3. Other fibers may be added so long as the foregoing ratios are maintained.
For example, a conventional textile fiber could be added to a blend having the foregoing ratio.
