Definitions

  • the invention is directed to a fabric and a yarn used to make protective garments.
  • 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.
  • 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.
  • 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.
  • PBI GOLD® is a 40% PBI/60% aramid blend (all % are by weight of the fabric).
  • NOMEX® is a blend of 95% meta-aramid (NOMEX) fiber/5% para-aramid (KEVLAR) fiber.
  • NOMEX IIIA is a blend of 93% meta-aramid (NOMEX) fiber/5% para-aramid (KEVLAR) fiber/2% static dissipative fiber.
  • COMFORT BLEND® is 65% NOMEX IIIA/35% FR rayon blend.
  • NOMEX Freestyle is 93% NOMEX IIIA/5% para-aramid (KEVLAR) fiber/2% antistatic fiber.
  • INDURA ULTRASOFT is 88% FR cotton/12% nylon blend. Each of these fabrics has its own unique blend of properties. Flame Resistant Protective Apparel, An Industry Update 2001 / 2002, Bulwark Protective Apparel, a Division of VF Workwear, Inc., Arlington, TN, incorporated herein by reference.
  • US-B-6 489 256 discloses a fire escape blanket and other melamine resin containing compositions and products with fire blocking properties.
  • the product has, at its broadest range, about 15-80 parts by weight a melamine resin, up to about 80 parts by weight an aramid fiber, and up to about 80 parts by weight a modacrylic fiber.
  • a fiber fabric useful for flame-resistant garment is shown, which is composed of yarns comprising a blend of 65 to 95% by weight of an aromatic polyamide fiber-containing fiber component with 5 to 40% by weight of a polyester fiber component.
  • the aromatic polyamide fiber containing fiber component comprising 50 to 100% by weigth of aromatic polyamide fibers and 0 to 50% by weight of cellulose fibers and the fiber fabric having a limiting oxygen index of 26 or more.
  • the yarn may comprise an aramid fiber (denier 0.4-3), FR cellulosic fiber, and a polyester fiber.
  • the present invention is a yarn or fabric useful in protective garments.
  • the yarn or fabric is made of flame resistant fibers and microdenier flame resistant fibers.
  • the flame resistant fibers are selected from the group consisting of inherently flame resistant fibers, treated fibers, and combinations thereof.
  • the microdenier flame resistant fibers are selected from the group consisting of microdenier inherently flame resistant fibers, microdenier treated fibers, and combinations thereof.
  • the weight ratio of said flame resistant fibers to said microdenier flame resistant fibers is in the range of 4-9:2-6.
  • 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.
  • a number of fibers e.g., staple
  • filaments laid together without twist a zero-twist yarn
  • 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, 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.
  • the ratio of inherently flame resistant fibers:microdenier flame resistant fibers:treated fibers is in the range of 1-3:2-6:3-6.
  • 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 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).
  • 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.
