Definitions
- flame retardant also referred to as fire resistant, fabrics that can be used to make clothing suitable for people who work near flames, high temperatures, or electric arc flashes.
- an effective flame retardant fabric should be durable, comfortable, and produced at low cost.
- fabrics made of inherently flame retardant fibers have been very useful in protective garments, certain characteristics of these fibers present problems. For instance, these fibers can be difficult to dye, provide uncomfortable fabric textures, and are expensive.
- inherently flame retardant fibers have been blended with fibers made of other materials. Fiber blending can be used to obtain an end fabric that combines the beneficial characteristics of each of the constituent fibers. However, such blending often comes at the expense of durability and thermal performance.
- Fabrics made from the fiber blends and yarns discussed above either naturally suffer from poor resistance to abrasion or, as disclosed in U.S. Pat. No. 4,920,000 (Green) issued on Apr. 24, 1990, utilize a large percentage of cotton fiber, which has very low abrasion resistance.
- Fire protective clothing and garments are normally used in harsh environments so any improvement in abrasion resistance of the fabrics used in those garments is important and desired. There is therefore, a need for flame retardant fiber blends, yarns, and fabrics that have improved abrasion resistance.
- the invention is an intimate blend of staple fibers comprising 10 to 75 parts by weight of at least one aramid staple fiber, 15 to 80 parts by weight of at least one modacrylic staple fiber, and 5 to 30 parts by weight of at least one polyamide staple fiber.
- the invention is an intimate blend of staple fibers comprising 20 to 40 parts by weight of at least one aramid staple fiber, 50 to 80 parts by weight of at least one modacrylic staple fiber, and 15 to 20 parts by weight of at least one polyamide staple fiber.
- the invention is one of the intimate blends described above, wherein the at least one aramid staple fiber is poly(metaphenylene isophthalamide) and the at least one modacrylic staple fiber is a copolymer of acrylonitrile and vinylidene chloride.
- the modacrylic staple fiber of this invention preferably contains an antimony additive.
- the preferred antimony additive is an antimony oxide.
- the intimate blends of this invention may be used to make a yarn, which in turn may be used to make a flame retardant fabric for use in flame retardant articles such as clothing.
- An intimate blend of staple fibers of this invention comprises aramid fibers, modacrylic fibers, and polyamide fibers.
- the proportions of each component are important to achieve the necessary combination of physical qualities.
- timate blend is meant that two or more fiber classes are blended prior to spinning a yarn.
- the intimate blend is formed by combining aramid fibers, modacrylic fibers, and polyamide fibers in the fiber form, and then spinning into a single strand of yarn.
- yarn is meant an assemblage of fibers spun or twisted together to form a continuous strand, which can be used in weaving, knitting, braiding, or plaiting, or otherwise made into a textile material or fabric.
- Such yarns can be made by conventional methods for spinning staple fibers into yarns, such as, for example, ring-spinning, or higher speed air spinning techniques such as Murata air-jet spinning where air is used to twist the staple into a yarn.
- the intimate blend of staple fibers of this invention includes aramid fibers, which are inherently flame retardant.
- aramid fiber is meant one or more fibers made from one or more aromatic polyamides, wherein at least 85% of the amide (—CONH—) linkages are attached directly to two aromatic rings.
- Aromatic polyamides are formed by reactions of aromatic diacid chlorides with aromatic diamines to produce amide linkages in an amide solvent.
- Aramid fibers may be spun by dry or wet spinning using any number of processes, however, U.S. Pat. Nos.
- Aramid fibers are typically available in two distinct classes, namely meta-aramid fibers, or m-aramid fibers, one of which is composed of poly(metaphenylene isophthalamide), which is also referred to as MPD-I, and para-aramid fibers, or p-aramid fibers, one of which is composed of poly(paraphenylene terephthalamide), also referred to as PPD-T.
- Meta-aramid fibers are currently available from E. I. du Pont de Nemours of Wilmington, Del.
- NOMEX® in several forms under the trademark NOMEX®: NOMEX T-450® is 100% meta-aramid; NOMEX T-455® is a blend of 95% NOMEX® and 5% KEVLAR® (para-aramid); and NOMEX IIIA® (also known as NOMEX T-462®) is 93% NOMEX®, 5% KEVLAR®, and 2% carbon core nylon.
- NOMEX T-450® is 100% meta-aramid
- NOMEX T-455® is a blend of 95% NOMEX® and 5% KEVLAR® (para-aramid)
- NOMEX IIIA® also known as NOMEX T-462®
- meta-aramid fibers are available under the trademarks CONEX® and APYEILO which are produced by Teijin, Ltd. of Tokyo, Japan and Unitika, Ltd. of Osaka, Japan, respectively.
- Para-aramid fibers are currently available under the trademarks KEVLAR® from E.I. du Pont de Nemours of Wilmington
- TECHNORA® fiber which is available from Teijin Ltd. of Tokyo, Japan, and is made from copoly(p-phenylene/3,4′diphenyl ester terephthalamide), is considered a para-aramid fiber.
- the at least one aramid staple fiber is poly(metaphenylene isophthalamide).
- the intimate blend of staple fibers of this invention also includes modacrylic fibers.
- Modacrylic fibers are manufactured fibers in which the fiberforming substance is any long chain synthetic polymer composed of less than 85%, but at least 35%, by weight of acrylonitrile (—CH 2 CH[CN]—) x , units.
- Modacrylic fibers are made from resins that are copolymers (combinations) of acrylonitrile and halogen-containing compounds, such as vinyl chloride, vinylidene chloride or vinyl bromide.
- Modacrylic fibers are inherently flame retardant because they are copolymerized with these other compounds such as vinyl chloride, vinylidene chloride, or vinyl bromide.
- Modacrylic fibers are commercially available under various trademarks, such as Protex® (ACN/polyvinylidene chloride co-polymer), which is available from Kaneka Corporation of Osaka, Japan.
- the at least one modacrylic fiber is a copolymer of acrylonitrile and vinylidene chloride.
- the modacrylic staple fibers of this invention preferably contain an antimony additive.
- the preferred antimony additive is an antimony oxide, preferably added in an amount greater than two percent by weight.
- polyamide fibers are meant one or more fibers made from one or more aliphatic polyamide polymers, generically referred to as nylon. Examples include polyhexamethylene adipamide (nylon 66), polycaprolactam (nylon 6), polybutyrolactam (nylon 4), poly(9-aminononanoic acid) (nylon 9), polyenantholactam (nylon 7), polycapryllactam (nylon 8), and polyhexamethylene sebacamide (nylon 6, 10).
- Nylon fibers are generally spun by extrusion of a melt of the polymer through a capillary into a gaseous congealing medium.
- nylon is the polyamide fiber in the intimate blend of staple fibers forming a yarn
- such yarn preferably is used as the warp yarn when forming a fabric to enhance protection against soft surface abrasion in the finished fabric or garment made from such fabric.
- the fabrics or garments of this invention are expected to have more than ten percent higher resistance to abrasion compared to similar fabrics without nylon, as measured in cycles to failure according to the Abrasion Resistance Test described below.
- too much nylon in a fabric will cause the fabric to become stiff and lose drape when the fabric is exposed briefly to high temperatures.
- nylon fiber has a linear density from 1 to 3 dtex. In another embodiment the nylon fiber has a linear density from 1 to 1.5 dtex. In yet another embodiment the nylon fiber has a linear density of about 1.1 dtex.
- the intimate blend of staple fibers of this invention can be used to make yarns and fabrics that are flame retardant. These yarns and fabrics can be used to make flame retardant articles, such as flame retardant garments and clothing, which are particularly useful for firefighters and other workers who are put in close proximity to flames, high temperatures, or electric arc flashes.
- flame retardant is meant that the fabric does not support flame in air after coming in contact with a flame for a short period of time. More precisely, “flame retardant” can be defined in terms of the Vertical Flame Test, described below. Flame retardant fabrics preferably have a char length of less than six inches after a twelve second exposure to a flame.
- flame retardant flame retardant
- fire retardant fire retardant
- fire resistant references to “flame retardant” compounds, fibers, yarns, fabric, and garments in the present invention could be described identically as “flame resistant,” “fire retardant,” or “fire resistant.”
- Staple fibers for use in spinning yarns are generally of a particular length and of a particular linear density.
- synthetic fiber staple lengths of 2.5 to 15 centimeters (1 to 6 inches) and as long as 25 centimeters (10 inches) can be used, and lengths of 3.8 to 11.4 centimeters (1.5 to 4.5 inches) are preferred.
- Yarns made from such fibers having staple lengths of less than 2.5 centimeters have been found to require excessively high levels of twist to maintain strength for processing. Yarns made from such fibers having staple lengths of more than 15 centimeters are more difficult to make due to the tendency for long staple fibers to become entangled and broken, resulting in short fibers.
- the synthetic staple fibers can be crimped or not, as desired for any particular purpose.
- the staple fibers of this invention are generally made by cutting continuous filaments to certain predetermined lengths. However, staple fibers can be made by other means, such as by stretch-breaking, and yarns can be made from such fibers as well as from a variety or distribution of different staple fiber lengths.
- the yarn of this invention can be used to make a flame retardant fabric, which is a cloth produced by weaving, knitting, or otherwise combining the yarn of this invention.
- Flame retardant fabrics can be constructed having warp yarn comprising the yarns of this invention, fill yarn comprising the yarns of this invention, or both warp and fill yarns comprising the yarns of this invention.
- fabrics use the yarn of this invention in only one direction (i.e., as only fill or only warp), other suitable yarns may be used in the other direction according to the desired fabric characteristics.
- the yarn of this invention is used in the warp direction since warp yarn typically forms most of the direct contact surface of a fabric. This translates into better abrasion performance of the outer surface of the fabric in garment form.
- the flame retardant fabric has a basis weight of from 4 and 15 ounces per square yard. In another embodiment of this invention the flame retardant fabric has a basis weight of from 5.5 to 11 ounces per square yard.
- Such fabrics can be made into articles of clothing, such as shirts, pants, coveralls, aprons, jacket, or any other single or multi-layer form for flash fire or electric arc protection.
- TPP Thermal Protective Performance Test
- the predicted protective performance of a fabric in heat and flame was measured using the “Thermal Protective Performance Test” (NFPA 2112).
- NFPA 2112 Thermal Protective Performance Test
- a flame was directed at a section of fabric mounted in a horizontal position at a specified heat flux (typically 84 kW/m 2 ).
- the test measures the transmitted heat energy from the source through the specimen using a copper slug calorimeter with no space between the fabric and heat source.
- the test endpoint was characterized by the time required to attain a predicted second-degree skin burn injury using a simplified model developed by Stoll & Chianta, “Transactions New York Academy Science”, 1971, 33 p 649.
- TPP value The value assigned to a specimen in this test, denoted as the “TPP value,” is the total heat energy required to attain the endpoint, or the direct heat source exposure time to the predicted burn injury multiplied by the incident heat flux. Higher TPP values denote better insulation performance.
- the “Vertical Flame Test” (ASTM D6413) is generally used as a screening test to determine whether a fabric burns, as a predictor for whether an article of clothing has any flame retarding properties. According to the test, a 3 ⁇ 12 inch section of fabric was mounted vertically and a specified flame was applied to its lower edge for twelve seconds. The response of the fabric to the flame exposure was recorded. The length of the fabric that was burned or charred was measured. Times for afterflame (i.e., the continued burning of the fabric section after removing the test flame) and afterglow (characterized by smoldering of the fabric section after removing the test flame) were also measured. Additionally, observations regarding melting and dripping from the fabric section were recorded.
- afterflame i.e., the continued burning of the fabric section after removing the test flame
- afterglow characterized by smoldering of the fabric section after removing the test flame
- a fabric can be considered flame retardant, or fire resistant, if it has a char length of less than six inches after a twelve second exposure to a flame.
- Abrasion Resistance Test Abrasion resistance was determined using ASTM method D3884, with a H-18 wheel, 500 gms load on a Taber abrasion resistance meter available from Teledyne Taber, 455 Bryant St., North Tonawanda, N.Y. 14120. Taber abrasion resistance was reported as cycles to failure.
- Tear Strength Test The tear strength measurement is based on ASTM D 5587. The tear strength of textile fabrics was measured by the trapezoid procedure using a recording constant-rate-of-extension-type (CRE) tensile testing machine. Tear strength, as measured in this test method, requires that the tear be initiated before testing. The specimen was slit at the center of the smallest base of the trapezoid to start the tear. The nonparallel sides of the marked trapezoid were clamped in parallel jaws of a tensile testing machine. The separation of the jaws was increased continuously to apply a force to propagate the tear across the specimen. At the same time, the force developed was recorded. The force to continue the tear was calculated from autographic chart recorders or microprocessor data collection systems. Two calculations for trapezoid tearing strength were provided: the single-peak force and the average of five highest peak forces. For the examples here, the single-peak force was used.
- CRE constant-rate-of-extension-type
- the grab strength measurement which is a determination of breaking strength and elongation of fabric or other sheet materials, is based on ASTM D5034. A 100 mm (4.0 in.) wide specimen was mounted centrally in clamps of a tensile testing machine and a force applied until the specimen broke. Values for the breaking force and the elongation of the test specimen were obtained from machine scales or a computer interfaced with testing machine.
