Definitions
- the invention relates to the use of a flame resistant knit tube, made with either a seamless or seamed circular knit or a seamed or tubular warp knit fabric, used to protect a mattress, foundation, upholstery cushion, pillow, office panel, transportation seat or any other article requiring flame resistant protection.
- a tubular knit fabric is formed utilizing flame resistant yarn and then optionally heat-set to prevent curling during subsequent cuffing and processing. Heatsetting the knit fabric is especially preferred for circular knit constructions to prevent curling in subsequent processing.
- the knit tube is then cut to the length of the article to be flame protected, allowing enough additional length to sew a pocket closure on one end and a standard closure on the other end.
- one end of the tubular knit sock is sewn with a pocket closure seam, using a flame resistant thread or a suitable substitute.
- the open end of the tubular knit sock is then rolled up to the sewn pocket closure end so that it can be easily positioned over the article to be protected from flame.
- the rolled up knit sock is then unrolled down the length of the article to be flame protected.
- the second closure seam is then sewn with flame resistant thread, or a suitable substitute, over the open end of the article to completely encapsulate and protect the article.
- the invention has particular applicability in the formation of fire resistant foam mattresses and foundations that require passage of large open flame tests such as California's Test Bulletin 603 and Test Bulletin 129 and in the formation of fire resistant foam upholstery cushions that require passage of California's Test Bulletin 133 or British Standard 5852 using the crib 5 ignition source.
- FR chemically treated fabrics will self-extinguish and exhibit limited melt behavior when a flame is removed, they typically form brittle chars, shrink and crack open after exposure to a direct flame allowing the underlying materials to ignite.
- fabrics made with FR treated cotton, FR polyester and other FR treated fabrics are used in composite articles such as upholstered furniture and mattresses and foundations, these composite article are usually deemed unsuited for passing the more stringent open flame tests such as: California Test Bulletin 133 (TB 133), California Test Bulletin 129 "Flammability Test Procedure for Mattresses for use in Public Buildings", October 1992 (TB 129), California Test Bulletin 603 (TB603), and British Standard 5852 — Crib 5 (BS5 852) without the use of an additional flame barrier or FR backcoating materials.
- Some of the flame barrier fabrics currently being used with the goal to pass the more stringent open flame tests, such as TB 129, TB 133 and TB603 include: I) A woven polymer coated 100% fiberglass flame barrier (Sandel®
- thermoplastic polyvinyl halide composition such as polyvinyl chloride (Firegard® Seating Barriers, Intek; Firegard® Brand Products, Chiquola Fabrics, LLC, Alessandra FR barrier cloth, McKinnon-Land, LLC)
- the disadvantages of the above mentioned flame baffler solutions for more stringent open-flame applications in upholstered furniture, mattress, foundations and other fiber-filled applications include: a) Woven flame bafflers, especially when coated with FR materials, impart a stiff "hand" to the composite article, which negatively affect the feel of the final product.
- the term "flame barrier” means a product incorporated into or on top of a composite article that when tested with a composite type test method, such as: California Test Bulletin 129 (TB 129) or California Test Bulletin 603 (TB603) for mattresses and foundations and California Test Bulletin 133 (TB 133) for upholstered furniture, the flame barrier allows for the continued use of conventional materials such as dress cover fabrics, fiber-fillings and polyurethane foams, while still passing these stringent large open flame tests.
- flame bafflers made of the tubular knit flame barriers described in this invention can be made to pass less stringent open flame tests such California's Revised Test Bulletin 117 (TB 117 — draft 02/02 version) and British Standard 5852.
- a fire resistant yarn is converted to a circular or warp knit fabric.
- the fire resistant yams include open-end, ring, air-jet, corespun or other spun yarn types; where the staple fibers in the yarn are selected so that the blended fibers have a Limiting Oxygen Index (LOI) of at least 22 (as measured by ASTM D 2863).
- LOI Limiting Oxygen Index
- the staple fibers selected for blending consist of one or more fiber types selected from the following two categories:
- Inherently flame-retardant fibers such as; melamine (i.e. BASOFIL by Basofil Fibers LLC), meta-aramids such as poly
- m-phenylene isophthalamide for example, those sold under the tradenames NOMEX by E. I. Du Pont de Nemours and Co., TEIJINCONEX by Teijin Limited and FENYLENE by Russian State Complex; para-aramids such as poly (p- phenylene terephthalamide), for example, that sold under the tradename KEVLAR by E.

- a flame resistant yarn with a cotton count between 2's to 50's is produced with fibers selected from the above group and according to the Limiting Oxygen Index criteria described above.
- the flame resistant yarn is knitted into a circular or warp construction.
- a non-limiting list of specific knitting constructions that are applicable to this invention include; simplex tricot, double needle bar tricot, V bed, rib, interlock, double knit and jersey.
- Jersey knit constructions, that do not have seams and are suitable for this invention, can be made with flame resistant yarns that are converted into 6.5 ounces per square yard fabrics on knitting machines with diameters from 9 inches to 60 inches.
- the tubular jersey knit can then be heat-set to produce finished widths with controlled stretch. This is especially preferred for jersey, and other circular knits, that tend to curl when they are cut.
- the fabric must be seamed with flame resistant thread, or a suitable substitute, to form a knit tube.
- the knit tube is then cut to the length of the article to be flame protected, allowing enough additional length to sew a closure seams to both ends of the tubular knit sock.
- one end of the tubular knit sock is sewn with a pocket closure seam, using a flame resistant thread.
- the open end of the sewn tubular knit sock is rolled up to the pocket closure end so that it can be easily positioned over the article to be protected from flame.
- the rolled up knit tube sock is then unrolled down the length of the article to be flame protected.
- a second closure seam is then sewn with a flame resistant thread, or a suitable substitute, over the open end of the article to completely encapsulate and flame protect the article.
- This invention has particular applicability in the formation of fire resistant foam mattresses and foundations that require passage of large open flame tests such as California's Test Bulletin 603 and Test Bulletin 129 and in the formation of fire resistant foam upholstery cushions that require passage of California's Test Bulletin 133 or British Standard 5852, crib 5.
- a Murata air-jet spinning frame consisting of a dual core of continuous filament fiberglass and continuous nylon yarn wrapped with a triblend sliver of modacrylic (PROTEX PBX), melamine (BASOFIL) and polyester staple fibers to form a corespun yarn with a yarn count of 15.5' s.
- PROTEX PBX triblend sliver of modacrylic
- BASOFIL melamine
- polyester staple fibers to form a corespun yarn with a yarn count of 15.5' s.
- the above formed corespun yarn is then knitted into a 6.95 ounce per square yard 1 x 1 rib knit construction and seamed together with p-aramid (Kevlar) thread to form a tubular shape.
- the tubular knit sock is then cut to the length necessary to cover a 7" thick all-foam twin size mattress, consisting of a 4" base of standard polyurethane foam and a 3" top layer of viscoelastic polyurethane foam and both ends of the mattress.
- One end of the tubular knit sock is seamed together with p-aramid (KEVLAR) thread to form a pocket closure seam.
- the knit tube sock is rolled up from the open end to the pocket closure end and placed on one end of the all-foam mattress.
- the knit tube sock is then rolled down the all-foam mattress and the open end is then sewn closed with p-aramid (KEVLAE.) thread.
- the above constructed mattress was tested at Underwriters Laboratories (Northbrook, IL) according to California Test Bulletin 603.
- the Peak Rate of Heat Release was 55 KW (maximum allowable rate of heat release is 200KW) and the Total Heat Release was 8.0 MJ (maximum allowable in first 10 minutes is 25 MJ). This test was considered a significant pass of CAL TB 603.
- a flame resistant corespun yarn (ALES SANDRA, by McKinnon Land LLC) is produced on a Murata air-jet spinning frame, consisting of a dual core of continuous filament fiberglass and continuous nylon yarn wrapped with a triblend sliver of modacrylic (PROTEX PBX), melamine (BASOFIL) and polyester staple fibers to form a corespun yarn with a yarn count of 15.5' s.
