Provided is a flame resistant drywall installation, especially those designed to meet ASTM E119. The installations comprise the use of fiberglass corespun flame resistant (FR) woven and fiberglass corespun stitchbonded nonwoven fabrics. The preferred forms of the woven and stitchbonded fabric used in this invention include:WOVEN FABRIC: A 3-8 opsy woven fabric consisting of fiberglass corespun yarns as described below.STITCHBONDED FABRIC: A 4-10 nonwoven batting of 100% cotton, 100% rayon, 100% lyocell, cotton/non-FR fiber blends, rayon/non-FR fiber blends or lyocell/non-FR fiber blends stitched with fiberglass corespun yarns as described below.Fiberglass corespun weaving and stitching yarns, for use in the invention, include those known in the textile industry as Alessandra® yarn (U.S. Pat. Nos. 6,146,759; 6,287,690; 6,410,140; 6,606,846; 6,553,749 by McKinnon Land LLC) and Firegard® yarn (by Springs Industries).The two fabric types mentioned above are used in tandom, between layers of conventional gypsum style drywall paneling to obtain a higher flame rating than would otherwise be able to be obtain in a layered drywall construction which does not include these fabrics. Conventional latex paint or flame resistant coating materials can be used to adhere the fabrics between the drywall paneling.

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. In this invention, a tubular knit fabric is formed utilizing flame resistant yam and then optionally heat-set to prevent curling during subsequent cutting and processing. Heat-setting 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. First, 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.

The invention relates to the use of a flame resistant three-layer double-knit or woven fabric, also know as a matelasse fabric. The top layer is of standard non-flame resistant face yarn, the middle layer is of flame resistant filler yarn and the bottom layer is of flame resistant core wrap spun yarn. This flame resistant matelasse fabric can be used to protect a mattress, foundation, mattress pad, pillow, comforter, upholstery cushion, pillow, office panel, transportation seat or any other article requiring flame resistant protection. In this invention, a matelasse fabric is formed by circular double knitting or weaving a flame resistant core spun yarn into the bottom portion of the fabric, utilizing a heavy cotton count flame resistant filler yarns for the middle layer and using conventional non-flame resistant yarns for the top layer. The invention has particular applicability in the formation of flame resistant mattresses and foundations that require passage of large open flame tests such as CPSC's 16 CFR part 1633, California's Test Bulletin 603 and Test Bulletin 129 and in the formation of flame resistant upholstered furniture that requires passage of California's Test Bulletin 133 or British Standard 5852 using the crib 5 ignition source or higher.
