FLAME RESISTANT MATELASSE FABRICS UTILIZING SPUN AND FILAMENT FLAME RESISTANT YARNS

摘要

The invention relates to the use of a flame resistant (FR) three-layer double-knit fabric, also know as a matelasse fabric. The top layer is of standard non-FR face yarn, the middle layer is of a FR filler spun yarn and the bottom layer is of a FR spun yarn or FR filament yarn. This FR matelasse fabric can be used to protect a mattress, foundation, upholstery cushion, pillow, office panel, transportation seat or any other article requiring FR protection. In this invention, a matelasse fabric is formed by circular double knitting a FR spun or FR filament yarn into the bottom portion of the fabric, utilizing a heavy cotton count FR filler spun yarn for the middle layer and using conventional non-FR yarns for the top layer. The invention has particular applicability in the formation of FR 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 FR upholstered furniture that requires passage of California's Test Bulletin 133 or British Standard 5852 using the crib 5 ignition source or higher.
