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 yam, the middle layer is of a FR filler spun yam and the bottom layer is of a FR spun yam 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 yam for the middle layer and using conventional non-FR yams 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. |
