The invention relates to slickened or siliconized flame resistant fiber blends that are well suited for use in mattresses, boxsprings, upholstered furniture, fiber-filled bed clothing, transportation seating or any end use application where a soft materials are desired for flame resistant (FR) purposes. Some of the fibers in the blend are slickened. The FR fibers incorporated into these blends include both char forming FR fibers and oxygen depleting FR fibers. FR char-forming fibers are those which exhibit little shrinkage when exposed to direct flame and are not spun from polymers manufactured with halogenated monomers. Oxygen depleting FR fibers are spun from polymers manufactured with halogenated monomers.

The invention relates to a nonwoven highloft flame barrier well suited for use in mattress, upholstered furniture and other end use applications where a highloft nonwoven material is desired for flame barrier purposes. A preferred nonwoven highloft flame barrier of the invention comprises a blend of fibers, that are inherently fire resistant and essentially nonshrinking to direct flame, with melamine fibers being preferred either alone or in conjunction with, for example, viscose rayon based fibers, fibers extruded from polymers made with halogenated monomers and preferably low-melt binder fibers, which are thermally activated in a highloft manufacturing process to provide low bulk density, resiliency and insulation properties in the end use application. The preferred fiber blends are designed to withstand extended periods of time exposed to open flame with minimal shrinkage of the char barrier; thereby preventing a flames from “breaking through” the char barrier and igniting underlying materials. Other component fibers can also, optionally, be included such as: natural fibers, to improve product economics in the end use application. The highloft flame barrier of this invention also allows for the manufacture of open flame resistant composite articles, while also permitting the continued use of conventional non-flame retardant dress cover fabrics, conventional non-flame retardant fiberfills and conventional non-flame retardant polyurethane foams.

Protective strips for use in the manufacture of upholstered furniture include a fastening strip portion, a cover strip portion and a hinge portion which flexibly connects the fastening and cover strip portions to one another. In use, the protective strips may be positioned such that a portion of the upholstery fabric is sandwiched between the fastening strip portion thereof and a portion of the furniture frame to which the fabric is to be attached. Suitable fasteners (e.g., staples, tacks, nails, brads and like fasteners) may then be physically driven through the fastening strip portion and the underlying fabric portion into the furniture frame and thereby fasten the fabric portion physically to the frame. Once the fastening strip portion has been fastened to the furniture frame, the remaining fabric portion may be doubled over the fastened tail portion which in turn causes the cover strip portion to be folded over the fastening strip portion. In such a manner, the heads of the fasteners are physically covered by the cover strip portion so as to prevent contact with the overlaid fabric. As such, rubbing of the fabric against the fastener heads is prevented so as to thereby preclude (or at least substantially minimize) fabric abrasion and wear.
