Abstract
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.
Claims27
A flame resistant fiber blend for use in the production of a flame barrier, the fiber blend comprising:
- a) 10-85% by weight slickened inherently flame retardant fibers selected from the group consisting of melamines, flame retardant viscose rayons, and combinations thereof;
- b) 10-85% by weight fibers made with halogenated monomers;
- c) 0-60% by weight non-flame resistant synthetic fibers;
- d) 0-60% by weight non-flame resistant natural fibers:
- e) wherein the amount of slickened inherently flame retardant fibers and fibers made with halogenated monomers is at least 25% by weight;
- and
- f) wherein at least some of the non-flame resistant synthetic fibers or the non-flame resistant natural fibers are slickened.
A non-woven flame resistant barrier comprising a flame resistant fiber blend, the fiber blend comprising:
- a) 10-85% by weight slickened inherently flame retardant fibers selected from the group consisting of melamines, flame retardant viscose rayons, and combinations thereof;
- b) 10-85% by weight fibers made with halogenated monomers;
- c) 0-60% by weight non-FR natural fibers;
- d) 0-60% by weight non-FR synthetic fibers;
- e) wherein the fiber blend further includes 0-60% by weight of a binder component selected from the group consisting of low-melt binder fibers, halogenated binder resins, and combinations thereof;
- f) wherein the slickened inherently flame retardant fibers and the fibers made with halogenated monomers make up at least 25% by weight of the blend;
- and
- g) wherein at least some of the non-FR natural fibers or the non-FR synthetic fibers are slickened.
