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, comprising a mixture of the following fiber types:
- a) up to 85% inherently flame retardant fibers;
- b) 10-85% fibers made with halogenated monomers;
- c) 0-60% non-flame resistant fibers;
- d) wherein the amount of the FR component fiber from a) and b) is at least 25%;
- and
- e) wherein at least some of the fibers are slickened.
The flame resistant fiber blend of claim 5 wherein the modacrylic fibers include flame inhibiting chemicals such as antimony oxide and slickened versions thereof.
A non-woven flame resistant barrier formed of the following blend of fiber types wherein at least some of the fibers are slickened:
- a) up to 85% inherently flame retardant fibers;
- b) 10-85% fibers made with halogenated monomers;
- c) 0-60% non-FR natural fibers;
- d) 0-60% 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 FR fibers makeup at least 25% of the blend;
- and
- g) wherein at least some of the fibers are slickened.
