摘要： .epsilon.-Caprolactam is continuously recovered from carpet made from nylon 6 face fibers and a backing. The carpet is fed to a separator to prepare scrap containing nylon 6 and auxiliary materials. The scrap from the separator is fed to a depolymerizing reactor to produce an .epsilon.-caprolactam containing distillate and more auxiliary materials. The .epsilon.-caprolactam in the distillate is separated from other volatiles and purified. The auxiliary materials are also recovered or re-used.

摘要： 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.

摘要： 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.

摘要： An improved multifilamentary fibrous material is formed having solid particles of a matrix-forming thermosetting resin substantially uniformly dispersed among adjoining filaments in the absence of fusion bonding. The thermosetting resin particles initially are dispersed in an aqueous medium containing an effective amount of a dissolved polymeric binding agent and the viscosity of the medium subsequently is substantially increased to at least 50,000 cps. to form a gelled impregnation bath having a plastic flow characteristic with shear-thinning behavior wherein the thermosetting resin particles are substantially uniformly suspended. The resulting impregnation bath is caused to flow between the adjoining filaments of the multifilamentary fibrous material with a concomitant viscosity reduction which aids in the incorporation of the resin particles. The concentration of the aqueous medium in the product is controlled to yield a uniform, handleable, drapable, tacky, and highly stable product. Upon the application of heat and pressure the improved product can be transformed into a fiber-reinforced composite article wherein the thermosetting resin forms the matrix phase.
