Abstract: A composite yarn for technical or industrial use, particularly suitable for textile webs, is uniformly coated with a polymer and exhibits improved fir behavior and improved resistance to sheath stripping. The yarn may be obtained by a process where a continuous yarn, obtained by spinning a large number of fibers, such as about 100 to 600 fibers made of an organic or inorganic material, of a suitable yarn diameter, such as between about 1 to 10 micrometers, is subjected to a process for mechanically opening the yarn by splaying, to uniformly spread out and separate the fibers, including inner layers of the fibers, without impairing functional properties of the yarn, simultaneously with or prior to coating of the fibers by a polymer material having a viscosity between 1000 and 10,000 mPa·s, and formed to have a circular cross-section and uniformly distributed fibers throughout the cross-section of the polymer material to limit desheathing of the yarn.

Abstract: The invention relates to a composite yarn including a filament yarn of an inorganic or organic material and a matrix of polymer material, the filament yarn being coated, extruded, or incorporated in the polymer material matrix. The matrix includes at least one foamed polymer. A composite yarn is characterized in that it has a core of an above-mentioned composite yarn and is coated, extruded or incorporated in a second polymer material matrix surrounding the core. Various methods may be used for producing the inventive yarns by coating and extrusion.

Abstract: A halogen-free flame retardant plastic composition, for coating a substrate, comprising an acrylic resin and an intumescent agent. It is in the form of plastisol, and comprises therefore a plasticizing medium wherein the acrylic resin and the intumescent agent are dispersed, said plastisol being formulated such that, in combination: the viscosity remains not more than 6000 mPa's, measured with a Brookfiled RVT viscometer at 20 revolutions per minute, its rheological behaviour is pseudo-plastic and Newtonian.
