The invention relates to a reinforcing textile thread () for an inflatable sail, such as a rigging sail or a flight sail, including a plurality of filaments which are agglutinated so as to form an elongate unitary body (), and a binder () which ensures the cohesion among at least some of the filaments () of the unitary body (), and which consists of a coating material. In order to guarantee an effective, directed reinforcement effect within an inflatable sail without limiting the lifespan of said sail, the unitary body has, in the cross-section thereof, an oblong outline, wherein the ratio of the maximum width (e) of said outline, which corresponds to a thickness of the unitary body, to the maximum length (l) of said outline, which corresponds to a width of the unitary body, is less than 0.06, a plurality of filaments () being arranged in series over the thickness of the unitary body.

Reinforcing textile thread for an inflatable sail, and rigging sail comprising such reinforcing textile threads

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&#xb7;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.

Composite yarn, method for obtaining same and resulting textile structure

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.
