ABSTRACT:
The invention relates to a process for manufacturing continuous a glass fiber strand.
The process consists in depositing on the glass filaments which are in the process of being drawn a sizing composition of which the solvent content is less than 5 wt % of solvent selected from organic solvent and water, the solution comprising at least 70 wt % of a mixture of constituents which can be polymerized and/or crosslinked by heat treatment, at least 60 wt % of the constituents being constituents of which the molecular weight (Mw) is less than 750, less than 10 weight % being film-forming agents and 0 to 25 weight % being coupling agents, lubricants, stabilizers and initiators and/or catalysts, and in winding the strand or strands, formed by collection of the filaments, on a rotating support so as to form a wound package consisting of turns of strand coated with a non-polymerized sizing composition.
The strands are intended to reinforce thermoplastic or thermosetting organic substrates or substances of mineral origin.
