The invention concerns glass fibers coated with a sizing composition. Said sizing composition, in particular obtained from an aqueous solution, comprises as adhesive film forming agents the combination: of at least one polyvinyl acetate A with low molecular weight; of at least one thermally self-cross linking polyvinyl acetate B, in an A/B weight ratio not less than 1.
L'invention concerne des fils de verre revêtus d'une composition d'ensimage. Ladite composition d'ensimage, notamment obtenue d partir d'une solution aqueuse, comprend comme agents filmogènes collants l'association d'au moins un acétate de polyvinyle A à bas poids moléculaire, d'au moins un copolymère d'acétate de polyvinyle B auto- réticulable thermiquement, dans un rapport pondéral A/B supérieur ou égal à 1.
