A high-strength, heat-resistant organic fiber and textile product each comprising or having coated thereon an aqueous emulsion is provided. The emulsion comprises or is produced from a fluorocarbon silane or an emulsion, said emulsion comprises or is produced from (1) a fluorocarbon silane or its hydrolyzate, (2) water, and (3) optionally a surfactant, an alkoxysilane compound, catalyst, or combinations of two or more thereof; said fluorocarbon silane having the formula Rf-(CH2)p-Si{-(O-CH2CH2)n-OR1}3; Rf is a C3-18 perfluoroalkyl group or combinations of two or more thereof; each R1 is independently one or more C1-3 alkyl groups; p is 2 to 4; and n is 2 to 10. Also disclosed is a process for producing the emulsion, the fiber, and the textile product.

L'invention concerne une fibre organique et un produit textile thermorésistants haute ténacité qui comprennent ou sont enrobés tous deux d'une émulsion aqueuse. La couche d'enrobage comprend un silane fluorocarburé ou une émulsion, ou est préparé à partir de ces derniers. L'émulsion comprend un (1) silane de fluorocarbone ou un hydrolysat de celui- ci, (2) de l'eau, et (3) éventuellement un tensioactif, un composé alcoxysilane, un catalyseur ou des combinaison d'au moins deux de ceux-ci, ou est préparée à partir de ces composants. Ledit silane fluorocarboné présente la formule R¿f?-(CH¿2?)¿p?-Si{-(O-CH¿2?CH¿2?)¿n?-OR?1¿}¿3?, dans laquelle R¿f? représente un groupe perfluoroalkyle C¿3-18? ou des combinaisons d'au moins deux de ceux-ci, et chaque R?1¿ représente séparément un ou plusieurs groupes alkyle C¿1-3?, p représente un nombre de 2 à 4; et n un nombre de 2 à 10. L'invention concerne également un procédé permettant de produire cette émulsion, cette fibre et ce produit textile.
