Estimating the term…
The invention relates to a method for coating a textile material, said method comprising the following steps: a) at least one cycle of impregnating the textile material with a sol-gel adhesion formulation, said sol-gel adhesion formulation being free of polycarboxylic acid; b) at least one cycle of drying the impregnated textile material obtained in step a); c) at least one cycle of impregnating the dried textile material obtained in step b) with an omniphobic or hydrophobic sol-gel formulation comprising sulphamic acid, said omniphobic or hydrophobic sol-gel formulation being different from the sol-gel adhesion formulation; d) at least one cycle of drying the impregnated textile material obtained in step c).
1-29. (canceled)
A process for coating a textile material, said process comprising the following steps:
A sol-gel bonding formulation comprising at least two silylated precursors, a first precursor being chosen from tetramethoxysilane (TMOS), tetraethoxysilane (TEOS), and a second precursor chosen from (3-glycidyloxypropyl)trimethoxysilane (GPTMOS), (3-glycidyloxypropyl)triethoxysilane (GPTEOS) and aminopropyltriethoxysilane,
An omniphobic sol-gel formulation comprising at least one silylated precursor chosen from 1H,1H,2H,2H-perfluorodecyltriethoxysilane (17FTEOS), 1H,H,H,H-perfluorooctyltriethoxysilane (13FTEOS), 1H,1H,2H,2H-perfluorooctyltrimethoxysilane (13FTMOS) and 1H,1H,2H,2H-perfluorodecyltrimethoxysilane (17FTMOS), or a mixture of one or more of these precursors with tetraethoxysilane (TEOS), and comprising sulfamic acid.
\A hydrophobic sol-gel formulation comprising at least one silylated precursor chosen from hexadecyltriethoxysilane (HDTEOS), n-octadecyltriethoxysilane (ODTEOS), n-decyltriethoxysilane (DTEOS) and dodecyltriethoxysilane (DDTEOS), or a mixture of one or more of these precursors with tetraethoxysilane (TEOS), and comprising sulfamic acid.
