abstract |
The invention relates to improved hydrophobicity and water protection of a fibrous fabric substrate (cotton, synthetics and/or their blends) by depositing a thin nanofiber layer and coating with a dispersion of fluoropolymers (fluorinated acrylic copolymers) that are alternative perfluorinated chemicals (PFCs) based on short-chain chemistry of varying chain length (C4, C6, C8, C10, C12, C14, etc.) perfluoroalkyl constituents. |
