PendingCN122279969AImprove binding stabilityImprove waterproof durabilityPolymer scienceCyclodextrin
This invention relates to the field of functional textile materials technology, and discloses a fluorine-free waterproof fabric and its preparation process. The fluorine-free waterproof fabric is composed of a host-guest inclusion crosslinking type organosilicon synergistic film-forming agent, an organic small molecule film-forming component, a crosslinking promoter, a dispersant stabilizer, a softening agent, and a solvent. The host-guest inclusion crosslinking type organosilicon synergistic film-forming agent is prepared by forming a host-guest inclusion structure with β-cyclodextrin and adamantane carboxylic acid, followed by reactive modification with 3-isocyanate propyltriethoxysilane. The organic small molecule film-forming component is norbornene-2-carboxylic acid. Through host-guest inclusion, crosslinking, and organic small molecule synergistic film formation, a stable and dense fluorine-free waterproof functional layer is formed on the fabric surface. This invention significantly improves waterproof performance and its washability and abrasion resistance without using fluorine-containing compounds, while also maintaining the soft hand feel of the fabric, demonstrating good environmental friendliness and application prospects.
