In addition, the sol-gel approach is a high-purity process that leads to excellent homogeneity. Finally, the sol-gel approach is adaptable to producing films and fibers as well as bulk pieces. See Glass. The sol-gel process comprises solution, gelation, drying, and densification.


Preparation of fluorine-free water repellent finishing via ...

Cotton fabrics with durable hydrophobic properties were prepared by a novel method of thiol-ene click reaction. In this study, cotton fabrics were firstly treated with 3-Mercaptopropyltriethoxysilane (KH-580) to graft thiol-reactive groups on the cotton surface.


Application of Functional Nanoparticle Finishes on Cotton ...

cotton in the nano-scale. Water-repellent finish is used to protect textile fabrics from wetting, without adversely affecting the other properties such as air permeability of the finished fabrics. This is achieved by reducing the free energy at the textile surface. The degree to which the amount of water can be attached to a surface is


Waterrepellent finishing of cotton fabrics by ultraviolet ...

Cotton fabrics were waterrepellentfinished by radical ultraviolet curing of silicone and urethane acrylates with different formulations. The fabrics were impregnated with undiluted resins and with toluene solutions or water emulsions.
