Benefits of technology

[0005] It is an object of the present invention to provide a simple process for coating textile surfaces with a continuous metal oxide without altering the appearance of the textile.

Problems solved by technology

Present technologies such as impregnation coating of dispersed nanoparticles suffer from low adhesion between the oxide coating and the textile surface and hence poor wash-fastness results.

Embodiment Construction

[0023] A cotton substrate of 10.times.10 cm was dried at 100.degree. C. for 10 minutes. The dried cotton substrate was then dip-coated in the prepared sol for 30 seconds, padded at 2,7 kg per square centimetre and dried at 80.degree. C. for 10 minutes and then finally cured at 150.degree. C. for five minutes.

Abstract

A process for chemically bonding an oxide matrix to a textile surface, comprises providing a dry textile substrate, coating the substrate with a nanosol preparation, and curing the coated substrate.

Description

[0001] The present invention relates to multifunctional nanostructural surface treatment for textiles. More particularly, although not exclusively, the invention relates to the surface treatment of textiles adopting a Sol-gel reaction scheme. The invention relates to a simple, fast and low-cost finishing process for textiles using a metal oxide matrix providing improved surface properties. Properties to be improved might be ultraviolet filtering, hydrophilicity, self-cleaning, antimicrobial and deodorising characteristics.[0002] Applications of the invention exist in the production of smart textiles with tailor-made end uses addressing environmental protection and hygienic aspects.[0003] Present technologies such as impregnation coating of dispersed nanoparticles suffer from low adhesion between the oxide coating and the textile surface and hence poor wash-fastness results. The present invention, on the other hand allows for chemical bonding between the oxide matrix and the textile ...
